Another protagonist was released September 28 two-car Toyota Corolla of 2017.

Release of the most anticipated is a corolla brand new 1.2T model, new cars Toyota new D-4T engines, is said to have better performance in terms of fuel consumption.

No change in the overall appearance of the Basic, keep two versions of 1.6L, 1.8L, the naturally-aspirated models, officials said 1.2T 5.4L fuel consumption per hundred kilometers, specifically how to also let us wait.

Version 3, the Honda Accord Hybrid

Price: 239,800-279,800 RMB

With Toyota two-car market, Honda is not a sign of weakness, released a hybrid version of the accord.

Appearance with the cash, though there are some differences in details.

Unlike cash accord rear wing

On behalf of hybrid trailer label

Interior and cash is not very different, electronic keys instead of entity retaining the dashboard reveals a mixed atmosphere.

Hybrid Edition models in the series as a whole is high, and offers air purifiers, front seat ventilation, rear sunshade and other configurations.

Honda i-MMD the Atkinson-cycle engine hybrid system equipped with a 2.0L (107-kilowatt, 175 nm; motor 135-kilowatt, 315 nm), official fuel consumption of only 4.2L per hundred kilometers, less than the two-engine Camry.

Taken together, the hybrid version of the accord 239,800 introductory price is quite reasonable, two-engine Camry Toyota would become its main competitors. In addition, Guangzhou, Tianjin and other areas have been included in the scope of new energy vehicles the hybrid version of the accord, car will enjoy benefits such as subsidies, of friends interested in mixing a trend like this, you can take a look at ~

New generation 4, Dongfeng Peugeot 308

Price: 99,700 159,700

On September 25, the new generation of Peugeot 308 official listing.

Wei electric super car track testing McLaren how Jiyan

Today United Kingdom fans on Twitter and the ins released Wei electric super car in United Kingdom Speedway test photos. Results of McLaren's official Twitter quickly forward, along with the sentence: what do you think? Homemade electric car core family tree the names

According to the first set of performance indicators, become the electric super car maximum power output up to 1360 horsepower (1000kW), a top speed of over 300km/h, hundred mph in less than 3 seconds. On other performance parameters, the official has not yet been announced. But Wei auto insiders say, this super car aim is beyond all gasoline vehicles in the market in terms of performance.

It is reported that Wei to the pure electric supercar will be released on November 21 in London, the first batch of 6 cars, opponents locked the Ferrari LaFerrari.

First manned electric helicopter range of 55 km of hauling 270 kg

United States electric Brammo motorcycles brand, recently made an electric helicopter. Them on the basis of a passive Robinson R44 helicopter, by installing the battery and motor, realization of helicopter powered by electric.

After the refit, the helicopter flew out of the truck in a test of 272 kg range of 55 km, air time up to 20 minutes. However, fuel version of the Robinson R44 's largest range of 640 km, maximum loading capacity of 450 kg. Aviation, pure electric power now, still a little funny.

But Brammo is not discouraged, their ultimate goal is to achieve the 150 minutes of air time, which includes 30 minutes of standby power. Moreover, the Brammo also announced that strive to be released next year called EPASROD electric helicopter prototype. The track really horse King Ferrari FXX k

Chinese made cars if production of 300 000 cars chips cost around 6000 New think

On August 25 at the Shanghai New International Expo Center, CEO of Chinese solar-powered car Division Gao Weimin on the MMC for prospectively Hina's solar car project road show, the 20-minute speech, he spoke for 30 minutes. Much of which is in interpreting the Chinese feasibility of solar thin-film chips used in automobiles.

Gao Weimin said after the speech ended, Han had to car makers in the early promotion of solar cells, "and they (automakers) said there is hope for solar cells, you use, we provide chip, none successful. "To this end, this becomes an introduction of the Chinese-made car. Han could build cars through auto industry believes that thin-film solar chips to power the car, let it on the road.

Early last month, Han released four solar car: Hanergy Solar o, Hanergy Solar l, Hanergy Hanergy Solar and Solar a r. Then a question.

In fact, the Chinese can "build a dream" from the date of birth had been questioned. Partly because most people have never seen a car powered by solar energy, how many will doubt the feasibility of the commercial production; the other is last May, Chinese share prices were halved, billions in market capitalization, has shaken the faith of many people. Moschino iPhone 5

Gao Weimin also clearly perception of Chinese solar car challenge, after the speech, he told the media: many car industry is not too optimistic about solar energy, they don't know much about solar cells to one of today's State. Each solar, he thought (conversion rate) or 6% to 7%. About solar chips in cars, they are not convinced.

In the past few years, Chinese overseas four thin-film solar companies through mergers and acquisitions: Alta Devices, and Solibro, and MiaSol e and Global Solar Energy to accumulate thin film technology, and technology integration energy conversion rate from the industry's level of 15% to 18% to 31.6%. Is to a large extent, Chinese can build confidence that stems from confidence in thin film chip technology.

According to Han's plan, conversion rate of GaAs thin film solar cell technology will continue to improve, by 2020, conversion of 38% and 42%. Moschino iPhone Cases

"Photovoltaic technology and vehicle technology are two totally different subjects, do people just want to do cars, photovoltaic people only think of film power, so Chinese solar-powered car will be combining these two is no easy task. "Gao Weimin has on a number of occasions that this view. He believes that solar cars are ultimately two interdisciplinary cars and solar energy innovation, very valuable. This is also in the SAIC and Beijing Automotive Research Institute, respectively President of the Gao Weimin joined Han can be one of the reasons.

In early July this year's event, Chinese cooperation with the Foton program is to use solar energy to provide the electricity required to meet the bus air conditioning. Now, before this is the Chinese build a solar car to the transition programme.

Chinese Senior Vice President Zhang bin can tell us, "chip, we can turn to a transition programme, does not mean that all of a sudden. Such as basic auxiliary power supply, and then slowly transition to full solar car programme. This is path problem. 」

Even though the volume production of solar cars also need to address some technical bottlenecks, but Zhang bin's statement also showed that Chinese could launch the first solar car, most likely in the embedded solar cells on the basis of lithium-ion batteries, which work with solar energy and battery, increase the mileage and reduce battery weight of pure electric vehicles, while meeting weight requirements of body. Gao Weimin said Han was contacted some auto makers, which tries to be sold to the latter.

Han can tend to sell solution is still built cars, Gao Weimin said both have the will, but prefer the latter. His nets from Lei Feng (search for "Lei feng's network", public interest) explained that through their own car, you can feel how the chips for the automotive industry to develop. This is because the level of solar cells with the original chips can vary in technology, equipment and raw materials. Automotive research and development of chip, is the ongoing work of the Chinese.

At this stage, Chinese solar-powered car that can also have a lot of work needs to be combed. Gao Weimin said the current path of the Chinese-made cars are still in progress:

Han will in accordance with the relevant provisions, establish an automotive company, apply for qualification to obtain the relevant Department. He said a wide range of cooperation in the future, such as acquisitions, set up a joint venture with a third party company on behalf of workers, and so on. Gao Weimin said at the current pace, Han's first solar-powered car will be available within three years. In terms of costs, he said if we can produce 300,000 vehicles, when the chip costs around 6000.

According to the Chinese planning, solar car there deliberately to charge fixed charge facilities, in conditions of good lighting conditions, parking charge in the Sun. In addition, fully solar-powered car equipped with conventional lithium batteries for energy storage, in wet weather or long distance travel needs, allows you to charge fixed charge facilities, maximum range of 350 km.

Similar to the Han dynasty and the early of BYD. 13 years ago, BYD has a battery technology and related patents, but there was no car manufacturer who is willing to focus on pure electric vehicles, BYD has to make cars. After more than 10 years of accumulation, the technology got started on a battery car manufacturers to this day. For Chinese with thin-film solar technology, this vehicle way too long. But the bigger challenge is that car needs a lot of money.

Deep learning under four big beast

Now more and more people want to talk to your own virtual personal assistant, let Siri/Alexa/Rokid help you only take your pencil to complete the probe, ticket booking, set the alarm clock to the business, meeting also can remind you to take the medicine, so one does not need to pay warm padded jacket can not liked about it? Virtual Assistants are closer to the reality of personal assistants, and behind it is the depth of learning technology. Other than the virtual assistant, advanced learning technology will also be the future of computer vision, automatic driving core technology, speech recognition, and other fields. Depth study and practice the four key elements: computation, algorithms, data, and application scenarios, as guardians of the four animals to ensure that the depth of learning and practice, are indispensable.

Depth is not less than two hidden-layer neural network to nonlinear input transformation or learning technology by building deep neural network analysis of the activities carried out. Deep neural network consists of one input, a number of hidden layers, and an output layer. Each layer has a number of neurons and connections between neurons the weights. Each neuron simulation of biological neurons and connections between nodes simulate the connections between nerve cells. Summed up like this:

This flow chart is a special property of depth (depth): from an input to an output of the length of the longest path. Deep learning is not a new concept, but in 2006 by Hinton, who led a wave of outbreak. However in recent years, although a lot of people are talking about deep learning, but which is the practical application of this technology? Starting mature companies rely on deep learning what elements are needed? Here is our opinion.

| Computing power

First, the depth of complex neural network, data, and computing capacity. Depth of neurons in the neural network, number of connections between neurons are also pretty amazing. From a mathematical point of view, each neuron to include mathematical calculations (such as the Sigmoid, ReLU or Softmax function), the need to estimate the amount of parameters also have a great. Speech and image recognition application, neuron, tens of thousands of parameters of tens of millions of, model complexity leads to calculation. So computing power is the Foundation of the application deep learning.

Not only so, calculation capacity also is promoted depth learning of weapon, calculation capacity more strong, also time within accumulated of experience on more more, and Diego generation speed also more fast, Baidu Chief Scientist Wu Enda Dr think depth learning of frontier are transfer to high performance calculation (HPC), this is he currently in Baidu of work gravity one of, Wu Dr think depth learning Shang of many success thanks Yu active to pursuit available of calculation capacity, 2011 Jeff Dean (Google Tensorflow one of the designers of the second generation of artificial intelligence learning system) founded and led Google depth study group, using Google's cloud extending deep learning; it allowed deep learning to push the industrial sector. In 2013, Dr Coates, who established the first deep learning of HPC systems, scalability, improved the 1-2 of magnitude, caused a revolutionary advance in deep learning--computing power of that deep learning support and role are irreplaceable.

Currently this aspects technology in leading status of also is like Baidu, and Google such of large Internet company, certainly also some like horizon robot such of start-up company in the field quite achievements, by Baidu depth learning Institute head Yu Kai Dr founded of horizon robot company design of depth neural network chip compared traditional of CPU chip can support depth neural network in the image, and voice, and text, and control, aspects of task and not to do all things, such than in CPU Shang with software to efficient, 2-3 increase in orders of magnitude.

| Algorithm MCM case

In calculation capacity became increasingly cheap of today, depth learning tries to established big have more also complex have more of neural network, we can put algorithm understanding for depth learning of neural network or calculation thinking, this neural network more complex, capture to of signal on more precise, currently compared common of algorithm including depth faith network (Deep Belief Networks), and volume product neural network (ConvolutionalNeural Networks), and Restricted Boltzmann machine (Restricted BoltzmannMachine) and stacked automatically encoder (Stacked Auto-encoders), represented by the advanced Convolutional neural network learning method was by far the most used and most effective.

But currently problem is everyone put focused degrees put in has data and operation, because neural network itself differences not is big, and neural network of core algorithm upgrade up too difficult, still faced with like local optimal problem, and cost function and whole neural network system of design, problem, but this also to many venture company to new of thought, why opposite, avoid that contains with took of "bridge", if can will algorithm optimization, future is limitless of.

| Data

Deep learning is fast becoming a hot topic in the field of advanced data analysis, and the absolute amount of data is to facilitate deep learning tools and technological development one of the key factors. DanielMcDuff Affectiva, Chief Scientist and Research Director, emerging after the company has accumulated enough data, technology can play a better role. For those who the application deep learning and development needs a lot of time training, and improve not only in product promotion need more user data in real time, continuous iteration, update.

Study in depth, China still has a good chance in the competition, availability of data over the Internet, as well as low-cost labour, China will bring vast amounts of data and very low cost of data tagging. But the problem is that large amounts of data for domestic market are Internet giants such as BAT control, start-ups are very hard to get the data to improve, update, deep learning of neural networks, especially after the product launch, also could face malicious marginalization of a large company, get data more difficult, is not said to be surviving in the crevice about it. MCM iPhone 6 case

| Application scenarios

Depth learning technology currently application of scene not more, most general is most success of field is voice recognition and image processing this two application scene has, zhiqian mentioned of three big God beast--calculation capacity, and algorithm and data belongs to development end, application scene is belongs to consumption end level, with future depth learning technology of constantly development and user of needs upgrade, depth learning of application scene will increasingly more, like many intelligent phone built-in of people face recognition function to on photos for classification, has can reached quite of accurate rate ; PayPal financial tools, such as a face recognition is most likely to increase security ... ... Depth of the future study is not limited to speech recognition and image recognition in both areas, there are many more possibilities. For those startups, with Google, Facebook, Amazon, BAT has over ten years of precipitation data, such as large companies compete in this mature market, rather than to develop a piece of their own little world.

Now depth learning of hot degree not weak Yu any other of field, Internet giant are are in trying to points this block cake, actually wants to do depth learning calculation capacity, and algorithm, and data, and application scene this four Dharma God beast integral, and BAT, giant in these aspects are accounted for do resources Shang of advantage, for start-up company for hard four points both, especially data aspects, so using itself of compared advantage caught which one points for innovation, regardless of is calculation capacity, and algorithm also is application scene Shang, As long as innovation place, can help you seize the initiative in the market.

Dry goods speech recognition framework progress depth sequence Convolutional

Review: by far the best voice-recognition system uses a two-way short-term memory network (LSTM,LongShort Term Memory), however, this system of training, decoding complexity Shi Yangao problem, especially in the industrial sector in real-time recognition system it is difficult to apply. HKUST news fly in this year puts forward a new sequence of speech recognition framework--depth Convolutional neural networks (DFCNN,Deep Fully Convolutional NeuralNetwork), better suited to industrial applications. This article is on the HKUST to fly using DFCNN detailed interpretation applied to phonetic transliteration technology, also contains a phonetic transliteration of the colloquial and discourse-level language-model processing, noise and far-field recognition and text-processing real-time error correction and text processing technology analysis.

Application of artificial intelligence, voice recognition to make significant progress this year, both in English, Chinese or other languages, speech recognition accuracy rates on the rise of the machines. Speech dictation most rapid technology development, has been widely in voice input and voice search, voice Assistant applied product and maturity. However, another dimension of voice applications that phonetic transliteration, at present there are still some difficulties, because users in the process of recording file and the recording is not expected to be used for speech recognition, compared with voice dictation, phonetic transliteration will face speaking style, with a strong accent, the quality of the recording and many other challenges.

Phonetic transliteration of scenarios including, talking to reporters, TV shows, classes and conferences, including anyone in the everyday working life of any audio file. Phonetic transliteration of markets and imagine space is a huge, imagine if mankind can conquer the voice transcription, TV can automatically vivid titles, formal meetings can be formed automatically applies, journalists interview recording can be automated draft... ... In a person's life says to Zi much more than we wrote, we said if there is a software that can record all the words and efficient management, this world would be so incredible.

Acoustic modeling technology based on DFCNN

Acoustic modeling for speech recognition is mainly used for modeling speech signal and the relationship between phoneme, flew on December 21 last year at HKUST proposed feed-forward sequence memory (FSMN, Feed-forward Sequential Memory Network) as an acoustic modeling framework, again this year, launched a new speech recognition framework, namely the depth sequence Convolutional neural networks (DFCNN,Deep Fully Convolutional NeuralNetwork)。

By far the best voice-recognition system uses a two-way short-term memory network (LSTM,LongShort Term Memory), this network can model a long-term relationship between voice, so as to improve recognition accuracy. Bidirectional LSTM networks training, decoding complexity Shi Yangao problems exist, especially in the industrial sector in real-time recognition system it is difficult to apply. HKUST flew deep sequence Convolutional neural networks to overcome the shortcomings of bidirectional LSTM.

CNN is used for speech recognition system as early as 2012, but no major breakthroughs. Main reason is that it uses fixed-length frames mosaic as input, speech context information isn't long enough to see another defect to CNN as a feature Extractor, convolution layers are rarely used, and limited skills. Victorias Secret case for iPad Mini Victorias Secret iPad

To solve these problems, DFCNN uses a lot of convolution direct modeling the entire speech. First, input DFCNN spectrogram directly as input, compared to other traditional voice features speech recognition as input has a natural advantage over the framework. Secondly, in the model structure, using image recognition network configuration, each using small convolution kernel convolution, and ponds and layer after layer of multiple convolution by accumulating a lot of convolution pool layer, so that you can see a very long history and information in the future. These two points ensures excellent long-term relationship between voice and expression of DFCNN, RNN networks than in more great robustness, as well as online decoding of short delay, which can be used in industrial systems.

Spoken language and discourse-level language-model processing technologies

Speech recognition language models are mainly used for modeling of phoneme and corresponding relations between words. Because of human spoken language for natural language without organized, people in free conversation, often appeared to hesitate, read-back, modal and other complex languages, in text corpora are usually written in the form, the gap between these two language modeling for spoken language faced extreme challenges.

HKUST news fly learn from speech recognition to work with noise problems using training ideas, on the basis of written language automatically bring back reading, inversion, modal, colloquially "noise" phenomenon, which can automatically generate mass speech, resolve the mismatch between spoken language and written language. First, collect the part on oral and written text corpus and, secondly, using written language modeling based on Encoder-Decoder neural network framework and the correspondence between the spoken text, enabling automatic generation of spoken text.

In addition, the context information can greatly help people's understanding of language, same is true for machine transcription. Thus, flew on December 21 last year at HKUST programmes chapter-level language model is proposed, which according to the decoding of speech recognition results automatically for critical information extraction, data search and processing in real time, decode results and search form a special voice of corpus of language models to further improve the accuracy of speech transcription.

(Chapter-level language model flow chart)

And far-field noise recognition technology

Speech recognition using far-field pickup and noise are the two major technical problems. For example in Conference of scene Xia, if using recording pen for recording, away from recording pen more far talk people of voice that for far field with reverb voice, due to reverb will makes not synchronization of voice mutual overlay, brings has phonemes of make stack masking effect, to serious effect voice recognition effect; also, if recording environment in the exists background noise, voice spectrum will was pollution, its recognition effect also will sharply declined. HKUST news flew to solve this problem using the Dan Maike and the microphone array under two kinds of hardware noise reduction, reverb solution technology so far, voice transcription in noisy situations to achieve a practical threshold.

Dan Maike solutions of noise reduction, reverb

Loss of collected voice, mixed training and based on recurrent neural network method of reverberation noise reduction solutions combine. Namely, on the one hand clean noise added and mixed training with clean, thus improving the robustness of models for noisy speech (Editor's Note: transliteration of the Robust, that is robust and strong meaning);, use the depth based on recurrent neural network for noise reduction and reverberation, further increasing the noise, far-field voice recognition accuracy.

Microphone array solutions of noise reduction, reverb

Only noise in speech processing can be said to be a stopgap, how to solve the reverberation and noise from the source seems to be the crux of the matter. Faced with this challenge, and University researchers by recording equipment with multi-mic array on using microphone array noise and reverberation is performed. Specifically, when using multiple microphones capture multi-channel signals using Convolutional neural network beamformer, thus forming a pickup Steering in the direction of the target signal, and attenuation of reflected sound from the other. The above combination of Dan Maike reverberation noise reconciliation can be significantly improved with further noise, far-field voice recognition accuracy.

Text processing and real-time correction + text processing

Mentioned are only for voice processing technology, audio transcribed into text, but as noted above human spoken natural language with no organizational, even in the case of speech transcription accuracy is very high, transcribed from speech to text to read is still large problems, demonstrated the importance of the text. So-called text after text-spoken on clause, paragraph, and to deal with the fluency of the text content and even summaries of the content, in order to facilitate better reading and editing.

Post processing I: clauses with partition

Clauses, that is, clause divides the transcribed text notes, and add punctuation between clause; subparagraph a text into several semantic paragraph, every paragraph describes the different child theme.

By extracting contextual semantic features, combined with speech, to clauses and paragraphs divided; taking into account the annotated speech data is difficult to obtain, in practical use of ustc iflytek uses two levels of cascaded two-way short-term memory network model technology, so as to better address the clauses with partition problems.

Post processing II: smooth

Smooth, also known as flow testing, which eliminate the transfer results in pauses and tones of words, repeated words, make smooth text easier to read.

HKUST flies by using the generalization characteristics combined with the bi-directional short-term memory network modeling, making smooth accurate rate reached a practical stage.

Storm fengxin why do you need virtual reality

From guokr.com

Text/storm CEO fengxin

If you want to use a vernacular to illustrate what is virtual reality, and that is as true of false.

Don't worry said, "I don't need it!"

May I ask why do you watch movies and novels, gaming, daydreaming?

Is in fact trying to experience living in a different dream feeling. Because in real life, boring and limited and mediocre, dream, then to colorful, free and great.

But did you ever meet? Where is the difference? Successive advances of the books, movies, games, 3D plus online, someone is there to accompany you, there would still be a lot of "distance". A high-risk brain repair also can not cross the distance! (I really think horror films and XX more cattle, because they are diaofa other intrinsic enzymes in your body and nerves, greatly strengthening the brain up! Create a more authentic experience. ）

As far as I know, eliminating the sense of distance in a fictional world, though they may really have four different methods:

1, dreaming. Dream real scary sometimes, but the disadvantage is also evident, is not controlled. Inception of the auditor should be dreaming of a future career.

2, meditation. So-called duck octupole, travel thousands of miles, but the disadvantage is the world's only master of only a few will.

3, for the first time to see the film. It is said that when the film was shown for the first time, a train, and half the people are scared. But this effect as the film gradually weakened, today you definitely won't.

4, Planetarium, sites such as Disneyland. This place is the cost too high, the other is monotonous. A dream is very boring, not to mention passive. Guerlain iPhone 5 Case

(In addition, the estimated drug abuse and mental illness should also be better, no experience and is not recommended. ）

Want to kill the sense of distance, you have to wonder how people perceive the world.

Buddha said, eyes, ears, nose, tongue, body (this is recognition of the world's six senses, idioms in six pure said "six"). But if you want to create a virtual world, but do not have to transfer all "six".

First to put "meaning" took off, that is straight attack command, must by medicine, or through neurons these future new weapons; I think put nasal tongue body also to first kill, with eye ear than up, they on you of sleep by insignificant, often in "no sleep by" State (6D, and 7D Theater of concept, through blast, and rain, and shaking Chair enhanced virtual of reality experience, but if not put eyes care good, other are is white hard); eye and ear is most important of, certainly with eye than up, ear actually is brothers level of.

Remember, the eye is the first.

So now I say white storm "mirror" this is how this virtual reality VR helmets do it from 0 to 1:

1, big enough to see into, close enough.

2, affect "brain up" to minimize the element of approximately equal to 0.

3, 360? You next turn around is like.

Well, this time you "fall in" virtual reality! And then get to the in-ear headphones, 5.1-channel technology. Big brother (eye), second brother (ear) 2 major senses are fooled. Guerlain iPhone 5 Case

0 to 1, your first experience, feels false to true. You don't believe in the mirror feel horror and XX films, games or the site to try. Anyway, I was seen by a horror film called up.

Virtual reality used basically in the public eye, is approximately equal to 0. Storm mirror experience do the 0 to 1, but virtual reality to 1 to 10, there is still a long way to go. You as close as possible to reality, interactive, when you caught with a real hand when the fake glasses in the mirror ... ... ; Nose, tongue, body, and especially for hands, body wear cover which I think may be able to rush to 4; If dry contact lenses plus ear bone vibration sound should be 6 minutes; if the retina, 8; Finally still have to rely on medicine on the nerve issue, major command, 10 minutes out!

Tips: one day, you're completely false as true, in a cold room in the Palace, facing the yellow face, but thought it was Lord Shiva to goddess ... ... You will doubt whether contrary to truth and reality? Still wait, under the brain repair, do we see is really? Dogs can see infrared light, snakes can see thermal image, one can see three colors, which is true?

Really, is always relative, we "thought".
