Technology Early: 2017 is destined to be an extraordinary year in the history of artificial intelligence

1, the world's strongest AI startup company TOP100 list 7 Chinese companies on the list

Recently, CB Insights released the second AI 100, the world's strongest AI startup company list. According to the media, more than 2,000 companies were nominated and applied for the AI ​​100, and the selection rate was less than 5%, covering 25 industry applications in the AI ​​field, such as the Internet of Things, health care, automobile driving, financial technology, and cybersecurity.

The 100 companies on the list received 117 billion U.S. dollars in equity financing through 367 transactions. Some startups focused on specific use cases. For example, AiCure specializes in drug compliance, Gong analyzes the sales team calls, and Zest Finance covers credit.

In the AI ​​100, eight companies provide enterprises with the development of artificial intelligence applications. Currently, this market is dominated by Amazon.

There are 7 Chinese companies selected this time: Contempt technology, go out to ask, today's headlines, fluent in English, excellent choice, Shang Tang technology, the Cambrian, which go out to ask questions and excellent selection is the second time .

Comments: The artificial intelligence (AI) concept has become the strongest market in the current market. However, how to more fully demonstrate the superior strength of China's science and technology, we still need to continue our efforts to win more companies on the list.

2. Artificial intelligence commentary World Club Real Madrid match face recognition Ronaldo

On the early morning of the 17th, the 2017 FIFA Club Club ended in the UAE. This year's World Cup, a game of Real Madrid, after the game to give an explanation of artificial intelligence, widely circulated on the Internet. In this video, the machine automatically recognizes information such as team formation and player running trajectory.

It is understood that this video was performed by the Real Madrid fans of the Ali cloud engineering team. "FIFA Club Club is a partner of Alibaba Cloud. Real Madrid made its debut in the early morning of the 14th. Engineers are also Real Madrid fans. They used the highlight video to make an experimental attempt."

For the concrete realization of how to realize the trajectory of players and footballs by machines, the relevant engineers introduced that the players, the ball and the court must be identified on the court first, and a multi-channel neural network convolution model is designed for players and players. Precise positioning, combined with an efficient tracking algorithm, enables real-time tracking of the player's and ball's trajectory on the field.

Comments: 2017 is destined to be an extraordinary year in the history of artificial intelligence, we guess what will play next year? Wan Weijun really looks forward to it.

3, Tencent Jingdong premium 55% stake in the only product

On the 18th, the e-commerce platform Vipshop announced that it had signed a joint investment agreement with Tencent and Jingdong Group. According to the agreement, Tencent and JD.com will respectively purchase US$604 million and US$259 million worth of VIPA Class A common stock. The purchase price is US$65.4 per Class A common stock, which is equivalent to US$13.08 per AXIS ADS.

The transaction will be completed in the near future, when Tencent and Jingdong will hold 7% and 5.5% of the shares of VIP, including the previously owned shares of VIP. Jingdong previously held 2.5% of Vipshop shares.

Comments: E-Commerce becomes more and more obvious in the fight for both strengths. Jingdong has also made various breakthroughs on the way to vertical e-commerce to achieve full competition with Ali. Under such circumstances, how many cakes are left for other vertical e-commerce platforms?

4, face recognition to unlock the phone has a potential risk, the photo can unlock

“A lot of mobile phone manufacturers dare to use face detection technology without joining the body detection technology. This is incredible in our view.” The relevant person in charge of the Chinese Academy of Sciences’ cloud-cloud technology expressed its incomprehensibility to the domestic mobile phone face recognition technology.

In early December, the “IT Times” reporter selected the vivo X20 and OPPO R11s, which are currently the most popular on the market, for face unlock testing. The tested version is divided into the factory version and the latest upgrade version.

In the “factory version” test, the reporter used a 1:1-size color print photo of a human face. Under dark lighting, after several angle adjustments, the vivo X20 mistakenly believed that “face” completed the first portrait entry. Use the same photo to unlock it successfully. The OPPO R11s failed to unlock the photos, but the intermediate system had a few “pauses” that caused the real human faces to fail to recognize them.

For the risk of face recognition, both the vivo X20 and OPPO R11s have posted an eye-catching "disclaimer" in the system - "The phone may be unlocked by people or objects whose appearance and shape are similar to yours" "Facial recognition security "Under fingerprints, pattern codes, numeric codes, and custom alphanumeric codes" "Under low light, strong light, and backlight conditions, the unlocking success rate of facial recognition will be reduced."... However, it is recognized in face recognition technology. There are vulnerabilities that are difficult to solve, but in the current feature set of these two phones, the face lock can be used for important functions such as "application encryption" and "file encryption" in addition to the unlocking of screens.

Comments: so many bugs and traps, anyway, Wanwei Jun is afraid to use, I heard there are new technologies, but many mobile phone manufacturers are not "cold", the fundamental reason is "slow" and "expensive", can be seen far When it is mature.

Vibration Motor

Vibration Motor:

Is mainly used for adult health care products and toys micro vibration motor is a Dc Motor, the motor shaft with an eccentric wheel, when the motor rotation, eccentric circle particle is not turn the heart of the motor, make motor is constantly out of balance state, caused by inertial effect.


Characteristics: small volume, strong vibration;


Features: small size, fast speed, stable performance, low price, can use battery drive,Can change the different materials of the pendulum head
Vibration Motor Vibration Motor
Method of use: the best stable in horizontal plane, installed on the dc vibration motor output shaft parts, cannot use a hammer to knock, knock prone to press into the dc vibration motor drive, may cause damage to internal components, and cannot be used in the case of blocked.

vibration motor

Operating temperature range:

vibration motor should be used at a temperature of -10~60℃.

The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.

If a vibration motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.


Storage temperature range:

vibration motor should be stored ta a temperature of -15~65℃.

In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.


Service life:

The longevity of vibration motor is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.


●Use with a load that exceeds the rated torque

●Frequent starting

●Momentary reversals of turning direction

●Impact loads
