At present, artificial intelligence has become familiar with tasks such as driving cars, translating languages ​​and recognizing faces. Next, the next goal in the field of artificial intelligence is to let AI have an intuitive sense of reaction to the outside world.
A new article on artificial intelligence published on the Computer Communications Association website found that artificial intelligence has evolved to begin to understand the world as people do without requiring humans to teach the world by carefully entering program data sets.
Yann LeCun, director of research on Facebook artificial intelligence, said that the company and other organizations' research provided artificial intelligence with more opportunities to cultivate human intuition, which is the key to perfecting artificial intelligence. In the next stage, artificial intelligence will be studied through observation, which is similar to that of a newborn baby.
LeCun said to the Association for Computing website: "At the moment, we don't know how to replicate the sense of intuition on the machine. This is a pity. Before we learn how to do this, we will not enter the next stage of artificial intelligence research."
At present, most artificial intelligence adopts the “supervised learning†mode, in which humans use a large number of carefully labeled data sets to train artificial intelligence, so that the latter can complete the recognition of faces or The task of language translation. Predictive learning is a new way of learning in the field of artificial intelligence. In this process, artificial intelligence is completely unsupervised by humans, so there is no need to have a marked data set. Instead, artificial intelligence begins to observe itself and uses its own observations to explore how the world works.
Someone commented on Facebook on the head of Industrial Intelligence Research Yann LeCun: How Tesla CEO Elon Musk has a better vision of the future of artificial intelligence . Musk made a sharp comment on this. In his comments on the personal Facebook news about predictive learning, he replied: "If the only thing you can do is to talk about it, then you can easily become a visionary. But if you are one Self-respecting scientists or engineers, then you can only say so much before you succeed in achieving the flaws you describe."
In essence, it is time for researchers to treat artificial intelligence as a baby and teach it in a way that teaches the baby to see what happens. Facebook's Artificial Intelligence Research Lab is working to make artificial intelligence use intuition vectors to connect the characteristics of things, thereby creating an image of an organic world in its impressions.
At the same time, research laboratories in other institutions have also established neural networks, all competing to create the most realistic images in the artificial intelligence impression. In this way, artificial intelligence can watch the pictures of some movies and predict what the next picture will look like. This is a perception that is closer to intuition, a feeling of the future, not the so-called limitations of artificial intelligence today.
LeCun believes that figuring out how to effectively use this learning method is the way to enter the next stage of artificial intelligence research.
A DC motor is any of a class of rotary electrical machines that converts direct current electrical energy into mechanical energy. The most common types rely on the forces produced by magnetic fields. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current flow in part of the motor.
DC motors were the first type widely used, since they could be powered from existing direct-current lighting power distribution systems. A DC motor's speed can be controlled over a wide range, using either a variable supply voltage or by changing the strength of current in its field windings. Small DC motors are used in tools, toys, and appliances. The universal motor can operate on direct current but is a lightweight motor used for portable power tools and appliances. Larger DC motors are used in propulsion of electric vehicles, elevator and hoists, or in drives for steel rolling mills.
Dc motor areas of application: smart home field, robotics, precision medical equipment industry, automotive drive field, electronic products and personal care equipment
Application of the product:
Features: high torque, low noise, small volume, light weight, easy to use, running constant speed, etc., can also be matched with various gearboxes to change the output speed and torque.
Features: small volume, fast speed, stable performance, low price, good speed regulation.
Method of use: the best stable in horizontal plane, installed on the dc motor output shaft parts, cannot use a hammer to knock, knock prone to press into the dc motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
DC 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 geared 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:
DC 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 DC 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.â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
