As the brain of the huge system behind the double 11, the busy Ali cloud artificial intelligence ET also took the time to perform a magical magic.
On the evening of November 10th, "Tmall Double 11 Carnival Night" opened a giant screen at the Shenzhen Universiade Center. In addition to the stars of the world's half entertainment circle, there is also a mysterious guest with "super power" debut - Alibaba Cloud Artificial Intelligence ET. Under the witness of hundreds of millions of viewers around the world, ET has calculated the playing cards in the hands of five people and shocked the audience.
In the finale of the carnival night, ET showed a strong voice recognition and interaction ability when playing, and synchronized with the host Hua Shaoshen. As everyone knows, Hua Shao is known as "China's good tongue" with a speed of 400 words per minute. ET can actually translate Hua Shao's live slogan into text in real time and cast it on the TV screen to achieve extremely high accuracy. The fun part is that once an error occurs, ET will also make millisecond corrections in context.
Not only can you understand the problems of Hua Shao, but ET can also answer questions by imitating human voices through on-the-spot observation and thinking.
Hua Shao challenges: 5 out of 32 cards, can you guess what ET is? Then the host invites five live audiences to come to the stage, and then cuts the cards and then pulls out five. Can ET calculate the cards in their hands?
ET was slightly contemplative and made a small request. Please turn to the black-faced audience and turn around. After identifying the audience through machine vision, ET instantly calculated the answer: Plum A... Five of them were all in the middle! The magical performance of ET surprised the host. "It's too, no, yes, think, negotiate!"
In theory, the probability that all 32 cards should be guessed in 5 hands is one in 24 million. How is ET done?
"This is a classic magic, but this time it was performed by an artificial intelligence magician. 32 cards are arranged in De Bruijn sequence. After five people shuffle, the actual arrangement may be reduced to 32, and ET will turn to the audience ( Black card) is recorded as 1 red card audience recorded as 0. Further calculate the final unique arrangement from 32 possibilities," Alibaba Cloud AI scientist Min Min said, usually this magic is very test the magician's memory and calculation ability. For ET, these are not difficult problems.
The difficulty is that the ET needs high-accuracy, high-real-time video recognition capability in the whole process, and communicates with the host in human language. "Because the live broadcast environment is affected by the venue, lighting, and sound effects, speech recognition and video recognition will be greatly tested," said Yu Min.
It is understood that whether it is speech recognition or image recognition, the underlying layer relies on deep learning algorithms and large-scale computing capabilities. The training of a complex algorithm model often requires hundreds of billions of sample data, which puts high demands on the computing power behind it.
ET stands for Alibaba Cloud speech recognition, speech synthesis, natural language understanding, real-time image recognition, and machine learning. Behind it is the powerful computing power of Alibaba Cloud's operating system.
It is worth noting that this is not the first time ET has entered the stage. In the final of Hunan Satellite TV's "I am a singer" in April this year, ET successfully predicted Li Wei's victory at the live broadcast. In other areas, ET has begun to serve as a court clerk, super traffic police, film investment manager, and customer service.
A single-phase VFD, also known as a variable frequency drive, is a specialized electronic device used for precise control and regulation of single-phase motors. Unlike three-phase motors that are commonly used in industrial applications, single-phase motors are predominantly found in residential and small-scale applications.
The primary function of a single-phase VFD is to control the frequency and voltage supplied to the single-phase motor, thereby enabling accurate regulation of motor speed. By adjusting the frequency and voltage output, the VFD allows for smooth and precise control over the motor's rotational speed. This feature is particularly useful in applications where speed control is required, such as in residential HVAC systems, small-scale machinery, and household appliances.
Energy efficiency is a significant advantage offered by single-phase VFDs. By adjusting the motor speed to match the load requirements, the VFD reduces energy wastage and improves overall energy efficiency. When the motor operates at a lower speed during periods of low demand, energy consumption is significantly reduced, resulting in energy savings and lower operating costs.
Motor protection is another important aspect addressed by single-phase VFDs. They incorporate various protective features, including overload protection, short circuit detection, and thermal protection, which help safeguard the motor against damage due to excessive current, voltage fluctuations, or overheating. This ensures reliable motor operation, prolongs the motor's lifespan, and reduces the risk of unexpected failures.
Harmonic filtering is also a critical consideration in single-phase VFD applications. When single-phase VFDs operate, they can introduce harmonics into the power supply, which may cause issues such as voltage distortions and interference with other electrical equipment. To mitigate these problems, single-phase VFDs often incorporate harmonic filtering techniques to suppress harmonics and ensure a clean and stable power supply, maintaining power quality and preventing damage to connected equipment.
Control algorithms play a significant role in single-phase VFD operation. These algorithms allow for precise control and adjustment of motor speed, ensuring smooth acceleration, deceleration, and accurate speed regulation. Advanced control algorithms enable efficient motor operation and enhance overall system performance.
In summary, single-phase VFDs provide precise control and regulation of single-phase motors in residential and small-scale applications. With their energy efficiency, motor protection features, harmonic filtering capabilities, and advanced control algorithms, single-phase VFDs enhance motor performance, reduce energy consumption, and ensure reliable operation in various residential and small-scale applications.
