Honor Magic V3 debuts AI defocus eye protection technology: effectively alleviates the development of myopia
Jul 18, 2024 am 09:27 AM
According to news on July 12, the Honor Magic V3 series was officially released today, equipped with the new Honor Vision Soothing Oasis eye protection screen. While the screen itself has high specifications and high quality, it also pioneered the introduction of AI active eye protection technology. It is reported that the traditional way to alleviate myopia is "myopia glasses". The power of myopia glasses is evenly distributed to ensure that the central area of sight is imaged on the retina, but the peripheral area is imaged behind the retina. The retina senses that the image is behind, promoting the eye axis direction. grow later, thereby deepening the degree. At present, one of the main ways to alleviate the development of myopia is the "defocus lens". The central area has a normal power, and the peripheral area is adjusted through optical design partitions, so that the image in the peripheral area falls in front of the retina.

New stacking process! Xiaomi MIX Fold 4 is equipped with Jinshajiang 'three-dimensional special-shaped' battery for the first time
Jul 20, 2024 am 03:20 AM
According to news on July 19, Xiaomi MIX Fold 4, the first flagship folding new phone, was officially released tonight and is equipped with a "three-dimensional special-shaped battery" for the first time. According to reports, Xiaomi MIX Fold4 has achieved a major breakthrough in battery technology and designed an innovative "three-dimensional special-shaped battery" specifically for folding screens. Traditional folding screen devices mostly use conventional square batteries, which have low space utilization efficiency. In order to solve this problem, Xiaomi did not use the common winding battery cells, but developed a new lamination process to create a new form of battery, which greatly improved the space utilization. Battery Technology Innovation In order to accurately alternately stack positive and negative electrode sheets and ensure the safe embedding of lithium ions, Xiaomi has developed a new ultrasonic welding machine and lamination machine to improve welding and cutting accuracy.
Xiaomi's 100-yuan phone Redmi 14C design specifications revealed, will be released on August 31

Tsinghua Optics AI appears in Nature! Physical neural network, backpropagation is no longer needed
Aug 10, 2024 pm 10:15 PM
Using light to train neural networks, Tsinghua University results were recently published in Nature! What should I do if I cannot apply the backpropagation algorithm? They proposed a Fully Forward Mode (FFM) training method that directly performs the training process in the physical optical system, overcoming the limitations of traditional digital computer simulations. To put it simply, it used to be necessary to model the physical system in detail and then simulate these models on a computer to train the network. The FFM method eliminates the modeling process and allows the system to directly use experimental data for learning and optimization. This also means that training no longer needs to check each layer from back to front (backpropagation), but can directly update the parameters of the network from front to back. To use an analogy, like a puzzle, backpropagation
