Breakthrough in ByteDance AVG encoding technology: shrink video by 13%
According to the news on March 1st, according to the official website of the Joint Video Expert Group JVET, ByteDance AVG (Advanced Video Team) initiated a video compression technical proposal in February this year, which can optimize compression quality while saving at least 13% Storage and bandwidth. For example, a 180-minute H.266/VVC standard high-definition video (1080P resolution) requires about 3GB of data volume, and only 2.6GB after applying the new technology.
The new algorithm proposed by AVG this time by Byte Beat aims to build a filter (DAM) that reduces video compression distortion through deep learning technology. The backbone is a deep convolutional network based on stacking residual units, supplemented by adaptive model selection to maximize Adapt to natural videos with complex characteristics.

Hinton independent release 44 on the text: "one-man show" GLOM, expressing neural network
On February 25, a 44-page paper signed only by Turing Award winner Hinton was uploaded to the pre-printed paper platform arXiv, which caused a shock in the artificial intelligence community. This is another attempt at deep learning model architecture after Hinton and his collaborators’ capsule network CapsNet was made public in 2017.
Hinton wrote in the abstract of the paper: "This paper does not describe a system that is already in operation. It only describes a single idea about representation, allowing the progress made by several different groups to be combined into one called GLOM's hypothetical system. These advancements include Transformer, neural field, contrast representation learning, model distillation, and capsule. GLOM answers a question: How does a neural network with a fixed architecture parse an image into parts- The overall hierarchical structure, and the hierarchical structure of each image is different?
"If we want a neural network to understand images like humans, we need to find out how the neural network represents the part-the overall hierarchy." Geoffrey, vice president of Google, engineering research expert, chief scientific adviser of the Vector Institute, Emeritus professor emeritus at the University of Toronto Hinton said.

The PS5 host is cracked? Can also mine, with computing power far surpassing high-end graphics cards? Netizen: Onion News
Previously, the use of PS5 for mining was restricted by the system, and various mining programs could not be executed. Recently, some netizens broke the news that the PS5 was cracked, and also released a screenshot of the interface of the PS5 host for mining ETH.
From the mining interface, the mining performance of the PS5 host is quite powerful, with a computing power of 99.76MH/s and a power consumption of only about 211 W. The energy efficiency ratio is still very good.
Unfortunately, it was verified by netizens later that this was Onion News. Scanning the QR code shown in the picture shows: "Entertainment only, and there is no such software."

Bad weather in the United States caused the father of Linux’s home to be out of power and network for six days: kernel update postponed
Recently, the United States has been hit by severe weather, and some states and cities have experienced blackouts. Linus Torvalds, the father of Linux who lives in Portland, Oregon, also encountered the above problem. He reluctantly stated in the latest log that he had experienced a power outage for up to six days, so the merger of Linux kernel 5.12 would take an extra week. .
Linus also pointed out that this version of the kernel has only collected about 10,000 submissions, which is much less than the usual 12,000 to 13,000.
It is reported that the Clang Link-Time optimization is added in Linux kernel 5.12 to improve the performance of the compiler. At the same time, it supports Intel's eASIC NX5 chip (designed to be an alternative to FPGA in the field of edge and cloud computing), and supports the Snapdragon 888 5G SoC. At the same time, the old OPROFILE support and some SoC driver files that no longer make sense have been removed.
