DEEPMIND'S NEW AI GENERATES SOUNDTRACKS AND DIALOGUE FOR VIDEOS

DeepMind is developing an AI technology called V2A to generate synchronized soundtracks for videos. It uses diffusion models trained on audio, dialogue transcripts, and video clips to create music, sound effects, and dialogue.

GIANT CHIPS GIVE SUPERCOMPUTERS A RUN FOR THEIR MONEY

Cerebras, a California-based company, has demonstrated that its second-generation wafer-scale engine is significantly faster than the world's faster supercomputer in molecular dynamics calculations. It can also perform sparse large language model inference at one-third of the energy cost of a full model without losing any accuracy. Both achievements are possible due to the interconnects and fast memory access enabled by Cerebras' hardware. Cerebras is looking to extend the applications of its wafer-scale engine to a larger class of problems, including molecular dynamics simulations of biological processes and simulations of airflow around vehicles.

LOGICAL REASONING IN LANGUAGE MODELS

Chain of Preference Optimization (CPO) is a method that improves the logical reasoning abilities of large language models (LLMs). By fine-tuning LLMs using search trees from the Tree-of-Thought (ToT) method, CPO aligns the reasoning steps of Chain-of-Thought (CoT) decoding with ToT's optimal paths.
