Efficient Transformer Models with Infinite Context
Google introduces a method to scale transformer models to infinitely long inputs using a compressive memory mechanism. By incorporating compressive memory into the attention mechanism, they enable both local attention over memory and long-term linear attention. Compared to alternative methods, they show improved performance in tasks like book summarization with 1 billion and 8 billion parameter models.
Dynamic Allocation of Compute in Language Models
DeepMind presents mixture of depths, a concept that allows language models to dynamically choose which layers to skip, optimizing compute usage. This method, similar to mixture of experts, helps achieve the same loss with less compute, demonstrating cost efficiency and performance improvements when combined with other techniques like mixture of experts.
Advancements in Neural Architecture
Vanilla transformers combining architecture knowledge with current segment input, leading to better predictions and memory structures in AI models. The concept echoes state-space models' explicit memory updates.
On-Device Language Model Innovations
Octopus V2 introduces a method for on-device language models with two billion parameters, outperforming GPT-4 with reduced context size by 95%. It utilizes tokenized function calls for improved performance and efficiency across various edge devices.
Scaling Properties in Latent Diffusion Models
Research explores scaling effects in image generation using latent diffusion models, revealing that smaller models might produce better image quality at the same computational cost compared to larger models. The paper highlights efficiency improvements and potential implications for distilling larger models into smaller ones.
Policy Implications for Responsible AI Development
Washington state judge blocks the use of AI-enhanced videos as evidence due to concerns about accuracy and reliability, possibly setting a precedent for handling AI-enhanced media. The US government engages with tech companies to discuss AI electricity demands, considering approaches like using nuclear fusion to meet AI data center energy needs.
Initiative for Responsible AI Music Practices
Renowned artists sign an open letter advocating for responsible AI music practices to protect human artists' rights and fair compensation. The artists call for a halt in using AI technology that undermines human artistry and devalues artist's work.
Government Investments in AI Research and Regulation
Canada announces a $2.4 billion investment in AI-related innovations, focusing on access to computing capabilities and promoting AI adoption in various sectors. The bill C-227 aims at updating privacy laws and ensuring fair compensation for artists' work in the AI domain.
