Introducing an Efficient Machine Learning Method for Large Language Models (LLMs)
Memory is crucial for intelligence, allowing us to recall past experiences and apply them to current situations. However, traditional Transformer models and Large Language Models (LLMs) face limitations in context-dependent memory due to their attention mechanisms. These mechanisms lead to high memory consumption and computation time.
Practical Solution: Compressive Memory Systems
Compressive memory systems offer a practical solution by efficiently managing lengthy sequences with constant storage and computation costs. Unlike traditional attention mechanisms, they maintain a fixed number of parameters for storing and retrieving information, reducing memory expansion with input sequence length.
Google’s Unique Solution: Infini-attention
Google’s researchers have proposed Infini-attention, a unique attention mechanism that combines long-term linear attention and masked local attention into a single Transformer block. This approach includes compressive memory in the attention process, effectively managing memory while processing lengthy sequences.
Value and Applications
The Infini-attention method has shown effectiveness in tasks such as book summarizing and language modeling with input sequences of up to 1 million tokens. It enables minimal bounded memory parameters and fast streaming inference for real-time analysis of sequential input.
Key Contributions
The team presents Infini-attention as a useful method that represents contextual dependencies over short and long distances. It can be easily incorporated into current Transformer structures, enabling continuous pre-training and long-context adaptation.
Conclusion
This research is a significant advancement for Large Language Models, enabling efficient handling of very long inputs in terms of computation and memory utilization.
