LatentLLM: Activation-Aware Transform to Multi-Head Latent Attention

Modern foundation models such as large language models (LLMs) require a massive amount of computational and memory resources. We propose a new framework to convert such LLMs into a reduced-dimension latent structure. Our method extends a local activation-aware tensor decomposition to a global attention-aware joint tensor decomposition. Our framework can significantly improve the model accuracy over the existing model compression methods when reducing the latent dimension to realize computationally/memoryefficient LLMs. We show the benefit on several benchmark including multi-modal reasoning tasks.
