Imagine a large language model as a super-smart librarian who can understand and generate human language. LoKiFormer is a new way to design this librarian, making it more efficient and effective at understanding and generating language. It does this by focusing on local patterns and storing global knowledge in a special memory, allowing it to access and utilize information more efficiently.

LoKiFormer: A Novel Large Language Model Architecture
LoKiFormer is a novel large language model architecture that addresses two main limitations of existing models: self-attention's lack of explicit inductive bias for locality and mixture-of-experts' implicit coupling of knowledge storage with computational pathways. The proposed architecture introduces two dedicated modules: Local Fusion Attention (LFA) and Knowledge Memory Module (KMM).
Local Fusion Attention (LFA)
LFA incorporates a convolutional fusion to attention, explicitly capturing local patterns and allowing the attention to operate on more informative representations. This module enables the model to focus on local information and reduce redundant modeling of sequence-internal local information.
Knowledge Memory Module (KMM)
KMM introduces a parametric key-value memory that explicitly stores global knowledge in addressable slots, decoupling storage from computation and enabling direct knowledge retrieval. This module allows the model to access and utilize global knowledge more efficiently.
Experimental Results
Experimental results show that LoKiFormer converges 1.33x faster in pre-training than baseline models, underscoring its superiority over existing LLM architectures. The proposed architecture has the potential to improve the efficiency and effectiveness of large language models, which are crucial for various applications such as natural language processing and machine translation.
