New theory explains Transformer efficiency tradeoffs

A new paper from arXiv explores the theoretical underpinnings of Transformer model efficiency, focusing on how to best allocate parameters like attention heads and dimensions across layers. The research provides mathematical analysis suggesting that early layers are crucial for information extraction and proposes strategies for parameter allocation to balance expressivity and efficiency. It also identifies and proves a 'saturation' behavior in softmax activations, indicating that increasing head dimensions can yield diminishing returns, especially with long sequences, and that later layers can be more parameter-efficient.
