New method optimizes Transformer FFN width using geometric analysis

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel method for optimizing the width of feed-forward networks (FFNs) within Transformer models, moving away from the standard constant width. By analyzing the geometric changes in token representations, they propose a layerwise allocation strategy that can reduce validation loss. This approach, tested on various pretrained language models, showed improvements over uniform width allocation, particularly in larger training runs. AI

IMPACT This research could lead to more efficient Transformer models by optimizing parameter allocation within FFNs.

    Geometry-Guided Layerwise FFN Width Allocation in Transformers

    arXiv:2608.02064v1 Announce Type: cross Abstract: Feed-forward networks (FFNs) account for a large fraction of Transformer parameters, yet their hidden width is usually constant across depth. We ask whether this capacity can instead be allocated from a forward-pass measurement of…
