Researchers have developed a new technique called Token-Selective Attention (TSA) for transformer models that allows them to dynamically adjust the computation depth for each token. This method uses a lightweight, learned gate to decide whether to skip residual updates between transformer blocks, making the process end-to-end differentiable with minimal parameter overhead. TSA demonstrated significant savings in token-layer operations, reducing them by 14-23% on character-level language modeling tasks with less than 0.5% quality loss, and showed improved performance compared to early exit methods at similar efficiency levels.
