Fast LapSum: Exact Differentiable Top-k at Million Scale

Łukasz Struski, Joanna Wojciechowicz, Jakub Antczak +3

The top-k operation is a fundamental building block of modern sparse computation, enabling token routing, expert activation, memory selection, and attention pruning. Yet standard…

LaPrune: Controllable Differentiable Sparsity at Million Scale

Jakub Antczak, Joanna Wojciechowicz, Łukasz Struski +1

Top-k selection determines which components of a sparse model remain active. Hard selection blocks gradients, while continuous relaxations often couple mask hardness to the selec…
