Inducing and Exploiting Activation Sparsity for Fast Inference on Deep Neural Networks

no code implementations ICML 2020 Mark Kurtz, Justin Kopinsky, Rati Gelashvili, Alexander Matveev, John Carr, Michael Goin, William Leiserson, Sage Moore, Nir Shavit, Dan Alistarh

In this paper, we present an in-depth analysis of methods for maximizing the sparsity of the activations in a trained neural network, and show that, when coupled with an efficient sparse-input convolution algorithm, we can leverage this sparsity for significant performance gains.

Sparse Expansion and Neuronal Disentanglement

no code implementations24 May 2024 Shashata Sawmya, Linghao Kong, Ilia Markov, Dan Alistarh, Nir Shavit

We show how to improve the inference efficiency of an LLM by expanding it into a mixture of sparse experts, where each expert is a copy of the original weights, one-shot pruned for a specific cluster of input values.
