Sparser, Better, Deeper, Stronger: Improving Static Sparse Training with Exact Orthogonal Initialization

ICML 2024poster

Static sparse training aims to train sparse models from scratch, achieving remarkable results in recent years. A key design choice is given by the sparse initialization, which determines the trainable sub-network through a binary mask. Existing methods mainly select such mask based on a predefined d…

Fantastic Weights and How to Find Them: Where to Prune in Dynamic Sparse Training

NeurIPS 2023poster

Dynamic Sparse Training (DST) is a rapidly evolving area of research that seeks to optimize the sparse initialization of a neural network by adapting its topology during training. It has been shown that under specific conditions, DST is able to outperform dense models. The key components of this fr…

Trust Your $\nabla$: Gradient-based Intervention Targeting for Causal Discovery

NeurIPS 2023poster

Inferring causal structure from data is a challenging task of fundamental importance in science. Often, observational data alone is not enough to uniquely identify a system’s causal structure. The use of interventional data can address this issue, however, acquiring these samples typically demands a…

Non-Gaussian Gaussian Processes for Few-Shot Regression

NeurIPS 2021poster

Gaussian Processes (GPs) have been widely used in machine learning to model distributions over functions, with applications including multi-modal regression, time-series prediction, and few-shot learning. GPs are particularly useful in the last application since they rely on Normal distributions and…
