Improving Energy Conserving Descent for Machine Learning: Theory and Practice

1 code implementation1 Jun 2023 G. Bruno De Luca, Alice Gatti, Eva Silverstein

We develop the theory of Energy Conserving Descent (ECD) and introduce ECDSep, a gradient-based optimization algorithm able to tackle convex and non-convex optimization problems.

Graph Partitioning and Sparse Matrix Ordering using Reinforcement Learning and Graph Neural Networks

1 code implementation8 Apr 2021 Alice Gatti, Zhixiong Hu, Tess Smidt, Esmond G. Ng, Pieter Ghysels

The partitioning quality is compared with partitions obtained using METIS and SCOTCH, and the nested dissection ordering is evaluated in the sparse solver SuperLU.
