Stabilizing Bi-Level Hyperparameter Optimization using Moreau-Yosida Regularization

1 code implementation27 Jul 2020 Sauptik Dhar, Unmesh Kurup, Mohak Shah

This research proposes to use the Moreau-Yosida envelope to stabilize the convergence behavior of bi-level Hyperparameter optimization solvers, and introduces the new algorithm called Moreau-Yosida regularized Hyperparameter Optimization (MY-HPO) algorithm.

Multiclass Learning from Contradictions

1 code implementation NeurIPS 2019 Sauptik Dhar, Vladimir Cherkassky, Mohak Shah

We introduce the notion of learning from contradictions, a. k. a Universum learning, for multiclass problems and propose a novel formulation for multiclass universum SVM (MU-SVM).

Improving Model Training by Periodic Sampling over Weight Distributions

no code implementations14 May 2019 Samarth Tripathi, Jiayi Liu, Unmesh Kurup, Mohak Shah, Sauptik Dhar

In this paper, we explore techniques centered around periodic sampling of model weights that provide convergence improvements on gradient update methods (vanilla \acs{SGD}, Momentum, Adam) for a variety of vision problems (classification, detection, segmentation).
