Differentiable Optimization of Generalized Nondecomposable Functions using Linear Programs

no code implementations NeurIPS 2021 Zihang Meng, Lopamudra Mukherjee, Vikas Singh, Sathya N. Ravi

We propose a framework which makes it feasible to directly train deep neural networks with respect to popular families of task-specific non-decomposable per- formance measures such as AUC, multi-class AUC, F -measure and others, as well as models such as non-negative matrix factorization.

A Biresolution Spectral Framework for Product Quantization

no code implementations CVPR 2018 Lopamudra Mukherjee, Sathya N. Ravi, Jiming Peng, Vikas Singh

In this paper, we study the quantization problem in the setting where subspaces are orthogonal and show that this problem is intricately related to a specific type of spectral decomposition of the data.

Filter Flow Made Practical: Massively Parallel and Lock-Free

1 code implementation CVPR 2017 Sathya N. Ravi, Yunyang Xiong, Lopamudra Mukherjee, Vikas Singh

This paper is inspired by a relatively recent work of Seitz and Baker which introduced the so-called Filter Flow model.

An NMF Perspective on Binary Hashing

no code implementations ICCV 2015 Lopamudra Mukherjee, Sathya N. Ravi, Vamsi K. Ithapu, Tyler Holmes, Vikas Singh

In this paper, we first derive an Augmented Lagrangian approach to optimize the standard binary Hashing objective (i. e., maintain fidelity with a given distance matrix).
