Data-Driven Low-Rank Neural Network Compression

no code implementations13 Jul 2021 Dimitris Papadimitriou, Swayambhoo Jain

Despite many modern applications of Deep Neural Networks (DNNs), the large number of parameters in the hidden layers makes them unattractive for deployment on devices with storage capacity constraints.

Efficacy of Bayesian Neural Networks in Active Learning

1 code implementation2 Apr 2021 Vineeth Rakesh, Swayambhoo Jain

By performing a comprehensive set of experiments, we show that Bayesian neural networks are more efficient than ensemble based techniques in capturing uncertainty.

Matrix Completion in the Unit Hypercube via Structured Matrix Factorization

1 code implementation30 May 2019 Emanuele Bugliarello, Swayambhoo Jain, Vineeth Rakesh

We tackle this challenge by using a two-fold approach: first, we transform this task into a constrained matrix completion problem with entries bounded in the unit interval [0, 1]; second, we propose two novel matrix factorization models that leverage our knowledge of the VFX environment.

Minimum Uncertainty Based Detection of Adversaries in Deep Neural Networks

no code implementations5 Apr 2019 Fatemeh Sheikholeslami, Swayambhoo Jain, Georgios B. Giannakis

The effectiveness of the novel detectors in the context of competing alternatives is highlighted through extensive tests for various types of adversarial attacks with variable levels of strength.

Unsupervised Demixing of Structured Signals from Their Superposition Using GANs

no code implementations ICLR Workshop DeepGenStruct 2019 Mohammadreza Soltani, Swayambhoo Jain, Abhinav Sambasivan

In this paper, we consider the observation setting in which the samples from a target distribution are given by the superposition of two structured components, and leverage GANs for learning of the structure of the components.

Improved Support Recovery Guarantees for the Group Lasso With Applications to Structural Health Monitoring

no code implementations29 Aug 2017 Mojtaba Kadkhodaie Elyaderani, Swayambhoo Jain, Jeffrey Druce, Stefano Gonella, Jarvis Haupt

This paper considers the problem of estimating an unknown high dimensional signal from noisy linear measurements, {when} the signal is assumed to possess a \emph{group-sparse} structure in a {known,} fixed dictionary.

Noisy Tensor Completion for Tensors with a Sparse Canonical Polyadic Factor

no code implementations8 Apr 2017 Swayambhoo Jain, Alexander Gutierrez, Jarvis Haupt

In this paper we study the problem of noisy tensor completion for tensors that admit a canonical polyadic or CANDECOMP/PARAFAC (CP) decomposition with one of the factors being sparse.

Block CUR: Decomposing Matrices using Groups of Columns

Noisy Inductive Matrix Completion Under Sparse Factor Models

no code implementations13 Sep 2016 Akshay Soni, Troy Chevalier, Swayambhoo Jain

This paper examines a general class of noisy matrix completion tasks where the underlying matrix is following an IMC model i. e., it is formed by a mixing matrix (a priori unknown) sandwiched between two known feature matrices.

On Convolutional Approximations to Linear Dimensionality Reduction Operators for Large Scale Data Processing

no code implementations25 Feb 2015 Swayambhoo Jain, Jarvis Haupt

In this paper, we examine the problem of approximating a general linear dimensionality reduction (LDR) operator, represented as a matrix $A \in \mathbb{R}^{m \times n}$ with $m < n$, by a partial circulant matrix with rows related by circular shifts.

Noisy Matrix Completion under Sparse Factor Models

no code implementations2 Nov 2014 Akshay Soni, Swayambhoo Jain, Jarvis Haupt, Stefano Gonella

This paper examines a general class of noisy matrix completion tasks where the goal is to estimate a matrix from observations obtained at a subset of its entries, each of which is subject to random noise or corruption.

Compressive Measurement Designs for Estimating Structured Signals in Structured Clutter: A Bayesian Experimental Design Approach

no code implementations21 Nov 2013 Swayambhoo Jain, Akshay Soni, Jarvis Haupt

This work considers an estimation task in compressive sensing, where the goal is to estimate an unknown signal from compressive measurements that are corrupted by additive pre-measurement noise (interference, or clutter) as well as post-measurement noise, in the specific setting where some (perhaps limited) prior knowledge on the signal, interference, and noise is available.
