Same Same, But Different: Conditional Multi-Task Learning for Demographic-Specific Toxicity Detection

1 code implementation14 Feb 2023 Soumyajit Gupta, Sooyong Lee, Maria De-Arteaga, Matthew Lease

We propose framing toxicity detection as multi-task learning (MTL), allowing a model to specialize on the relationships that are relevant to each demographic group while also leveraging shared properties across groups.

Fairly Accurate: Learning Optimal Accuracy vs. Fairness Tradeoffs for Hate Speech Detection

no code implementations15 Apr 2022 Venelin Kovatchev, Soumyajit Gupta, Anubrata Das, Matthew Lease

In this work, we first introduce a differentiable measure that enables direct optimization of group fairness (specifically, balancing accuracy across groups) in model training.

Range-Net: A High Precision Neural SVD

no code implementations29 Sep 2021 Soumyajit Gupta, Gurpreet Singh, Clint N. Dawson

For Big Data applications, computing a rank-$r$ Singular Value Decomposition (SVD) is restrictive due to the main memory requirements.

A Two-Stage Neural-Filter Pareto Front Extractor and the need for Benchmarking

no code implementations29 Sep 2021 Soumyajit Gupta, Gurpreet Singh, Matthew Lease

The Stage-1 neural network efficiently extracts the \textit{weak} Pareto front, using Fritz-John Conditions (FJC) as the discriminator, with no assumptions of convexity on the objectives or constraints.

Tail-Net: Extracting Lowest Singular Triplets for Big Data Applications

no code implementations28 Apr 2021 Gurpreet Singh, Soumyajit Gupta

However, a number of applications such as community detection, clustering, or bottleneck identification in large scale graph data-sets rely upon identifying the lowest singular values and the singular corresponding vectors.

SCA-Net: A Self-Correcting Two-Layer Autoencoder for Hyper-spectral Unmixing

no code implementations10 Feb 2021 Gurpreet Singh, Soumyajit Gupta, Clint Dawson

We show for the first time that a two-layer autoencoder (SCA), with $2FK$ parameters ($F$ features, $K$ endmembers), achieves error metrics that are scales apart ($10^{-5})$ from previously reported values $(10^{-2})$.

A Hybrid 2-stage Neural Optimization for Pareto Front Extraction

no code implementations27 Jan 2021 Gurpreet Singh, Soumyajit Gupta, Matthew Lease, Clint Dawson

The first stage (neural network) efficiently extracts a weak Pareto front, using Fritz-John conditions as the discriminator, with no assumptions of convexity on the objectives or constraints.

Range-Net: A High Precision Streaming SVD for Big Data Applications

no code implementations27 Oct 2020 Gurpreet Singh, Soumyajit Gupta, Matthew Lease, Clint Dawson

Although these methods are claimed to be applicable to scientific computations due to associated tail-energy error bounds, the approximation errors in the singular vectors and values are high when the aforementioned assumption does not hold.

Extracting Optimal Solution Manifolds using Constrained Neural Optimization

no code implementations13 Sep 2020 Gurpreet Singh, Soumyajit Gupta, Matthew Lease

However, such an approach is often restricted to a strict class of functions, deviation from which results in sub-optimal solution to the original problem.

Prevention is Better than Cure: Handling Basis Collapse and Transparency in Dense Networks

no code implementations22 Aug 2020 Gurpreet Singh, Soumyajit Gupta, Clint N. Dawson

We demonstrate through carefully chosen numerical experiments that the basis collapse issue leads to the design of massively redundant networks.

Higher Order Mutual Information Approximation for Feature Selection

no code implementations2 Dec 2016 Jilin Wu, Soumyajit Gupta, Chandrajit Bajaj

Feature selection is a process of choosing a subset of relevant features so that the quality of prediction models can be improved.
