A unified Bayesian framework for interval hypothesis testing in clinical trials

no code implementations21 Feb 2024 Abhisek Chakraborty, Megan H. Murray, Ilya Lipkovich, Yu Du

The American Statistical Association (ASA) statement on statistical significance and P-values \cite{wasserstein2016asa} cautioned statisticians against making scientific decisions solely on the basis of traditional P-values.

Differentially private Bayesian tests

no code implementations27 Jan 2024 Abhisek Chakraborty, Saptati Datta

We present a novel differentially private Bayesian hypotheses testing framework that arise naturally under a principled data generative mechanism, inherently maintaining the interpretability of the resulting inferences.

Constrained Reweighting of Distributions: an Optimal Transport Approach

no code implementations19 Oct 2023 Abhisek Chakraborty, Anirban Bhattacharya, Debdeep Pati

The key idea is to ensure that the maximum entropy weight adjusted empirical distribution of the observed data is close to a pre-specified probability distribution in terms of the optimal transport metric while allowing for subtle departures.

Scalable Model-Based Gaussian Process Clustering

no code implementations14 Sep 2023 Anirban Chakraborty, Abhisek Chakraborty

Gaussian process is an indispensable tool in clustering functional data, owing to it's flexibility and inherent uncertainty quantification.

Fair Clustering via Hierarchical Fair-Dirichlet Process

no code implementations27 May 2023 Abhisek Chakraborty, Anirban Bhattacharya, Debdeep Pati

The advent of ML-driven decision-making and policy formation has led to an increasing focus on algorithmic fairness.

Bayesian Spike Train Inference via Non-Local Priors

no code implementations27 May 2023 Abhisek Chakraborty

Advances in neuroscience have enabled researchers to measure the activities of large numbers of neurons simultaneously in behaving animals.

Uncertainty Quantification

Robust probabilistic inference via a constrained transport metric

1 code implementation17 Mar 2023 Abhisek Chakraborty, Anirban Bhattacharya, Debdeep Pati

The proposed approach finds applications in a wide variety of robust inference problems, where we intend to perform inference on the parameters associated with the centering distribution in presence of outliers.
