QuantProb: Generalizing Probabilities along with Predictions for a Pre-trained Classifier

no code implementations25 Apr 2023 Aditya Challa, Snehanshu Saha, Soma Dhavala

We argue that between the choice of having a minimum calibration error on original distribution which increases across distortions or having a (possibly slightly higher) calibration error which is constant across distortions, we prefer the latter We hypothesize that the reason for unreliability of deep networks is - The way neural networks are currently trained, the probabilities do not generalize across small distortions.

Correcting Model Misspecification via Generative Adversarial Networks

no code implementations7 Apr 2023 Pronoma Banerjee, Manasi V Gude, Rajvi J Sampat, Sharvari M Hedaoo, Soma Dhavala, Snehanshu Saha

The "ABC-GAN" framework introduced is a novel generative modeling paradigm, which combines Generative Adversarial Networks (GANs) and Approximate Bayesian Computation (ABC).

Quantile LSTM: A Robust LSTM for Anomaly Detection In Time Series Data

no code implementations17 Feb 2023 Snehanshu Saha, Jyotirmoy Sarkar, Soma Dhavala, Santonu Sarkar, Preyank Mota

In particular, we propose Parametric Elliot Function (PEF) as an activation function (AF) inside LSTM, which saturates lately compared to sigmoid and tanh.

Hamiltonian Monte Carlo Particle Swarm Optimizer

no code implementations8 May 2022 Omatharv Bharat Vaidya, Rithvik Terence DSouza, Snehanshu Saha, Soma Dhavala, Swagatam Das

We introduce the Hamiltonian Monte Carlo Particle Swarm Optimizer (HMC-PSO), an optimization algorithm that reaps the benefits of both Exponentially Averaged Momentum PSO and HMC sampling.

Estimation and Applications of Quantiles in Deep Binary Classification

1 code implementation9 Feb 2021 Anuj Tambwekar, Anirudh Maiya, Soma Dhavala, Snehanshu Saha

We quantify the uncertainty of the class probabilities in terms of prediction intervals, and develop individualized confidence scores that can be used to decide whether a prediction is reliable or not at scoring time.
