Spurious Correlations and Where to Find Them

no code implementations21 Aug 2023 Gautam Sreekumar, Vishnu Naresh Boddeti

Spurious correlations occur when a model learns unreliable features from the data and are a well-known drawback of data-driven learning.

On the Biometric Capacity of Generative Face Models

no code implementations3 Aug 2023 Vishnu Naresh Boddeti, Gautam Sreekumar, Arun Ross

Our capacity estimates indicate that (a) under ArcFace representation at a false acceptance rate (FAR) of 0. 1%, StyleGAN3 and DCFace have a capacity upper bound of $1. 43\times10^6$ and $1. 190\times10^4$, respectively; (b) the capacity reduces drastically as we lower the desired FAR with an estimate of $1. 796\times10^4$ and $562$ at FAR of 1% and 10%, respectively, for StyleGAN3; (c) there is no discernible disparity in the capacity w. r. t gender; and (d) for some generative models, there is an appreciable disparity in the capacity w. r. t age.

Neuro-DynaStress: Predicting Dynamic Stress Distributions in Structural Components

no code implementations19 Dec 2022 Hamed Bolandi, Gautam Sreekumar, Xuyang Li, Nizar Lajnef, Vishnu Naresh Boddeti

Therefore, to reduce computational cost while preserving accuracy, a deep learning model, Neuro-DynaStress, is proposed to predict the entire sequence of stress distribution based on finite element simulations using a partial differential equation (PDE) solver.

Physics Informed Neural Network for Dynamic Stress Prediction

no code implementations28 Nov 2022 Hamed Bolandi, Gautam Sreekumar, Xuyang Li, Nizar Lajnef, Vishnu Naresh Boddeti

Therefore, to reduce computational cost while maintaining accuracy, a Physics Informed Neural Network (PINN), PINN-Stress model, is proposed to predict the entire sequence of stress distribution based on Finite Element simulations using a partial differential equation (PDE) solver.
