Evaluating Generalizability of Deep Learning Models Using Indian-COVID-19 CT Dataset

1 code implementation28 Dec 2022 Suba S, Nita Parekh, Ramesh Loganathan, Vikram Pudi, Chinnababu Sunkavalli

One of the major concerns in using ma-chine learning (ML) approaches for automatic processing of CT scan images in clinical setting is that these methods are trained on limited and biased sub-sets of publicly available COVID-19 data.

Practice Makes a Solver Perfect: Data Augmentation for Math Word Problem Solvers

Scalable, Semi-Supervised Extraction of Structured Information from Scientific Literature

no code implementations WS 2019 Kritika Agrawal, Aakash Mittal, Vikram Pudi

In this paper, we propose a novel, scalable, semi-supervised method for extracting relevant structured information from the vast available raw scientific literature.

Sequential Variational Autoencoders for Collaborative Filtering

1 code implementation25 Nov 2018 Noveen Sachdeva, Giuseppe Manco, Ettore Ritacco, Vikram Pudi

We introduce a recurrent version of the VAE, where instead of passing a subset of the whole history regardless of temporal dependencies, we rather pass the consumption sequence subset through a recurrent neural network.
