Towards Interpreting Zoonotic Potential of Betacoronavirus Sequences With Attention

no code implementations18 Aug 2021 Kahini Wadhawan, Payel Das, Barbara A. Han, Ilya R. Fischhoff, Adrian C. Castellanos, Arvind Varsani, Kush R. Varshney

Current methods for viral discovery target evolutionarily conserved proteins that accurately identify virus families but remain unable to distinguish the zoonotic potential of newly discovered viruses.

Optimizing Molecules using Efficient Queries from Property Evaluations

1 code implementation3 Nov 2020 Samuel Hoffman, Vijil Chenthamarakshan, Kahini Wadhawan, Pin-Yu Chen, Payel Das

Machine learning based methods have shown potential for optimizing existing molecules with more desirable properties, a critical step towards accelerating new chemical discovery.

Effects of Naturalistic Variation in Goal-Oriented Dialog

1 code implementation Findings of the Association for Computational Linguistics 2020 Jatin Ganhotra, Robert Moore, Sachindra Joshi, Kahini Wadhawan

Existing benchmarks used to evaluate the performance of end-to-end neural dialog systems lack a key component: natural variation present in human conversations.

Interactive Visual Exploration of Latent Space (IVELS) for peptide auto-encoder model selection

no code implementations ICLR Workshop DeepGenStruct 2019 Tom Sercu, Sebastian Gehrmann, Hendrik Strobelt, Payel Das, Inkit Padhi, Cicero dos Santos, Kahini Wadhawan, Vijil Chenthamarakshan

We present the pipeline in an interactive visual tool to enable the exploration of the metrics, analysis of the learned latent space, and selection of the best model for a given task.

Co-regularized Alignment for Unsupervised Domain Adaptation

no code implementations NeurIPS 2018 Abhishek Kumar, Prasanna Sattigeri, Kahini Wadhawan, Leonid Karlinsky, Rogerio Feris, William T. Freeman, Gregory Wornell

Deep neural networks, trained with large amount of labeled data, can fail to generalize well when tested with examples from a \emph{target domain} whose distribution differs from the training data distribution, referred as the \emph{source domain}.

Unsupervised Domain Adaptation

PepCVAE: Semi-Supervised Targeted Design of Antimicrobial Peptide Sequences

no code implementations17 Oct 2018 Payel Das, Kahini Wadhawan, Oscar Chang, Tom Sercu, Cicero dos Santos, Matthew Riemer, Vijil Chenthamarakshan, Inkit Padhi, Aleksandra Mojsilovic

Our model learns a rich latent space of the biological peptide context by taking advantage of abundant, unlabeled peptide sequences.

Improved Neural Text Attribute Transfer with Non-parallel Data

no code implementations26 Nov 2017 Igor Melnyk, Cicero Nogueira dos santos, Kahini Wadhawan, Inkit Padhi, Abhishek Kumar

Text attribute transfer using non-parallel data requires methods that can perform disentanglement of content and linguistic attributes.

Learning Loss Functions for Semi-supervised Learning via Discriminative Adversarial Networks

no code implementations7 Jul 2017 Cicero Nogueira dos Santos, Kahini Wadhawan, Bo-Wen Zhou

We propose discriminative adversarial networks (DAN) for semi-supervised learning and loss function learning.
