DEFT: Data Efficient Fine-Tuning for Pre-Trained Language Models via Unsupervised Core-Set Selection

no code implementations25 Oct 2023 Devleena Das, Vivek Khetan

Recent advances have led to the availability of many pre-trained language models (PLMs); however, a question that remains is how much data is truly needed to fine-tune PLMs for downstream tasks?

Reprogramming Pretrained Language Models for Antibody Sequence Infilling

1 code implementation5 Oct 2022 Igor Melnyk, Vijil Chenthamarakshan, Pin-Yu Chen, Payel Das, Amit Dhurandhar, Inkit Padhi, Devleena Das

Results on antibody design benchmarks show that our model on low-resourced antibody sequence dataset provides highly diverse CDR sequences, up to more than a two-fold increase of diversity over the baselines, without losing structural integrity and naturalness.

Explainable Knowledge Graph Embedding: Inference Reconciliation for Knowledge Inferences Supporting Robot Actions

1 code implementation4 May 2022 Angel Daruna, Devleena Das, Sonia Chernova

Results from our algorithmic evaluation affirm our model design choices, and the results of our user studies with non-experts support the need for the proposed inference reconciliation framework.

Semantic-Based Explainable AI: Leveraging Semantic Scene Graphs and Pairwise Ranking to Explain Robot Failures

no code implementations8 Aug 2021 Devleena Das, Sonia Chernova

Our framework autonomously captures the semantic information in a scene to produce semantically descriptive explanations for everyday users.

Explainable Activity Recognition for Smart Home Systems

no code implementations20 May 2021 Devleena Das, Yasutaka Nishimura, Rajan P. Vivek, Naoto Takeda, Sean T. Fish, Thomas Ploetz, Sonia Chernova

In this work, we build on insights from Explainable Artificial Intelligence (XAI) techniques and introduce an explainable activity recognition framework in which we leverage leading XAI methods to generate natural language explanations that explain what about an activity led to the given classification.

Explainable AI for Robot Failures: Generating Explanations that Improve User Assistance in Fault Recovery

no code implementations5 Jan 2021 Devleena Das, Siddhartha Banerjee, Sonia Chernova

In order for error explanations to be meaningful, we investigate what types of information within a set of hand-scripted explanations are most helpful to non-experts for failure and solution identification.
