CardioRiskNet: Attention-based CVAE-enabled GCN for Risk Prediction in STEMI

ICASSP 2025accepted

Cardiovascular diseases (CVDs) are a major cause of death worldwide, taking almost 18 million lives each year. ST Elevation Myocardial Infarction (STEMI) is one of the highest contributors to the same. The immediate 30-day period post-STEMI is critical in judging long-term patient outcomes. Thus, th…

Efficient Knowledge Editing via Minimal Precomputation

ACL 2025short

Knowledge editing methods like MEMIT are able to make data and compute efficient updates of factual knowledge by using a single sentence to update facts and their consequences. However, what is often overlooked is a “precomputation step”, which requires a one-time but significant computational cost.…

InterAct: Advancing Large-Scale Versatile 3D Human-Object Interaction Generation

CVPR 2025poster

While large-scale human motion capture datasets have advanced human motion generation, modeling and generating dynamic 3D human-object interactions (HOIs) remain challenging due to dataset limitations. Existing datasets often lack extensive, high-quality motion and annotation and exhibit artifacts s…

Lifelong Knowledge Editing requires Better Regularization

EMNLP 2025

Knowledge editing is a promising way to improve factuality in large language models, but recent studies have shown significant model degradation during sequential editing. In this paper, we formalize the popular locate-then-edit methods as a two-step fine-tuning process, allowing us to precisely ide

PokerBench: Training Large Language Models to Become Professional Poker Players

AAAI 2025technical

We introduce PokerBench - a benchmark for evaluating the poker-playing abilities of large language models (LLMs). As LLMs excel in traditional NLP tasks, their application to complex, strategic games like poker poses a new challenge. Poker, an incomplete information game, demands a multitude of skil…

SeqMMR: Sequential Model Merging and LLM Routing for Enhanced Batched Sequential Knowledge Editing

ACL 2025finding

Model knowledge editing enables the efficient correction of erroneous information and the continuous updating of outdated knowledge within language models. While existing research has demonstrated strong performance in single-instance or few-instance sequential editing and one-time massive editing s…

Sylber: Syllabic Embedding Representation of Speech from Raw Audio

ICLR 2025poster

Syllables are compositional units of spoken language that efficiently structure human speech perception and production. However, current neural speech representations lack such structure, resulting in dense token sequences that are costly to process. To bridge this gap, we propose a new model, Sylbe…

ActNeRF: Uncertainty-aware Active Learning of NeRF-based Object Models for Robot Manipulators using Visual and Re-orientation Actions

IROS 2024

Manipulating unseen objects is challenging without a 3D representation, as objects generally have occluded surfaces. This requires physical interaction with objects to build their internal representations. This paper presents an approach that enables a robot to rapidly learn the complete 3D model of

Model Editing at Scale leads to Gradual and Catastrophic Forgetting

ACL 2024findings

Editing knowledge in large language models is an attractive capability that allows us to correct incorrectly learned facts during pre-training, as well as update the model with an ever-growing list of new facts. While existing model editing techniques have shown promise, they are usually evaluated u…

Rebuilding ROME : Resolving Model Collapse during Sequential Model Editing

EMNLP 2024main

Recent work using Rank-One Model Editing (ROME), a popular model editing method, has shown that there are certain facts that the algorithm is unable to edit without breaking the model. Such edits have previously been called disabling edits. These disabling edits cause immediate model collapse and li…

Acoustics Based Intent Recognition Using Discovered Phonetic Units for Low Resource Languages

ICASSP 2021accepted

With recent advancements in language technologies, humans are now speaking to devices. Increasing the reach of spoken language technologies requires building systems in local languages. A major bottleneck here are the underlying data-intensive parts that make up such systems, including automatic spe…
