TGCD: A Framework for Generalized Category Discovery in Time-Series Data

AAAI 2026technical

Generalized Category Discovery (GCD) aims to classify labeled instances from known categories while discovering novel categories from unlabeled data. Despite recent progress in GCD for computer vision, existing GCD approaches largely rely on static final-step representations (in the visual domain),

Unsupervised Out-of-Distribution Detection Using Few in-Distribution Samples

ICASSP 2023accepted

This paper tackles the out-of-distribution (OOD) detection problem for natural language classifiers. While the previous OOD detection methods require large-scale in-distribution (ID) training data, we attack this problem from the few-shot perspective in an unsupervised manner where the training reli…

Refinement Matters: Textual Description Needs to be Refined for Zero-shot Learning

EMNLP 2022finding

Zero-Shot Learning (ZSL) has shown great promise at the intersection of vision and language, and generative methods for ZSL are predominant owing to their efficiency. Moreover, textual description or attribute plays a critical role in transferring knowledge from the seen to unseen classes in ZSL. Su…

Meta-Cognition-Based Simple And Effective Approach To Object Detection

ICASSP 2021accepted

Recently, many researchers have attempted to improve deep learning-based object detection models, both in terms of accuracy and operational speeds. However, frequently, there is a trade-off between speed and accuracy of such models, which encumbers their use in practical applications such as autonom…
