Towards Robust and Parameter-Efficient Knowledge Unlearning for LLMs

ICLR 2025poster

Large Language Models (LLMs) have demonstrated strong reasoning and memorization capabilities via pretraining on massive textual corpora. However, this poses risk of privacy and copyright violations, highlighting the need for efficient machine unlearning methods that remove sensitive data without re…

Learning to Unlearn: Instance-Wise Unlearning for Pre-trained Classifiers

AAAI 2024technical

Since the recent advent of regulations for data protection (e.g., the General Data Protection Regulation), there has been increasing demand in deleting information learned from sensitive data in pre-trained models without retraining from scratch. The inherent vulnerability of neural networks towards…

QASA: Advanced Question Answering on Scientific Articles

ICML 2023poster

Reasoning is the crux of intellectual thinking. While question answering (QA) tasks are prolific with various computational models and benchmark datasets, they mostly tackle factoid or shallow QA without asking deeper understanding. Dual process theory asserts that human reasoning consists of associ…

Rebalancing Batch Normalization for Exemplar-Based Class-Incremental Learning

CVPR 2023poster

Batch Normalization (BN) and its variants has been extensively studied for neural nets in various computer vision tasks, but relatively little work has been dedicated to studying the effect of BN in continual learning. To that end, we develop a new update patch for BN, particularly tailored for the…

Transferring Pre-trained Multimodal Representations with Cross-modal Similarity Matching

NeurIPS 2022accept

Despite surprising performance on zero-shot transfer, pre-training a large-scale multimodal model is often prohibitive as it requires a huge amount of data and computing resources. In this paper, we propose a method (BeamCLIP) that can effectively transfer the representations of a large pre-trained…

Point Cloud Augmentation With Weighted Local Transformations

ICCV 2021poster

Despite the extensive usage of point clouds in 3D vision, relatively limited data are available for training deep neural networks. Although data augmentation is a standard approach to compensate for the scarcity of data, it has been less explored in the point cloud literature. In this paper, we prop…

Self-supervised Auxiliary Learning with Meta-paths for Heterogeneous Graphs

NeurIPS 2020poster

Graph neural networks have shown superior performance in a wide range of applications providing a powerful representation of graph-structured data. Recent works show that the representation can be further improved by auxiliary tasks. However, the auxiliary tasks for heterogeneous graphs, which cont…
