Remaining-data-free Machine Unlearning by Suppressing Sample Contribution

ICLR 2026poster

Machine unlearning (MU) aims to remove the influence of specific training samples from a well-trained model, a task of growing importance due to the ``right to be forgotten.” The unlearned model should approach the retrained model, where forgetting data do not contribute to the training process. The…

Pursuing Feature Separation based on Neural Collapse for Out-of-Distribution Detection

ICLR 2025poster

In the open world, detecting out-of-distribution (OOD) data, whose labels are disjoint with those of in-distribution (ID) samples, is important for reliable deep neural networks (DNNs). To achieve better detection performance, one type of approach proposes to fine-tune the model with auxiliary OOD d…

Unified Gradient-Based Machine Unlearning with Remain Geometry Enhancement

NeurIPS 2024spotlight

Machine unlearning (MU) has emerged to enhance the privacy and trustworthiness of deep neural networks. Approximate MU is a practical method for large-scale models. Our investigation into approximate MU starts with identifying the steepest descent direction, minimizing the output Kullback-Leibler di…

Self-Ensemble Protection: Training Checkpoints Are Good Data Protectors

ICLR 2023poster

As data becomes increasingly vital, a company would be very cautious about releasing data, because the competitors could use it to train high-performance models, thereby posing a tremendous threat to the company's commercial competence. To prevent training good models on the data, we could add imper…
