Re-evaluating Continual VQA: Toward Fair and Robust Evaluation for Multimodal Continual Learning

CVPR 2026

Continual Visual Question Answering (Continual VQA) poses unique challenges for multimodal continual learning, requiring models to incrementally acquire new knowledge while preserving visual-semantic grounding across tasks. However, existing benchmarks hinder fair and robust evaluation of such capab

Continual Gradient Low-Rank Projection Fine-Tuning for LLMs

ACL 2025long

Continual fine-tuning of Large Language Models (LLMs) is hampered by the trade-off between efficiency and expressiveness. Low-Rank Adaptation (LoRA) offers efficiency but constrains the model’s ability to learn new tasks and transfer knowledge due to its low-rank nature and reliance on explicit para…

Nonstationary Sparse Spectral Permanental Process

NeurIPS 2024poster

Existing permanental processes often impose constraints on kernel types or stationarity, limiting the model's expressiveness. To overcome these limitations, we propose a novel approach utilizing the sparse spectral representation of nonstationary kernels. This technique relaxes the constraints on k…

Overcoming Recency Bias of Normalization Statistics in Continual Learning: Balance and Adaptation

NeurIPS 2023poster

Continual learning entails learning a sequence of tasks and balancing their knowledge appropriately. With limited access to old training samples, much of the current work in deep neural networks has focused on overcoming catastrophic forgetting of old tasks in gradient-based optimization. However, t…
