Multi-Label Test-Time Adaptation with Bayesian Conditional Priors

ICML 2026poster

Vision--language models such as CLIP have shown strong zero-shot performance, but their reliability degrades in realistic multi-label settings under distribution shift. Standard test-time adaptation (TTA) methods either rely on costly gradient-based updates or adopt lightweight statistical schemes t…

Rethinking BCE Loss for Multi-Label Image Recognition with Fine-Tuning

CVPR 2026

Fine-tuning vision-language models such as CLIP has become the mainstream paradigm for multi-label image recognition, and prompt tuning is widely adopted due to its lightweight parameter cost and strong transferability. However, we find that when these methods use Binary Cross-entropy as the supervi

SlimInfer: Accelerating Long-Context LLM Inference via Dynamic Token Pruning

AAAI 2026technical

Long-context inference for Large Language Models (LLMs) is heavily limited by high computational demands. While several existing methods optimize attention computation, they still process the full set of hidden states at each layer, limiting overall efficiency. In this work, we propose SlimInfer, an

Batch Selection for Multi-Label Classification Guided by Uncertainty and Dynamic Label Correlations

AAAI 2025technical

The accuracy of deep neural networks is significantly influenced by the effectiveness of mini-batch construction during training. In single-label scenarios, such as binary and multi-class classification tasks, it has been demonstrated that batch selection algorithms preferring samples with higher un…

CHPO: Constrained Hybrid-action Policy Optimization for Reinforcement Learning

NeurIPS 2025poster

Constrained hybrid-action reinforcement learning (RL) promises to learn a safe policy within a parameterized action space, which is particularly valuable for safety-critical applications involving discrete-continuous hybrid action spaces. However, existing hybrid-action RL algorithms primarily focus…

POCE: Primal Policy Optimization with Conservative Estimation for Multi-constraint Offline Reinforcement Learning

CVPR 2024poster

Multi-constraint offline reinforcement learning (RL) promises to learn policies that satisfy both cumulative and state-wise costs from offline datasets. This arrangement provides an effective approach for the widespread application of RL in high-risk scenarios where both cumulative and state-wise co…

VOCE: Variational Optimization with Conservative Estimation for Offline Safe Reinforcement Learning

NeurIPS 2023poster

Offline safe reinforcement learning (RL) algorithms promise to learn policies that satisfy safety constraints directly in offline datasets without interacting with the environment. This arrangement is particularly important in scenarios with high sampling costs and potential dangers, such as autonom…
