Generalizable Sensor-Based Activity Recognition via Categorical Concept Invariant Learning

AAAI 2025technical

Human Activity Recognition (HAR) aims to recognize activities by training models on massive sensor data. In real-world deployment, a crucial aspect of HAR that has been largely overlooked is that the test sets may have different distributions from training sets due to inter-subject variability inclu…

Manta: Enhancing Mamba for Few-Shot Action Recognition of Long Sub-Sequence

AAAI 2025technical

In few-shot action recognition (FSAR), long sub-sequences of video naturally express entire actions more effectively. However, the high computational complexity of mainstream Transformer-based methods limits their application. Recent Mamba demonstrates efficiency in modeling long sequences, but dire…

Understanding and Mitigating Miscalibration in Prompt Tuning for Vision-Language Models

ICML 2025poster

Confidence calibration is critical for the safe deployment of machine learning models in the real world. However, such issue in vision-language models like CLIP, particularly after fine-tuning, has not been fully addressed. In this work, we demonstrate that existing prompt tuning methods usually lea…

Your Pre-trained LLM is Secretly an Unsupervised Confidence Calibrator

NeurIPS 2025poster

Post-training of large language models is essential for adapting pre-trained language models (PLMs) to align with human preferences and downstream tasks. While PLMs typically exhibit well-calibrated confidence, post-trained language models (PoLMs) often suffer from over-confidence, assigning high c…

Open-Vocabulary Calibration for Fine-tuned CLIP

ICML 2024poster

Vision-language models (VLMs) have emerged as formidable tools, showing their strong capability in handling various open-vocabulary tasks in image recognition, text-driven visual content generation, and visual chatbots, to name a few. In recent years, considerable efforts and resources have been dev…
