FPI-DET: A FACE–PHONE INTERACTION DATASET FOR PHONE-USE DETECTION AND UNDERSTANDING

ICASSP 2026poster

The widespread use of mobile devices has created new challenges for vision systems in safety monitoring, workplace productivity assessment, and attention management. Detecting whether a person is using a phone requires not only object recognition but also an understanding of behavioral context, whic…

On the Discrimination and Consistency for Exemplar-Free Class Incremental Learning

IJCAI 2025

Exemplar-free class incremental learning (EF-CIL) is a nontrivial task that requires continuously enriching model capability with new classes while maintaining previously learned knowledge without storing and replaying any old class exemplars. An emerging theory-guided framework for CIL trains task-

DeepAccident: A Motion and Accident Prediction Benchmark for V2X Autonomous Driving

AAAI 2024technical

Safety is the primary priority of autonomous driving. Nevertheless, no published dataset currently supports the direct and explainable safety evaluation for autonomous driving. In this work, we propose DeepAccident, a large-scale dataset generated via a realistic simulator containing diverse acciden…

Harnessing Neural Unit Dynamics for Effective and Scalable Class-Incremental Learning

ICML 2024poster

Class-incremental learning (CIL) aims to train a model to learn new classes from non-stationary data streams without forgetting old ones. In this paper, we propose a new kind of connectionist model by tailoring neural unit dynamics that adapt the behavior of neural networks for CIL. In each training…

Towards Continual Learning Desiderata via HSIC-Bottleneck Orthogonalization and Equiangular Embedding

AAAI 2024technical

Deep neural networks are susceptible to catastrophic forgetting when trained on sequential tasks. Various continual learning (CL) methods often rely on exemplar buffers or/and network expansion for balancing model stability and plasticity, which, however, compromises their practical value due to pri…

Weighted Contrastive Learning With False Negative Control to Help Long-tailed Product Classification

ACL 2023industry

Item categorization (IC) aims to classify product descriptions into leaf nodes in a categorical taxonomy, which is a key technology used in a wide range of applications. Along with the fact that most datasets often has a long-tailed distribution, classification performances on tail labels tend to be…

Scale-Equivalent Distillation for Semi-Supervised Object Detection

CVPR 2022poster

Recent Semi-Supervised Object Detection (SS-OD) methods are mainly based on self-training, i.e., generating hard pseudo-labels by a teacher model on unlabeled data as supervisory signals. Although they achieved certain success, the limited labeled data in semi-supervised learning scales up the chall…
