Confidence-based Deep Multimodal Fusion for Activity Recognition
Junho H. Choi, Jong‐Seok Lee · 2018
Human activity recognition using multimodal sensors is widely studied in recent days. In this paper, we propose an end-to-end deep learning model for activity recognition, which fuses features of multiple modalities based on their confidence scores that are automatically determined. The confidence scores efficiently regulate the level of contribution of each sensor. We conduct an experiment on the latest activity recognition dataset. The results confirm that our model outperforms existing methods. We submit the proposed model to the Sussex-Huawei Locomotion-Transportation (SHL) recognition challenge [23] with the team name "Yonsei-MCML."
