Learning Conjunctive Information Of Signals In Multi-Sensor Systems
ECAI 2020: 24TH EUROPEAN CONFERENCE ON ARTIFICIAL INTELLIGENCE(2020)
摘要
This paper proposes a novel deep learning method for extraction of the conjunctive information that describes the relationship between signals in multi-sensor systems to enhance the performance of the given classification task. The signals obtained from different sensors included in the multi-sensor systems are closely related. Handcrafted metrics have been used to extract the relationship between the signals in some work, which is hardly optimal for the given task. Our proposed method learns the pair-wise relationship from data to maximize the performance of the given task, which is fully data-driven, multi-aspect, and target-oriented. We demonstrate the effectiveness of the proposed method on a toy example and two real-world problems, i.e., activity recognition using accelerometer signals and emotional video classification using brain signals.
