Automated Mathematical Equation Structure Discovery for Visual Analysis
This work addresses the challenge of reducing human bias and intervention in equation discovery for computer vision, though it appears incremental by applying existing methods to a new domain.
The paper tackles the problem of automatically discovering mathematical equations for visual analysis, specifically to distinguish moving objects from background in video sequences, showing effectiveness in finding the best equation.
Finding the best mathematical equation to deal with the different challenges found in complex scenarios requires a thorough understanding of the scenario and a trial and error process carried out by experts. In recent years, most state-of-the-art equation discovery methods have been widely applied in modeling and identification systems. However, equation discovery approaches can be very useful in computer vision, particularly in the field of feature extraction. In this paper, we focus on recent AI advances to present a novel framework for automatically discovering equations from scratch with little human intervention to deal with the different challenges encountered in real-world scenarios. In addition, our proposal can reduce human bias by proposing a search space design through generative network instead of hand-designed. As a proof of concept, the equations discovered by our framework are used to distinguish moving objects from the background in video sequences. Experimental results show the potential of the proposed approach and its effectiveness in discovering the best equation in video sequences.
