Title
Modeling Data Structures for Effective and Explainable Visual Recognition
Abstract
Modern deep learning models for visual recognition are predominantly built upon the fully parametric, discriminative softmax classifier. Though straightforward, this de facto regime neglects the underlying data structure, and thereby suffers from poor explainability, and inferior robustness to out-of-distribution inputs. In this talk, taking image classification and segmentation as examples, I will present my recent work that addresses these limitations by revisiting the classic prototype theory and exemplar-based classifier. We further propose a new family of deep visual recognition models that learn generative, Gaussian Mixture Model (GMM) based classifiers with end-to-end discriminative representation in a compact and collaborative manner. Above efforts lay the solid foundation of effective, robust, and explainable visual recognition.
