Inducing Semantic Grouping of Latent Concepts for Explanations: An Ante-Hoc Approach

Self-explainable deep models are devised to represent the hidden concepts in the dataset without requiring any posthoc explanation generation technique. We worked with one of such models motivated by explicitly representing the classifier function as a linear function and showed that by exploiting probabilistic latent and properly modifying different parts of the model can result better explanation as well as provide superior predictive performance. Apart from standard visualization techniques, we proposed a new technique which can strengthen human understanding towards hidden concepts. We also proposed a technique of using two different self-supervision techniques to extract meaningful concepts related to the type of self-supervision considered and achieved significant performance boost. The most important aspect of our method is that it works nicely in a low data regime and reach the desired accuracy in a few number of epochs. We reported exhaustive results with CIFAR10, CIFAR100 and AWA2 datasets to show effect of our method with moderate and relatively complex datasets.
