Vision and Reasoning

Many vision and language tasks require commonsense reasoning beyond data-driven image and natural language processing. Cognitive Sciences and Active Vision literature points to an explicit iterative interaction among perception, reasoning, and memory (knowledge) modules (DeepIU ACS 2015).

Captioning

In our earliest attempt (CVIU 2017), we used a combination of image classification, reasoning with commonsense knowledge (extracted from training captions) to propose a Scene Description Graph as an intermediate representation for a natural image. We showed the efficacy of this representation through image captioning, image retrieval tasks (and QA case studies).

Visual QA, Image Puzzles and Visual Reasoning

We have proposed instantiations of this abstract architecture to solve image puzzles, VQA and visual reasoning tasks such as CLEVR. In our AAAI 2018 VQA, and UAI 2018 Puzzles work, we have proposed an explicit probabilistic soft logic layer on top of a neural architecture that helps integrate commonsense knowledge and induces post-hoc interpretability.

Later on, for an end-to-end (differentiable) integration of spatial knowledge, we explore a combination of knowledge distillation, probabilistic logic, and relational network in our WACV 2019 CLEVR.
