A Dataset and Architecture for Visual Reasoning with a Working Memory
This addresses visual and logical reasoning challenges in AI, particularly for video analysis and game play, though it is incremental as it builds on existing VQA and cognitive science work.
The authors tackled the problem of visual reasoning with memory by creating the COG dataset and a deep learning architecture, achieving competitive performance on diagnostic VQA datasets and zero-shot generalization to new tasks.
A vexing problem in artificial intelligence is reasoning about events that occur in complex, changing visual stimuli such as in video analysis or game play. Inspired by a rich tradition of visual reasoning and memory in cognitive psychology and neuroscience, we developed an artificial, configurable visual question and answer dataset (COG) to parallel experiments in humans and animals. COG is much simpler than the general problem of video analysis, yet it addresses many of the problems relating to visual and logical reasoning and memory -- problems that remain challenging for modern deep learning architectures. We additionally propose a deep learning architecture that performs competitively on other diagnostic VQA datasets (i.e. CLEVR) as well as easy settings of the COG dataset. However, several settings of COG result in datasets that are progressively more challenging to learn. After training, the network can zero-shot generalize to many new tasks. Preliminary analyses of the network architectures trained on COG demonstrate that the network accomplishes the task in a manner interpretable to humans.
