Attention Mechanisms: Knowing Where to Look Improves Visual Reasoning

The human visual cortex uses attention mechanisms to discard irrelevant information as well as to efficiently allocate computational resources. It has inspired modern machine learning, where attention mechanisms are a vital part of memory modules and are used for modelling object interaction as well as solving complex reasoning tasks. In this talk, we explore attention mechanisms for visual tasks and show how they can help to track objects in real-world videos when used in a recurrent framework with a hierarchy of attention mechanisms. Attention is also able to model common assumptions we make about objects - that they do not appear out of nowhere and do not disappear into thin air. This insight lends itself to unsupervised detection and tracking of multiple objects - without any human supervision.
