Exploiting Multimodality

Overview

A typical robot is equipped with a variety of different sensors that may provide visual, haptic or auditory cues about the environment. While controllers are traditionally closed around explicit state representations, it is often hard to infer this kind of information from high-dimensional, noisy and heterogenous sensory data. We have worked on fusing the different sensor modalities for learning better representations to improve decision making. Check out some of our papers below!
