Richard Zemel -- Controlling the Black Box: Learning Manipulable and Fair Representations

Abstract: Machine learning models, and more specifically deep neural networks, are achieving state-of-the-art performance on difficult pattern-recognition tasks such as object recognition, speech recognition, drug discovery, and more. However, deep networks are notoriously difficult to understand, both in how they arrive at and how to affect their responses. As these systems become more prevalent in real-world applications it is essential to allow users to exert more control over the learning system. In particular a wide range of applications can be facilitated by exerting some structure over the learned representations, to enable users to manipulate, interpret, and in some cases obfuscate the representations. In this talk I will discuss recent work that makes some steps towards these goals, allowing users to interact with and control representations.
