One Bit Matters: Understanding Adversarial Examples as the Abuse of Redundancy

no code implementations23 Oct 2018 Jingkang Wang, Ruoxi Jia, Gerald Friedland, Bo Li, Costas Spanos

Despite the great success achieved in machine learning (ML), adversarial examples have caused concerns with regards to its trustworthiness: A small perturbation of an input results in an arbitrary failure of an otherwise seemingly well-trained ML model.

A Deep Learning and Gamification Approach to Energy Conservation at Nanyang Technological University

no code implementations13 Sep 2018 Ioannis C. Konstantakopoulos, Andrew R. Barkan, Shiying He, Tanya Veeravalli, Huihan Liu, Costas Spanos

We propose the design and implementation of a large-scale network game with the goal of improving the energy efficiency of a building through the utilization of cutting-edge Internet of Things (IoT) sensors and cyber-physical systems sensing/actuation platforms.

Inverse Reinforcement Learning via Deep Gaussian Process

no code implementations26 Dec 2015 Ming Jin, Andreas Damianou, Pieter Abbeel, Costas Spanos

We propose a new approach to inverse reinforcement learning (IRL) based on the deep Gaussian process (deep GP) model, which is capable of learning complicated reward structures with few demonstrations.
