Generating Artificial Data for Private Deep Learning
In this paper, we propose generating artificial data that retain statistical
properties of real data as the means of providing privacy with respect to the
original dataset. We use generative adversarial network to draw
privacy-preserving artificial data samples and derive an empirical method to
assess the risk of information disclosure in a differential-privacy-like way.
Our experiments show that we are able to generate artificial data of high
quality and successfully train and validate machine learning models on this
data while limiting potential privacy loss.Comment: Privacy-Enhancing Artificial Intelligence and Language Technologies,

Learning to cope with an open world
Science has developed detailed and well-founded theories for analyzing the behavior of artifacts. For example, Boeing was able to correctly verify an entirely new airplane, the Boeing 777, before any prototype was even built. However, there are few theories, and no computer systems, that would allow us to design structures with a similar degree of automatio
Exploring case-Based building design—CADRE
Case-based design promises important advantages over rule-based design systems. However, the actual implementation of the paradigm poses many problems which put the advantages into question. In our work on CADRE, a case-based building design system, we have encountered seven fundamental problems which we think are common to most case-based design systems. We describe the problems and the ways we either solved or worked around them in the CADRE system. This leads us to conclusions about the general applicability of case-based reasoning to building desig
Courtesy as a Means to Coordinate
We investigate the problem of multi-agent coordination under rationality
constraints. Specifically, role allocation, task assignment, resource
allocation, etc. Inspired by human behavior, we propose a framework (CA^3NONY)
that enables fast convergence to efficient and fair allocations based on a
simple convention of courtesy. We prove that following such convention induces
a strategy which constitutes an -subgame-perfect equilibrium of the
repeated allocation game with discounting. Simulation results highlight the
effectiveness of CA^3NONY as compared to state-of-the-art bandit algorithms,
since it achieves more than two orders of magnitude faster convergence, higher
efficiency, fairness, and average payoff.Comment: Accepted at AAMAS 2019 (International Conference on Autonomous Agents

Deep Bayesian Trust : A Dominant and Fair Incentive Mechanism for Crowd
An important class of game-theoretic incentive mechanisms for eliciting
effort from a crowd are the peer based mechanisms, in which workers are paid by
matching their answers with one another. The other classic mechanism is to have
the workers solve some gold standard tasks and pay them according to their
accuracy on gold tasks. This mechanism ensures stronger incentive compatibility
than the peer based mechanisms but assigning gold tasks to all workers becomes
inefficient at large scale. We propose a novel mechanism that assigns gold
tasks to only a few workers and exploits transitivity to derive accuracy of the
rest of the workers from their peers' accuracy. We show that the resulting
mechanism ensures a dominant notion of incentive compatibility and fairness
