Uncertainty Quantification for Local Model Explanations Without Model Access

1 code implementation13 Jan 2023 Surin Ahn, Justin Grana, Yafet Tamene, Kristian Holsheimer

We present a model-agnostic algorithm for generating post-hoc explanations and uncertainty intervals for a machine learning model when only a static sample of inputs and outputs from the model is available, rather than direct access to the model itself.

Content Filtering with Inattentive Information Consumers

no code implementations27 May 2022 Ian Ball, James Bono, Justin Grana, Nicole Immorlica, Brendan Lucier, Aleksandrs Slivkins

We develop a model of content filtering as a game between the filter and the content consumer, where the latter incurs information costs for examining the content.

Perturbing Inputs to Prevent Model Stealing

no code implementations12 May 2020 Justin Grana

We show how perturbing inputs to machine learning services (ML-service) deployed in the cloud can protect against model stealing attacks.

Deep Reinforcement Learning for Event-Driven Multi-Agent Decision Processes

1 code implementation19 Sep 2017 Kunal Menda, Yi-Chun Chen, Justin Grana, James W. Bono, Brendan D. Tracey, Mykel J. Kochenderfer, David Wolpert

The incorporation of macro-actions (temporally extended actions) into multi-agent decision problems has the potential to address the curse of dimensionality associated with such decision problems.
