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.

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.
