Identifying features that leak information about sensitive attributes is a key challenge in the design of information obfuscation mechanisms. In this paper, we propose a framework to identify information-leaking features via information density estimation. Here, features whose information densities exceed a pre-defined…
New theorem shows black holes are real, with clearer event horizon.
problem Existence of black holes in spacetime.
method Analyzes radial tidal forces and strong energy condition.
result Proves timelike incompleteness of certain spacetimes.
We investigate the relation between economic growth and equality in a modified version of the agent-based asset exchange model (AEM). The modified model is a driven system that for a range of parameter space is effectively ergodic in the limit of an infinite system. We find that the belief that "a rising tide lifts all…
