Phased Exploration with Greedy Exploitation in Stochastic Combinatorial Partial Monitoring Games

Neural Information Processing Systems

Partial monitoring games are repeated games where the learner receives feedback that might be different from adversary's move or even the reward gained by the learner. Recently, a general model of combinatorial partial monitoring (CPM) games was proposed [1], where the learner's action space can be exponentially large and adversary samples its moves from a bounded, continuous space, according to a fixed distribution. The paper gave a confidence bound based algorithm (GCB) that achieves O(T2/3 log T) distribution independent and O(log T) distribution dependent regret bounds. The implementation of their algorithm depends on two separate offline oracles and the distribution dependent regret additionally requires existence of a unique optimal action for the learner. Adopting their CPM model, our first contribution is a Phased Exploration with Greedy Exploitation (PEGE) algorithmic framework for the problem.

This tool could show how consciousness works

MIT Technology Review

Transcranial focused ultrasound is a noninvasive way to stimulate the brain and see how it functions. How does the physical matter in our brains translate into thoughts, sensations, and emotions? It's hard to explore that question without neurosurgery. But in a recent paper, MIT philosopher Matthias Michel, Lincoln Lab researcher Daniel Freeman, and colleagues outline a strategy for doing so with an emerging tool called transcranial focused ultrasound. This noninvasive technology reaches deeper into the brain, with greater resolution, than techniques such as EEG and MRI. It works by sending acoustic waves through the skull to focus on an area of a few millimeters, allowing specific brain structures to be stimulated so the effects can be studied.


The Working Families Party Is Riding The Anti-AI Wave

Maurice Mitchell of the Working Families Party spoke at a press conference in Washington, DC on April 21, 2026. Get your news from a source that's not owned and controlled by oligarchs. Voters are anxious about losing their jobs to artificial intelligence, and key players across the political spectrum have started to notice. Now, the Working Families Party has rolled out a slate of policy proposals for the midterms, backed by more than two dozen Democratic candidates and representatives, that aims to address that anxiety. Their plan to counter AI-related job losses?
