In the traditional supervised learning framework, active learning enables the learner to actively engage in the construction of the labeled training set by selecting a fixed-sized subset of unlabeled examples for labeling by an oracle, where the number of labels requested is referred to as the budget .

We consider logistic regression, and more generally, linear classification, in the streaming model. In our setting, we are given a dataset consisting ofT examples (xt,yt), where t [T], xt Rd, yt { 1,1}. The examples arrive one by one, and moreover, the nonzero coordinates of each examplext arrive one by one.

Pierre Huyghe's A.I. Art Monster Takes Over a Night Club in Berlin In "Liminals," a terrifying, overwhelming new installation, the artist erases the boundary between humans and the void. At the heart of the new piece is a fifty-five-minute film looped on an enormous screen. My preparation for "Liminals," an art work by Pierre Huyghe showing in Berlin, at Halle am Berghain, involved a small suitcase of books and articles about quantum physics, the science of sound, post-1968 France, relational aesthetics, and the sociology of techno. In the end, none of them proved useful. Among the heady possibilities dangled by the press release was an environment that would feature video, sound, light, and dust; exist outside of space and time; and operate in a state of quantum flux where "every moment is a maybe."

Iran's Digital Surveillance Machine Is Almost Complete After more than 15 years of draconian measures, culminating in an ongoing internet shutdown, the Iranian regime seems to be staggering toward its digital surveillance endgame. Iranian protesters gather on Enghelab (Revolution) Street during a demonstration in Tehran on January 8, 2026. Over the past four weeks, the Iranian government completely shut down connections to the global internet while its forces killed thousands of anti-regime protesters around the country. The shutdown follows years of Tehran imposing connectivity filtering, digital curfews, and total blackouts as part of previous attempts to quell unrest. Over more than 15 years, the regime has developed technological and systemic mechanisms to fundamentally control connectivity in the country--including an internal Iranian intranet known as the National Information Network (NIN).
