Microsoft Recall adds an AI-based search feature to Windows 11 based on screenshots of the screen content. This also creates problems and concerns regarding data protection. Recall is a feature in Windows 11 that regularly creates screen recordings and saves them locally. This also involves processing with AI so that users can search through the data.

Emerging data-driven approaches, such as deep reinforcement learning (DRL), aim at on-the-field learning of powertrain control policies that optimize fuel economy and other performance metrics. Indeed, they have shown great potential in this regard for individual vehicles on specific routes or drive cycles. However, for fleets of vehicles that must service a distribution of routes, DRL approaches struggle with learning stability issues that result in high variances and challenge their practical deployment. In this paper, we present a novel framework for shared learning among a fleet of vehicles through the use of a distilled group policy as the knowledge sharing mechanism for the policy learning computations at each vehicle. We detail the mathematical formulation that makes this possible. Several scenarios are considered to analyze the functionality, performance, and computational scalability of the framework with fleet size. Comparisons of the cumulative performance of fleets using our proposed shared learning approach with a baseline of individual learning agents and another state-of-the-art approach with a centralized learner show clear advantages to our approach. For example, we find a fleet average asymptotic improvement of 8.5 percent in fuel economy compared to the baseline while also improving on the metrics of acceleration error and shifting frequency for fleets serving a distribution of suburban routes. Furthermore, we include demonstrative results that show how the framework reduces variance within a fleet and also how it helps individual agents adapt better to new routes.

This article studies how to intervene against statistical discrimination, when it is based on beliefs generated by machine learning, rather than by humans. Unlike beliefs formed by a human mind, machine learning-generated beliefs are verifiable. This allows interventions to move beyond simple, belief-free designs like affirmative action, to more sophisticated ones, that constrain decision makers in ways that depend on what they are thinking. Such mind reading interventions can perform well where affirmative action does not, even when the beliefs being conditioned on are possibly incorrect and biased.
