Vision-driven River Following of UAV via Safe Reinforcement Learning using Semantic Dynamics Model
Vision-driven autonomous river following by Unmanned Aerial Vehicles is critical for applications such as rescue, surveillance, and environmental monitoring, particularly in dense riverine environments where GPS signals are unreliable. We formalize river following as a coverage control problem in which the reward function is submodular, yielding diminishing returns as more unique river segments are visited, thereby framing the task as a Submodular Markov Decision Process. First, we introduce Ma…

In recent months, UnitedHealth has targeted traditional journalists and news outlets, a prominent investor, a Texas doctor and activists like Ms. Strause and her father, who complained about a UnitedHealth subsidiary.
In legal letters and court filings, UnitedHealth has invoked last year’s murder of Brian Thompson, the chief executive of the company’s health insurance division,
to argue that intense criticism of the company risks inciting further violence.

The company has invoked the murder of an executive last year to complain about coverage in news outlets, on streaming services and on social media.

Towards Adaptive ML Benchmarks: Web-Agent-Driven Construction, Domain Expansion, and Metric Optimization
Recent advances in large language models (LLMs) have enabled the emergence of general-purpose agents for automating end-to-end machine learning (ML) workflows, including data analysis, feature engineering, model training, and competition solving. However, existing benchmarks remain limited in task coverage, domain diversity, difficulty modeling, and evaluation rigor, failing to capture the full capabilities of such agents in realistic settings. We present TAM Bench, a diverse, realistic, and st…

Crypto ATMs fueling criminal activity, Treasury warns
The Treasury Department warned that the massive increase in the number of crypto ATMs — convertible virtual currency kiosks — has been accompanied by a spike in the number of operators who fail to comply with anti-money laundering rules.
