🌍 The climate crisis demands urgent action. But which actions are best?
Decision makers face tough trade-offs:
Policy A lowers emissions at home but increases reliance on imports.
Policy B cuts emissions long-term but raises unemployment short-term.
Policy C boosts jobs now but increases emissions in the near term.
None of these choices are simple. A policy that looks good locally may increase global emissions, or its effects may depend on what other countries d…

Sampling Complexity of TD and PPO in RKHS
We revisit Proximal Policy Optimization (PPO) from a function-space perspective. Our analysis decouples policy evaluation and improvement in a reproducing kernel Hilbert space (RKHS): (i) A kernelized temporal-difference (TD) critic performs efficient RKHS-gradient updates using only one-step state-action transition samples; (ii) a KL-regularized, natural-gradient policy step exponentiates the evaluated action-value, recovering a PPO/TRPO-style proximal update in continuous state-action spaces.…

Microsoft's AI tools still lag behind OpenAI's, as Microsoft struggles to create a cohesive AI experience and add new features by integrating OpenAI models (Austin Carr/Bloomberg)

This thread is brilliant, and a call to action.

The @annarborobserver.bsky.social newsletter had a decent summary of the dynamic at the #a2council Transportation Commission meeting last week (https://mailchi.mp/aaobserver/a2view-november-26-2025?e=476ffa7e6c ). But we need to take some time to talk in detail about why the city's presentation was so damaging and damning... (🧵)

Improving Aviation Safety Analysis: Automated HFACS Classification Using Reinforcement Learning with Group Relative Policy Optimization
Analyzing the human factors behind aviation accidents is crucial for preventing future incidents, yet traditional methods using the Human Factors Analysis and Classification System (HFACS) are limited by scalability and consistency. To address this, we introduce an automated HFACS classification framework for aviation safety analysis that utilizes Reinforcement Learning with Group Relative Policy Optimization (GRPO) to fine-tune a Llama-3.1 8B language model. Our approach incorporates a multi-c…

Saw this in a Sam’s Club in suburban Atlanta: Bijan Robinson who is a star running back for the Atlanta Falcon’s is prominently featured on the box of this 75” TCL flat screen TV.
PLEASE respond with your location and the name of the retailer, and the picture on the box if you live in a different area.
PLEASE boost for reach.
I’m very curious if this is a national deal for TCL or if they have many local deals with local stars featured. If this TV is sold internationally who…

"Protestival". Wat een geweldig concept ('geweldig' natuurlijk in strikt figuurlijke zin).

Australia’s ‘protestival’: kayaks, music, a push for climate change action – and the risk of arrest
Fossil fuel protesters are making their annual pilgrimage to the NSW city of Newcastle to draw attention to climate policy failure. Police will be there too, with a ‘zero tolerance approach’

David Sacks,
the Trump administration’s A.I. and crypto czar,
has helped formulate policies that aid his Silicon Valley friends
and many of his own tech investments.
Since January, Mr. Sacks, 53, has occupied one of the most advantageous moonlighting roles in the federal government,
influencing policy for Silicon Valley in Washington while simultaneously working in Silicon Valley as an investor.
Among his actions as the White House’s artificial intelligen…

U.S. District Judge Sara Ellis on Oct. 9 ordered “visible identification” that is “prominently displayed.”
But dozens of photographs of uniformed immigration agents shot by Chicago Sun-Times photojournalists in four separate locations since the court order show how the feds have fallen short.
The 80-plus photos show that not all officers are displaying a visible identification code that mixes numbers and letters during some of the most contentious recent immigration actions that…

IDs are mismatched, illegible — or still missing three weeks after judge’s order to immigration officers
In dozens of photographs at four locations, Chicago Sun-Times photojournalists documented federal officers failing to wear the “visible identification” needed to hold individuals accountable during the ongoing immigration “blitz.”
