Anyone have a favorite blog or newsletter focusing on RL? Something not super focused on LLMs would be wonderful. 🤖🧠

Quick notes from this nice CCAT panel on funding smart infrastructure. I used to think this stuff was boring, but now I recognize that nothing can happen without money. In short: We have smart phones and smart cars, why don't we have smart roads? 👇 www.youtube.com/watch?v=nEtw...

Did you remember all the things to do before sharing a figure? Remove "_" from the labels save as pdf ... A lot of deeper tips to writing are in the shared document, but somehow this practical list was always the most popular. Good luck in #neurips docs.google.com/document/d/1... 🧠🤖📈 #LLM #AI

What if there were a workshop dedicated to small-scale, reproducible experiments? What if this were at ICML 2025? What if your submission (due May 22nd) could literally be a Jupyter notebook?? Pretty excited this is happening. Spread the word! sites.google.com/view/moss202...

Speed cameras save lives but many local authorities can’t afford to operate them because 100% of fines go straight to the Treasury. Local authorities should at least be able to retain enough of the revenue to cover the overheads of running schemes. www.bbc.co.uk/news/article...

A typical European car is parked 92% of the time. It spends 1/5th of its driving time looking for parking. Its 5 seats only move 1.5 people. 86% of its fuel never reaches the wheels, and most of the energy that does, moves the car, not the people. Sound efficient? HT @ellenmacarthurfdn.bsky.social

And how about the effect on students’ learning performance of unregulated use of ChatGPT, i.e., for homework help?

I wrote something up for AI people who want to get into bluesky and either couldn't assemble an exciting feed or gave up doomscrolling when their Following feed switched to talking politics 24/7.

You can’t cut funding to universities, signal to kids that using ChatGPT to write the papers is ok, and expect professors to save the day and the educational system without financial support to completely overhaul the curriculum. You can’t just wave your hands and hope for the best.

Our new NEC HSR report is out. The headline is HSR for under ~$20 billion. The substance is we can manage what we have more intelligently if we move away from our brute force approach to infrastructure. @alonlevy.bsky.social & Devin Wilkins did the heavy lifting: transitcosts.com/north-east-c...

Cornell engineering prof: "Oh, so you cover the #EV world? Total dead end. Hydrogen cars are about to come into their own." Me: "Why do you say that?" Him: "Carrying around 1,000 lbs of excess weight is absurd. Hydrogen is the answer; Toyota + BMW have solved it." (1 of 2)

"Under the change, any Level 2 crash that is so bad it needs a tow truck to come will no longer be required to be reported if it doesn’t result in death or injury or air-bag deployment. "But if a tow truck is called for crashes of vehicles using [fully automated driving], it has to be reported."

This is huge, I don't think there is any Substack that could excite me more than this! Finally someone is doing a project to cover transit in Asia, and China specifically in depth!

I guess this shouldn't come as a huge surprise, but State DOTs have lost ~10% of their FTE workforce since 2006. Also worth noting that the US population grew by over 10% during that same period.

We are on the front page of MIT today! This is our upcoming ICLR 2025 paper, which uses deep learning to avoid redundant calculations in large scheduling problems. We introduce a method called Learning-guided Rolling Horizon Optimization (L-RHO). Check it out here! news.mit.edu/2025/faster-...

The Gurobi workshop at the Analytics+ conference had many interesting updates. First, Xavier Nodet talked about advances in mixed-integer non linear programming, including the NLExpr object and an outline of how the nonlinear solver uses outer approximations and spatial branch-and-bound. 🧵1/N

What a time to be alive. Every year, I would dread updating my research statement. Armed with writing assistants Claude and ChatGPT, it's actually fun this time.
