I am in Vancouver at ICML, and tomorrow I will present our newest paper "Partially Observable Reinforcement Learning with Memory Traces". We argue that eligibility traces are more effective than sliding windows as a memory mechanism for RL in POMDPs. 🧵

After all these reports of authors adding language instructions for LLM reviews in their papers I wanted to check this myself and I downloaded the .tex source from one of these papers. Here is an example. (I will not share the identity of the paper)

new preprint with the amazing @lviano.bsky.social and @neu-rips.bsky.social on offline imitation learning! learned a lot :) when the expert is hard to represent but the environment is simple, estimating a Q-value rather than the expert directly may be beneficial. lots of open questions left though!

new work on computing distances between stochastic processes ***based on sample paths only***! we can now: - learn distances between Markov chains - extract "encoder-decoder" pairs for representation learning - with sample- and computational-complexity guarantees read on for some quick details.. 1/n

Government officials are letting AI do their jobs. Badly
Offloading government responsibilities to AI can encourage discrimination, give wrong advice, and limit access to valid claims of asylum.

Disabled people have been pleading with folks to show solidarity for years. We saw the rising tide of eugenics the moment everyone declared Covid over & decided to leave us by the wayside. Pandemics give rise to fascism. What we’re seeing is the result of allowing disabled folks to be left behind

In the year of our Lord 2025... we are still putting on makeup on women without their consent. It's truly like feminism never happened 🙅‍♀️ (I have been ranting about this ever since people started using it to demonstrate GANs back in the 2010s, I can't believe it's still an "acceptable" task in AI!)

A relatedly bad idea is working on research you don't deeply believe in for pragmatic reasons. You start with "oh, it'll be a quick low-hanging fruit project" and 9 months later you're still working on it and in despair

Model-free deep RL algorithms like NFSP, PSRO, ESCHER, & R-NaD are tailor-made for games with hidden information (e.g. poker). We performed the largest-ever comparison of these algorithms. We find that they do not outperform generic policy gradient methods, such as PPO. arxiv.org/abs/2502.08938 1/N

I think I've found a way to articulate what bothers me about the trajectory of the modern tech industry (and to some extent... society). We are on this Earth to provide for each other. That's the "mission" of humanity as I see it. This is incompatible with what the tech industry seeks to do.

The rise of ChatGPT isn't just about AI—it's about how cluttered the web has become. Compare these recipes: ChatGPT gives me ingredients instantly, while a cooking website shows me an auto-playing video and a prompt to log into Google so I can see an ad
The image shows a ChatGPT conversation where someone requested a recipe for pancakes using whole rolled oats without a blender, with measurements in grams. The recipe ingredients are listed as:

- 150g whole rolled oats
- 250ml milk (dairy or plant-based)
- 2 large eggs (approximately 100g)
- 30g melted butter (or neutral oil) + extra for cooking
- 20g sugar (optional, adjust to taste)
- 8g baking powder (about 2 tsp)
- 2g salt (about 1/2 tsp)
- 5ml vanilla extract (optional)
This image shows a webpage from "the kitchn" website featuring a recipe for "Easy Oatmeal Pancakes." The recipe appears to be highly rated with 5 stars from 64 reviews. The page shows a navigation path of RECIPES > BREAKFAST > PANCAKES, and there's a banner at the top advertising "Our Laziest, Most Delicious Dinners Ever (Ready in 30 Minutes or Less)." The image also shows part of a photo featuring what appears to be melted butter being whisked into a mixture. There's a Google sign-in prompt overlaying part of the page.
