Proud to announce that Meta-World+ was accepted to NeurIPs, Datasets and Benchmarks! Meta-World is a common benchmark for multi-task and meta-RL research! However, it was very difficult to do effective science with Meta-World as different versions produce different results.

As Transactions on Machine Learning Research (TMLR) grows in number of submissions, we are looking for more reviewers and action editors. Please sign up!

Only one paper to review at a time and <= 6 per year, reviewers report greater satisfaction than reviewing for conferences!

Ever since I made a video about Fourier Transforms, one of the most requested topics on the channel has been its close cousin, the Laplace Transform.

I've been having a lot of fun animating a mini-series about this topic, and the main part is now out.

But what is a Laplace Transform?

I can also vouch for this plan (minus the work visa part) 😅

This is absolutely awesome. I am so pleased for everyone involved and particularly for people with Huntington's disease who will benefit.
Also, this is the first example I know of where gene therapy might well prevent dementia. Onwards to FTD!

🚨Our NeurIPS 2025 competition Mouse vs. AI is LIVE!

We combine a visual navigation task + large-scale mouse neural data to test what makes visual RL agents robust and brain-like.

Top teams: featured at NeurIPS + co-author our summary paper. Join the challenge!

Whitepaper: arxiv.org/abs/2509.14446
Mouse vs. AI: A Neuroethological Benchmark for Visual Robustness and Neural Alignment
Visual robustness under real-world conditions remains a critical bottleneck for modern reinforcement learning agents. In contrast, biological systems such as mice show remarkable resilience to environ...

Was this not… what critical AI researchers have been saying this entire time?

"In a landmark study, OpenAI researchers reveal that large language models will always produce plausible but false outputs, even with perfect data, due to fundamental statistical and computational limits."

Meta-world is still very much the go to for multi task and meta-RL research but it has some real failings that Reggie fixes up here!

Very happy this work got into #NeurIPS2025, it was a big effort that Reggie led, and I'm glad it was worth the work!
We've already been using Meta world+ in a lot of our research, and so should you!
Let's chat at #NeurIPS2025 !

To further improve the user experience when using Meta-World+, we streamline and improve the experience of creating environments such that users have both full control of the settings used to create their environments, while also ensuring that environments are created in the correct manner.

To disambiguate the results from the different versions of the benchmark, we implement and re-run experiments across several key multi-task and meta-RL algorithms, on both the V1 and V2 reward functions.
reggiemclean.bsky.social
What has changed between V1 and V2…? The reward functions! Here we find that the per-timestep rewards in all tasks have wildly different scales across the V1 and V2 reward functions. This affects the ability of the value function to approximate the state-action value functions (right panel)

We can highlight the performance difference between different versions of Meta-World by running a simple algorithm with both the V1 and V2 versions of Meta-World.
