Sure, only ~2 weeks to review 5 papers for ICLR. I am sure that all reviewers will have sufficient time to write careful and thoughtful reviews in the following weeks, since they have nothing else to do. It is insane to expect a fair reviewing system in these terms.

I got the classic NeurIPS reviews "why did you not compare with [completely unrelated method whose comparison would not help support any of the paper's claim]?" Questioning myself whether I should spend my weekend running this useless experiment or if I should argue with the reviewer.

While I really like the paper "Deep Reinforcement Learning at the Edge of the Statistical Precipice" (openreview.net/forum?id=uqv...), I have seen papers evaluating performance using only the IQM metric and claiming that it is a fairer metric than the mean based on this paper, which is simply wrong.

Deep Reinforcement Learning at the Edge of the Statistical Precipice

Our findings call for a change in how we report performance on benchmarks when using only a few runs, for which we present more reliable protocols accompanied with an open-source library.

I'm really glad to have been selected as one of the ICML 2025 Top Reviewers! Too bad I won't be able to go since my last submission was not accepted, even with scores Accept, Accept, Weak Accept, and Weak Reject 🫠

I am happy to announce that I successfully defended my PhD, entitled “Sample-Efficieny Multi-Task and Multi-Objective Reinforcement Learning by Combining Multiple Behaviors”! 🎉 These last years have been extremely fun, and I am very lucky to have collaborated with and met so many great people😄

Another must read for reinforcement learning. Answers many key questions for researchers; -Do I need multiple training runs? -How do I report model confidence? -And a great section on common mistakes to fend off reviewer 2 🧪 #DRL #reinforcementlearning #AI arxiv.org/abs/2304.01315

Empirical Design in Reinforcement Learning

Empirical design in reinforcement learning is no small task. Running good experiments requires attention to detail and at times significant computational resources. While compute resources available p...

Anyone else dislike the idea of papers being almost completely rewritten from scratch during ICLR rebuttals? This period should be used to address minor issues. I find a bit unfair authors expecting the reviewers to increase score when half of the relevant results were only shown during rebuttal.
