HOMER: Provable Exploration in Reinforcement Learning

Last week at ICML 2020, Mikael Henaff, Akshay Krishnamurthy, John Langford and I had a paper on a new reinforcement learning (RL) algorithm that solves three key problems in RL: (i) global exploration, (ii) decoding latent dynamics, and (iii) optimizing a given reward function. Our ICML poster is here. The paper is a bit mathematically heavy...

Critical issues in digital contract tracing

I spent the last month becoming a connoisseur of digital contact tracing approaches since this seems like something where I might be able to help. Many other people have been thinking along similar lines (great), but I also see several misconceptions that even smart and deeply involved people are making. For the following a key distinction to understand...

What is the most effective policy response to the new coronavirus pandemic?

Disclaimer: I am not an epidemiologist, but there is an interesting potentially important pattern in the data that seems worth understanding. World healthcare authorities appear to be primarily shifting towards Social Distancing. However, there is potential to pursue a different strategy in the medium term that exploits a vulnerability of this disease:...

Coronavirus and Machine Learning Conferences

I’ve been following the renamed COVID-19 epidemic closely since potential exponentials deserve that kind of attention. The last few days have convinced me it’s a good idea to start making contingency plans for machine learning conferences like ICML. The plausible options happen to be structurally aligned with calls to enable reduced travel to machine...

Updates for the new decade

This blog has been quiet for the last year. I have quite a bit to write about but found myself often out of time between work at Microsoft, ICML duties, and family life. Nevertheless, I expect to get back to more substantive discussions as I adjust to the new load. In the meantime, I’ve updated the site in various ways: SSL now works, and mail for...

ICML has 3(!) Real World Reinforcement Learning Workshops

The first is Sunday afternon during the Industry Expo day. This one is meant to be quite practical, starting with an overview of Contextual Bandits and leading into how to apply the new Personalizer service, the first service in the world functionally supporting general contextual bandit learning. The second is Friday morning. This one is more...

Code submission should be encouraged but not compulsory

ICML, ICLR, and NeurIPS are all considering or experimenting with code and data submission as a part of the reviewer or publication process with the hypothesis that it aids reproducibility of results. Reproducibility has been a rising concern with discussions in paper, workshop, and invited talk. The fundamental driver is of course lack of reproducibility....

FAQ on ICML 2019 Code Submission Policy

ICML 2019 has an option for supplementary code submission that the authors can use to provide additional evidence to bolster their experimental results. Since we have been getting a lot of questions about it, here is a Frequently Asked Questions for authors. 1. Is code submission mandatory? No. Code submission is completely optional, and we anticipate...

ICML 2019: Some Changes and Call for Papers

The ICML 2019 Conference will be held from June 10-15 in Long Beach, CA — about a month earlier than last year. To encourage reproducibility as well as high quality submissions, this year we have three major changes in place. There is an abstract submission deadline on Jan 18, 2019. Only submissions with proper abstracts will be allowed to submit a...

Please vote

This is not at all related to Machine Learning. I lived in Squirrel Hill as a graduate student at Carnegie Mellon so the massacre there is feeling particularly immediate. While the person who did it is obviously culpable, the pattern of events makes it clear that others bear responsibility as well. This pattern includes an attempted bomber of Democrats...
