Want to get up to speed on what’s happening in robot learning for manipulation? Oliver Kroemer, George Konidaris, and I have just released a new survey paper: http://arxiv.org/abs/1907.03146 . And please let us know if there is important work we missed — it is a huge and growing field!

#AcademicTwitter: I see overwhelming discussion on the downsides of academia. I worry what this does to the hope & inspiration of grad students with ambitions to go into academia. Given that I think#academia is the best job ever, my thoughts on life as an academic. A thread

1/ Dear friends (and P.I.s), in these volatile times, do spare a thought for students of Iranian origin, especially those studying in the US. The past decade was devastating for most of us who had close ties to Iran, no matter what political background we came from.

This is great and more of us should do it. I met with a less ambitious number, but it was the highlight of NeurIPS for me. Fav part was learning about what opportunities had been most impactful in the journey of underrepresented students and the great work that they went on to dohttps://twitter.com/hannawallach/status/1207352043851177986 …

Opinion: ML conf ACs have too much subjective tastemaking power and rejection quotas are arbitrary. Proposal: accept papers via pre-set score thresholds; the job of AC becomes convincing reviewers to move their scores, but that is the AC's only mechanism of influence. Thoughts?

Simple potential solution to prevent works like these from being published in our venues: Add a question in the review form about whether the submission raises ethical concerns. If a reviewer answers yes then the paper gets a second look before a reject/review decision is made. https://twitter.com/alexhanna/status/1205214184679649280 …

Providing probabilistic guarantees for RL and imitation learning is v. challenging in data-poor settings (e.g. robotics). I'll be speaking at the NeurIPS Safety and Robustness Workshop on Friday (2:40pm) about techniques that begin to address this issue.https://sites.google.com/view/neurips19-safe-robust-workshop …

Really excited for
#NeurIPS2019 next week and to present our spotlight on credit assignment :) https://papers.nips.cc/paper/9413-hindsight-credit-assignment … tl;dr We can rewrite value functions in terms of a hindsight quantity that explicitly captures credit assignment and get a whole new family of RL algs!

6/ Many of these are easier said than done given the shortage of qualified reviewers / ACs. And I still think better decisions were made via this model than in many other conferences. Nonetheless, I found myself frequently frustrated during the process. Would love to hear ideas!

5/n Don't invite back reviewers that didn't respond to rebuttals: The iterative process is awesome when it works, but often some (or all!) of the reviewers don't respond, making it incredibly difficult to fairly judge the impact of the rebuttal without a huge amount of effort.

4/n Don't "calibrate" scores: ACs were sent adjusted scores based on if reviewers tended to be more positive or negative than their peers overall. IMO this just adds noise and encourages ACs to act as a threshold function rather than adjust by carefully reading reviews.

3/n Have dedicated meta-reviewers, or lower AC paper load: 22 papers is simply too many if ACs are expected to lead productive discussions and provide high quality meta-reviews, given the extensive back-and-forth ICLR model.

2/n Finer-grained scoring: Restricting scores to 1,3,6,8 led to something like half my assigned papers being 6/6/3 or 6/3/3. No one wants to give a 1 or an 8 except in extreme circumstances, so almost all granularity is lost and decision making is unnecessarily hard.

1/n There's a lot to like about the pioneering
@iclr_conf review model, but I'm feeling somewhat negative about my experience as an area chair this year. Some opinions about what could be improved:Prikaži ovu nitHvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -
I'm often critical of OpenAI, but this is great work that will support deeper inquiry into generalization in RL.https://twitter.com/OpenAI/status/1201909508009627649 …

Eventually Frank will be decommissioned after telling one too many off-color jokes at work. Gary Marcus will intervene to try to save him -- it wasn't his fault, it was just in his corpus. But it will be too late. We'll miss you Frank.
