Learning to Incentivize Improvements from Strategic Agents

Machine learning systems are often used in settings where individuals adapt their features to obtain a desired outcome. In such settings, strategic behavior leads to a sharp loss in model...

A Ranking Game for Imitation Learning

We propose a new framework for imitation learning---treating imitation as a two-player ranking-based game between a policy and a reward. In this game, the reward agent learns to satisfy pairwise...

Congratulations #teamcanada on the gold medal win in the juniors world cup #wjc #iihf !!

Impressive come back by Czechia to tie it up in the third period and a nerve-wracking OT, but we pulled it off #canada , wooohooo!!!

I don't feel as strongly about quote posts as I did in 2018. Personally, I am not a fan, but there is clearly a lot of demand for it. We're considering it.

I ran this poll way back in November (before migrating to this instance) and in light of the massive global Twitter outage right now I went back to dig up the results. Looks like 33% of the respondents were correct! Congratulations to the winners! Your prize is a brief period during which there is no Twitter platform.
