Szymon Sidor (OpenAI research scientist) describes the rapid daily iteration and overnight training required to defeat professional players at The International.
“Because actually it's a little known fact, but from day to day, like each version of the experiment was not good enough to beat the next player, next, next day's professional.”

Sidor: Rigorous baseline optimization will advance AI more than complex architectures
“And you know, it's not the kind of sexy research that people want to see, where you have like some hierarchy of big RNN, but it actually, this kind of research, I think at this point will advance field the most.”

Sidor: Strong Engineering Is Much More Valuable at OpenAI than Writing Exotic Models
“So, so essentially becoming a good engineer for our team is much more valuable than, for example, people spending you know, months upon months implementing exotic models in TensorFlow.”

Insight
Sidor: Machine learning math is easier to learn than good engineering
“Getting good basics in linear algebra and in basic statistics, that's, especially when Doing experiments, it's easy to make like elementary statistics mistakes and linear algebra is just kind of most of what you need to know to like basic optimization as well …”

Sidor: AI research neglects understanding existing methods and limits
“And what people do is people kind of try to invent problems and the, such as solving some complicated games of character structure, and they try to Add kind of extra features to their models to combat those problems, but I think there's very little research ha…”

Sidor: OpenAI's RL bot beat its hand-coded bot after one to two weeks
“So I leave, there is nothing, I come back, there is this reinforcement learning bot, and actually, it's beating our scripted bot after, like a week worth of engineering effort. Possibly it was two weeks, but it was something very miniature compared to the deve…”

AssertionSupported
OpenAI Dota bot learned baiting behavior without explicit reward incentives
“It was like one of the major examples, one of the major examples of the things that we kind of didn't have explicit incentive for, and yet the bot actually learned them.”
