AI beats top ‘Dota 2’ players in one-on-one matches

Artificial intelligence isn’t just good at playing Go — it can also emerge victorious in the eSports arena. The Elon Musk-backed OpenAI team has developed a machine learning system that has beaten “many” of the best pro Dota 2 players in one-on-one matches, including star player Dendi during a live demonstration at The International. The trick wasn’t to teach the AI how to play the game — instead, it was to have the bot play many games against itself, and encourage ideal behavior as it learned the ropes over time.

The result is an AI that not only has the fundamentals nailed down, but understands the nuances that take human players a long time to master. It’s adept at tricks like zoning (preventing the enemy from hitting your creeps to deny them experience and gold) and raze faking (starting a raze animation to trick an enemy into dodging a non-existent attack). While its actions per minute aren’t any better than that of an average flesh-and-bone player, the choices make a huge difference. And it doesn’t take too long to learn, either; OpenAI’s creation can beat regular Dota 2 bots after an hour of learning, and beat the best humans after just two weeks.

Of course, these victories came about under controlled, ideal conditions. One-on-one matches are far less complex than standard five-on-five matches, and it’s notable that the machine learning system doesn’t use the full range of tactics you see from human rivals. OpenAI hopes to have its bot mastering five-on-fives by next year’s Invitational, though. And while Elon Musk is a bit hyperbolic when he says that Dota 2 is “vastly more complex” than Go, it’s true that even this limited accomplishment is impressive. The title not only involves much more freedom of movement than most board games, but depends on feinting, denial and other less-than-obvious tactics. What OpenAI has learned with Dota 2 might just translate to other fields where understanding subtleties can be crucial to success.

Existing EV batteries could be recharged five times faster

Lithium-ion batteries have massively improved in the last half-decade, but there are still issues. The biggest, especially for EVs, is that charging takes too long to make them as useful as regular cars for highway driving. Researchers from the University of Warwick (WMG) have discovered that we may not need to be so patient, though. They developed a new type of sensor that measures internal battery temperatures and discovered that we can probably recharge them up to five times quicker without overheating problems.

Overcharging a lithium-ion battery anode can lead to lithium buildup, which can break through a battery's separator, create a short-circuit and cause catastrophic failure. That can cause the electrolyte to emit gases and literally blow up the battery, so manufacturers impose strict charging power limits to prevent it.

Those limits are based on hard-to-measure internal temperatures, however, which is where the WMG probe comes in. It's a fiber optic sensor, protected by a chemical layer that can be directly inserted into a lithium-ion cell to give highly precise thermal measurements without affecting its performance.

The team tested the sensor on standard 18650 li-ion cells, used in Tesla's Model S and X, among other EVs. They discovered that they can be charged five times faster than previously thought without damage. Such speeds would reduce battery life, but if used judiciously, the impact would be minimized, said lead researcher Dr. Tazdin Amietszajew.

Faster charging as always comes at the expense of overall battery life but many consumers would welcome the ability to charge a vehicle battery quickly when short journey times are required and then to switch to standard charge periods at other times.

There's still some work to do. While the research showed the li-ion cells can support higher temperatures, EVs and charging systems would have to have "precisely tuned profiles/limits" to prevent problems. It's also not clear how battery makers would install the sensors in the cells.

Nevertheless, it shows a lot of promise for much faster charging speeds in the near future. Even if battery capacities stayed the same, charging in 5 minutes instead of 25 could flip a lot of drivers over to the green side.
