Learning when data is hard to acquire

Research into nuclear fusion is currently limited by researchers’ ability to run experiments. While there are dozens of active tokamaks around the world, they’re expensive machines and in high demand. For example, TCV can only sustain the plasma in a single experiment for up to three seconds, after which it needs 15 minutes to cool down and reset before the next attempt. Not only that, multiple research groups often share use of the tokamak, further limiting the time available for experiments.

Given the curr
