Researchers Define 'Machine Studying' As AI Domain Expertise Challenge

Original post

the best engineers I've met aren't the ones who know the most. they're the ones who can read a new codebase, product, or domain and rapidly build a mental model of it.

that's basically what "machine studying" is trying to solve for AI.

Continual learning is widely discussed right now, but mostly as improving on the job or avoiding catastrophic forgetting. But it has a different, difficult, and already urgent form:

Given nothing but a corpus of documents, how should AI systems develop expertise in a new, unfamiliar domain? We call this problem Machine Studying.

To compare procedures for machine studying, we start by defining expertise.

The corpus is always available at test time anyway, so a sufficiently intelligent non-expert agent could in principle always study during the exam.

What distinguishes an expert from a smart novice is a shift of the entire quality/cost curve: higher accuracy at the same budget, or the same accuracy at a smaller budget. We call the (appropriately weighted) area “expertise”, and the goal of studying is to raise expertise.
