Josh Bloom, UC Berkeley astronomy professor and co-founder/CTO of Wise.io, explains how high-dimensional machine learning models bypass traditional theoretical modeling by learning directly from historical patterns.
“Well, the point is, and this is sort of the conceit of all data-driven approaches, is that you don't need to have a theory about why something's gonna happen. The idea is that you've got enough data, both in, in terms of the number of examples, and then also sort of the dimensionality of the data, that you can train a very, ah, good grad student, or you can train a very good algorithm to learn from the past”

Machine Learning Tools Have Neglected Time Series Data

Bloom: Machine learning must focus on real-time future data over history
“In some sense that's the greatest imperative and like the gauntlet that I lay down in front of anyone is that you're not doing machine learning because it's cool and it's fun and you can learn something about the data from the past. You're trying to really use…”

Bloom: Machine learning software acts like virtualized graduate students at scale
“Because the software exists that can actually sift through and look at that data as if it's, you know, essentially virtualized graduate students with a huge amount of domain knowledge, and do this at scale it allows you to take more and more data.”
