What is Statistics? (Michael I. Jordan) | AI Podcast Clips

Lex Fridman

Statistics occupies a unique space between mathematics, science, and technology, serving as a discipline grounded in principles that allow for reasoned inference and decision-making with quantifiable confidence regarding errors. Historically formalized around 250 years ago under the name "inverse probability," the field emerged from early attempts to deduce underlying mechanisms of nature based on observed outcomes rather than predicting outcomes from known mechanics.…
