The mathematical architecture behind modern artificial intelligence
In short: This MIT lecture breaks down the core formulas that power neural networks. It moves from theoretical derivatives to practical application, showing how machines actually learn through back propagation.
Instructor Mark Seifter explores the foundational mathematics of neural nets, specifically focusing on sigmoid and performance functions along with their derivatives. The session bridges theory and practice by solving a specific problem from the Fall 2008 Quiz 3.
The lesson demonstrates how to execute one step of back propagation—the primary mechanism for training networks—and teaches students how to match different neural net structures with specific classifiers.
