Google Machine Learning Crash Course (Korean)
Google's introductory machine learning course, fully translated into Korean — one of the few proper Korean-language courses in this catalog. Modules cover linear and logistic regression, classification, working with data, neural networks, embeddings, large language models, production ML systems and fairness, each labelled with an estimated study time so you can work through them in order. The linked page, 'Neural networks: interactive exercises', has you edit hidden layers and weights yourself and see which nodes' calculations are affected.

How to try it
Press the play (▶️) button in the widget to watch the hidden and output node values fill in, then add layers and nodes with the '+' buttons or edit a weight value and answer the questions below to check the explanation. The table of contents on the left moves you between modules, and a later exercise asks you to build a network that gets both training and test loss under 0.2. Korean is supported, though as the page states the text is machine-translated.
