Cross-Week Review (1): How the Ideas of Seven Weeks Connect and Replace One Another | Harvard CS50 AI Topic Guide
Three kinds of relationship you see when the seven weeks are put side by side: an idea that returns in later weeks (the Markov chain from Week 2 is used again in Weeks 4 and 6; the linear combination of weights from Week 4 becomes Week 5's unit); an earlier week's tool that a later week depends on; and the lectures teaching one method, saying where it falls short, and moving to the next. Includes three cross-week examples and four cross-week self-check questions.
