Learning Data Science: Why a High R^2 Can Be Misleading

A high $R^2$ can make a regression model look impressively accurate — but this number can be deceptive. If you want to understand why a high $R^2$ is not always a sign of a good model, read on!

The Magic of In-Context Learning (ICL): When Your Model Already Knows Your Data

Have you ever looked at a freshly plotted scatter plot and immediately thought, “Ah, this is clearly a logarithmic curve with some heteroskedastic noise,” without running a single line of modeling code? How do you do that? You don’t perform gradient descent in your head. You use your intuition!
