03 · Indexing and Broadcasting Real Data

Part III, Block 1 of Tensors for Machine Learning. Two practical skills: indexing — choosing exactly the rows, columns or values you want — and broadcasting — applying a smaller set of numbers across a larger array without copying them by hand.

This is also where the workshop’s central warning lands. Selecting the wrong column of real tumour data produces no error. It returns a different real measurement, your analysis continues, and it gives a confident, wrong answer.
