Data Science Prerequisites - Numpy, Matplotlib, and Pandas in Python - Machine Learning Is Nothing but Geometry.

The video explains that machine learning is fundamentally a geometry problem, focusing on regression and classification. Regression involves finding the best fit line or curve for data points, while classification is about drawing boundaries between different groups of data. The video uses examples like predicting gender from height and weight, and disease prediction from blood pressure and BMI, to illustrate these concepts. The key takeaway is that machine learning is not magic but a systematic approach to understanding data through geometry.
