Machine Learning: How to Make a Good Prediction

Unsupervised learning would be like the image i've got here imagine just an image full of lots of dots. The algorithm will say okay i found these three clusters that seem to be together so they may be similar and this could then suddenly find oh i've got three kinds of customers that have different needs or maybe you're what state you're in, things like that right? It's not too hard to guess that this algorithm is not going to be a great algorithm because a number of square feet and number of bedrooms probably tells you very little unless you also know  what your location is within the state Things like that are part of machine learning is figuring out what are the right features to
