Article 1: Why Machine Learning? – Apurba Learns ML

For those who aren't familiar with the show, it depicts an all-seeing AI that can predict crime and other immoral acts before they even happen and passes on the information to the Government. One of the episodes of the show illustrates the origin of the Machine, where its creator -- Harold Finch -- is teaching it to distinguish between good and bad by showing it "examples". This is a perfect instance of Supervised learning -- we have a data-set or example set with the right answers given. Afterwards, we expect the computer to predict things based on the data-set. Now, to be a bit more specific, the above scenario depicts "Classification", meaning that the predicted output will fall into one of two or more discrete categories -- "good" and "bad" in our case.
