What is machine learning?
- In 1959, Arthur Samuel defined machine learning as “A field of study that gives computers the ability to learn without being explicitly programmed”.
- IBM created a program that could play chess, called Deep Blue. The chess grand master, Gary Kasparov competed with Deep Blue in 1996 and 1997 respectively in 2 games of chess. The results of both the games are as shown below.
Supervised machine learning model:
In the first step, we train the machine with known data so that it learns something from it.
In the second step we expect the machine to utilize the knowledge it gained in the previous step and classify a new unknown data point.
In the third step, the model is evaluated on the basis of how accurately it has classified the unknown data.
