keras tutorialextensible API. Minimal structure - easy to achieve the result without any frills. It supports multiple platforms and backends. It is user friendly framework which runs on both CPU and GPU. Network (ANN) was invented by psychologist Frank Rosenblatt, in the year of 1958. ANNs are made up of multiple nodes which is similar to neurons. Nodes are tightly interconnected and organized into different represented as below: 4.
