Deep Learning is sub set of Machine Learning inspired by human brain. It's is also known as artificial neural networks cause the learning process uses the neural network. Learning can be Supervised, Unsupervised and Reinforcement learning. Deep learning is used to build predictive model. Deep Learning is used in each and every field as healthcare, finance, entertainment, business, logistics and many more.

For example, we made a machine where gives the different  image of dog and cat. In machine learning we have to give up a description of dog and cat like color, size etc. But Deep learning means selecting cat and dog through the Artificial Neural Network with Human notation. 

There are lots of frameworks used for Deep Learning they are:

• Tensorflow
• Keras
• pyTorch
• Caffe
• DL4J 
• Microsoft Cognitive toolkit

Tensoflow is used mostly for deep learning.It is easy to build ML Model and robust Machine Learning Prediction.
