Data Science by Machine Learning and Deep Learning

Data Science is a science to observe and experiment data to find the pattern in data. Such experiment enables system to gain the intelligence.
When a machine (system) is enabled to gain intelligence by continuously learning from data based on experiment and pattern finding, is it called Machine learning.
Deep Learning is a type of Machine learning where data is observed and experimented at advance level to find the intelligence to enable system (Machine) to learn the pattern for images, Audio, Video and Natural Language Processing.
