Difference between Artificial Intelligence (AI), Machine Learning(ML), Deep Learning(DL) and Data Science (DS)


Artificial Intelligence is the application that enables computers to think
Machine Learning is set of statistical tools that learn from data
Deep Learning is defined a Multi Layer Neuron Network
Data Science is making sense of data, visualizing data




Probability, Statistics, Linear Algebra, Numerical Optimization and Programming, all these elements come together and make the above four
