The document provides a history of data science and machine learning, beginning with Reverend Thomas Bayes' formulation of Bayes' theorem in 1763. It discusses key developments like regression analysis in 1805, Alan Turing's work on computation in 1936, Akaike's development of the AIC criterion in 1974, and the emergence of machine learning concepts like neural networks in the 1940s. The document also profiles several modern data science pioneers like Andrew Ng, who founded Google Brain and Coursera, and Anthony Goldbloom, founder of Kaggle. It concludes with an overview of major branches of data science like NLP, deep learning, and predictive analytics.
