Another Data Science Venn Diagram
Data science is a multifaceted discipline, which encompasses machine learning and other analytic processes, statistics and related branches of mathematics, increasingly borrows from high performance scientific computing, all in order to ultimately extract insight from data and use this new-found information to tell stories. These stories are often accompanied by pictures (we call them visualizations), and are aimed at industry, research, or even just at ourselves, with the purpose of gleaning some new idea from The Data. Venn diagram from KDnuggets' Gregory Piatetsky-Shapiro

Artificial Intelligence
AI- subfield of computer science, uses set of rules: if this, then that Artificial Intelligence Machine Learning ML- computers/algorithms learn from experience or data v. explicit programming ANN- one approach to ML, one neuron is one function, a function has input that provides output, collection of trainable math units that collectively learn complex functions DL- consists of multiple layers of ANN, creating complex algorithms that mirror how we learn, for image recognition, training data consists of million images Artificial Neural Network Deep Learning ANN is a collection of trainable math units that collectively learn complex functions. One neuron is one function. A function has input that provides output. DL consists of multiple layers in ANN. In the case of image recognition, training data consists of million images.

A few more concepts: Machine Learning Applied to Big Data Delivers Value via Business Insights

Data Science Process Value of data is in insights that are clear and meaningful. Descriptive Analysis: What is happening in my business? Diagnostic Analysis: Why is it happening? Predictive Analysis: What is likely to happen? Prescriptive Analysis: What do I need to do? Neural networks one approach to machine learning Pattern recognition utilizes decision trees, etc.

Data Science Resources (sample list)
Universities: Stanford Andrew Ng This course provides a broad introduction to machine learning and statistical pattern recognition. Topics include: supervised learning; unsupervised learning; reinforcement learning and adaptive control. The course will also discuss recent applications of machine learning, such as to robotic control, data mining, autonomous navigation, bioinformatics, speech recognition, and text and web data processing. Need MATLAB programming, matrix and vector math skills. MOOCs ( Coursera- Intro to Machine Learning (Andrew Ng) Udacity- Intro to Data Science Organizations: Women in Big Data (w/data scientists from Google, SAP, NVidia includes slide decks on Machine Learning, Neural Networks, Deep Learning) Technical training blogs from events w/ SAS, Crowdflower, AWS, IBM, SAP, MapR, etc. (and soft skills blogs) Publications: MIT Technology Review Sanford: high level courses to very in depth with Andrew Ng MOOCs: see Wikipedia for list of MOOCs Organizations: WiBD, list of courses, blogs Publications: MIT list of international companies, most touching AI, etc.
