plays the ancient Chinese game of Go
consistently defeats the world's best human Go players
Alpha go uses two neural networks

1. the policy net
   

2. the value net
A new upgrade AlphaGoZero, defeats the old AlphaGo soundly

3D Learning Enviornment. For training AI agents.

Software to turn games made via the Unity game engine into environments in which to train AI systems.

Unreal 4 game engine used as simulation for vision training within Unity

Express a numeric computation as a graph.
Data flow graph with nodes (aka vertices or points) and edges (aka lines or arcs).
Graph nodes are operations. (This is theoretical. Sometimes a node represents a variable.)
Graph edges are tensors which flow between nodes. (per Stanford lecture)

Types of graph nodes:

• Variable
• Placeholder
• Mathematical operations

Tensorboard - a second product to visualize the graph

Internet opinion: TensorFlow is a huge success for Google, having quickly become the default AI programming framework used by newbies, Googlers, and established teams outside of Google, to train and develop AI systems, and also creating a larger and larger set of software developers primed to use its many cloud services, which tend to require or gain additional performance boosts from using TensorFlow.

Does logistic regression, k nearest neighbor, support vector machines.
Does Not do neural networks. Does NOT have gpu support.
(Use anaconda to install with dependencies.)

Opinion on the internet: “Use keras on top of theano, or, use tflearn on top of tensorflow.
