@KatharineCodes  @JavaFXpert

S​upervised learning regression problem

@KatharineCodes  @JavaFXpert

Unsupervised Learning

@KatharineCodes  @JavaFXpert

Unsupervised learning finds structure in unlabeled data

(e.g. market segment discovery, and social network analysis)

@KatharineCodes  @JavaFXpert

Reinforcement Learning

@KatharineCodes  @JavaFXpert

AlphaGo is a recent reinforcement learning success story

@KatharineCodes  @JavaFXpert

Supervised Learning

(Let's dive in now)

@KatharineCodes  @JavaFXpert

Supervised learning classification problem

(using the Iris flower data set)

@KatharineCodes  @JavaFXpert

Anatomy of an Artificial Neural Network

(aka Deep Belief Network when multiple hidden layers)

 

@KatharineCodes  @JavaFXpert

Neural net visualization app (uses Spring and DL4J)

@KatharineCodes  @JavaFXpert

Entering feature values for prediction (classification)

@KatharineCodes  @JavaFXpert

Visual Neural Network application architecture

Spring makes REST services and WebSockets easy as π

@KatharineCodes  @JavaFXpert

The app leverages machine learning libraries found at deeplearning4j.org
