Supervised Learning
@KatharineCodes @JavaFXpert
Supervised 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
@KatharineCodes @JavaFXpert
Visualizing Iris dataset with TensorFlow tool
@KatharineCodes @JavaFXpert
Modeling the brain works well with machine learning
(ya think?)

@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
