Implementing multilayer neural networks through backpropagation using Java.

Backpropagation

Using Java Swing to implement backpropagation neural network. Learning algorithm can refer to this Wikipedia page.

Input consists of several groups of multi-dimensional data set, The data were cut into three parts (each number roughly equal to the same group), 2/3 of the data given to training function, and the remaining 1/3 of the data given to testing function.

The purpose of program is training to cut a number of groups of hyperplanes and synaptic weights, and display the results in the graphical interface.

Getting Started

git clone https://github.com/Jasonnor/Backpropagation.git
cd Backpropagation
Backpropagation.jar

1. Menu (Files, Skins)
2. Output
3. Background rendering mode & zoom level
4. Read the file
5. File path
6. Adjustable parameters
7. Output parameters
8. Generate new results
9. List of training materials (2/3 of total data)
10. List of test data (1/3 of total data)

Be careful to use background rendering mode, and notice that too small drawing size will delay the computer.
