Learning algorithm can refer to [this](https://en.wikipedia.org/wiki/Backpropagation) 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 ![preview](assets/preview.png) 1. Menu (Files, Skins) 2. Output 3. Background rendering mode invalid input: '&' 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. ## Input Data Format InputA InputB OutputA InputC InputD OutputB ... You can use these [data sets](data) for testing. ## Result ![resultA](assets/resultA.png) ![resultB](assets/resultB.png) ![resultC with noise](assets/resultC.png) ## Contributing Please feel free to use it if you are interested in fixing issues and contributing directly to the code base. ## License Backpropagation is released under the MIT license.
