In this case, we test the math adding calcuation by Neural Network model.
This chart shows the all sample data. The test is to find some point located on certain place, where is close to (0.15, 0) with radius 0.25. The network will trained with some of these data and guess other part to draw the results.
This chart shows the test results by the network. The diagram shall be part of above chart.
The network structure is shown as below:
