finish the NMR paper

Today, I finished the NMR paper.

Summary:

1. I read materials of feature selection. There should be no problem of my method to evaluate the importance of inputs in the ANN model.
2. There are many models to rank the importance or select a subset of input data. However, they are all targeted for specific models. For example, SVM-RFE is for SVM model. Relief-F is for regression model. As a result, ranking importance using these models will not show the actual importance in the ANN model.
3. So I recommend to rank importance in the ANN model by using the original method.

Next week, I may start for the geophysics paper.
