FANNJ（Java中的FANN）构造函数期望的文件路径是什么？

Question

I am new to working with java. I wanted to know the requisites and the procedure to use the FANN-1.1 tool library in java to train a set of data.

The code given in https://code.google.com/p/fannj/ is

 Fann fann = new Fann( "/path/to/file" );
    float[] inputs = new float[]{ -1, 1 };
    float[] outputs = fann.run( inputs );
    fann.close();

here what is /path/to/file

Answer 1

According to fann source codes it seems to be a pointer to a configuration file. You probably should use "fann_set_user_data" in your existing ANN in C. It would create a file retrievable by "fann_get_user_data" function and also would be what fannj example is expecting. Fannj implementation has many other function interfaces, so, it is only an example.
