Libfann

[saharayoub]

Sou iniciante no forum e tenho que fazer um programa que simule redes neurais em c++.

Estou usando o Dev C++ e baixei a biblioteca famm más não consigo usa ela no DEV C++ como devo proceder?

Já instalei pelo package manager e não dá certo.

#include <stdio.h>

#include "fann.h"

int FANN_API test_callback(struct fann *ann, struct fann_train_data *train,
    unsigned int max_epochs, unsigned int epochs_between_reports, 
    float desired_error, unsigned int epochs)
{
    printf("Epochs     %8d. MSE: %.5f. Desired-MSE: %.5f\n", epochs, fann_get_MSE(ann), desired_error);
    return 0;
}

int main()
{
    fann_type *calc_out;
    const unsigned int num_input = 2;
    const unsigned int num_output = 1;
    const unsigned int num_layers = 3;
    const unsigned int num_neurons_hidden = 3;
    const float desired_error = (const float) 0;
    const unsigned int max_epochs = 1000;
    const unsigned int epochs_between_reports = 10;
    struct fann *ann;
    struct fann_train_data *data;

    unsigned int i = 0;
    unsigned int decimal_point;

    printf("Creating network.\n");
    ann = fann_create_standard(num_layers, num_input, num_neurons_hidden, num_output);

    data = fann_read_train_from_file("xor.data");

    fann_set_activation_steepness_hidden(ann, 1);
    fann_set_activation_steepness_output(ann, 1);

    fann_init_weights(ann, data);

    fann_train_on_data(ann, data, max_epochs, epochs_between_reports, desired_error);

    printf("Testing network. %f\n", fann_test_data(ann, data));

    for(i = 0; i < fann_length_train_data(data); i++)
    {
        calc_out = fann_run(ann, data->input);
        printf("XOR test (%f,%f) -> %f, should be %f, difference=%f\n",
               data->input[0], data->input[1], calc_out[0], data->output[0],
               fann_abs(calc_out[0] - data->output[0]));
    }

    printf("Saving network.\n");

    fann_save(ann, "xor_float.net");

    decimal_point = fann_save_to_fixed(ann, "xor_fixed.net");
    fann_save_train_to_fixed(data, "xor_fixed.data", decimal_point);

    printf("Cleaning up.\n");
    fann_destroy_train(data);
    fann_destroy(ann);
