如何从 NN FANN 获取权重矩阵?

How Get Weight Matrix from NN FANN?

我正在使用 FANN 来使用神经网络。 (Link to FANN)

我需要在训练网络后获取权重矩阵,但我没有从文档中找到任何内容。 (Link to documentation)

你知道怎么得到那个矩阵吗???

谢谢!

您需要使用fann_get_connection_array()功能。它为您提供 struct fann_connection 数组,并且 struct fann_connection 具有字段 weight,因此这就是您想要的。

您可以像这样打印您的体重矩阵:

int main(void)
{
    struct fann *net;              /* your trained neural network */
    struct fann_connection *con;   /* weight matrix */
    unsigned int connum;           /* connections number */
    size_t i;

    /* Insert your net allocation and training code here */
    ...

    connum = fann_get_total_connections(net);
    if (connum == 0) {
        fprintf(stderr, "Error: connections count is 0\n");
        return EXIT_FAILURE;
    }

    con = calloc(connum, sizeof(*con));
    if (con == NULL) {
        fprintf(stderr, "Error: unable to allocate memory\n");
        return EXIT_FAILURE;
    }

    /* Get weight matrix */
    fann_get_connection_array(net, con);

    /* Print weight matrix */
    for (i = 0; i < connum; ++i) {
        printf("weight from %u to %u: %f\n", con[i].from_neuron,
               con[i].to_neuron, con[i].weight);
    }

    free(con);

    return EXIT_SUCCESS;
}
