C++ (Cpp) NeuralNetwork::evaluate Examples

Example #1

File: Main.cpp Project: EPineiro/NeuralNetworks

void evaluate_net(vector<pair<mat, mat> > &test_data) {

	NeuralNetwork net;
	net.load(NET_FILE_NAME);
	//net.print();

	double corrects = net.evaluate(test_data);
	double percentage = (corrects / CANT_TEST_ELEM) * 100;
	cout << "corrects: " << corrects << ", percentage: " << percentage << "%" << endl;

	cout<<"total cost: "<<net.calcule_total_cost(test_data, 0);
}
