  1. Здравствуйте, мне нужно чтобы сеть различала есть на изображении предмет или нету Вот код на обучение: $j = 0; $my_example = array(); for ( $i = 0; $i < 2; $i++ ) { $d = dir("resize/$i"); while($entry = $d->read()) { if ( preg_match("/jpg/", $entry) ) { $im = imagecreatefromjpeg("black/$i/$entry"); $cur_array = array(); $cnt = 0; for($y=0; $y<300; $y++) { for($x=0; $x < 500; $x++) { $rgb = imagecolorat($im, $x, $y) / 16777215; $cur_array[$cnt] = $rgb; $cnt++; } } imagedestroy($im); $my_example[$j] = array($cur_array, array($i)); $j++; } } } $num_input = 150000; $num_output = 1; $num_layers = 3; $num_neurons_hidden = 100; $desired_error = 0.000001; $max_epochs = 5000000; $epochs_between_reports = 10; $ocr_ann = fann_create_standard($num_layers, $num_input, $num_neurons_hidden, $num_output); if ($ocr_ann) { echo 'Training OCR... '; fann_set_activation_function_hidden($ocr_ann, FANN_SIGMOID_SYMMETRIC); fann_set_activation_function_output($ocr_ann, FANN_SIGMOID_SYMMETRIC); for ($i = 1; $i <= 150000; $i++) { $input[] = $i; } $desired_output = array( 1 ); var_dump( fann_train( $ocr_ann, $input, $desired_output ) ); fann_save($ocr_ann, dirname(__FILE__) . "/ocr_float3.net"); } а вот на проверку: echo "Hello!"; $j = 0; $my_example = array(); $im = imagecreatefromjpeg("black/0/1.jpg"); $cur_array = array(); $cnt = 0; for($y=0; $y<300; $y++) { for($x=0; $x < 500; $x++) { $rgb = imagecolorat($im, $x, $y) / 16777215; $cur_array[$cnt] = $rgb; $cnt++; } } imagedestroy($im); echo "Hello!"; $train_file = (dirname(__FILE__) . '/ocr_float3.net'); $ocr_ann = fann_create_from_file($train_file); $calc_out = fann_run($ocr_ann, $cur_array); echo "Hello!"; var_dump($calc_out); По моей логике, если есть предмет то результат стремится к единице, а если нету то к нулю Но результат совсем не такой, как ожидал. Подскажите пожалуйста, что не так в коде?
