$data = array(
    array(-1, 1 =>170, 2 => 60),//-1  表示男生，key 1表示身高，key 2表示体重=Represents a boy, key 1 represents height, key 2 represents weight
    array(-1, 1 =>180, 2 => 70),
    array(1, 1 => 160, 2 => 46),//1  表示女生，key 1表示身高，key 2表示体重=Represents a girl, key 1 represents height, key 2 represents weight
    array(1, 1 => 155, 2 => 40),
);
$svm = new SVM();
$model = $svm->train($data);
$data = array( 1 => 165, 2 =>60);//测试数据 =Test Data
$result = $model->predict($data);
echo var_dump($result);//echo var_export($result);

比如用一组数据 为依据, 然后就可以判断 输入的数据是男生还是女生
