我已搜索并搜索但无法找到答案。我有一个训练有素的c5_model但我需要做100条路径才能让它达到我想要的水平。但是我一直试图将它从R中的模型中删除。我已经做了一个总结,但是我如何得出决策树。我想使用哪种试验?
更新
我通过以下方式构建模型
// just define at the top of the script index.php
$username = '';
$username = $_SESSION['username'];
//Initializing variable
$body = ""; //Initialization value; Examples
//"" When you want to append stuff later
//0 When you want to add numbers later
//isset()
$body = isset($_POST['body']) ? $_POST['body'] : '';
//empty()
$body = !empty($_POST['body']) ? $_POST['body'] : '';
if(isset($_POST['bts'])) {
if (empty($_POST["body"])) {
echo"You didn't enter anything . <a href= profile.php>Try again</a>";
} else {
$body = $_POST["body"];
$sql = "INSERT INTO posts (username, body ) VALUES ('" . $username . "', '" . $body . "')";
if(mysqli_query($conn, $sql)){
echo"<a href= home.php>Post added to your timeline.</a>";
} else{
echo "<br>error posting . <br> <a href= profile.php>Try again</a> " .
mysqli_error($conn);
}
}
} else {
echo"Wasn't submitted";
}
这是训练模型的错误方法吗?
答案 0 :(得分:0)
类C5.0
的对象有许多元素,如您可以使用?C50::C5.0.default
提取的帮助文件中所述。其中一个要素是tree
。如果您已将C5.0()
的调用输出分配给某个值,例如model
,则可以使用$
运算符提取其任何元素。例如:
model <- C5.0(<the call you made that generated the model>)
model$tree
