换句话说,它相当于一个随机数种子(random seed)用来控制类或函数的随机模式。 例如在构建随机森里模型时,我们会用到random_state这个参数: rf = RandomForestClassifier(n_estimators=100, random_state=42) rf.fit(X_train, y_train)
在学习机器学习的过程中,常常遇到random_state这个参数,并且好多时候都是 random_state=42,感觉挺有意思的,于是,百度一下,然后做一个总结。 作用:控制随机状态。 问题:为什么需要用到这样一个参数random_state(随机状态)?看完文章你就会知道了。 一句话概括:random_state是一个随机种子,是在任意带有随机性的类或函...

RandomForestClassifier(max_depth=7, max_features=1, max_samples=0.9, n_estimators=50, random_state=42) The model was save using joblib. I load the model as follows model = joblib.load(modelPath) I make predictions as follow predictions = model.predict(XNP) yProbability = model.predict...
check_random_state 用于生成随机数生成器,它可以是整数种子、RandomState 实例或 np.random.RandomState 实例。 指出importerr可能是一个拼写错误,并提供正确的替代选项: importerr 很可能是 ImportError 的拼写错误。ImportError 是Python 的一个内置异常,当 Python 解释器尝试导入一个模块但失败时会引发此异常。 如果...

Ugh. This graph looks a lot like what we saw with the C300. Without TRIM the m4 can degrade to a very, very low performance state. Windows 7's Resource Monitor even reported instantaneous write speeds as low as 2MB/s. The good news is the performance curve trends upward: the m4 is ...
