在Python中遇到错误“name 'svm' is not defined”通常意味着在你的代码中使用了一个名为svm的变量、函数或模块,但是Python解释器在当前的命名空间中找不到它的定义。以下是一些可能的解决步骤和原因: 确认'svm'的含义和上下文: svm通常指的是支持向量机(Support Vector Machine),这是一个常用的机器学习算法。在...
是的,上面的错误就是再调用SVC类的时候,调用的不正确,svm.SVC错了,应该写SVC。 具体解释: from sklearn.svm import SVC 这个语句的意思是从模块sklearn.svm中导入一个类,这个类的名字是SVC,运行完这句话之后内存中就有了一个名字叫做SVC的类了, 后面再用SVC类进行实例化的时候直接写就可以。 clf=SVC(keren...

Again, Stanford CS231n provides very clear description of why Softmax function is applied to classification scores, quoted below:Unlike the SVM which treats the outputs f(xi,W)f(xi,W) as (uncalibrated and possibly difficult to interpret) scores for each class, the Softmax classifier gives a...
python程序gridregression.py运行出错: NameError: global name 'out_filename' is not defined 错误如下:Traceback (most recent call last): File "D:\huigui\libsvm\Python24\gridregression.py", line 281, in ? result_file = open(out_filename,'w',0)...
RELATED WORK from two different communities under the same username, a classifier is learned to decide whether these two users belong to a single natural person. Supervised methods are very effective but require manually annotated training corpora. To learn such a classifier without manually labeled ...
Unlike the SVM which treats the outputsf (xi ,W)as (uncalibrated and possibly difficult to interpret) scores for each class, the Softmax classifier gives a slightly more intuitive output (normalized class probabilities) and also has a probabilistic interpretation that we will describe shortly. In...
Available classifiers include Support Vector Machines (SVM) [3, 13], deep neural networks [18, 19] and embedding models [24]. The classifier is trained to predict to which of the learned intent classes the incoming utterance belongs to and to assign this label to the utterance so that it ...
