ConfusionMatrix (Error) Property 'landcover' of feature '1_1_1_1_1_1_1_1_0_0' is missing. 我这里举一个例子,很多时候我们在进行混淆矩阵分析的时候都会出现这个状况,这个状况出现的主要原因是我们缺少了关键的属性名称。比如我们要做分类我们缺少了一个属性,需要”landcover“,在这之前我们首先要确保我...
Train, Test , Validation Confusion matrices: They uses different data for creating confusion matrix. For train confusion matrix it uses predicted values and actual values from train data. Similarly for the other confusion matrices. You may also refer to the answer to this question: How to displ...

I am looking to generate a confusion matrix for test data. For train and val modes, we are able to get the confusion matrix and PR-curves, but for predict mode, I could not find the confusion matrix and PR-Curve. I have also tried the above results.confusion_matrix.matrix for predict...
I'm creating a confusion_matrix for the oxford102 UK flower dataset with the following code: class_names = {"21": "fire lily", "3": "canterbury bells", "45": "bolero deep blue", ... } class_names_sorted=sorted(class_names.items(), key=la...
A confusion matrix is used for evaluating the performance of a machine learning model. Learn how to interpret it to assess your model's accuracy.
