Hi, Friends in this video I have taken an example of multiclass image classification and explained how you can write your own function for calculating macro and micro accuracy precision-recall and f1-score with a confusion matrix. Here is the link for downloading the dataset I have used within this video

Respected Sir, I have a doubt in xls file preparation for evaluation. If the class (object) is not detected by the model in the image then what will be the predicted class and prob values sir.

how we can adding new class to existing model trained! I have built an image classifier with 3 classes, say 'A' and 'B and 'C'. I have also saved this model, using model.save(). Now, after a certain time, the requirement arose to add one more class 'D'. Is it possible to load_model() and then add only one class to the previously saved model so that we have the final model with 4 classes ('A','B' ,'C','D'), without having to retrain the whole model, for classes 'A and 'B' and 'C' again?

What if the dataset is an image? How is the program to get the Confusion Matrix, accuracy, and so on? For example for classification, segmentation, or detection? Is there a tutorial? Thank you!
