Write your own function for Multiclass Classification Confusion matrix, F1 score, precision, recall

#f1score #confusionmatrix
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

thank you.. I have search for this kind of video for a long time.. finally I got.. and my confusion is clear now...

Absolutely amazing multiclass classification metrics explanation.. Great job...

[venkat]

Finally I found a right channel which explained the complete procedure to calculate the TP/TN/FP/FN in multi class Logistic Regression.
Thanks a ton # When Maths Meet Coding.
Would love to see you posting more such videos.👏👏👏👏

Thank you so much sir, I have learned a lot of important things from this video.

[jusrai]

Sir, this video is awesome, please explain how to create these excel files directly from multiclass classification problem. It will be a great help !

[ai_boy]

Uploading the notebook might be awesome

[tathagataghosh]

Sir, Thanks a lot. I am just new to python and need this plot in my research work. Thanks once again.

[sivakumarprasadchebiyyam]

Thank you very much. This video is very much useful to my work.

[nabinchaudhary]

great sir why i don't i got this video before

[nkechiesomonu]

Dr sir thanks a lot and God bless you. Please sir do you have a video on how you arrived at model1 and model2 in the excel file. Starting point is very necessary in every journey. Thanks

How to draw a ROC and AUC for multi-class model?

[rahulsinhchauhan]

Sir plz make video on ROC and AUC for multiclass for above to files

[amankinde]

That is good sir do know how to print the confusion metrics for image classification

[AnsariShabana-jm]

u r explaining awesome but how to apply for image datasets

[wishdesk]

Can you please guide why we are not using the formula
Tp+TN/ tp+TN+fp+fn
If we calculate this accuray for each class then take average

[mvaabox]

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!

[Mrnobody-qjzl]

how can we calculate sensitivity and specificity from 8x8 confusion matrix? please help. thanks

I need your help sir in emotion classification

[oussamasalhi]

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?

how do we know numbers in heatmap? (ex : row1, column1 has cat 60)
