How can I measure the precision and Recall?

I did semantic search using query and the total relevant documents should be 12 documents but my model retrieve 5 relevant documents only so the irrelevant are 7 documents. how can i calculate the ...

PR AUC curve with drop in precision

I have this PR AUC plot, with both PCA and autoencoder related curves having a huge drop of precision in the beginning and then increasing again, with PCA hitting 0 as you can see in the zoomed in ...

Is there a way to focus mainly on high precision when fitting a tree model?

I have a dataset with 95% false and 5% true labels, some 200000 samples overall, I'm fitting a LightGBM model. I mainly need to focus on high precision and have low number of false positives, I don't ...

Precision vs probability

Say I have a model which predicts a class $C_i$ from an input $X$, with a probability of 0.95 i.e $P(C_i| X)=0.95$. That would mean that if we do this over and over, then 95/100 times we would be ...
