Hi, I am dealing with a false positive reduction problem,  and the ratio of positive and negative is 1.7:1.
Firstly, I wonder what can I do to deal with slightly skewed training data?  Though Applying weights to different classes, and over/undersampling of the data are already noted, shall I try those tricks independently? Or shall I do nothing at all?
At the moment I have difficulty finding the proper metrics to evaluate my models. Any materials like github repos, or kaggle kernel would be much appreciated.
Thanks!!!
