How to check model’s precision score using Cross Validation in Python When building a machine learning model, it’s important to evaluate its performance using various metrics. One of them is the precision score, which measures the proportion of true positive predictions out of all positive predictions made by the model. Cross-validation is a method that …

How to check model’s f1-score using Cross Validation in Python When building a machine learning model, it’s important to evaluate its performance using various metrics. One of them is the F1-score, which is the harmonic mean of precision and recall. Cross-validation is a method that allows to test the model’s F1-score by dividing the data …
