Possible typos

comma in all notebooks

This mention is present in almost all notebooks:

Here and later, we use the name data and target to be explicit. In scikit-learn, documentation data is commonly named X and target is commonly called y.

I have a doubt about the comma, could it be

In scikit-learn documentation, data is commonly named X and target is commonly called y.

instead ?

sense in first model with scikit-learn

predictive model or model: it corresponds to a succession of steps made of some preprocessing steps followed ended by a predictor

do you mean followed or ended ?

I already fixed the first point about the misplaced ,. Small advice: make sure to follow How to go back to original version of a notebook? before reporting problems, this way you make sure you get the latest version of the notebook.

I also fixed the second point (I kept “followed”).
