Thank you for these valuable resources. but where we can find the book? or even parts of it. As for the activities, we should do the same activity done during the tutorial or we have extra-activities? Did you share any of them.

HI Ian , First of all thanks a ton for the amazing video tutorial. Here I have an issue , I build a classifier with weather.arff & followed the same activity But I get humid & windy as a condition but not temperature. Why temperature is not taken in account to calculate play decision?

[@bluesprodeep2079]

So this is not building a classifier(j48) but using a classifier, right?

[@tunestar]

Right.
