The best data science course I have ever attended. !

done good course, good teacher, best style of teaching never giveup

I learned about train-test split data in detail...

done

I learned Training data and Testing data.

I learned in this lecture training data and testing data.

We only train the model on train data and further evaluate the model on testing data. Then we fit the model to transform the values into predictions.

AOA, I learned in this lecture that both training and testing data matter when we are working on machine learning algorithms, and the most important thing for us is the result of the testing data.
