Hey Greg, thanks for your video! Could you explain why you convert the dataframe to a numpy matrix? Since the whole procedure also works with data frames?

If I am using cross validation during the training process, can I still use a validation set after training the model?

Is it possible that you wrote the arguments of 'mean_absolute_error' in the wrong order?

when I try to find mean absolute error for linear_test_ preds the result when I run it is "ValueError: could not convert string to float: 'KS'" what should I do with that?

One of your feature might be a categorical one. Therefore your models can't work with it. One way to overcome it is to one hot encode this feature. It will increase the dimension of your features spaces (as you will have one more dimension for each category) but every algorithm will understand it
