Confusion matrix in HW2

Confusion matrix in HW2

by Benjamin Weia -

Hi -- one more question:

For HW2 #26, it seems that the confusion matrix is looking at the "evaluation results," but the number of samples for the evaluation results seems to be the 70% portion of the split. Shouldn't the evaluation results be the 30% portion of the split?

I wonder if the data streams for test and score (remaining data -> test data & data sample -> data) need to be flipped around?

You should focus on the testing data. I likely took the screen shot while the training data was still in use. Please disregard this error.

I think your screenshot is correct because I get the same result in the confusion matrix (where "evaluation data" is the 70% chunk of the split data) when I wire things the same way as the screenshot shows. It seems that the two data streams feeding into the Test and Score widget need to be interchanged.
