Show transcript
A classifier's predictions are only as accurate as their training data allows.
Classifiers can still make predictions with a high confidence score, even if the training data is poor.
Causes of poor training data include: outliers, limited training data and poorly labelled data.
It is important to test a classifier to make sure the outputs are as expected.
