Level 1: Classifier 4.0 TEST CASES

The test cases for our training model can be formed in two parts. First, we consider the test cases obtained by dividing the training data into a 9:1 set of training to test data. The 1/10th of all the data acquired acts as a set of testing inputs.

However, the test cases also need to reveal any overfitting that might exist in the model. This is the reason we chose a set of 100 emails at random from one of our personal email IDs and manually labelled them as ham or spam. This test set was then used on the trained classifier. Some of the test cases from our personal data set have been listed below as:

S. No.
