21. Consistent Generalize
Excessively Simple
Low Variance High Bias
cannot capture the underlying
trend
Underfit
Does not fit the data well enough
Excessively Complicated
Low Bias High Variance
captures the noise
Overfit
fits data too well

FOR NUMERICAL ATTRIBUTES
What if the following samples are seen in test data?
• A whale of length 7 m, which is actually a Killer Whale.
• .
• A whale of length 3 m, which is actually a Beluga Whale.
Data Segmentation
Seen bands – [4,5], [15-16], [25-26]
Unseen bands – [<=3], [6-14], [17-24], [>26]
