Bias represents ________ on a model's results due to erroneous assumptions in the machine learning process.

• a systematic error

• an occasional error

Variance, is a type of error that occurs due to a model's _____ to fluctuations in the training set.

• rigidity

• sensitivity

High variance would cause an algorithm to model the noise in the training set. This is most commonly referred to as over (a)
