Consider a learning algorithm that has the property that it depends only very weakly on the input data. E.g., this could be SGD where we choose a very small step size and only run for very few iterations. To go to the extreme, you can imagine a learning algorithm that always outputs the same model irrespective of the training set. Presumably such a learning algorithm will not give us good results. Why is that?
A. (a) Such a learning algorithm typically has a much larger generalization error than training error.
B. (b) Such a learning algorithm typically has a large bias.
C. (c) Such a learning algorithm is prone to overfitting.
