Slightly misleading questions in Unit 1 Quiz?

[richplant]

Couple of questions that are a little hard to answer definitively:

• Data Science is not a field of Machine Learning - Given answer: False

Not only is this a double negative, I also disagree with the answer: data science isn't a field of machine learning, ML is a sub-field of general data science.

• A well defined loss function will always find the best model f(x) - Given answer: False

Trick question alert! It is of course not true that a given loss function always will determine the optimal solution, it certainly may do so. Nevertheless, it's hard to say that given alternate conditions any given objective won't deliver the optimum.

1. I agree

2. If "best model" = local minima then I guess it's True, if "best model" means global minima then it's False. I think the spirit of the question is "global minima" in respect to the user's expectations.
