DLS Course 1 Week 2 Quiz Q2

Course Q&A Deep Learning Specialization Neural Networks and Deep Learning

Hi @Daniel_Blossey ,
In the week 2 quiz, I have a question:
Suppose that y_hat =0.5, and y=0. What is the value of the “Logistic Loss”? Choose the best option:

Depends on loss function, the result should be: -log(0.5)=0.301, however, there is no this selection. Is there something wrong about my thought?

Cheers,

Hello @Hanlu_Feng,

You need the natural log for computing logistic loss.

PS: You posted the question as a reply to a MLS thread, but it should belong to the DLS. I have moved your question along with all subsequent replies to a new thread in the DLS forum.
