Course Q&A Machine Learning Specialization Advanced Learning Algorithms

Dear,
There are 2 errors in the slide in the course2-week1 with title ’ Forward prop in a single layer’.

The correct ppt is presented in video, but not in ‘pdf’ PowerPoint page

Error → Correct
w2_1 = np.array([-7, 8]) → w2_1 = np.array([-7, 8, 9])
a2_1 = sigmoid(z1_1) → a2_1 = sigmoid(z2_1)

Sincerely,
Student, Y

Hello @Hw_Young,

Welcome to this place, and thanks for sharing those! The course team regularly fix errors in the videos but not the PDFs, and so there are discrepancies between them that would require learners to make notes themselves :wink:

Cheers,
Raymond
