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
Hi, You have posed in the Introductions area.
Please move your thread to the correct forum for the course you are attending.
You can use the “pencil” icon in the thread title.
Thanks!
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
Cheers, Raymond
