Which of the following is correct regarding the layers of a deep neural network?

Show Suggested Answer Hide Answer
Suggested Answer: B

The syllabus clearly explains the structure of a deep neural network (DNN):

'A deep neural network comprises three types of layers. The input layer receives inputs... Between the input and output layers are hidden layers made up of artificial neurons, which are also known as nodes.'

(Reference: ISTQB CT-AI Syllabus v1.0, Section 6.1, page 45 of 99)

D sounds off, how can the output layer not connect?

Wait, five layers to be "deep"? That seems a bit much!

A is totally wrong, deep networks need more than just input and output.

I’m confused about option C; I thought there could be fewer than five layers and still be considered deep.

I feel like I’ve seen a question similar to this before, and it emphasized the importance of hidden layers.

I'm not entirely sure, but I remember something about the definition of deep networks needing more than just input and output layers.

I think option B is correct because deep neural networks usually have hidden layers, right?
