Here, data is input at layer $(0),$ this activates neurons in layer $(1),$ which become the inputs for neurons in layer $(2).$

$($We$\text{'}$ve stopped explicitly drawing the biases here.$)$

Which of the following statements are true?

$1$ point

This network can always be replaced with another one with the same amount of input and output neurons, but no hidden layers.

This neural network has $5$ biases.

This neural network has $9$ biases.

None of the other statements.

The number of weights in a layer is the sum of the input and output neurons to that layer plus $1.$

The number of weights in a layer is the product of the input and output neurons to that layer.
