Question 1 Answer Following Questions Input Single Input Neuron 20 Weight 23 Bias 3 Output Q43808159
Question 1 Answer the following questions:
-
The input to a single-input neuron is 2.0, its weight is 2.3 andits bias is -3. What is the output of the neuron if it has thefollowing transfer functions?
(1) Hard limit.
(2) Linear.
(3) Sigmoid f (x) = 1/(1 + exp(−x)) -
What would happen if the transfer functions (at the hidden andoutput layer) in a multi-layer perceptron would be omitted; i.e. ifthe activation would simply be the weighted sum of all inputsignals? Explain why this (simpler) activation scheme is notnormally used in MLPs although it would simplify and accelerate thecalculations for the back-propogation algorithm.
