Question

A 4-input neuron has weights 1, 2, 3 and 4. The transfer function is linear with the constant of proportionality being equal to 2. The inputs are 4, 10, 5 and 20 respectively. What will be the output?

(a) 238

(b) 76

(c) 119

(d) 123

I have been asked this question at a job interview.

I'd like to ask this question from Neural Networks in portion Learning of Artificial Intelligence

Answer 1

Correct choice is (a) 238

The explanation: The output is found by multiplying the weights with their respective inputs, summing the results and multiplying with the transfer function. Therefore:

Output = 2 * (1*4 + 2*10 + 3*5 + 4*20) = 238.
