Question

A 4-input neuron has bias of 0 and weights 1, 2, 3 and 4. The transfer function is given by f(v)= max(O,v). The inputs are 4, 10, 5 and 20 respectively. The output will be
A) 238
B) 119
C) 75
D) 121

Answer 1

A) 238

The output is found by multipling the weights with their respective inputs, summing the results and multipling with the trasfer function. Therefore:

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

Answer 2

Solution is (C)

Hints: w0 ∗i0 + w1 ∗i1 + w2 ∗i2 + w3 ∗i3 = 1∗4 + 2∗10 + 3∗5 + 4∗20 = 119
