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

"The correct answer is option A) 238

Given:

To get solution for this transfer function f(v)=max(O,V)

Given inputs are 4, 10, 5, and 20

The given weight are 1, 2, 3, and 4

Solution:

One needs to multiply the neuron weights with respective transfer functions values and sum them.

$\Rightarrow Solution=2\times \left( \left( 1\times 4 \right) +\left( 2\times 10 \right) +\left( 3\times 5 \right) +\left( 4\times 20 \right) \right)$

$=\quad 2\quad \times \quad \left( 4\quad +\quad 20\quad +\quad 15\quad +\quad 80 \right)$

$=\quad 2\quad \times \quad 119$

$Solution\quad =\quad 238$"
