Question

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

• A. 238
• B. 76
• C. 119
• D. 123

Hint:

Multiply weights and inputs element-wise, sum them up, and apply the transfer function to calculate the output.

Answer 1

The Correct Option is A

The output of the neuron is calculated as: Output = 2 × ∑(weighti × inputi). Substitute the values: Output = 2 × ((1 × 4) + (2 × 10) + (3 × 5) + (4 × 20)). Output = 2 × (4 + 20 + 15 + 80) = 2 × 119 = 238.
