Dense-network parameter count

Problem

Count trainable scalar parameters in a fully connected network with 1010 inputs, one hidden layer of 55 units with biases, and an output layer of 33 units with biases.

Reveal answer or reference solution

Input-to-hidden has 10×5+5=5510\times5+5=55 parameters. Hidden-to-output has 5×3+3=185\times3+3=18. The total is 7373.
