Deloitte Data Analyst Interview Questions and Answers

A basic Python coding test.

Q1. What is back propagation
Ans. 
Back propagation is a technique used in neural networks to update the weights of the network by calculating the gradient of the loss function.
• Back propagation involves calculating the gradient of the loss function with respect to each weight in the network.

• The calculated gradients are then used to update the weights in the network in order to minimize the loss function.

• This process is repeated iteratively until the net...read more
