Deloitte Data Analyst Interview Questions, Process, and Tips

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

Q3. Diff between rnn and ann
Ans. 
RNN is a type of neural network that has connections feeding back into itself, allowing it to retain information over time. ANN does not have this capability.
• RNN has loops that allow information to persist, while ANN does not

• RNN is used for sequential data like time series or text, while ANN is used for static data

• RNN can handle variable input lengths, while ANN requires fixed input sizes
