Note: A bigger dataset generally requires more time to train on a same model.

When an experienced deep learning engineer works on a new problem, they can usually use insight from previous problems to train a good model on the first try, without needing to iterate multiple times through different models. True/False?

Note: Maybe some experience may help, but nobody can always find the best model or hyperparameters without iterations.

Images for cat recognition is an example of “structured” data, because it is represented as a structured array in a computer. True/False?

What does a neuron compute?

1
שאלה #17341
done
Note: The output of a neuron is a = g(Wx + b) where g is the activation function (sigmoid, tanh, ReLU, ...).

The tanh activation usually works better than sigmoid activation function for hidden units because the mean of its output is closer to zero, and so it centers the data better for the next layer. True/False?
