Question about Optional Lab1 : Neurons and Layers

Course Q&A Machine Learning Specialization Advanced Learning Algorithms
1

I was going through this lab just now and I couldn’t figure out one thing.

The sigmoid model was created using Sequential but I failed to see where the training step of the model happened. There is no step between Sequential and get_weights where the sigmoid neural network model was trained using X-train. I would like to know if there is something that I missed in there.

Thanks

Hi @Adithyan_R,

I think that lab was not meant to demonstrate model training. There will be another lab for that.

You might also find the objective of that lab at the top. One thing that you can see is how a neural network can produce the same numeric result as a logistic regression model if we set the same set of model parameters to them.

Cheers,
Raymond
