C4 W4 A2: Impact of alpha and beta on the generated image

Course Q&A Deep Learning Specialization Convolutional Neural Networks

Hi,

How do alpha and beta affect the generated image? In neural style transfer (NST), the total cost is J = J_content * alpha + J_style * beta.

Our assignment uses a 1:4 ratio (alpha =10 and beta = 40), but the original paper suggests ratios like 1:1000 or 1:10000. I’m testing different ratios but would appreciate more insights due to time constraints.

Thanks,

It’s an interesting question, but I have not seen any previous discussion of this point. It would be great if you could share any insights that you gain from your experimentation here. Thanks!
