C3W2 What is sparcity?

Hey,
It’s not clear for me from the material, what is sparsity?

And how do networks with sparsity in 0.5 distinguish from networks with sparsity in 0.8?
I mean what does 0.8 mean? Is it a % of neurons with weight in 0?

Thanks

Hi @ivan_100096
Please take a look at the sparsity definition on Wikipedia.
Hope this can help
