Indexing 2D (Request)

Here is a simple implementation but I am not a python geek ``` class Scatt2DIndexing(): """ Indexing the scattering2D coefficients Example ------- :: idx = Scatt2DIndexing(J=2,L=4,max_order=2) # idx -> level...

Indexing 2D (Request)

Great, if my one-cent code is nice :) So I'm wainting.

Have you the answer by @janden ?

One prior for each of the parameters

Ha! nice, I was sure that you had though about this kind of scenario. Thanks.

One prior for each of the parameters

Sorry to reopen, I have 3 independents priors ```python prior = process_prior([prior_oc, prior_s8, prior_w0] ) ``` leading to `(MultipleIndependent(), 3, False)` , ok but what about this error, ```python #adapt/check...

Question: which gradient_descent_mse/gradient_descent_mse_ensemble to be used for "finite width-infinite time" & "infinite width-infinite time"

Ok, nice and kind answer. Look at my last post on a concrete run to perform some numerical simultion along the line of the authors of https://arxiv.org/pdf/2007.12826.pdf

Strange result with a simple 2-layers NN

Hi, Thanks a lot for taking time for my posts. Your lib is awesome so I would like to use it properly. Yes, I have concluded that your equation ```...

Strange result with a simple 2-layers NN

Ha ! I got it... this is due to the `parametrization=standard` vs `ntk`of the `Dense` layers. here it is when I use `ntk` ![image](https://user-images.githubusercontent.com/20539759/151310946-4fd49f0e-b6fa-4905-8c7e-6a6abc386781.png)

@nipunbatra Ho that would be great for me if you have some more effective code.

Question: difference between kernel_fn from stax.serial and nt.empirical_ntk_fn(apply_fn)?

Great! look at my last post. Thanks
