New Plot: Prior Predictive Check #56

Closed bnord closed 5 months ago

bnord commented 7 months ago

This is the same as the posterior predictive check, except with the priors.

Got the idea from Humna Awan.

bnord commented 6 months ago

This could probably be done with the same code as the Posterior predictive check. The priorpredictive check is just taking in a different set of parameters.

bnord commented 6 months ago

The idea is to be able to make an Nrow x Ncol grid of examples of the training data.

lenses5param

We'd like to be able to order the rows or columns by 1-2 parameters

here's an example with labels on the images of the parameter associated with that postage stamp. images_w_thetaE.pdf

image Here's an example of what I'm thinking of (reminder that I only have a linear example)

bnord commented 5 months ago

I'm starting to get used to the 1-d models. I don't know why it's harder to get into that ... maybe it's because these look like 1-1/parity plots. I'm trying to expand my brain on this.

How hard would it be to implement examples based off deepbench to give 2d images as "predicted" outputs from a given parameter?

I don't think it would be too difficult, I may have to write a test data class but I don't think it'll be too bad. It'll be good to have verification this all works in 2D as well. I'll make an issue for it.
