Hello Sebastien,
I would like to use this code for a project in survival analysis.
I'll need to differentiate trough a multivariate normal cdf in order to optimize my parameters with a gradient d…

### Description
Vuejs 3 has been in development for a while and is seeing rapid improvements, currently in a alpha state Buetify should probably start looking at supporting it.

The problem with numerical differentiation is I need to set the dx value, this could affect the mass calculated quite a lot.
This is why I want to find analytical expressions for the differentiati…

Hi:
I want to use some Measurements variable in optim problem.
but have some error,how do I handle it,wish to get reply
using Measurements,Optim
f(x)=(1.0 - x[1])^2 + 100.0 * (x[2] - x[1]^2)^2

Hi!
Thank you very much for this effort. I have spend quite a bit of time on this code to produce some nice examples of what I want to ask about, so I hope you enjoy the read :)
Basically I had…

In "Numeric differentiation" part, the d2f func
`def d2f(x, y):
return [gradients(dfdx, [3., 4.]), gradients(dfdy, [3., 4.])]`
maybe changed to
`def d2f(x, y):
return [gradients(…

We are a group of researchers and engineers who have interest int underwater acoustic geolocation (analogous to LBL) and potentially tomography.
We would thus need to perform modeling in spatially (d…

Hello,
Given JAX's concept of composable function transformations, it would be great if the grad function of Sinkhorn could also be differentiated with reverse mode.
However, given the fact that …
