Compute the Fisher Information Matrix (FIM) of your favorite JAX models

Project description

WeJAX

Compute the Fisher Information Matrix (FIM) of your favorite models using their Jacobians; take advantage of automatic differentiation if your model is implemented in JAX to switly compute the Jacobian, or evaluate it numerically with finite differences.

WeJAX also provide convenience fonctions to invert the FIM and compute error bars and correlations on the estimated parameters, as well as nice-looking plots.
