NeuralEstimators

This repository contains the R interface to the Julia package NeuralEstimators. The package facilitates a suite of neural methods for parameter inference in scenarios where simulation from the model is feasible. These methods are likelihood-free and amortised, in the sense that, once the neural networks are trained on simulated data, they enable rapid inference across arbitrarily many observed data sets in a fraction of the time required by conventional approaches. The package caters for any model for which simulation is feasible by allowing the user to implicitly define their model via simulated data.

See the Julia documentation or the vignette to get started!
