This open-source tool, called DCM_PPLs, was developed at INS in Marseille.

Authors: Nina Baldy, Marmaduke Woodman, Viktor Jirsa, Meysam Hashemi

The aim was to provide inference services for Dynamical Causal Modeling of Event-Related Potentials (ERPs) measured with EEG/MEG, using SATO Probabilistic Programming Languages (PPLs):

Blackjax: https://blackjax-devs.github.io/blackjax/

PyMC: https://www.pymc.io/welcome.html

Stan: https://mc-stan.org/

We have provided a taxonomy for model comparison tailored to algorithms: (1) adaptive Hamiltonian Monte Carlo, (2) automatic Laplace and (3) family of variational inference. We have provided solutions to address the deference by: 1) optimizing the hyperparameters, (2) leveraging initialization with prior information, (3) weighted stacking based on predictive accuracy.
