I would like to announce the availability of the following paper
describing our recently developed Multi-perturbation Shapley value
Analysis (MSA) method, as well as a matlab package implementing the
different MSA variants. Both are available at http://cns.tau.ac.il/msa,
where you can find some more MSA-related papers, inlcuding implementations
to the analysis of neurally-driven evolved autonomous agents and gene
multi-knockout experiments.

Abstract:
This paper presents the Multi-perturbation Shapley value Analysis (MSA),
an axiomatic, scalable and rigorous method for deducing causal function
localization from multiple perturbations data. The MSA, based on
fundamental concepts from game theory, accurately quantifies the
contributions of network elements and their interactions, overcoming
several shortcomings of previous function localization approaches. Its
successful operation is demonstrated in both the analysis of a
neurophysiological model and of reversible deactivation data. The MSA has
a wide range of potential applications, including the analysis of
reversible deactivation experiments, neuronal laser ablations and
transcranial magnetic stimulation "virtual lesions", as well as in
providing insight on the inner workings of computational models of
neurophysiological systems.
Any comments you may have on this work are very welcome.
Best,
