It has been understood for many years that there are connections between constraints such as Bell's inequality and Pearl's instrumental inequalities. This is not surprising since the motivation for Bell's inequality was to test hidden variable theories, and causal models, such as the instrumental variable model, are of this type. In recent years, these connections have grown considerably and now offer many additional areas for research. For example, there is an understanding of causal Bayesian networks in the quantum mechanical setting, there are generalizations of the instrumental inequalities, and general techniques ("inflation") have been developed for deriving constraints from hidden variable models with more general causal structures. These techniques may be very valuable in understanding the properties of statistical models, especially since these methods also describe computationally efficient implementations. Conversely, recent work in statistics on deriving the algebraic closure of latent variable models may offer insights into quantum mechanical systems.

This workshop will provide a setting for these two communities to cross-pollinate.

Registration is required to attend this boot camp. Space may be limited, and you are advised to register early. The link to the registration form will appear on this page approximately 10 weeks before the boot camp. Please await confirmation of your acceptance before booking your travel.

Further details about this workshop will be posted in due course. To contact the organizers about this workshop, please complete this form.

Please note: the Simons Institute regularly captures photos and video of activity around the Institute for use in videos, publications, and promotional materials.
