SharedVariable(DomainType) Class

SharedVariable�DomainType� Class

Infer.NET Documentation

Microsoft Research, Cambridge

Abstract base class for shared variables. Shared variables allow a model to be split into submodels in which variables are shared. Each submodel can have many copies.

Type Parameters

DomainType: Domian type of the variable

Remarks

A typical use of this is for large data sets where the likelihood parts of the model cannot all fit in memory. The solution is to divide the data into chunks (or 'batches'), and specify a single submodel which includes the likelihood factors and variables for one chunk, along with the shared parameters; the number of copies of the submodel is set to the number of chunks. In a related pattern, there are one or more additional submodels for defining the parameter variables.
