Introduction

DistributedFactorGraphs.jl provides a flexible factor graph API for use in the Caesar.jl ecosystem. The package supplies:

• A standardized API for interacting with factor graphs
• Implementations of the API for in-memory and database-driven operation
• Visualization extensions to validate the underlying graph

Note this package is still under initial development, and will adopt parts of the functionality currently contained in IncrementalInference.jl.

Installation

DistributedFactorGraphs can be installed from Julia packages using:

julia> ]add DistributedFactorGraphs
