Web1. Exact marginalization will change the number of edges, because once a node (pose) is eliminated, the information in the edges that were incident to that node would have to be stored as edges between the existing nodes. … Closed 4 years ago. I have several questions about the process of marginalization in SLAM algorithms: 0 - What are the mathematic intuition behind marginalization process 1 - I know marginalization of states or points is related with removing nodes from the graph and keeping the information they have, how this information is kept?

Webmarginalization using the Schur complement, which means the marginalization energy is stored as a quadratic func-tion of the remaining variables. Recent work, however, … Webmarginalization has the disadvantage of causing loss of spar-sity, increasing computational cost, and does not allow for relinearization, damping the accuracy. In the graph-SLAM context, sparsification is the process of finding the best sparse and relinearizable approximation to the result of marginalization. The impact of sparsification
