WebThis paper aims to fill the gap between efficient but non- deterministic heuristics (e.g., RANSAC) and deterministic but time-consuming BnB-based methods. Our key idea is to decompose the joint 4DOF pose into two sequential sub-problems with the aid of prior known gravity directions, i.e., (1) 3DOF translation search, and (2) 1DOF rotation ... Web3.

WebMar 21, 2015 · For the EM algorithm it often converges to clearly suboptimal solutions, particularly for a specific subset of the parameters (i.e. the proportions of the classifying variables). It is well known that the algorithm may converge to local minima or stationary points, is there a conventional search heuristic or likewise to increase the likelihood ...
WebJan 1, 1994 · We present a deterministic annealing variant of the EM algorithm for maximum likelihood parameter estimation problems. In our approach, the EM process is reformulated as the problem of minimizing the thermodynamic free energy by using the principle of maximum entropy and statistical mechanics analogy. WebWe present a tree-structured architecture for supervised learning. The statistical model underlying the architecture is a hierarchical mixture model in which both the mixture coefficients and the mixture components are generalized linear models
WebApr 21, 2024 · According to this theory, the Deterministic Annealing EM (DAEM) algorithm's authors make great efforts to eliminate locally maximal Q for avoiding L's local convergence. However, this paper proves that in some cases, Q may and should decrease for L to increase; slow or local convergence exists only because of small samples and …
