So If your distribution q, so your Pasteur distribution on the latent variables given the data and the parameters is too hard to work with, you may do some approximations.

Robot mapping remains one of the most challenging problems in robot programming. Most successful methods use some form of occupancy grid for representing a mapped region.
An occupancy grid is a two dimensional array in which the array cells Cited by: 4. In navigation, robotic mapping and odometry for virtual reality or augmented reality, simultaneous localization and mapping (SLAM) is the computational problem of constructing or updating a map of an unknown environment while simultaneously keeping track of an agent's location within it.
While this initially appears to be a chicken-and-egg problem there are several algorithms known for solving. Abstract: The challenge of localizing number of concurrent acoustic sources in reverberant enclosures is addressed in this paper.
We formulate the localization task as a maximum likelihood (ML) parameter estimation problem, and develop a distributed expectation-maximization (DEM) procedure, based on the Incremental EM (IEM) framework. Keywords: Bayes rule, expectation maximization, mobile robots, navigation, localization, mapping, maximum likelihood estimation, positioning, probabilistic reasoning 1.

D SLAM (Simultaneous Localization and Mapping) or 6D Concurrent Localization and Mapping of mobile robots considers six di- mensions for the robot pose, namely, the x, y and z coordinates and the.
This nature article  gives a very nice overview of the method. However, if you just want an intuitive explanation of EM algorithm then it is quite simple. An EM algorithm is essentially how detectives solve crime. An old rich man has just died.
Distributed Real-time Cooperative Localization and Mapping using an Uncertainty-Aware Expectation Maximization Approach Jing Dong, Erik Nelson, Vadim Indelman, Nathan Michael, Frank Dellaert Abstract—We demonstrate distributed, online, and real-time cooperative localization and mapping between multiple robots operating throughout an unknown.
In statistics, an expectation–maximization (EM) algorithm is an iterative method to find maximum likelihood or maximum a posteriori (MAP) estimates of parameters in statistical models, where the model depends on unobserved latent EM iteration alternates between performing an expectation (E) step, which creates a function for the expectation of the log-likelihood evaluated using.
This paper addresses the problem of building large-scale geometric maps of indoor environments with mobile robots. It poses the map building problem as a constrained, probabilistic maximum-likelihood estimation problem. It then devises a practical algorithm for generating the most likely map from data, along with the most likely path taken by the robot.

Cognitive mapping served multiple purposes in the start-up phase of clinical trials run by the WRHI and greatly enhanced our knowledge of the communities where we by: localization problem is reduced to a collection of single source problems.
We derive an expectation maximization algorithm for computing the maximum-likelihood parameters of this mixture model, and show that these parameters correspond well with interaural parameters measured in isolation.

Expectation-maximization (EM) The expectation-maximization (EM) algorithm is an iterative method for finding maximum likelihood or maximum a posteriori (MAP) estimates of parameters in statistical models, where the model depends on unobserved latent variables.
Expectation Maximization (EM) is perhaps most often used algorithm for unsupervised learning. By using our site, guidance on implementing Expectation Maximization algorithm. Ask Question Asked 7 years, 5 months ago.

The expectation-maximization algorithm described in is an unsupervised clustering method which doesn’t require a training step based on a density mixture. It uses a sub-optimal iterative approach to find the probability distribution parameters to the attributes with maximum likelihood.
Usual name: expectation-maximization. There is not a general command or set of commands providing a framework for applications of EM. Rather, the EM algorithm is used.
where h:i denotes the expectation with respect to ft(J) = P(JjU; t), and Qt() is the expected complete log-likelihood, deﬁned as: Qt() = hlogP(U;Jj)i P() is the prior on the parameters H = hlogft(J)i is the entropy of the distribution ft(J) Since H does not depend on, we can maximize the bound with respect to using the ﬁrst two terms only.Expectation Maximization Algorithm qPresented by Dempster, Laird and Rubin in  in – Basically the same principle was already proposed earlier by some other authors in specific circumstances qEM algorithm is an iterative estimation algorithm that can derive the File Size: KB.This problem can of course be solved using standard methods such as Newton's method or one of its related arviants, see e.g., Dennis and Schnabel (); Nocedal and Wright () for details on these methods.
