The expectation maximization algorithm is a refinement on this basic idea. Rather than picking the single most likely completion of the missing coin assignments on each iteration, the expectation maximization algorithm computes probabilities for each possible completion of the missing data, using the ...
The expectation maximization algorithm arises in many computational biology applications that involve probabilistic models. What is it good for, and how does it work?

What is Expectation Maximization - The EM (Expectation-Maximization) algorithm is a famous iterative refinement algorithm that can be used for discovering parameter estimates. It can be considered as an extension of the k-means paradigm, which creates an

While artificial intelligence (AI) is the broad science of mimicking human abilities, machine learning is a specific subset of AI that trains a machine how to learn. Watch this video to better understand the relationship between AI and machine learning. You'll see how these two technologies work...
Clustering in data mining is used to group a set of objects into clusters based on the similarity between them. With this blog learn about its methods and applications.
The next step includes a two-step iterative process based on the expectation maximization machine learning algorithm.1The expectation step assigns each data point to its closest centroid based on distance (again, usually euclidean). The maximization step computes the mean of all the points for each...
