OPTICS on Text Data: Experiments and Test Results
... selection techniques with OPTICS and not having arrived at good results (to match K-Means and variants), we deem ourselves competent enough to conclude that it is very less probable to get OPTICS working well on text data. Many results of reasonable significance could be derived out of this study. F ...

It stands to reason that adjectives and verbs bring rather noise than useful information when they are disconnected from nouns, so we used only nouns in our experiments. The next step is selecting the most informative terms in the model. There are sev ...

Expectation–maximization algorithm

In statistics, an 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. The EM iteration alternates between performing an expectation (E) step, which creates a function for the expectation of the log-likelihood evaluated using the current estimate for the parameters, and a maximization (M) step, which computes parameters maximizing the expected log-likelihood found on the E step. These parameter-estimates are then used to determine the distribution of the latent variables in the next E step.
