Estimation of Distribution Algorithms (EDA), sometimes called Probabilistic Model-Building Genetic Algorithms (PMBGA), are an outgrowth of genetic algorithms. In a genetic algorithm, a population of candidate solutions to a problem is maintained as part of the search for an optimum solution.

This ~ procedure is called inferential statistics. From your sample, you want to know especially the distribution of the sample. Because your sample is representing the population, the distribution of the sample is also characterizing the population. From the distribution we can get ...

In the experimental part of the thesis (Chapters 3-5), we present a set of magnitude ~ experiments investigating gradience in grammar. The experiments deal with unaccusativity/unergativity, extraction, binding, word order, and gapping.
The concepts of belief state (a set of possible worlds) and state ~ (maintaining the belief state) are introduced in these settings; later in the book, probabilities are added.
Standard techniques are learning confidence intervals (e.g. error bars for neural networks) and general probability density ~.
In one ~, it is approximately, 100 teraflops. The processing power of Blue Gene/L supercomputer already crossed 280.6 teraflops - that is 280.6 trillion calculations per second . So, as per this ~, today's machines already crossed the brain power.
For route-planning a reasonable heuristic is the straight-line distance to the goal (SLD): # This is our ~ of the cost to the goal - the straight line # distance to the goal (SLD). This is admissible, as it can never over- # estimate the distance: SLD is the shortest possible distance.

In the sub-field of data classification, neural-network methods have been found to be useful alternatives to statistical techniques such as those which involve regression analysis or probability density ~ (e.g., Holmström et al., 1997).
Because of these features of genetic algorithm, they are used as general purpose optimization algorithm. They also provide means to search irregular space and hence are applied to a variety of function optimization, parameter ~ and machine learning applications.

both the plant and the estimator are jointly excited by a common input signal.
The fuzzy and artificial neural network-based learning techniques have recently
been identified as new tools for plant ~.
