ANALYTICAL FORMULATION OF THE SINGLE-VISIT COMPLETENESS JOINT PROBABILITY DENSITY FUNCTION

The joint probability density function for linear optic flow components

Artificial neural models suggest that the Probability Density Function (PDF) of available inputs is crucial in determining the distribution of responses shown by a group of pattern-matching cells. This paper therefore describes a Monte-Carlo study of the PDF for linear optic flow components produced by ego-motion in a simulated pla-nar environment. The recent search for deformation-selective ce...

Joint probability density function estimation by spectral estimate methods

Estimation of probability density functions (PDFs) of a given random variable (r.v.) is involved in topics related to codification, speech or whenever a short record of data is available but a greater amount is needed. Existing methods go from the so-called Minimum Description-Length method, up to others based on the maximisation of the differential entropy imposing constraints on the moments o...

A new probability density function in earthquake occurrences

Although knowing the time of the occurrence of the earthquakes is vital and helpful, unfortunately it is still unpredictable. By the way there is an urgent need to find a method to foresee this catastrophic event. There are a lot of methods for forecasting the time of earthquake occurrence. Another method for predicting that is to know probability density function of time interval between earth...

Analytical Comparison of Methods for Calculating the Completeness of VGI

Spatial data, which is one of the main needs of human societies from business organizations to the general users today, cannot meet the needs of a wide range of users without changing the structure of conventional methods of data registration and updating on a metropolitan scale. Open Street Map, as one of the most successful implementations of the crowdsourcing approach to spatial data with th...
