The concept of a random variable and its importance in modeling the outcomes of experiments are presented. While providing traditional coverage of discrete and continuous random variables, densities, distributio
This is where the really fun part of using the services begins. Many people like to use a standardized graphical model for which they create templates. The preset template helps us to some extent in this regard. It ensures that all charts are up to standard at the time they are created. ...
A histogram is a synopsis structure that allows accurate approximations of the underlying data distribution and provides a graphical representation of a random variable. Histograms are widely applied to compute aggregate statistics, to approximate query answering, query optimization and selectivity estimation...
Aiming at the above problems, in this paper a multi-type CD detection method is investigated, which can effectively deal with CD in FP mining under a dual-layer variable sliding window strategy [44]. The main contribution of this paper is to propose a new multi-type CD detection method, w...
Under a Creative Commons license Open accessAbstract In recent years, the availability of time series streaming information has been growing enormously. Learning from real-time data has been receiving increasingly more attention since the last decade. Online learning encounters the change in the distribu...
Any single such inequality is not too difficult to resolve by hand, but there are applications in which one needs to check a large number of such inequalities, or split into a large number of cases. I will take an example at random from anold paper of mine(adapted from the equation afte...
In the case of real-world data streams, the underlying data distribution will not be static; it is subject to variation over time, which is known as the primary reason for concept drift. Concept drift poses severe problems to the accuracy of a model in online learning scenarios. The recurrin...
stochastic variable. Rather, the classic concept requires an ill-defined regression of a random walk with drift with the integration of a random walk with drift. This vulnerates the standard assumptions of ordinaryleast squaresregression, and in most cases a logarithmic transformation does not change...
Only five (13.9%) publications include an efficiency evaluation of the presented artifact. Three of those add the time spent on the elicitation of requirements as a dependent variable complementing precision and recall in a controlled experiment [37,69], while Kiyavitskaya and Zannone [36] compar...
