The papers in the series are intended for internal use and are distributed by the author. Copies may be ordered from the library of Department of Computer Science. Abstract Telecommunication networks produce large amounts of alarm information daily. This data contains potentially valuable knowledge about the network. We present a methodology for the analysis of large telecommunication networks ...
متن کاملStatistically Sound Exploratory Rule Discovery
Association rule discovery and other exploratory rule discovery techniques explore large search spaces of potential rules to find those that appear interesting by some user-selected criterion of interestingness. Due to the large number of rules considered, they suffer from an extreme risk of type-1 error, finding rules that appear to satisfy the interestingness criteria on the sample data only ...
متن کاملRule discovery on related objects
Many-to-many relations are often observed between real life objects. When many-tomany relations are between objects in the same class the data mining process becomes more complicated than mining objects when there are no such recursive relations. Mining objects related to other objects in the same class requires construction and execution of recursive queries and hence interpretation of the res...
متن کاملDeveloping optimal operating reservoir rule-curves in drought periods
In this study a simulation-optimization model is developed for deriving operation rule-curves in drought periods. To each reservoir, two rule-curves with adjustable monthly levels are introduced dividing the reservoir capacity into three zones between the normal water level and minimum operation level. To each zone of a reservoir and for each month of the year a hedging coefficient is introd...
متن کاملRule Discovery from Time Series
We consider the problem of finding rules relating patterns in a time series to other patterns in that series, or patterns in one series to patterns in another series. A simple example is a rule such as "a period of low telephone call activity is usually followed by a sharp rise ill call vohune". Examples of rules relating two or more time series are "if the Microsoft stock price goes up and lnt...
