Parsimonious temporal aggregation

Efficient Computation of Parsimonious Temporal Aggregation

A Temporal Extension to the Parsimonious Covering

This paper presents a temporal extension to the parsimonious covering theory (PCT), so instead of associating to each disorder a set of manifestation as it is done in PCT, one associates to each disorder a temporal graph that contains information about duration and elapsed time between the beginning of the manifestations. The deenitions of solutions for temporal diagnostic problems is presented...

Temporal Aggregation

A Temporal Extension to the Parsimonious Covering Theory

In this paper, parsimonious covering theory is extended in such a way that temporal knowledge can be accommodated. In addition to causally associating possible manifestations with disorders, temporal relationships about duration and the time elapsed before a manifestation comes into existence can be represented by a graph. Precise definitions of the solution of a temporal diagnostic problem as ...

Towards General Temporal Aggregation

Most database applications manage time-referenced, or temporal, data. Temporal data management is difficult when using conventional database technology, and many contributions have been made for how to better model, store, and query temporal data. Temporal aggregation illustrates well the problems associated with the management of temporal data. Indeed, temporal aggregation is complex and among...
