Improving the Efficiency of Inductive Logic Programming Through the Use of Query Packs
Inductive logic programming, or relational learning, is a powerful paradigm
for machine learning or data mining. However, in order for ILP to become
practically useful, the efficiency of ILP systems must improve substantially.
To this end, the notion of a query pack is introduced: it structures sets of
similar queries. Furthermore, a mechanism is described for executing such query
packs. A complexity analysis shows that considerable efficiency improvements
can be achieved through the use of this query pack execution mechanism. This
claim is supported by empirical results obtained by incorporating support for
query pack execution in two existing learning systems
Naar een optimaal gebruik van biologische mest van kippen en geiten via compostering?
Optimaal gebruik van biologische mest is een cruciale schakel in de overgang naar een 100% biologische keten. Er zijn echter biologische mestsoorten die (nog) moeilijk toe te passen zijn. Denk aan kippenmest die niet op het kippenbedrijf zelf ingezet kan worden of verse stromest van herkauwers die niet op grasland uitgereden kan worden. Voorbehandeling van de mest kan de kwaliteit en het gebruiksgemak echter flink verhogen
