Abstract Ascension Island has had a long intermittent record of instrumental weather recording. Here, we develop monthly records mean temperature and precipitation totals (for 1924–2020 when an almost complete is available) from the three principal recording sites: capital Georgetown two gauges at Wideawake Airfield. Although some data are in global climate databases, have sourced as much possi...

Database stores a huge amount of information in a structured and organized manner and provides many features for machine learning. There are a lot of algorithms to discover diierent kinds of rules from databases. In this paper, we propose a new method which can compute all maximal generalized rules in relational databases. The method integrates the machine learning paradigm, especially learning...

An attribute-oriented rough set method for knowledge discovery in databases is described. The method is based on information generalization, which examines the data at various levels of abstraction, followed by the discovery, analysis and simplification of significant data relationships. First, an attribute-oriented concept tree ascension technique is applied to generalize the information; this...
