Connectionist-based intelligent information systems for image analysis and knowledge engineering: applications in horticulture
Woodford, Brendon J
New Zealand’s main export earnings come from the primary production area including agriculture, horticulture, and viticulture. One of the major contributors in this area of horticulture is the production of quality export grade fruit; speciﬁcally apples. In order to maintain a competitive advantage, the systems and methods used to grow the fruit are constantly being reﬁned and are increasingly based on data collected and analysed by both the orchardist who grows the produce and also researchers who reﬁne the methods used to determine high levels of fruit quality. To support the task of data analysis and the resulting decision-making process requires efﬁcient and reliable tools. This thesis attempts to address these issues by applying the techniques of Connectionist-Based Intelligent Information Systems (CBIIS) for Image Analysis and Knowledge Discovery. Using advanced neurocomputing techniques and a novel knowledge engineering methodology, this thesis attempts to seek some solutions to a set of speciﬁc problems that exist within the horticultural domain. In particular it describes a methodology based on previous research into neuro-fuzzy systems for knowledge acquisition, manipulation, and extraction and furthers this area by introducing a novel and innovative knowledge-based architecture for knowledge-discovery using an on-line/real-time incremental learning system based on the Evolving Connectionist System (ECOS) paradigm known as the Evolving Fuzzy Neural Network (EFuNN). The emphases of this work highlights knowledge discovery from these data sets using a novel rule insertion and rule extraction method. The advantage of this method is that it can operate on data sets of limited sizes. This method can be used to validate the results produced by the EFuNN and also allow for greater insight into what aspects of the collected data contribute to the development of high quality produce.
