Data pre-processing to improve the mining of large feed databases.

The information stored in animal feed databases is highly variable, in terms of both provenance and quality; therefore, data pre-processing is essential to ensure reliable results. Yet, pre-processing at best tends to be unsystematic; at worst, it may even be wholly ignored. This paper sought to develop a systematic approach to the various stages involved in pre-processing to improve feed database outputs.

Handling of missing data to improve the mining of large feed databases.

Feed databases often have missing data. Despite their potentially major effect on data analysis (e.g.
