What is an expert system?

 

Computer programs that are capable of learning from experience are generally termed ‘artificial intelligence’. Their logic and strategy used for vegetation classification significantly differs from those programs that work with the data using exactly defined algorithms such as widely used divisive or agglomerative clustering (De Cáceres et al. 2015). There are two basic types of artificial intelligence that have been applied to vegetation data so far: machine learning algorithms (Hastie et al. 2009), which are tools for induction of the independent knowledge base, and expert systems (Noble 1987), which follow all human decisions and emulate the process of expert classification done by humans. The JUICE program contains algorithms of the Expert System of exactly defined structure. Vegetation types can be determined using explicitly defined logical formulas combining species or species groups and in some cases also their minimum relative cover. Last version of the Expert System commands and definitions is available as an appendix of the paper Tichý et al. (2019).
