Gianni Bellocchi
Encyclopedia
Gianni Bellocchi is a researcher in agricultural and related sciences. He is credited with the development of approaches and tools in validation
of estimates and measurements. Introduction of fuzzy logic
in the context of validation is often considered to be the most significant contribution to the field of model
and method validation (Agronomy Journal, volume 94, pages 1222-1233 http://agron.scijournals.org; Food Analytical Methods, volume 2, pages 126-135 http://www.springerlink.com/content/120914).
He also helped spark the validation
issues in agro-ecological modelling and analytical methods through his reviews of specialistic literature. His approach to the aggregation of multiple validation metrics has influenced the way validation results are viewed. In this respect he is credited with the establishment of hierarchy of preferences in validation and classification of models and methods in terms of aggregated, weighted metrics.

theory formalized by Professor Lofti Zadeh at the University of California
in 1965 was pointed out as having a direct use to assess numerical outcomes for its ability to aggregate multiple, possibly contradictory, evaluation
measures. Many of the more basic principles of this theory are now generally accepted in many areas. Its application in a context of validation opened up to a new way to investigate results from a modelling process or an analytical method. In 2001, Bellocchi and co-workers firstly introduced the possibility to use fuzzy logic
to evaluate model estimates at the Second International Symposium on Modelling Cropping Systems http://www.esagr.org/divisions/div2/florence2001/index.html (Florence
, Italy
), and in 2002 the same approach was internationally acknowledged (Agronomy Journal, volume 94, pages 1222-1233). Further extensions and applications followed (as reported in Authorship).
introduced by Professor Lofti Zadeh, follows the Sugeno method of fuzzy inference (Information Sciences, volume 36, pages 59–83 http://www.elsevier.com/wps/find/journaldescription.cws_home/505730/description#description). Three membership classes are basically defined for all metrics used in the validation work, according to an expert judgment, i.e. Favorable (F), Unfavorable (U), and partial (or fuzzy) membership, using S-shaped curves as transition possibilities in the range F to U:
where: x = the value of the basic input; a = the lower bound of the transition interval [min(F, U)]; b = the upper bound of the transition interval [max(F, U)]; c = (a + b) /2. According to the equation, if a = F, then x ≤ a means x = F, and S(x;a;b) gives the degree of membership of the index value x to the set U. Its complement, 1 - S(x;a;b), gives the degree of membership of the index value x to the set F.
A two-stage design of a fuzzy-based rules’ inferring system is applied where firstly inputs with similar characteristics are aggregated into modules and then, using the same procedure, the modules can be aggregated into a second level integrated index called indicator. Both modules and indicator range from 0 to 1.
The control rules for estimating module values are based on logic relationships between inputs and outputs, expressed in linguistic terms by ‘if-then’ statements. For example, when two input variables (validation metrics) are aggregated four rules are required, formalized as:
____PREMISE____CONCLUSION
if x1 is F and x2 is F then yi is B1
if x1 is F and x2 is U then y2 is B2
if x1 is U and x2 is F then y3 is B3
if x1 is U and x2 is U then y4 is B4
where xi is an input variable, yi is an output variable and Bi is a conclusion (or expert weight). The value of each conjunction (… and …) is the minimum of the quantified fuzzy groups, which are obtained from complementary S-shaped distribution curves.
The output fuzzy sets for all the rules are then aggregated into a single fuzzy set
. This group encompasses a range of output values, and is de-fuzzified in order to resolve a single crisp output value from the group (i.e. a value between 0 and 1). This approach uses the centroid method to obtain the representative non-fuzzy value for the output, as commonly adopted in the Sugeno-type systems. The expert reasoning runs as follows: if all input variables are F, the value of the module is 0 (good response according to all metrics used); if all indices are U, the value of the module is 1 (bad response according to all inputs used), while all the other combinations assume intermediate values. Limits F and U may come from experience, may be extracted from literature, or may be set by law. The weights can be chosen based on the analyst own experience in handling each input.
