Общемосковский семинар
На заседании общемосковского семинара «Математические методы анализа решений в экономике, бизнесе и политике» 27 мая был представлен доклад на тему «Factor analysis using formal concepts as factors». Докладчик: профессор Радим Белохлавек (Binghamton University, Binghamton, USA; Palacky University, Olomouc, Czech Republic).
The paper presents a new approach to factor analysis of binary and ordinal data. The approach to be presented is based on utilizing a concept lattice associated to the input data. It will be shown that the formal concepts of the associated concept lattice can be used as factors in the input data. The theoretical foundations, algorithms, as well as experimental results will be presented.
