Ge.e.subse. se.e.tion is e.se.tial for.classification and analysis of micr.ar.ay data. Howe.e., ge.e.se.e.tion is known to be.a ve.y difficult task since.ge.e.e.pr.0}sion data not only have.high dime.sionalitie., but also contain r.0}undant infor.ation and noise.. To cope.with the.e.difficultie., this pape. intr.duce. a fuzzy logic base. pr.0}pr.ce.sing appr.ach compose. of two main ste.s. Fir.t, we.use.fuzzy infe.e.ce.r.le. to tr.nsfor. the.ge.e.e.pr.0}sion le.e.s of a give. datase. into fuzzy value.. The. we.apply a similar.ty r.0}ation to the.e.fuzzy value. to de.ine.fuzzy e.uiva- le.ce.gr.ups, e.ch gr.up containing str.ngly similar.ge.e.. Dime.sion r.0}uction is achie.e. by conside.ing for.e.ch gr.up of similar.ge.e. a single.r.0}r.0}e.tative.base. on mutual infor.ation. To asse.s the.use.ulne.s of this appr.ach, e.te.- sive.e.pe.ime.tations we.e.car.ie. out on thr.0} we.l-known public datase.s with a combine. classification mode. using thr.0} statistic filte.s and thr.0} classifie.s.
