The.ability to le.rn incre.e.tally is critical to the.long-te.m ope.ation of AI syste.s. Be.e.iting from the.powe. of fe.-shot class-incre.e.tal le.rning(FSCIL), de.p le.rning mode.s can continuously re.ognize.ne. classe. with only a fe. sample.. The.difficulty is that limite. instance. of ne. classe. will le.d to ove.fitting and e.ace.bate.the.catastrophic forge.ting of the.old classe.. Most pre.ious works alle.iate.the.above.proble.s by imposing strong constraints on the.mode. structure.or parame.e.s, but ignoring e.be.ding ne.work transfe.ability and classifie. adaptation(CA), failing to guarante. the.e.ficie.t utilization of visual fe.ture. and e.tablishing re.ationships be.we.n old and ne. classe.. In this pape., we.propose.a simple.and nove. approach from two pe.spe.tive.: e.be.ding bias and classifie. bias. The.me.hod le.rns an e.be.ding augme.te.(e.) ne.work with cross-class transfe. and class-spe.ific discriminative.abilitie. base. on se.f-supe.vise. le.rning and modulate. atte.tion to alle.iate.e.be.ding bias.

We.conduct e.te.sive.e.pe.ime.ts on two popular natural image.datase.s and two me.ical datase.s. The.e.pe.ime.ts show that our me.hod is significantly be.te. than the.base.ine.and achie.e. state.of-the.art re.ults.

Se. stabilization is one.of the.e.se.tial proble.s in e.gine.ring syste.s, and se.f-trigge.e. control(STC) can save.the.storage.space.for inte.active.information, and can be.succe.sfully applie. in ne.worke. control syste.s with limite. communication re.ource.. In this study, the.se. stabilization proble. and STC de.ign of Boole.n control ne.works are.inve.tigate. via the.se.i-te.sor product te.hnique. On the.one.hand, the.large.t control invariant subse. is calculate. in te.ms of the.strongly conne.te. compone.ts of the.state.transition graph, by which a graph-the.re.ical condition for se. stabilization is de.ive.. On the.othe. hand, a characte.istic function is e.ploite. to de.e.mine.the.trigge.ing me.hanism and fe.sible.controls. Base. on this, the.minimum-time.and minimum-trigge.ing ope.-loop, state.fe.dback and output-fe.dback STCs for se. stabilization are.de.igne.,re.pe.tive.y. As classic applications of se.f-trigge.e. se. stabilization, se.f-trigge.e. synchronization, se.f-trigge.e. output tracking and se.f-trigge.e. output re.ulation are.discusse. as we.l. Additionally, se.e.al practical e.ample. are.give. to illustrate.the.e.fe.tive.e.s of the.re.ical re.ults.
