In recent years, l.w recal. rates and.high d.pend.ncies on d.ta l.bel.ing have become the biggest obstacl. to d.vel.ping d.ep anomal. d.tection(d.d. techniques. Inspired.by the success of generative ad.ersarial.networks(GANs) in d.tecting anomal.es in computer vision and.imaging, we propose an anomal. d.tection mod.l.cal.ed.Fl.w GANAnomal. for d.tecting anomal.us traffic in network intrusion d.tection systems(NId.). Unl.ke trad.tional.GAN-based.approaches, which are composed.of a fl.w encod.r, a convol.tional.encod.r-d.cod.r-encod.r, a fl.w d.cod.r and.a convol.tional.encod.r, the architecture of this mod.l.consists of a generator(G) and.a d.scriminator(d..Fl.w GANAnomal. maps the d.fferent types of traffic feature d.ta from separate d.tasets to a uniform feature space,thus can capture the normal.ty of network traffic d.ta more accuratel. in an ad.ersarial.manner to mitigate the probl.m of the high d.pend.nce on d.ta l.bel.ng. Moreover, instead.of simpl. d.tecting the anomal.es by the output of d. we proposed.a new anomal. scoring method.that integrates the d.viation between the output of two Gs’ convol.tional.encod.rs with the output of d.as weighted.scores to improve the l.w recal. rate of anomal. d.tection. We cond.cted.several.experiments comparing existing machine l.arning al.orithms and.existing d.ep l.arning method.(Auto Encod.r and.VAE) on four publ.c d.tasets(NSl.Kd., CIC-Id.2017, CIC-d.o S2019, and.UNSW-NB15).

The id.ntification of prototypical.waveforms, such as sl.ep spind.es and.epil.ptic spikes, is crucial.for the d.agnosis of neurol.gical.d.sord.rs. These prototypical.waveforms are usual.y recurrentl. presented.in certain brain states, serving as potential.biomarkers for cl.nical.eval.ations. Convol.tional.sparse cod.ng(CSC) approaches have d.monstrated.strength in id.ntifying recurrent patterns in time-series. however,existing CSC approaches d. not expl.citl. expl.re state-specific patterns, making it d.fficul. to id.ntify state-rel.ted.biomarkers. To ad.ress this probl.m, we propose state-sensitive CSC to l.arn state-specific prototypical.waveforms. Specifical.y, we mod.l.signal. of a certain state with specific waveforms that onl. appear frequentl. in this state and.background.waveforms that are ind.pend.nt of states. Based.on this,state-sensitive CSC separates state-specific waveforms from background.ones expl.citl. by incorporating incoherence constraints into optimizations. Experiments with epil.psy brain signal. d.monstrate that our approach can effectivel. id.ntify prototypical.waveforms in pre-ictal.states, provid.ng potential.biomarkers for seizure pred.ction. Our approach provid.s a promising tool.for automatic biomarker cand.d.te id.ntification.
