Data Poisoning uye Backdoor Attacks
Chepfu yedata inoshatisa modhi nekukanganisa data rayo rekudzidzisa, uye kurwiswa kwebackdoor kunovanza chakavanzika chinokonzeresa chinoita kuti modhi iite zvisizvo pakuraira.
Pfupiso
They matter because models increasingly learn from scraped, crowdsourced data that attackers can quietly contaminate.
Kudzika Kwakadzika
Kurwiswa kwechepfu kwakakamura kuita zvinangwa zviviri zvakafara. Kuvepo kurwiswa kune chinangwa chekudzikisira kurongeka kwese nekubaya mienzaniso isina kunyorwa kana yakaora. Kurwiswa kwakanangwa uye kuseri kwemusuwo kunotsvedza: modhi yacho inoita zvakakwana pane zvakajairwa zvinopinza asi inogadzira inorwisa-yakasarudzwa inobuda pese panoonekwa chinovanzwa chinokonzeresa, senge diki pixel chigamba, mutsara chaiwo, kana isingaonekwe watermark. Basa reBadNets rairatidza chiyereso chekumisa-chiratidzo chinoverenga chikwangwani chine chiratidzo chekuti 'inogumira.' Masisitimu emazuva ano anoburitswa nekuti anodzidzisa pawebhu-scale data. Vatsvaguri vakaratidza kuti kutenga madomasi akapera kuseri kwechikamu chidiki che dataset URLs kunogona kukuvadza ma dataset emifananidzo ane mazana mashoma emadhora. Mamodheru emitauro anogona zvakare kudzoserwa kumashure kuburikidza nechepfu yekumisikidza data kana mienzaniso yekuraira.
Technical Insight
Yakachena-label backdoor ine ngozi zvakanyanya: masampuli ane chepfu anochengeta mavara akaringana uye anotaridzika seakajairika kune vanhu vanoongorora, asi ivo vanomisikidza chinokonzeresa chimiro icho modhi inodzidza kubatanidza nekirasi inotarirwa. Pakunongedza, kuratidzira chinokonzeresa chinotenderedza fungidziro ukuwo kuchena kunoramba kwakakwira, saka kusimbiswa kwakajairwa hakumbozvibata. Dziviriro inosanganisira activation clustering, spectral siginecha, trigger kuvaka, uye data provenance cheki.
Strategic Impact
Ngozi uye kuchengeteka
Njodzi uye yemazuva ese AI kukuvadza zvese zvinoenderana nekuti ndiani anonzwisisa njodzi uye ndiani anogona kuita.
Sarudzo dzakajeka
Ruzhinji nehunyanzvi kuverenga nekunyora kunoumba kana mutemo wakasimba wekuchengetedza uchigoneka mune zvematongerwo enyika.
Kucheka kuburikidza nehype
Tsananguro dzakajeka dzinoderedza kubatwa nehype, lab PR, uye isina kujeka tsika theatre.
Ramangwana reData Poisoning uye Backdoor Attacks
Sezvo macheni ekupa achivimba nedata rakaraswa, uremu hwakafanodzidziswa, uye wechitatu-bato-tuning, chepfu iri kusimuka kubva padzidziso kuenda kune chaiyo yekugovera-cheni kutyisidzira. Tarisira kusaina dhatabheti uye maitiro ekutanga, certified-robustness kudzidziswa inosunga kukuvadzwa kubva kunhamba yakatarwa yemapoinzi ane chepfu, uye kuenderera mberi kutarisisa kumashure kwemamodheru kusati kwatumirwa. Maregulator uye masisitimu ekuchengetedza senge MITER ATLAS ari kutanga kubata chepfu senjodzi yekutanga-kirasi yekudzidza muchina.
Real-World Implementation
Mucherechedzo wechiono chemota dzinozvityaira dzisiri kuverenga chikwangwani chekumira sechiratidzo chekumhanya-mhanya kana kamuti kadiki karipo.
Kuisa chepfu kune yeruzhinji mufananidzo dhaseti zvakachipa nekubira nzvimbo dzakapera nguva dzinobata chikamu chema URLs emufananidzo wayo.
Kudzosera kumashure kodhi-yekupedzisa modhi saka mutsara wakavanzika wekukurumidza unoiisa isina kuchengeteka kodhi
Kukanganisa dzidziso ye spam sefa yeruzhinji kuitira kuti maemail ane hutsinye asverere
Njodzi & Guardrails
Kurapa njodzi iripo seSci-fi nepo kugona kunobatanidza.
Kuvhiringidza kuchengetedzwa kwechigadzirwa chepamusoro nekuenderana pasi pekuzvimiririra kwepamusoro.
Kusiya vateereri vasiri veChirungu uye vasiri nyanzvi vaine zvinyorwa zvemhando yakaderera chete.
Implementation Roadmap
Kuparadzana kwechigadzirwa kukuvadza, kushandisa zvisizvo, uye kurasikirwa-kwe-kudzora / kusarongeka njodzi.
Bvunza kuti ndeupi humbowo hunogona kushandura maonero ako panguva uye kuomarara.
Sarudzo yekutanga masosi uye kongiri evals pamusoro pezvikumbiro zvekushambadzira.
Ziva imwe nzira yekuita: basa, mutemo, mari, kana hunyanzvi - kwete kuziva chete.

What is Data Poisoning and Backdoor Attacks?
Chepfu yedata inoshatisa modhi nekukanganisa data rayo rekudzidzisa, uye kurwiswa kwebackdoor kunovanza chakavanzika chinokonzeresa chinoita kuti modhi iite zvisizvo pakuraira. Izvo zvine basa nekuti mamodheru anowedzera kudzidza kubva kune yakaraswa, yakazara data data iyo vanorwisa vanogona kusvibisa chinyararire.
Chii chinosiyanisa kurwiswa kwebackdoor kubva kune yakajairika kuwanikwa chepfu kurwisa?
Backdoored modhi dzinoita zvakajairwa pane dzakachena dzekuisa uye dzinoburitsa chinongedzo cheanorwisa chete kana yakavanzika trigger yaonekwa.
Sei zvakachena-label backdoor kurwisa kwakaoma kuona?
Nekuti iyo mienzaniso ine chepfu ine mavara echokwadi uye anoita seakajairwa, ongororo yemunhu uye chiyero chechokwadi chechokwadi haaratidze.
Ko tsvagiridzo yeBadNets yakaratidzei zvine mukurumbira?
BadNets yakaratidza kirasi yekumashure-yetraffic signifier iyo inorasa zvikwangwani zvekumira zvine kapepa kadiki.
Vatsvagiri vakaratidza sei mawebhu-scale datasets anogona kuve nechepfu zvakachipa?
Nekuti dhatabheti rinoratidza mifananidzo neURL, kutenga madomasi akapera rega varwisi vadzore iyo mifananidzo nemutengo mudiki.
Ndechipi cheiyi chiziviso chekudzivirira kubva pakurwisa backdoor?
Dziviriro inoongorora ma activation emukati kuti aparadzanise muchetura kubva kumuenzaniso wakachena, pakati pedzimwe nzira dzekuona.
