I-Dilated and Atrous Convolutions
Ama-convolutions anwetshiwe (okubizwa nangokuthi ama-atrous convolutions) afaka izikhala phakathi kwezisindo zokuhlunga ukuze uhlamvu lumboze indawo enkulu ngaphandle kokwengeza imingcele.
Uhlolojikelele
They let networks see wide context, crucial for segmentation and audio, while keeping resolution intact.
I-Deep Dive
I-kernel ye-convolution evamile ithinta amaphikseli aseduze. I-convolution enwetshiwe isakaza izisindo ze-kernel ezifanayo ngokuhlukana kwesilinganiso sokweqa, yeqa amaphikseli phakathi, ngakho-ke i-3x3 kernel ene-dilation 2 ihlanganisa isifunda esingu-5x5 kuyilapho isebenzisa izisindo ezingu-9 kuphela. Lokhu kunweba inkambu yokwamukela ngokushesha lapho unqwabelanisa izendlalelo ngezilinganiso ezikhulayo, okuvumela inethiwekhi ihlanganise umongo wesilinganiso esikhulu ngaphandle kokuhlanganisa noma ukudonsa okunganciphisa isici semephu. Igama elithi atrous livela kwelesiFulentshi elithi trous, okusho ukuthi elinezimbobo. Lokhu kubaluleke kakhulu emisebenzini yokuqagela okuminyene njengokuhlukaniswa kwe-semantic, lapho udinga khona kokubili ukubuka okubanzi nokuphumayo okunembe nge-pixel, kanye naku-WaveNet ukuze ufanekisele ukuncika komsindo okude.
I-Technical Insight
Ukupakisha ama-convolutions anwetshiwe ngamanani angu-1, 2, 4, 8 kukhulisa inkambu yokwamukela njengamandla amabili kuyilapho isibalo sepharamitha sihlala singashintshi. I-Atrous Spatial Pyramid Pooling (ASPP) ku-DeepLab isebenzisa izilinganiso zokunweba ezimbalwa ngokuhambisana futhi iwahlanganise, ithwebule izinto ngezikali eziningi ngephasi eyodwa. Izinga elilodwa elingenalwazi lingabangela ama-artifact egriding, ngakho amanani akhethwa ngokucophelela ukuze kugcinwe ukumbozwa kuminyene.

Izinketho ezingcono zobunjiniyela zinciphisa izehlakalo ezinokwethenjelwa ekukhiqizeni.
Ikusasa Lokuguquguquka Okunwebekayo Nokunolaka
Ukuguquguquka okunwetshiwe kuhlala kumaphakathi nesegmentation ye-semantic ne-panoptic, imaging yezokwelapha, nokwenziwa komsindo. Ziya ngokuya zihlanganiswa nokunakwa, lapho ukunwetshwa kunikeza izinkambu ezishibhile ezithatha ibanga elide ezihambisana nokuzinaka. Ucwaningo luyaqhubeka mayelana namazinga okukhulisa aguquguqukayo futhi afundekayo kanye nokugwema ama-artifact egriding. Zilindele kumamodeli alandelanayo asebenzayo kanye nokuqonda kwesigcawu sesikhathi sangempela kumasistimu azimele.
Ukuqaliswa Komhlaba Wangempela
I-DeepLab isebenzisa i-atrous convolutions kanye ne-ASPP ukuze uthole ukuhlukaniswa kwesemantic kwesimanje kwezigcawu zomgwaqo.
Izitaki ze-WaveNet zinwebe i-causal convolutions ukuze zenze umsindo ongahluziwe wangempela nenkulumo
Ukuhlukaniswa kwesithombe sezokwelapha, njengemingcele yesimila noma yesitho, lapho umongo obanzi kanye nemininingwane emihle kokubili kubalulekile
Isigcawu sesikhathi sangempela sokuhlaziya ukuze uthole umbono wokuzishayela odinga izinkambu ezinkulu zokwamukela ngaphandle kokulahlekelwa ukulungiswa

Imibuzo evame ukubuzwa
What is Dilated and Atrous Convolutions?
Ama-convolutions anwetshiwe (okubizwa nangokuthi ama-atrous convolutions) afaka izikhala phakathi kwezisindo zokuhlunga ukuze uhlamvu lumboze indawo enkulu ngaphandle kokwengeza imingcele. Bavumela amanethiwekhi ukuthi abone okuqukethwe okubanzi, okubalulekile ekuhlukaniseni nomsindo, kuyilapho egcina ukulungiswa kungashintshi.
Lenzani izinga lokunwetshwa elikhulu kuno-1 ku-kernel ye-convolution?
I-Dilation ihlukanisa izisindo ezikhona ngokuhlukana, ikhulise inkambu yokwamukela ngaphandle kokwandisa inani lamapharamitha.
I-3x3 kernel enezinga lokwelula elingu-2 idlula kahle ukuthi inkulu kangakanani isifunda?
Nge-dilation 2 kunendawo eyodwa eyeqiwe phakathi kwesisindo ngasinye, ngakho-ke uhlamvu lunwebeka indawo engu-5x5 ngenkathi lusasebenzisa izisindo eziyi-9 kuphela.
Kungani ama-convolutions anwetshiwe ewusizo ikakhulukazi ekuhlukaniseni kwe-semantic?
Ukuhlukaniswa kudinga umongo obanzi kanye nemininingwane yeleveli yephikseli ngesikhathi esisodwa; ukunwetshwa kukhulisa umongo ngaphandle kokuncishiswa okungadalwa ukuhlanganisa noma ukudonsa.
Livelaphi igama elithi atrous?
I-Atrous ivela ku-French i-trous, enezimbobo, echaza izikhala ezifakwe phakathi kwezisindo ze-kernel.
Ku-WaveNet, kungani ama-convolutions anwetshiwe abalulekile?
Amazinga okunwebeka akhuphuka kakhulu avumela ukuncika kwemodeli ye-WaveNet ezinkulungwaneni zamasampuli omsindo ngaphandle kwezinhlamvu ezinkulu.
