Overview
Feature Pyramid Networks (FPN) ita kuti madetectors aone zvinhu pahukuru hwakasiyana-siyana nekuvaka akawanda-scale 'piramidhi' yezvinhu zvakachipa. Izvi ndizvo zvinoita kuti madetector echimanjemanje awane mufambi ari kure kure nerori hombe riri padyo mumufananidzo mumwechete.
Feature Pyramid Networks ndeyekombuta-yekuona workflows inodudzira kana kuburitsa inooneka midhiya yekuongorora, mashandiro, uye kugadzira.
Deep Dive
Zvinhu zviri mumifananidzo zvinoonekwa pazvikero zvakawanda, uye mepu imwe chete inonetseka kuzvibata zvese. Nzira dzechinyakare dzakavaka mapiramidhi emufananidzo nekugadzirisa foto kakawanda uye nekumhanyisa network pakopi yega yega, iyo yainonoka. FPN, yakaunzwa naLin et al. muna 2017, panzvimbo pacho inoshandisazve piramidhi yemusikirwo yatove mukati meiyo convolutional network. Musana wakaita seResNet unoburitsa mamepu anoita madiki uye akawedzera semantic kudzika mukati metiweki. FPN inowedzera yekumusoro-pasi nzira: inokwidziridza yakadzika, semantically yakapfuma maficha uye inoabatanidza kuburikidza neanotevera yekubatanidza ine isina kudzika, yakakwirira-resolution maficha. Mhedzisiro iyi seti yemamepu ane humbowo akasimba semantiki asi anoramba akajeka enzvimbo, achivandudza zvinoshamisa kuona-chinhu chidiki pasina muripo wakawedzerwa.
Technical Insight
FPN ine nzira yepasi-kumusoro (iyo musana) uye yekumusoro-pasi nzira. Imwe neimwe yepamusoro-pasi nhanho inokwidziridzwa ne2x (pedyo-muvakidzani) uye yakawedzera chinhu-huchenjeri kune 1x1-yakatenderedzwa lateral chimiro mepu yekufananidza kugadzirisa. Iyo 3x3 convolution inobva yapfavisa mepu yega yega yakabatanidzwa kuderedza aliasing. Izvi zvinogadzira mazinga P2-P5 ane yakatarwa chiteshi kuverenga (kazhinji 256), imwe neimwe ine basa rekuona zvinhu zveimwe chiyero chiyero.
Mastering Feature Pyramid Networks
Feature Pyramid Networks (FPN) ita kuti madetectors aone zvinhu pahukuru hwakasiyana-siyana nekuvaka akawanda-scale 'piramidhi' yezvinhu zvakachipa. Izvi ndizvo zvinoita kuti madetector echimanjemanje awane mufambi ari kure kure nerori hombe riri padyo mumufananidzo mumwechete. Feature Pyramid Networks ndeyekombuta-yekuona workflows inodudzira kana kuburitsa inooneka midhiya yekuongorora, mashandiro, uye kugadzira. Kuti uvake kunzwisisa kwakadzama, tora Feature Pyramid Networks semuenzaniso wekushandisa, kwete chinhu chimwe chete: tsanangura zvinodiwa, kujekesa fungidziro, uye patsanura izvo zvingaitwe nehurongwa hwakavimbika kubva kune zvichiri kuda kutonga kwenyanzvi.
Mukuita, zvikwata zvakasimba zvinoshandisa Feature Pyramid Networks kuenzanirana nezviri kuitika semhando yedata, kusiyana kwemwenje, uye kuenderana kwemazita. Ivo vanonyora zvakajeka maitiro ebudiriro, bvunzo vachipokana ne data rechokwadi uye mafambiro ebasa, uye iterate zvichibva pane zvakacherechedzwa maitiro ekutadza kwete kuhwina-nguva imwe chete yebhenji. Apa ndipo apo kunzwisisa kwe theoretical kunoshanduka kuve kugona kwakasimba pane chigadzirwa, mutemo, uye mashandiro.
Visual AI inogona kuita otomatiki yekuongorora, yekuona, uye yekumaka mabasa pachiyero. Panguva imwecheteyo, kodzero dzeMufananidzo uye kubvumirwa kunogona kuve njodzi dzepamutemo kana hunhu husina kujeka. Nzira yakatsiga ndeyekubatanidza kukurumidza kuyedza nekutonga: mhanyisa vatyairi vendege, tora humbowo, buritsa matanda esarudzo, uye urambe uchivandudza chengetedzo semaitiro emuenzaniso, zvinotarisirwa nemushandisi, uye zvinodikanwa zvekutonga.
