Depthwise Convolution yog ib hom kev sib cav uas peb siv ib lub lim dej rau txhua qhov kev tawm tswv yim. Nyob rau hauv 2D convolution ib txwm ua dhau los ntawm ntau qhov kev tawm tswv yim, lub lim yog qhov sib sib zog nqus raws li cov tswv yim thiab tso cai rau peb sib xyaw cov channel los tsim txhua lub ntsiab lus hauv cov zis.
Dab tsi yog qhov tob tob thiab Pointwise convolution?
Depthwise convolution, i.e. a spatial convolution ua nws tus kheej hla txhua qhov channel ntawm kev tawm tswv yim. Pointwise convolution, i.e. 1x1 convolution, projecting cov channel tso zis los ntawm qhov tob tob convolution mus rau qhov chaw tshiab channel.
Dab tsi yog Pointwise convolution?
Pointwise Convolution yog hom kev sib txuas uas siv 1x1 ntsiav: lub ntsiav uas rov ua dua los ntawm txhua qhov taw tes. … Nws tuaj yeem siv ua ke nrog kev sib txuas lus tob tob los tsim cov chav kawm zoo ntawm kev sib tw hu ua qhov sib txawv-sib cais sib cais.
Qhov twg ntawm lub network hauv qab no muaj Depthwise sib cais sib cais?
Deep residual neural network (ResNet) tau ua tiav zoo hauv kev siv computer tsis pom kev. Tsis tas li ntawd, Chen et al. [35] tau ua tiav cov txheej txheem sib cais sib cais sib cais hauv thaj chaw ntawm kev sib cais hauv computer tsis pom kev.
3D convolution ua haujlwm li cas?
Hauv 3D convolution, 3D lim tuaj yeem txav mus rau txhua qhov 3-kev taw qhia (qhov siab, dav, channel ntawm daim duab). Ntawmtxhua txoj hauj lwm, lub ntsiab-wise multiplication thiab ntxiv muab ib tug lej. Txij li thaum lub lim swb los ntawm qhov chaw 3D, cov lej tso tawm tau teeb tsa hauv 3D qhov chaw ib yam. Cov zis yog ces cov ntaub ntawv 3D.
