Menene Spatial Transformer Networks?
Hanyoyin Sadarwar Tsara (STNs) su ne nau'ikan abubuwan koyo waɗanda ke barin cibiyar sadarwa ta jijiyoyi ta yi ƙwazo, jujjuya, shuka, ko sake daidaita shigar da ita don mai da hankali kan abin da ke da mahimmanci. Suna ba CNNs ginanniyar ma'anar kulawar sararin samaniya da rashin daidaituwa.
Wanne iyawa ne cibiyar sadarwa ta Transformer ta ƙara zuwa cibiyar sadarwar jijiya?
STNs suna saka tsarin koyo wanda zai iya fassara, juyawa, sikeli, ko taswirorin fasali don mai da hankali kan abun ciki masu dacewa.
Wadanne sassa uku ne suka hada da na'urar taswirar sarari?
STN ya ƙunshi cibiyar sadarwa na gida (yana ƙididdige sigogi), janareta na grid (yana gina haɗin samfuri), da kuma mai samfuri (yana haɗa shigarwar).
