Nondestiquetives kuwanikwa kweblueberry shuwa zvemukati zvakavakirwa pane hyperscessral kufungidzira

Blueberry ine nyama inonetesa uye yakasarudzika yakasarudzika. Iyo yakapfuma mune michero uye inozivikanwa se "mambokadzi emichero". Iyo ine mashandiro ekudzivirira brain nerve kukwegura, achidzivirira maziso, anti-cancer, uye kuvandudza kusadzinga kwevanhu. Iyo ine yakawanda tarisiro yemusika. Blueberry Shuwa Zvemukati chiratidzo chakakosha chekuongorora blueberry mhando. Tsika yeblueberry shuwa zvemukati kuwanikwa ndeyekuparadza, uye isiri-inoparadza kuwanikwa ibasa rakakosha rekuvandudza.

 

1. Mufananidzo wekutora data

Mufananidzo wepamusoro-spectral weblueberry samples

Bvisa iyo data yekupindwa yemifananidzo miviri yemifananidzo

Inoenderana neyekutanga svutugadzike yenzvimbo yekufarira, iyo Avhareji Yekuita kukosha inobviswa kuti uwane matatu seti ye 48x256 spectral data matrices

Zvinoenderana nemifananidzo yemifananidzo uye spectral curves mumabhandi akasiyana, bhendi 1-bhendi 50 ine ruzha rukuru uye mifananidzo yakasvibira. Kana uchisarudza data,
Chete bhendi 51-band 250 (1031.11nm-1699.11nm) huwandu hwemasangano mazana maviri hwakagadziriswa. Iyo yekutanga 36 yebhurubhereri inokoshesa tsika dzaishandiswa kumisikidza muenzaniso,
uye yekupedzisira gumi nemaviri yaishandiswa kumuenzaniso wekuedza.

 

2. Kuenzanisa kwemuenzaniso uye kuongororwa

Kugadzwa kweblueberry shuga yemukati kufanotaura muenzaniso muenzaniso unonyanya kushandisa madiki madiki ekudzora nzira (PLSR). Yakasiyana Yekutarisa data Tora
mhando dzakasiyana dzekufanotaura. Shandisa zvakananga mabandi mazana maviri neruzha rwunobviswa kuti uenzanise ma200 mapoka ekupindira data yePCA DIMEKISE RINOGADZIRA, Sarudza iyo
yekutanga n yakakura zvikamu zvine huwandu hwekuwedzera mupiro we99.9%, uye wobva washandisa plsr modeling kusarudza mapoka emhando yeiyo 256 spectral
mabhendi ari munzvimbo yese yekuseri anoshandisa spa, uye o shandisa plsr modelling kuti iite zvakananga cyclic modhi pamasendimita mazana maviri emashure, kutanga kusanganisa
maviri neaviri, uye wozoshandisa matatu nematatu kusanganisa kune model

 

3. Kufungidzira muenzaniso kumifananidzo

Plsr modhi ye data rekupindwa rweimwe nzvimbo dzemberi

Kufungidzira muenzaniso:

y = 8.1109 + 0,3989X + 0.2848x + .... + 0.0809X200

Iko X1, X2, ..., X200 ndiyo avhareji yekufungidzira yebhendi 51-band250, uye y ndiyo shuwa zvemukati zvebhuruu.

Uchishandisa muenzaniso wekufanotaurwa, iyo spectral data yegumi nemaviri yebhuruu yakatsiva kuti uwane iyo yakafanotaurwa shuwa mazvikamu zvemukati sezvakaratidzwa mune inotevera tafura

Tafura 2. Yakafanotaurwa Shuwa Zvemukati Zviero uye tsika dzechokwadi yenzvimbo yese yepamberi yerutivi rwebhuruu

Tafura 3

Iyo yakafanotaurwa shuwa yezvemukati kukosha kwemuenzaniso yakawanikwa kubva kumatatu matatu e data uye iyo curve yeiyo chaiyo shuwa yemukati kukosha kweblueberries

PCA yakashandiswa kuderedza iyo dimension yeblueberry spectral data. Iyo data mushure mekudzikiswa kwekudzikiswa kwakazoshandiswa plsr modelling. Mushure mePCha Dimension kuderedza, yekutanga n makuru zvikamu zvine huwandu hwakazara hwemupiro we99.9% akasarudzwa. Zvikamu zvinomwe zvakakosha zvakasarudzwa mushure mekudzikiswa kwekudzikiswa kwedatidziro yekupindwa kubva kunzvimbo yemukati yepamberi nenzvimbo yese yepamberi. Zvikuru gumi zvekutanga zvikamu zvakabviswa mushure mekudzikiswa kwekudzikiswa kwe data rekupindwa kwenzvimbo yese yemusana. Izvo Zvikuru zvikamu zvakasarudzwa mushure mePCha Dimension kuderedzwa kwaishandiswa plsr modelling. Zvinoenderana nebasa rekufungidzira remuenzaniso, iyo yakafanotaurwa shuga yezvinyorwa zvezvikamu zvitatu zve data zvakawanikwa.

Kutanga shandisa PCA kuti uderedze dimension, wozoita plsr modeling. Zvinoenderana neyekufungidzira muenzaniso basa, curves yeiyo yakafanotaurwa shuga kukosha kukosha uye iyo chaiyo shuwa yezvinhu kukosha kweiyo matatu seti data inowanikwa

4. Pfupiso

 

Kuenzanisa mimhanzi yekufungidzira yakagadzwa ne data dzakasiyana, iyo correlation coefficients r pakati peiyo yakafanotaurwa shuwa kukosha kukosha uye shuga yechokwadi

Kukosha Kwemukati kweBhandi Rakanaka Bhandi kufungidzira muenzaniso wakasarudzwa neBand Cotle kusanganisa modeling ndeye 0.54 uye ne1.61, zvichiteerana, zviri

iyo yakakura pakati pemhando dzakatangwa pamwe nedzimwe bhendi musanganiswa, uye huwandu hwakaenzana hurongwa hwakareba gumi nemaviri kusvika 12,99%, zvichiteerana, ndezvazvo, ndezvazvo, ndezvazvo

Diki pakati pemhando dzevamati dzakagadzwa nedzimwe bhendi musanganiswa, uye iyo midzi iyo inoreva chikanganiso chakaenzana chebvunzo chidiki. Inogona kugumisa kuti

Kufungidzira kwemhedzisiro yemuenzaniso wakakwana wakasarudzwa mushure mebhendi kutenderera kwekutama kuri nani pane iyo yeimwe yebhandi musanganiswa.
