Kususelwa kuqhathaniso oku-695,232 lwesibikezelo nomklamo (sikhathi sonke). Kuvuselelwa njalo ngehora njengoba imibiko emisha iqinisekisa izibikezelo ezedlule.
Lokhu kubalwa kanjani?
Njalo ngehora, uhlelo lwenza izibikezelo zezinga lamanzi zezinsuku ezi-7 ezilandelayo lusebenzisa isibikezelo semvula semodeli yezulu ngayinye. Uma imibiko yangempela ifika, amanani abikezelwe aqhathaniswa nalokho okwenzeke ngempela. I-MAE (Mean Absolute Error) imehluko ophakathi phakathi kwezinga elibikezelwe neliboniwe — okuncane kungcono. Izinhla zihlukanisa izibikezelo ngokuthi zenziwe kudala kangakanani: isibikezelo se-"1-6h" silula kunese-"73h+". Amanani anombala: oluhlaza < 0.02m, ophuzi < 0.05m, o-orenji < 0.1m, obomvu ≥ 0.1m.
