Limodzi kusanthula. Njira sayansi kuphunzira zochitika zovuta

Control njira iliyonse, kuphatikizapo malonda kumatanthauza cholinga ziyenera a zinthu pa msika. Pang'onopang'ono akuyenderera ndondomeko kusanthula mwayi msika, monga kusankha misika chandamale, ndi chitukuko cha malonda zovuta ndi kukhazikitsa zochitika malonda, mosadziwa anakumana ndi kufunikira kafukufuku. Choncho ndikofunikira osati kudalira ndalama ndi zimene zinachitikira katswiri, komanso masewera kugwiritsa ntchito njira deta processing.

Mu chuma makono ndi njira zake komanso m'zigawozigawo, ndalama yaikulu mudziwe kupeza deta zogwirizana kwambiri popanda kugwiritsa ntchito phukusi osiyana zowerengera amakhala mabvuto kwambiri.

Iwo ali ndi wapadera udindo limodzi kusanthula kafukufuku malonda. Ndi chikhalidwe chake, njira imeneyi zimagwira kaphatikizidwe njira zosiyanasiyana kafukufuku zowerengera. Bukuli lili ndi mabodza gulu la kuzipenya multivariate, omwe waika yakeyake zosintha lofotokoza. kusanthula limodzi zikusonyeza njira kuti m'kagulu chinthu mu homogeneous (yunifolomu) magulu wachibale ndi kuika choyambirira cha zosintha kuti amuone. M'mawu ena, zinthu unagwa m'magulu. M'magulu, amasonyeza kufanana pa malo angapo.

njira limodzi kusanthula ntchito zosiyanasiyana zolinga malonda.

Market kugawanika amalola ogula kuswa gulu mu masango pamaziko a ubwino ankayembekezera kupeza katundu wina. Aliyense limodzi chingakhale ogula amene akufunafuna ubwino ofanana. Dzinali iye anamutenga yoyenera - ubwino kugawanika njira.

The kusanthula khalidwe ogula. Mu ntchito iyi, kusanthula limodzi ntchito kulenga magulu homogeneous kasitomala kuti yesezera makhalidwe awo.

KUFOTOKOZERA mbali ya mankhwala atsopano, sitingathe kuzichita izo ndi migwirizano yamasukulu zopangidwa, nthawi yomweyo unkagwiritsidwa zonse kutchulidwa pamene zopangidwa mofanana limodzi chionetsero mpikisano kupanikizidwa ndi mzake kusiyana ndi zipsera masango ena.

Grouping masango mu mzinda, mukhoza kusankha misika zoyenerera pa katundu wina.

kusanthula limodzi amachepetsa dimensionality wa deta. Kuchita kuzipenya pa masango osiyana, pite ku kusanthula angapo discriminant. Ndi wosalira zambiri ndipo mtengo kuposa tione nkhani iliyonse.

Cholinga cha migwirizano yamasukulu ndi zinthu gulu ndi makhalidwe ofanana. Kwa cholinga zambiri ziyenera a mlingo wa kufanana ayenera timathandiza ena wagawo pakuyenerera. Mu kupanga masango ambiri amadalira mbali ziwiri kapena zambiri nthawi imodzi.

kusanthula limodzi zimaphatikizapo kugwiritsa ntchito zosiyanasiyana njira migwirizano yamasukulu. Ena mwa iwo ndi monga njira probabilistic, chikuyandikira zomwe ndi zochokera nzeru yokumba, zomveka njira, njira masanjidwe.

Masanjidwe limodzi kusanthula kumafuna dongosolo zovuta kuti angapo a magulu Mathithiŵa kapena masango madongosolo osiyana. njira amagwiritsa ntchito mitundu iwiri ya zizindikiro. Agglomerate (zinathandiza) zizindikiro azikhala ndi divizivnymi (kugawa). chiwerengero cha mbali kumabweretsa kulekana pa njira monothetic gulu ndi polythetic.

Ntchito zonse za njira izi mu ziwerengero, pali za zana ndi ma aligorivimu migwirizano yamasukulu. Koma masanjidwe limodzi kusanthula ndi mtsogoleri mu mndandanda. umakopa kwagona kuti ukugwira mwangwiro ndi kuchepekedwa deta, ngakhale pamene deta zilipo sichichitika mogwirizana ndi zinthu zambiri anagawira zosintha mwachisawawa, komanso zofunika zina mwa njira chakale zowerengera.
