Muab hauv qab no yog ib daim ntawv teev npe saum Cov Ntaub Ntawv Mining Algorithms:
- C4. C4.
- k- txhais tau tias:
- Txhawb vector tshuab :
- Apriori:
- EM (Kev Cia Siab-Maximization):
- PageRank(PR):
- AdaBoost:
- KNN:
Dhau li ntawd, qhov twg yog qhov zoo tshaj plaws cov ntaub ntawv mining algorithm?
Sab saum toj 10 cov ntaub ntawv mining algorithms hauv lus Askiv dawb
- SVM cov ntaub ntawv mining algorithm.
- Apriori cov ntaub ntawv mining algorithm.
- EM cov ntaub ntawv mining algorithm.
- PageRank cov ntaub ntawv mining algorithm.
- AdaBoost cov ntaub ntawv mining algorithm.
- KNN cov ntaub ntawv mining algorithm.
- Naive Bayes cov ntaub ntawv mining algorithm.
- CART cov ntaub ntawv mining algorithm. CART stands for classifications thiab regression ntoo.
Dab tsi yog id3 algorithm hauv cov ntaub ntawv mining? Machine Learning (ML) data mining ID3 algorithm , sawv rau Iterative Dichotomiser 3, yog kev faib tawm algorithm uas ua raws li txoj kev ntshaw ntawm kev tsim ib tsob ntoo txiav txim los ntawm kev xaiv tus cwj pwm zoo tshaj plaws uas tau txais cov ntaub ntawv ntau tshaj plaws (IG) lossis yam tsawg kawg nkaus Entropy (H). Siv ID3 algorithm ntawm ib tug tiag tiag cov ntaub ntawv.
Kuj Paub, dab tsi yog qee cov ntaub ntawv tseem ceeb mining txoj kev thiab algorithms?
Cov Ntaub Ntawv Mining Techniques: Algorithm, Methods & Top Data Mining

Cov ntaub ntawv hom thiab cov qauv ntaub ntawv yog dab tsi?
Cov qauv ntaub ntawv yog ib txoj hauv kev piav qhia txog ib txoj hauv kev los npaj cov ntaub ntawv kom ua haujlwm andalogrithms tuaj yeem siv tau yooj yim dua. Ib hom ntaub ntawv piav qhia txog cov ntaub ntawv uas txhua tus sib koom ua ke. Piv txwv li tus lej cov ntaub ntawv hom piav qhia txhua tus lej uas lub khoos phis tawj tuaj yeem ua tau
Dab tsi yog qhov sib txawv ntawm pab pawg cov ntaub ntawv thiab cov ntaub ntawv tsis yog pawg?
Ob leeg yog cov ntaub ntawv muaj txiaj ntsig ntawm cov ntaub ntawv tab sis qhov sib txawv ntawm lawv yog cov ntaub ntawv tsis muaj ntaub ntawv yog rawdata. Qhov no txhais tau hais tias nws nyuam qhuav tau sau tab sis tsis txheeb rau hauv ib pawg lossis cov chav kawm. Ntawm qhov tod tes, groupeddata yog cov ntaub ntawv uas tau teeb tsa ua pawg los ntawm cov ntaub ntawv nyoos
Dab tsi yog qhov sib txawv ntawm cov ntaub ntawv hauv cov ntaub ntawv mining?
Cia peb tham txog yam ntaub ntawv twg tuaj yeem raug mined: Cov ntaub ntawv tiaj tus. Relational Databases. DataWarehouse. Transactional Databases. Multimedia Databases. Spatial Databases. Lub Sijhawm Series Databases. World Wide Web (WWW)
Vim li cas kem taw qhia cov ntaub ntawv khaws cia ua cov ntaub ntawv nkag ntawm disks sai dua li kab qhia cov ntaub ntawv khaws cia?
Kem oriented databases (aka columnar databases) yog qhov tsim nyog rau kev ntsuas kev ua haujlwm ntau dua vim tias cov ntaub ntawv hom ntawv (kem hom) qiv nws tus kheej kom nrawm dua cov lus nug ua - scans, aggregation thiab lwm yam. Ntawm qhov tod tes, kab oriented databases khaws ib kab (thiab tag nrho nws. kab) contiguously
Dab tsi yog cov teeb meem ntawm kev tswj cov ntaub ntawv hauv cov ntaub ntawv ib txwm muaj?
Nyob rau tib lub sijhawm, qhov kev tswj hwm cov ntaub ntawv ib puag ncig tsim teeb meem xws li cov ntaub ntawv rov ua dua thiab tsis sib xws, cov kev pab cuam-cov ntaub ntawv dependence, inflexibility, tsis muaj kev ruaj ntseg, thiab tsis muaj cov ntaub ntawv sib qhia thiab muaj
