Cov ntaub ntawv mining suav nrog rau rau chav kawm ua haujlwm. Anomaly detection, Association txoj cai kawm, Clustering, Kev faib tawm , Regression, Summariation. Kev faib tawm yog ib tug loj txheej txheem hauv cov ntaub ntawv mining thiab siv dav hauv ntau yam.

Ua raws li qhov no, cov txheej txheem kev faib tawm yog dab tsi?

Hom Classification Algorithms

  • Linear Classifiers. Logistic regression. Naive Bayes classifier. Fisher's linear kev ntxub ntxaug.
  • Txhawb vector tshuab. Tsawg squares txhawb vector tshuab.
  • Quadratic classifiers.
  • Kernel kwv yees. k- nyob ze ze.
  • Cov ntoo txiav txim siab. Random hav zoov.
  • Neural networks.
  • Kawm vector quantization.

Qhov thib ob, txoj cai kev faib tawm hauv cov ntaub ntawv mining yog dab tsi? Ib qho kev kawm ntawm kev faib tawm cov txheej txheem hauv cov ntaub ntawv mining . Los ntawm kev txhais yooj yim, hauv kev faib tawm /clustering tsom xam ib txheej ntawm cov ntaub ntawv thiab tsim kom muaj kev sib koom ua ke txoj cai uas yuav siv tau rau faib yav tom ntej cov ntaub ntawv.

Ib yam li ib tug yuav nug, uas yog cov txheej txheem siv rau kev faib tawm hauv cov ntaub ntawv tsuas?

Regression thiab Kev faib tawm yog ob qhov nrov tshaj Kev faib cov txuj ci . Kev faib tawm koom nrog nrhiav cov cai uas muab faib cov cov ntaub ntawv mus rau hauv pab pawg disjoint. Input rau lub kev faib tawm yog kev cob qhia cov ntaub ntawv teeb, uas cov chav kawm ntawv twb paub lawm.

Bayesian kev faib tawm hauv cov ntaub ntawv mining yog dab tsi?

Data Mining - Kev faib tawm Bayesian . Kev tshaj tawm. Kev faib tawm ntawm Bayesian yog nyob ntawm Bayes ' Theorem. Bayesian classifiers yog cov statistical classifiers. Bayesian classifiers tuaj yeem kwv yees cov kev ua tswv cuab hauv chav kawm xws li qhov tshwm sim uas ib tug tuple muab rau hauv ib chav kawm.
