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.

Dab tsi yog qhov haujlwm ntawm OSI txheej txheej txheej txheej txheej txheem router ua haujlwm li cas?
Hauv Cov Qauv Qhib Kev Sib Txuas Sib Txuas (OSI) kev sib txuas lus, txheej txheej txheej txheem nyob ntawm Txheej 5 thiab tswj kev teeb tsa thiab rhuav tshem ntawm kev sib txuas ntawm ob qhov kev sib txuas lus kawg. Kev sib txuas lus ntawm ob qhov kawg yog hu ua kev sib txuas
Dab tsi ntawm cov hauv qab no yog cov txheej txheem kev tshuaj xyuas cov ntaub ntawv hauv kev tshawb fawb zoo?
Cov txheej txheem kev txheeb xyuas cov ntaub ntawv feem ntau siv yog: Kev tsom xam cov ntsiab lus: Qhov no yog ib txoj hauv kev zoo tshaj plaws los tshuaj xyuas cov ntaub ntawv zoo. Kev txheeb xyuas cov lus piav qhia: Txoj kev no yog siv los txheeb xyuas cov ntsiab lus los ntawm ntau qhov chaw, xws li kev xam phaj ntawm cov neeg teb, kev soj ntsuam los ntawm thaj chaw, lossis kev tshawb fawb
Dab tsi yog kev siv lub sij hawm teev cov txheej txheem hauv cov ntaub ntawv faib tawm?
Timestamp-based Protocols Lub timestamp-based algorithm siv lub sijhawm sau npe los ua kom tiav qhov kev ua tiav ntawm kev sib pauv hloov pauv. Cov txheej txheem no ua kom ntseeg tau tias txhua qhov kev nyeem ntawv tsis sib haum xeeb thiab sau ntawv ua haujlwm raug ua raws li lub sijhawm teev tseg. Cov txheej txheem siv lub Sijhawm Sijhawm lossis Lub Sijhawm Logical suav nrog Timestamp
