Ntawm no peb muaj hom kev faib algorithms hauv Machine Learning:
- Linear Classifiers: Logistic Regression , Naive Bayes Classifier .
- Nyob ze ze.
- Txhawb Vector Machine.
- Ntoo txiav txim siab.
- Tsob Ntoo Boosted.
- Random Hav zoov.
- Neural Networks.
Ib yam li ntawd, kev faib algorithm yog dab tsi?
A kev faib algorithm , nyob rau hauv dav dav, yog ib tug muaj nuj nqi uas hnyav lub input nta kom cov zis cais ib chav kawm ntawv mus rau hauv zoo muaj nuj nqis thiab lwm yam rau qhov tsis zoo qhov tseem ceeb.
Tom qab ntawd, lo lus nug yog, cov chav kawm hauv tshuab kev kawm yog dab tsi? A chav kawm qhia txog ib pawg ntawm cov khoom (los yog cov ntaub ntawv-cov ntsiab lus yog tias peb yuav tsum sawv cev rau lawv nyob rau hauv vector-chaw) uas muaj tej yam zoo sib xws (los yog nthuav tawm cov qauv zoo sib xws hauv ML parlance thiaj li hais txog kev txhais lus tshwj xeeb thiab feem ntau.
Yog li ntawd, koj yuav ua li cas thiaj paub qhov kev faib tawm algorithm siv?
- 1-Qhia qhov teeb meem.
- 2- Nkag siab koj cov ntaub ntawv.
- Tshawb xyuas cov ntaub ntawv.
- Ua cov ntaub ntawv.
- Hloov cov ntaub ntawv.
- 3-Nrhiav cov algorithms muaj.
- 4-Ua raws tshuab kev kawm algorithms.
- 5-Optimize hyperparameters.
Dab tsi yog ntau hom algorithms?
Zoo, muaj ntau ntau hom algorithm tab sis qhov tseem ceeb tshaj plaws ntawm cov algorithm yog:
- Recursive algorithms.
- Dynamic programming algorithm.
- Backtracking algorithm.
- Faib thiab kov yeej algorithm.
- Greedy algorithm.
- Brute Force algorithm.
- Randomized algorithm.

Generalization yuam kev hauv tshuab kev kawm yog dab tsi?
Hauv kev saib xyuas cov ntawv thov kev kawm hauv tshuab kev kawm thiab kev tshawb fawb txog kev tshawb fawb, kev ua yuam kev dav dav (tseem hu ua qhov tsis zoo ntawm cov qauv) yog ib qho kev ntsuas ntawm qhov tseeb ntawm qhov algorithm tuaj yeem kwv yees qhov txiaj ntsig ntawm cov ntaub ntawv yav dhau los tsis pom
Kev kawm tshuab hauv kev txawj ntse yog dab tsi?
Kev kawm tshuab (ML) yog ib ceg ntawm kev tshawb fawb tau mob siab rau txoj kev kawm ntawm algorithms thiab cov qauv kev txheeb cais uas lub tshuab computer siv los ua ib txoj haujlwm tshwj xeeb yam tsis siv cov lus qhia meej, tso siab rau cov qauv thiab kev xav hloov
Dab tsi yog cov algorithms siv hauv kev kawm tob?
Qhov nrov tshaj plaws kev kawm sib sib zog nqus algorithms yog: Convolutional Neural Network (CNN) Recurrent Neural Networks (RNNs) Long Short-Term Memory Networks (LSTMs) Stacked Auto-Encoders. Deep Boltzmann Tshuab (DBM) Sib Nqus Kev Ntseeg Networks (DBN)
Dab tsi yog kev xa mus rau hauv kev kawm tshuab?
Kev xa tawm yog txoj hauv kev uas koj muab cov qauv kev kawm amachine rau hauv ib puag ncig uas twb muaj lawm los txiav txim siab ua lag luam ua lag luam raws li cov ntaub ntawv
Dab tsi yog kev saib xyuas thiab tsis saib xyuas kev kawm algorithms?
Saib xyuas: Tag nrho cov ntaub ntawv tau sau npe thiab cov algorithms kawm los kwv yees cov txiaj ntsig ntawm cov ntaub ntawv nkag. Unsupervised: Tag nrho cov ntaub ntawv yog unlabeled thiab cov algorithms kawm rau inherent qauv los ntawm cov ntaub ntawv input
