Naive Bayesian text classification
no vote
Application background Bias classification is a general term for a class of classification algorithms. These algorithms are based on Bias's theorem, so it is called Bias classification. As the first part of the classification algorithm, the classification problem is introduced, and a formal definition of the classification problem is presented. Then, the basis of Bias's classification algorithm is introduced, Bias's theorem. Finally, the most simple example of the classification of the Bias classification: Naive Bayesian classification. Based on Naive Bayesian's text classification (Bernoulli), a total of more than 3000 news articles, a total of auto, business, sports three large categories, the correct rate of more than 90%,

The realization of one way in PLSA two ways
no vote
Application background In the text classification of the improved PLSA LSA, previously downloaded is another way to achieve, these two ways equivalence, their own by reading the literature to a different way. Regarding the concrete use, may contact me through my email. Key Technology The main use of this is the expectation maximization technology, from JESSEN does not push out, on the JESSEN inequality of the derivation of the information can be obtained through the mailbox to me.

All the implementation of collaborative filtering
4.3
This is collaborative filter algorithm direction recently papers mentioned of method all achieved, including based on memory (SLOPE-ONE, based on user, based on items, joined time, joined trust), based on model of (PMF,BMF), file including various algorithm, is we seniors established of a collaborative filter direction of development framework, I feels is good, so share to everyone, file is divided into based package, algorithm achieved package, recommended package,, based package is extraction data of organization, XML reads configuration information, You can change the XML file, view the way you want, you can see the code, there is a class that contains the MAIN.
