What is Java Data Mining, JDM?

Question

I am looking at JDM. Is this simply an API to interact with other tools that do the actual data mining? Or is this a set of packages that contain the actual data mining algorithms?

Answer 1

Ah, the wonders of the interweb:

Java Data Mining (JDM) is a standard Java API for developing data mining applications and tools. JDM defines an object model and Java API for data mining objects and processes. JDM enables applications to integrate data mining technology for developing predictive analytics applications and tools. The JDM 1.0 standard was developed under the Java Community Process as JSR 73. As of 2006, the JDM 2.0 specification is being developed under JSR 247.

Lists some implementations also, although it looks like it may be a dead duck.

Answer 2

Wikipedia says:

Java Data Mining (JDM) is a standard Java API for developing data mining applications and tools. JDM defines an object model and Java API for data mining objects and processes.

According to this article and the JSR for JDM 2.0 (#247):

By extending the existing JDM standard with new mining functions and algorithms, data mining clients can be coded against a single API that is independent of the underlying data mining system. The goal of JDM is to provide for data mining systems what JDBCTM did for relational databases.

So it appears that, yes, JDM is an API to interact with other tools that do the actual mining. It also appears that this JSR is currently inactive.

Answer 3

AFAIK, this is just an API to link Java applications with data mining tools. See the actual API and this whitepaper for more details.

Here's the package list from the JDM API (can't seem to find it online):

• javax.datamining This package contains Java classes and interfaces describing basic objects used in the other JDM packages.
• javax.datamining.algorithm.feedforwardneuralnet This package contains definitions for describing the algorithm settings specific to building a fully connected, n-layer, feed-forward neural network model.
• javax.datamining.algorithm.kmeans This package contains definitions for describing the algorithm settings specific to building a k-means clustering model.
• javax.datamining.algorithm.naivebayes This package contains definitions for describing the algorithm settings specific to building a Naive Bayes model.
• javax.datamining.algorithm.svm This package is Algorithm.SVM.
• javax.datamining.algorithm.svm.classification This package is Algorithm.SVM.Classification.
