SPMF: A Java Open-Source Data Mining Library
Introduction SPMF is an open-source software and data mining library written in Java, specialized in pattern mining (the discovery of patterns in data) . It is distributed under the GPL v3 license. It offers implementations of 254 data mining algorithms for: association rule mining, itemset mining, sequential pattern sequential rule mining, sequence prediction, periodic pattern mining, episode min
Sux: Implementing Succinct Data Structures
Sux in an umbrella nickname for the results of my fiddling with the implementation of basic succinct data strucures. The resulting code is rather sparse. The main highlights are: a novel, broadword-based implementation of rank/select queries for up to 264 bits that is highly competitive with known 32-bit implementations on 64-bit architectures (additional space required is 25% for ranking and 12.

What is an API (application programming interface)? Definition and examples A lot of people who work in technology have an intuitive understanding of what an API (application programming interface) is — but if you asked them to define it, they might have trouble putting an explanation into words. In simple terms, an API is both a piece of software running on a networked server and a component of p

グラフを扱うJavaライブラリ「Jung」の紹介 - Twitterのグラフ構造を視覚化 - public static void main
java-ja 第12回のLTで話そうと思ったのですが、出番がなかったので資料をブログで公開しておきます。 Jungは研究などでグラフ構造が出たときに、理解しやすくするために可視化するのに使っています。他にもいくつかグラフを扱うライブラリは存在していますが、日本語の資料があったのと拡張可能なことが多かったのでJungを結果的に使うようになりました。 以下はそのJungについての簡単な解説です。 Jungとは Jungの正式名称はJava Universal Network/Graph Frameworkで、ネットワーク(グラフ) 構造の分析や視覚化を行うためのJavaのOSSライブラリです。グラフ理論、データマイニング、ソーシャルネットワーク分析のアルゴリズムを数多く実装しています。 安定バージョンは1.7.6で最新は2.0betaで、BSDライセンスで使用できます。 http://jun

JAMA: Java Matrix Package
Background JAMA is a basic linear algebra package for Java. It provides user-level classes for constructing and manipulating real, dense matrices. It is meant to provide sufficient functionality for routine problems, packaged in a way that is natural and understandable to non-experts. It is intended to serve as the standard matrix class for Java, and will be proposed as such to the Java Grande For
JScience
The hardest thing in the world to understand is the income tax (Albert Einstein) To provide the most comprehensive JavaTM library for the scientific community. To create synergy between all sciences (e.g. math, physics, sociology, biology, astronomy, economics, etc.) by integrating them into a single architecture. To provide the best on-line services (webstart) for scientific calculations and visu
