Java Distribution Functions |
|
3543 clicks since Oct 19, 2003
|
|
A translation of the R distribution functions from C to Java. The translation isn't entirely pretty (especially since some of the C code was originally translated from Fortran), but it seems to work. Classes implement the PDF, CDF, and (usually) quantile and random variate generation for the following distributions: beta, hypergeometric, normal, binomial, logistic, poisson,
cauchy, lognormal, signrank,
chisquare, negative_binomial, t,
exponential, noncentral_beta, tukey,
f, noncentral_chisquare, uniform,
gamma, noncentral_f, weibull,
geometric, noncentral_t, wilcox |

Matran: A Matrix Wrapper for Fortran 95 |
|
3037 clicks since Jun 18, 2003
|
|
Matran (pronounced MAY-tran) is a Fortran 95 wrapper that implements matrix operations and computes matrix decompositions using Lapack and the Blas. Although Matran is not based on a formally defined matrix language, it provides the flavor and convenience of coding in matrix oriented systems like Matlab, Octave, etc. By using routines from Lapack and the Blas, Matran allows the user to obtain the computational benefits of these packages with minimal fuss and bother. |

A Brief Introduction to Graphical Models and Bayesian Networks |

The tutorial begins with this quote:
<p>
"Graphical models are a marriage between probability theory and graph theory. They provide a natural tool for dealing with two problems that occur throughout applied mathematics and engineering -- uncertainty and complexity -- and in particular they are playing an increasingly important role in the design and analysis of machine learning algorithms. Fundamental to the idea of a graphical model is the notion of modularity -- a complex system is built by combining simpler parts. Probability theory provides the glue whereby the parts are combined, ensuring that the system as a whole is consistent, and providing ways to interface models to data. The graph theoretic side of graphical models provides both an intuitively appealing interface by which humans can model highly-interacting sets of variables as well as a data structure that lends itself naturally to the design of efficient general-purpose algorithms.
</p>
<p>
Many of the classical multivariate probabalistic systems studied in fields such as statistics, systems engineering, information theory, pattern recognition and statistical mechanics are special cases of the general graphical model formalism -- examples include mixture models, factor analysis, hidden Markov models, Kalman filters and Ising models. The graphical model framework provides a way to view all of these systems as instances of a common underlying formalism. This view has many advantages -- in particular, specialized techniques that have been developed in one field can be transferred between research communities and exploited more widely. Moreover, the graphical model formalism provides a natural framework for the design of new systems." --- Michael Jordan, 1998.

Creating and using a timing class |
|
2435 clicks since Feb 8, 2004
|
|
The purpose of this tutorial is to talk about two seperate concepts; profiling and object oriented programming (OOP). In this tutorial we'll create a simple class to allow you to create one or more timers. You can then use these timers to show you how long a script or function takes to run, which can help you determine what portions of your script are eating up the most processing time. This is sometimes referred to as profiling. You can also use timer objects to provide generic timer display in your scripts.

Getting Started with the Eclipse Workbench - The Eclipse Workbench, at the most fundamental level, is merely a platform for software development tools and provides little functionality on its own. With the appropriate plug-in components, however, it\'s capable of supporting any type of software development. It is most commonly used for developing using the Java programming language, in large part because the SDK version of Eclipse, (which you can download from the Eclipse site), includes the Java Development Toolkit (JDT) which, together with the basic Eclipse platform, provide a full-featured Java IDE. |

Lightweight Java Game Library - The Lightweight Java Game Library (LWJGL) is a solution aimed directly at professional and amateur Java programmers alike to enable commercial quality games to be written in Java. LWJGL provides developers access to high performance crossplatform libraries such as OpenGL (Open Graphics Library) and OpenAL (Open Audio Library) allowing for state of the art 3D games and 3D sound. Additionally LWJGL provides access to controllers such as Gamepads, Steering wheel and Joysticks. All in a simple and straight forward API. |

The Java Game Development Tutorial - After a lot of hard work, we have made it to finish the English version of the tutorial. As I said, you should be already able to program in Java, although you don't have to be a expert! The tutorial will give you a very detailed introduction into the development of online games using Java. |

The K-Zone: Mastering the Java CLASSPATH - This article describes in detail how the Java compiler and the JVM use the class search path to locate classes when they are referenced by other Java code. It does this with reference to a very simple example, which uses two classes in the same package. We will see how various operations to compile these two classes succeed and fail, depending on the class path setting.

This article will describe the evolution of my engine from a sample program to a full library of portable software rendering functions, and document this library, called pGL (portable GL). The library interface is based on OpenGL (as much as a set of TI-85 programs can be based on C), because it is very simple and easy to use. |

You’ve outgrown shared hosting and decided to start renting a server of your own. Since you’re still on a tight budget, you want an unmanaged server, where full responsibility for configuring and managing the server is yours. These are the steps I go through every time I set up a new server for web and database hosting. |

Online Mathematics: Scalable Vector Graphics |
|
May 6, 2007 10:50 am
|
|
Scalable Vector Graphics (SVG) is the open source Worldwide Web Consortium (W3C) recommendation for two dimensional vector graphics. The combination of SVG and JavaScript is a powerful platform for creating interactive graphics, comparable to Flash and Java. SVG has been overlooked, however, partly because of incomplete browser support. This situation improved significantly in 2006 with the release in of Firefox 1.5 and Opera 9, both with native SVG capability. The first part of this article reviews the current status of SVG implementation and offers several examples with a mathematical flavor. The second part, for developers, explains one of the examples in detail. |
