Java Distribution Functions |

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 |
|

|
|
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 |
|
2436 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.

AI::Categorize - This module implements several algorithms for automatically guessing
category information of documents based on the category information of
existing documents. For example, one might categorize incoming email
messages in order to place them into existing mailboxes, or one might
categorize newspaper articles by general topic (business, sports, etc.).
All of the categorizers learn their categorization rules from a body of
existing pre-categorized documents.

Dan Roth - My research focuses on the computational foundations of intelligent behavior. We develop theories and systems pertaining to intelligent behavior using a unified methodology -- at the heart of which is the idea that learning has a central role in intelligence. In doing that we pursue several interrelated lines of work that span several aspects of this problem -- from theoretical questions in learning, knowledge representation and reasoning to experimental paradigms and large scale system development -- all pertain to the idea that learning is of prime importance in performing knowledge intensive inferences and use the natural language domain as the main application area. |

The Cross-Entropy Method - This web site is a collection of information and links about the Cross-Entropy method. Pioneered in 1997 by Reuven Rubinstein as an efficient method for the estimation of rare-event probabilities, the cross-entropy (CE) method has rapidly developed into a powerful and versatile technique for both rare-event simulation and combinatorial optimisation. The method derives its name from the cross-entropy (or Kullback-Leibler) distance - a well known measure of \"information\", which has been successfully employed in diverse fields of engineering and science, and in particular in neural computation, for about half a century.

You’ve outgrown shared hosting and decided to start renting a server of your own.

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. |
