Database Mining Tutorial What's Database Text Mining? This tutorial shows how to use a relational database management system (RDBMS) to store documents and LingPipe analyses. It uses MEDLINE data as the example data, and MySQL as the example RDBMS. For expository purposes, we break this task into three parts: Loading MEDLINE data into the database, using the LingMed MEDLINE parser and the JDBC API to access a RDBMS.Using the LingPipe API to annotate text data in the database, and to store the annotations back into the database.SQL database queries over the annotated data. Completing part 1 results in a simple database containing a table containing the titles and abstracts of MEDLINE citations. MySQL MySQL runs on most operating systems, including Linux, Unix, Windows, and MacOS, and is available under both a commercial and GPL license. MySQL 5.0 Download Page. You will only need the "essentials" version for Windows x86 or AMD64. The official JDBC driver for MySQL is available from the Creating the database
The Cyc Foundation (Navigation privée) We’re pleased to bring you an update on several recent activities related to OpenCyc and the Semantic Web. UMBELThe lightweight UMBEL ontology is finally live. Mike Bergman and Fred Giasson deserve a big round of applause for the tremendous effort they’ve put into this release. They’ve meticulously selected 20,000 of the most relevant concepts from the more than 300,000 in the Cyc KB. What’s more, relationships between these concepts have been simplified to facilitate discovery of related concepts and alignment with external ontologies. One can use UMBEL to describe things, to help develop new ontologies and to put individuals in context. Wikipedia and OpenCyc AlignmentWe collaborated with Olena Medelyan and Catherine Legg of the University of Waikato, New Zealand in their effort to automatically identify ontologically equivalent concepts in Cyc and Wikipedia. Details and downloadable versions of the mappings can be found at the project website.
One way to control shader parameters The basic idea is making a shader with which you can control the surface's reflection characteristics by editing its BRDF in the GUI. Simple BRDF has two parameters. By mapping the two parameters to the angle components theta, phi of a polar coordinate, and mapping the reflectance ratio (so not BRDF, strictly speaking. I just used the term BRDF for explanation) to the r components of the polar coordinate, you can make a 3D shape that represents a BRDF (not BRDF strictly ...) I made a test shader looooong time ago. The usage is limited of course.

RDF For The Rest Of Us (Navigation privée The web professional's online magazine of choice. In: Articles By Keith Alexander Published on July 30, 2007 You have a website full of information, and you want to make it easier for people to reuse it—but what format should you publish it in? You’ve looked at various XML schemas and microformats, but none of them really describes all the information that you want to publish. This is where RDF comes in. What is RDF? stands for Resource Description Framework. resource is simply a thing; a person, a book, a keyboard, a blog post, a fish tank, an idea: any thing that can be described. RDF for Web Publishers RDF is different. If you find a vocabulary that can be used to describe some part of your data, then great, that data can be interoperable; you still have the freedom to describe the rest of your data with terms from as many other vocabularies as you need. For publishing your data, RDF offers you great flexibility and interoperability. Fantastic. RDF for Web Developers What is an RDF Triple?
Curedale LIBSVM -- A Library for Support Vector Machines LIBSVM -- A Library for Support Vector Machines Chih-Chung Chang and Chih-Jen Lin Version 3.20 released on November 15, 2014. LIBSVM tools provides many extensions of LIBSVM. We now have a nice page LIBSVM data sets providing problems in LIBSVM format. A practical guide to SVM classification is available now! To see the importance of parameter selection, please see our guide for beginners. Using libsvm, our group is the winner of IJCNN 2001 Challenge (two of the three competitions), EUNITE world wide competition on electricity load prediction, NIPS 2003 feature selection challenge (third place), WCCI 2008 Causation and Prediction challenge (one of the two winners), and Active Learning Challenge 2010 (2nd place). Introduction LIBSVM is an integrated software for support vector classification, (C-SVC, nu-SVC), regression (epsilon-SVR, nu-SVR) and distribution estimation (one-class SVM). Since version 2.8, it implements an SMO-type algorithm proposed in this paper: R. Download LIBSVM
EnterTheSingularity Iñigo Quilez - home page Intro Current graphics cards are very powerfull, but only because they do "simple" things. In other words, GPUs only have fast implementations for those things that are expected to make a game look great. No complain about that of course. But when something else is needed, and that something else is a little bit out of the usual requirements for a game, things do not go that well anymore. For example, texture filtering is one of those things that look great in games, but in reality the quality of current implementations is quite poor for other purposes. The Thing Linear interpolation is of course much better than the simpler nearest-rounding way of sampling a texture. Usually one should use bicubic interpolation (or even higher order interpolators) to get smooth results. vec4 getTexel( vec2 p ) { return texture2D( myTex, p ); } and therefore which gets value 0 both for x=0 and x=1, which are the extrema of the usual interpolation range (0..1).
Marko Prljić Portfolio Ca3D-Engine Home Flare | Apps | Dependency Graph This visualization shows the dependencies among classes within the Flare library. Classes are paced along a circle with the radius length signifying the depth of the class in the package structure. A link indicates that a class imports another. Links are routed along the package structure tree, forming “bundles” between packages. When the mouse hovers over a class, the incident links will highlight. Clicking on a class shows the chain of dependencies for that class. Clicking a second time similarly shows all classes that in some form depend on the selected class. As the labels can be small and hard to read in a constrained web page, take a look at the full size version for a more legible graph. Launch full size version. View the source code.
