Topic Modeling. Topic Modeling Topic models provide a simple way to analyze large volumes of unlabeled text.
A "topic" consists of a cluster of words that frequently occur together. Using contextual clues, topic models can connect words with similar meanings and distinguish between uses of words with multiple meanings. For a general introduction to topic modeling, see for example Probabilistic Topic Models by Steyvers and Griffiths (2007). For an example showing how to use the Java API to import data, train models, and infer topics for new documents, see the topic model developer's guide. The MALLET topic model package includes an extremely fast and highly scalable implementation of Gibbs sampling, efficient methods for document-topic hyperparameter optimization, and tools for inferring topics for new documents given trained models.

Storm, distributed and fault-tolerant realtime computation. Doubly linked list. A doubly-linked list whose nodes contain three fields: an integer value, the link to the next node, and the link to the previous node.
The two node links allow traversal of the list in either direction. While adding or removing a node in a doubly-linked list requires changing more links than the same operations on a singly linked list, the operations are simpler and potentially more efficient (for nodes other than first nodes) because there is no need to keep track of the previous node during traversal or no need to traverse the list to find the previous node, so that its link can be modified. Nomenclature and implementation[edit] Basic algorithms[edit] Open doubly-linked lists[edit] record DoublyLinkedNode { prev // A reference to the previous node next // A reference to the next node data // Data or a reference to data } record DoublyLinkedList { DoublyLinkedNode firstNode // points to first node of list DoublyLinkedNode lastNode // points to last node of list } Traversing the list[edit]
Joseph Weizenbaum. Joseph Weizenbaum (8 January 1923 – 5 March 2008) was a German and American computer scientist and a professor emeritus at MIT.
The Weizenbaum Award is named after him. Life and career[edit] Born in Berlin, Germany to Jewish parents, he escaped Nazi Germany in January 1936, emigrating with his family to the United States. He started studying mathematics in 1941 at Wayne University, in Detroit, Michigan. Delab.csd.auth.gr/papers/AIAISYMEON.pdf. Substance · Towards open digital publishing. Uhuru Software.

Art meets the open web. Announcing the Mozilla Eyebeam Open(Art) Fellows Stefan Hechenberger and Addie Wagenknecht, Toby Schachman and Forrest Oliphant Today, Mozilla and the Eyebeam Art + Technology Center are pleased to announce the recipients of the first-ever Open(Art) Fellowships.
Together, these creative technologists will be exploring the frontier of art and the open web as part of our new Open(Art) program. Pushing the boundaries of creative code Supported in part by an award from the National Endowment for the Arts, the Open(Art) initiative is all about supporting projects that facilitate artistic expression and learning on the open web, using code to enable cutting-edge art, media and hardware production. Over the next six months, the fellows will create open source tools and works that enable creative production and open participation. Lucene - Apache Lucene Core.

The HTML5 Media Framework. Customer development 2012. API. The future is now: 10 startups leading the way in ‘big data’ How can big data and smart analytics tools ignite growth for your company?
Topological analysis. API. An Entrepreneur's Guide to Relationship Management: Who To Keep in Touch With, and How Often. Editor’s Note: This blog post has been excerpted from an article that was originally published by Zvi Band on the Contactually blog.
When running my previous company, staying in touch was crucial to my business. We were one of dozens, maybe hundreds, of web development firms in the DC region, but we kept really busy (sometimes overwhelmingly so) thanks to a continual flow of referrals from past clients and our network. Come to think of it, I never accepted a client that came via anonymous websites (read: my own website).
So relationship management was a core aspect of my role as founder. What If Your Smartphone Could Read Your Mind? Kimera Is Working On It.
BOOM Goes The Dynamite! 500 Startups Explodes With 2 New Periodic Elements, 12 Sensational Startups, and 1 Awesome Accelerator Program. 500 Startups announces today they have discovered the newest periodic elements – Upandtotherightium (Ur) and Viralium (Vi).
In addition to this amazing new discovery which is awaiting official recognition by the International Union of Pure and Applied Chemistry, they are also proud to announce they are in the early stages of developing 12 remarkable new startups in their just-launched 500 Startups Accelerator program at their headquarters in Mountain View. The buzz among the science community is the 500 Startups Accelerator will soon eclipse the CERN Large Hadron Collider in Geneva, Switzerland, which has long held the title of the world’s largest and highest-energy particle accelerator. Several Russian physicists have raised concerns this new 500 Startups Accelerator could be dangerous and has the potential for creating wormholes with unknown outcomes, possibly even the creation of a black hole. Specs of the 500 Startups Accelerator are detailed below To learn more, visit.
