Seminar on "Compressive Sampling" (ACTR 116, from Oct 31, 2008 09:00 AM to Oct 31, 2008 10:30 AM)

Dr. Pratt will give a seminar on "Compressive Sampling" on Oct 31st. A brief introduction to the topic is below: "Compressive Sampling or as it is alternately known as Compressive Sensing is a new approach to reducing data storage upon initial sampling. This new approach entails implementing methods of sampling a data source such that minimization of the requisite information can occur at time of acquisition. This is critical in today's world as we are acquiring data at extremely high rates and storage needs becomes more prevalent."

Seminar on "GE Heathcare's work on cardiology disease." (Tentative) (ACTR 116, from Oct 24, 2008 09:00 AM to Oct 24, 2008 10:30 AM)

Suresh Choubey from GE Healthcare will give a talk on the work they are doing on cardiology disease for the LINC group.

Seminar on "Fund Raising for IT Startups" (ACTR 117, from Oct 10, 2008 09:00 AM to Oct 10, 2008 10:30 AM)

We will have a seminar at 9:00am Friday, in ACTR 117. The speaker is Mr. Mohan Ramanujam from New York who is an IT entrepreneur. The topic (tentatively) is on fund raising for IT startups.

Seminar on "Data-Driven Prognosis of Alzheimer's Disease" (ACTR 116, from Sep 26, 2008 09:00 AM to Sep 26, 2008 10:30 AM)

Prospectus Title: Mining Potentially Useful Positive and Negative Association Patterns: Beyond Support Measures

Group Seminar: Introduction to two named entity extraction technics for biomedical literatures (ACTR 116, from May 02, 2008 09:00 AM to May 02, 2008 09:55 AM)

Biomedical information is growing explosively, new and useful results are appearing daily in research publications. To enable data mining and knowledge discovery from such documents, this data must be made available in a structured format. However, it is difficult to have human curators extract all of the information. Therefore, named entity recognition (the task of identifying words and phrases in free text that belong to certain classes of interest) is an important first step for many of these larger information management goals. In this study, three methods that are wildly used will be introduced along with some research papers.

Group Seminar: Header T-tree, A Main Memory Database Index (ACTR 116, from Apr 25, 2008 09:00 AM to Apr 25, 2008 10:30 AM)

by Sandeep Uda Abstract: Memory resident database systems (MMDB's) store their data in main physical memory and provide very high-speed access. There are many index structures proposed which are suitable for MMDBs. T-tree has been widely accepted as a promising index structure for main memory databases. It is a balanced tree that evolved from AVL and B-trees, and a binary tree with many elements in a node. All the basic operations like insertion, deletion, update, searching single-value query and searching range queries are discussed along with their advantages and disadvantages and a new index structure is proposed which is a variation of T-tree, will be discussed with examples.

Group Seminar - "Spatial Database and Indexing" by Murat Seckin Ayhan (ACTR 116, from Apr 18, 2008 09:00 AM to Apr 18, 2008 10:30 AM)

Abstract: Systems concerning of spatial data types have been frequently deployed, especially in Geographical Information Systems and applications. Various spatial access methods have been proposed for efficient query processing upon these complex and huge spatial data sets. In this study, some of these spatial access methods, R-tree, STR-tree, MX-CIF Quadtree and Gist R-tree, have been discussed and their fundamental window query performances on different data models have been focused. The performance results have showed that STR-tree has best query responses both in retrieval times and candidate sets whereas MX-CIF Quadtree stays behind R-tree as the data sets grow in size. Additionally, admirable performance gains, up-to 7-8 times, has been presented by built-in spatial index structure of PostgreSQL DBMS which is Gist R-tree.

Group Seminar - "Modeling Data using RDF" by Dr. Raghavan (ACTR 116, from Apr 11, 2008 09:00 AM to Apr 11, 2008 10:30 AM)

The presentation is on RDF- specifically comparing RDF modeling to how the same content is modeled in relational DB approach.
