Data Mining

Monday, August 10, 7-9 pm

Ash has provided a copy of his slides. Also available is a video recording of the presentation.

The August program in Orange County will feature Dr Ash Pahwa, who will speak to us about the technical issues and applications of data mining and predictive modeling technologies. There is a great need for automatic review and analysis of large amounts of data constantly being generated in order to extract meaningful information. An increasing volume of research and industry data is being collected on a daily basis. Intelligent software tools are increasingly needed to process and filter the data, detect new patterns and similarities and extract meaningful information. Large databases of information create great opportunities for the application of data mining methods.

Conventional statistical analysis and computer science algorithms even though useful are not powerful enough in solving many of the knowledge discovery problems. Data mining approaches (eg neural networks, decision trees, regression trees, clustering), are ideally suited for domains characterized by the presence of large amounts of noisy data, and the absence of general theories or hypothesis about the data. Data mining and predictive modeling offer a means of effective classification and analysis of this multi-dimensional data, leading to discovery of functional models, trends and patterns. Data mining and predictive modeling are capable of automatic extraction of knowledge deeply hidden in the data, enabling discovery of knowledge about data not otherwise attainable.

Dr Pahwa, PhD, is the founder and CEO of AssaySoft, Inc, which introduced "cellAnalyst" image analysis software for the Microsoft Windows/.NET platform. The "cellAnalyst" is also available as a web service. The coding for cellAnalyst was done in C#/ASP.NET/AJAX environment. He has built numerous desktop and web applications on the Windows platform. His expertise includes image processing, database management, digital video and data storage technologies. He developed "iVision" an image database management system for storage and retrieval of biomedical images based on metadata, annotation and content. The iVision was developed under a research grant from National Institute of Health while working at University of California, Santa Barbara. The algorithms of iVision were developed and tested using MATLAB. Dr Pahwa has taught Digital Image Processing course at University of California, Irvine in winter 2007.

Dr Pahwa has over 25 years of experience in the industry. He has worked for General Electric, AT&T Bell Laboratories, Xerox Corporation, and Oracle. Before starting AssaySoft, Inc, Dr Pahwa started DV Studio, Inc, which introduced successful products for CD-Recording (CDR) and MPEG encoding. Dr Pahwa also successfully designed and marketed various MPEG-1 and MPEG-2 hardware encoders used in the DVD creation market. His book, "CD-Recordable Bible" (Pemberton Press, 1994), was translated into Japanese and German. He has taught numerous courses at UCLA Extension on CD-ROM/DVD and MPEG technologies. He is listed in "Who's Who in the Frontiers of Science and Technology". He holds a PhD in Computer Science from the Illinois Institute of Technology in Chicago.
