Conventional linear & nonlinear tools for classification, regression & data driven modeling are being replaced on a rapid scale by newer techniques & tools based on artificial intelligence and machine learning. While the linear techniques are not applicable for inherently nonlinear problems, newer methods serve as attractive alternatives for solving real life problems. Support Vector Machine (SVM) classifiers are a set of universal feed‐forward network based classification algorithms that have been formulated from statistical learning theory and structural risk minimization principle. SVM regression closely follows the classification methodology. In this work recent applications of SVM in Chemo & Bioinformatics will be described with suitable illustrative examples.

作者： Parikshit Godbole Anshul Batth Nandakumar Ramaswamy Hardware Technology Development Group Center for Development of Advanced Computing Pune India

Systems employing multiple FPGAs to handle distributed processing require data communication among FPGAs for unified operation. This paper describes implementation of a multi-lane Low Voltage Differential Signaling (LVDS) interface to form 10 Gbps full duplex communication link interconnecting multiple FPGAs on a board. The design utilizes advanced IO resources available in the latest Virtex and Spartan series of FPGAs from Xilinx. We also developed a Bit Error Rate Tester for evaluating each individual LVDS physical lane operating at 625 Mbps. Challenges involved in the board design, related to implementation of the interface, are also discussed in this paper.

International Workshop on Frontiers in Handwriting Recognition

作者： Swapnil Belhe Chetan Paulzagade Sanket Surve Nitesh Jawanjal Kapil Mehrotra Anil Motwani Center of Development of Advanced Computing (CDAC) GIST Group Pune India

In this paper we describe the semi-automatic annotation tool for annotating online handwritten data of Indic scripts. The annotation of handwriting data is essential to train and test the recognizers. In this paper we briefly describe the XML representation for storing online handwritten data in Indian languages. We then describe the annotation tool which essentially annotates at stroke, character and word level and exploits the uniqueness of XML standard to provide quality labels at different levels of annotation. The tool also facilitates classification of data based on quality of handwriting, age & region of writers. The annotator can verify the outputs suggested by the tool. The tool is supplemented by a utility for data segregation and accuracy calculator which aids quick performance analysis of recognizer. This tool is extensively used for annotating large amount of Hindi data and promising time saving is obtained in otherwise tedious annotation activity.

The advent of GPGPU technologies has allowed for sensible speed-ups in many high-dimension, memory-intensive computational problems. In this paper we demonstrate the effectiveness of such techniques by describing two applications of GPGPU computing to two different subfields of computer graphics, namely computer vision and mesh processing. In the first case, CUDA technology is employed to accelerate the computation of approximation of motion between two images, known also as optical flow. As for mesh processing, we exploit the massively-parallel architecture of CUDA devices to accelerate the face clustering procedure that is employed in many recent mesh segmentation algorithms. In both cases, the results obtained so far are presented and thoroughly discussed, along with the expected future development of the work. © The Eurographics Association 2010.

From recent past, the computational Grid based flood assessment and forecasting models is getting emerged as an interdisciplinary integrated `near real time/real time model'. Many such, Grid based flood assessment and forecasting model supports in logically integrating various components of flood related scientific simulations such as Metrological, Hydrological, Hydraulic, RADAR, LIDAR Remote Sensing, GIS, Satellite Communication and other technologies and derives the end result which can be straight away used by the disaster mitigation team member/end user. This paper mainly brings out the emerging technological trends observed in the fields of computational Grid based flood assessment and forecasting models by surveying the flood forecasting model of `Cross Grid' as well as the operational flood model of ESA Grid. Details reflecting the technology trends and simulation methods adopted by the `GARUDA Grid' flood assessment experimental model have been given.

Being an indicator of economic growth, the deployment of an Intelligent Transportation System (ITS) became an imperative necessity of a country, whether developed or developing. Emergence of innovative technologies in the areas of Computer Science, ICT and Digital Image Processing paved way to the implementation and the deployment of such a system in a cost effective and economic manner. Introduction of a system with minimal disturbance of the heterogeneous environment with minimum cost and time in R&D and deployment will be an important criteria in the selection of such a system for a developing country. The intelligent Transportation System can be considered to be constituted with multiple layers of integrated innovative technologies. The recent advancements in third and fourth generation wireless data communication as one of the access technologies and the deployment of high-speed secure information highway established with a national level computer backbone network in developing countries made the deployment of such a system in an efficient manner which form the physical layer of ITS. The technological layer of ITS can be formed with IP based Sophisticated intelligent Camera technologies and with the application of intelligent algorithms on advanced digital image processing techniques, which can be implemented in a multi-layer architecture and deployed in multiple stages, which will make the system robust and will be making the environment gradually standardised, without much disturbances. The standardised vehicle licence plate is the raw data of ITS, which may or may not be standardised in developing countries. The introduction of the concept of a repository of non-standardised licence plates left after the application of layered advanced digital image processing algorithms injected in ITS will enable the gradual standardisation of the environment.

Numerous class cohesion metrics can be found in the literature. However, they end up capturing different aspects of cohesion. Which metric is best suited for a given situation is always a critical question. This work focuses on exploring the strengths and weaknesses of each of the selected cohesion metrics. The issues of their applicability to capture varying strengths of cohesion and ability to identify disparate classes are addressed. The metrics are classified into five categories based on their computational approaches. Diversity and similarity among these metrics are brought out. The discussion demonstrates uses of cohesion metrics with the help of typical representative situations.

The World Wide Web is an interlinked collection of billions of documents formatted using HTML. Ironically the very size of this collection has become an obstacle for information retrieval. The user has to shift through scores of pages to come upon the information he/she desires. Web crawlers are the heart of search engines. Web crawlers continuously keep on crawling the web and find any new web pages that have been added to the web, pages that have been removed from the web. Due to growing and dynamic nature of the web;it has become a challenge to traverse all URLs in the web documents and to handle these URLs. A focused crawler is an agent that targets a particular topic and visits and gathers only relevant web pages. In this dissertation I had worked on design and working of web crawler that can be used for copyright infringement. We will take one seed URL as input and search with a keyword, the searching result is based on keyword and it will fetch the web pages where it will find that keyword. This focused based crawler approach retrieve documents that contain particular keyword from the user's query;we are implementing this using breadth-first search. Now, when we retrieved the web pages we will apply pattern recognition over text. We will give one file as input and apply the pattern recognition algorithms. Here, pattern symbolizes text only and check how much text is available on the web page. The algorithms that I had used for pattern search are Knutt-Morri-Pratt, Boyer-Moore, Finite Automata algorithm.

The continuous search for endurance has transformed the world into a place filled with electronic and digital security systems. Emerging technologies have metamorphosed the nature of surveillance and monitoring applications, but the sensory data collected using these gadgets still remains unreliable and poorly synchronized. In this paper, we detail a research project named Intelligent Intrusion Detection System (In2DS) for remote surveillance and monitoring applications which can greatly improve the existing systems in terms of energy, cost and performance. The motivation for developing In2DS stems from the fact that Wireless Sensor Networks (WSN) can provide wider sensing coverage, night & harsh weather surveillance, multi-sensor data fusion and in-network data processing thereby enhancing existing intrusion detection capabilities and improving alarm functionalities. We present preliminary results based on the field experiments conducted as part of the project and provide an in-depth analysis of Passive InfraRed (PIR) sensor detection performance.
