a. Support Vector Machine(SVM): Over the past several years, there has been a significant amount of research on support vector machines and today support vector machine applications are becoming more common in text classification. In essence, support vector machines define hyperplanes, which try to separate the values of a given target field. The hyperplanes are defined using kernel functions. The most popular kernel types are supported: linear, polynomial, radial basis and sigmoid. Support Vector
relationships. We used our technique to three benchmark data sets from the UCI machine learning repository for soil categorization and they were namely Statlog (Landsat Satellite), Covertype, and 3 data sets. Our objective was to develop an efficient classification model with the proposed method and, therefore compare its performance with two well-known supervised classification algorithms Multilayer Perceptron and Support Vector Machine. We estimated the performance of these classification techniques in terms
section{Introduction} Many new forms of communication have emerged in the past few decades such as text messaging and have become quite popular and important. These new forms of communication convey huge range of information and are also popularly used to share sentiments and opinions about different events and topics. We have worked on the following task. The task is: egin{itemize} item Given a message, classify whether the message is of positive, negative, or neutral sentiment. For messages
knowledge or skills from data is too hard and complicated for machines. Moreover, the intelligence level of a machine is directly relevant to its learning capability. The study of machine learning tries to deal with this complicated task. In other words, machine learning is the branch of artificial intelligence that tries to find an answer to this question: how to make computer learn? When we say that the machine learns, we mean that the machine is able to make predictions from examples of desired behavior
retrieving opinions, performing processing on the data and analyzing the data using machine learning techniques to classify them by sentiment as positive, negative or neutral. I proposed sentimental natural language processing method for processing the text and use various machine learning algorithms and feature selection methods to determine the best approach. The approaches towards sentiment analysis are machine learning based methods, lexicon based methods and linguistic analysis. I proposed sentimental
Introduction: I have decided to compare Raster (bitmap) and Vector graphics & their uses in modern digital multimedia. I will begin by defining what both mean. Then take a brief look into how they were first utilised. Give examples of their pros and cons, their uses now & express my opinion as to which one I believe to be better option and why. Raster (bitmap) graphics definition: “A raster graphic is a digital image composed of a matrix of dots. When viewed at 100%, each dot corresponds
technology and automatic speech recognition is a driving force in this process. Speech recognition technology is changing the way information is accessed, tasks are accomplished and business is done. Automatic speech recognition (ASR) is the ability of a machine to convert spoken language to recognized words. 2.1 TYPES OF ASR SYSTEMS ASR can be classified in sever... ... middle of paper ... ...CHART REFERENCES [1] S.

Cancer has become leading cause of death across world in the class of non-communicable diseases. This has led to massive research in cancer diagnosis and prognosis. Diagnosis of cancer in early stages could prevent its spread to other organs of the body and possible cure of the patient. More and more different types of cancers are being identified and mostly they have to be treated differently. Cancer classification plays a very important role in cancer diagnosis. Earlier strategies used for cancer
three benchmark data sets from the UCI machine learning repository for detection of breast cancer; they were namely Wisconsin Breast Cancer (WBC), Wisconsin Diagnostic Breast Cancer (WDBC), and Mammographic Mass (MM) data sets. Our objective was to diagnose and analyze breast cancer disease with the proposed method and, therefore compare its performance with two well-known supervised classification algorithms Multilayer Perceptron and Support Vector Machine. We evaluated the performance of these
Interior Gateway Routing Protocol Enhanced Interior Gateway Routing Protocol is a distance vector routing protocol, where a router shares information with neighboring routers about the network in an autonomous system and shares only the information that neighboring routers don’t have instead of the whole message. It is an enhanced version of Interior Gateway Routing Protocol, both of them uses the same distant vector technology and the distance information within them is not changed. EIGRP is also called
relishing field of study that that deal with people’s opinions, sentiment , emotions and attitudes about different entities such as products ,service ,individuals ,companies ,events and topics; and includes many fields like natural language process, machine learning, computational linguistic ,statistics, and artificial intelligence . it’s a set of computational and natural language techniques which could be leveraged in order to extract subject information in a given text . The research of sentiment
Abstract- In this paper the method face Recognition is using to access Automated teller machines (ATMs). ATMs are used to do banking function like checking balance withdraw money, changing pin numbers etc. The ATM cards and pin numbers are used for security purpose. But this system is using SIM card in place of ATM cards. In order to improve security the system first authenticate the person if he/she is recognized then it will ask the password of the account. This system used Spartan 3 FPGA board
significant new ways of attacks. In November 2012, researchers from the University of North Carolina, the University of Wisconsin and RSA Corporation released a paper describing how a virtual machine could use side channel timing information to extract private cryptographic keys being used in other virtual machines on the same physical server [2]. However, according to CSA [1] in many cases an attacker wouldn’t even need to go to such lengths. If a multitenant cloud service database is not properly designed
Process) Data Mining (DM), or Knowledge Discovery is extraction of implicit, hidden trends, previously unknown, and useful information from data. DM research adopted many techniques from research areas like artificial intelligence, statistics and machine learning. Stages in Data Mining: 1. Selection of data: selecting data to be analysed. 2. Preprocessing: Preprocessing of data to ensure consistent and common format. This is the data cleaning stage where certain information is removed and dicarded

Machine learning can considered as an ideal approach to deal with many problems that currently exist in various areas such as multimedia processing, pattern recognition and computer security. Machine learning techniques also can use in digital forensics to solve complex problems in extracting and analysis digital evidence from crime scene. There are several areas in digital forensics where machine learning techniques can be used as

I consider myself fortunate to be part of the Department of Computer Science, University of Florida for my master studies. More importantly, I am glad to have two excellent professors in this field as advisors, Dr. Pader and Dr. Jilson, who are guiding me throughout my graduate studies. They assisted me to decide and pursue the courses
Abstract—Sign Language is the language used by deaf and dumb people for communication in their day to day life. Every nation has its own sign language. Indian people use Indian Sign Language. Generally other sign language such as ASL (American Sign Language) and BSL(British Sign Language) is single handed sign language while ISL is the language which uses both hands to make signs. So it is difficult to exactly classify and recognizes those types of signs. The work presented here focuses on recognizing
In recent years, the demand to develop hybrid vehicles is increasing due to concern over environment depletion and energy insecurity. Auto-manufacturers are striving to develop many alternatives to curb fuel consumption and greenhouse emissions, one such alternative known as “Integrated Starter Generator (ISG)” most commonly used in mild hybrid vehicles. Integrated Starter Generator is an electrical device which replaces the conventional starter, alternator and flywheel in the vehicles by performing
