The Heart Disease Prediction System Computer Science Essay

The Heart Disease Prediction System Computer Science Essay There are enormous amount of data available from medical industry which could be useful for medical practitioners when it is used for discovering hidden pattern with help of existing data mining techniques. The basic medical records from a patients profile can be useful in identifying hidden pattern with data mining techniques. In this paper, NaÃÆ'Â ¯ve Bayes algorithm to predict heart disease is implemented with basic records of patients like age, sex, heart rate, blood pressure etc., from a sample dataset. The benefits, limitations, and technical details of this implementation will also be discussed in this paper. 1 Introduction Over these years in medical history, many types of medical problems have been identified and many data are available regarding a particular problem. But not all the medical data are same, but there are many patterns hidden inside those data which needs to be identified. Data mining techniques could help identify these hidden patterns by knowledge discovery. In the medical field, patients health issues are predicted by doctors intuition or experience [2] where the knowledge rich data is suppressed which results in high medical expenses and unnecessary medical tests. In recent years, there are many researches being conducted in order to find the hidden pattern from basic medical data [1]. Identifying these hidden pattern would result in a developing an efficient decision making system in medical industry which aide as a tool to support doctors decision making or at least serve as a prediction system for any medical issues. In this paper, we have taken into consideration of heart disease and predict it using the set of data that are already in existence with the help of data mining technique. The algorithm that we have chosen is the NaÃÆ'Â ¯ve Bayes algorithm, this algorithm is ideal for a vast amount of database that may contain hundreds and thousands of rows and columns. The NaÃÆ'Â ¯ve Bayes algorithm provides the intended output faster and more accurate as the number of data in the database increase. 1.1 Problem Scenario There are only few decision support systems available in medical industry whose functionalities are very limited. As mentioned earlier, medical decisions are made with doctors intuition and not from the rich data from the medical database. Wrong treatment due to misdiagnosis causes serious threat in medical field. In order to solve these issues data mining solution was with help of medical databases was introduced. 1.2 Related Work There are many techniques available to discover knowledge from medical database [1]. Researchers at Southern California used data mining technique to discover the success and failure of back surgery in order to improve medical treatment [3]. Shouman et al [4] implemented predictive data mining to diagnose heart disease of patients. Palaniappan et al [2] developed a prototype Intelligent Heart Disease Prediction System (IHDPS), using data mining techniques. 1.3 Objective In this paper, NaÃÆ'Â ¯ve Bayes algorithm to predict heart disease is implemented with basic records of patients like age, sex, heart rate, blood pressure etc., from a sample dataset. Based on the literature survey NaÃÆ'Â ¯ve Bayes algorithm was found to be an effective technique. The probabilistic method helped in finding the converse probability of the conditional relationship. The dependence relation may exist between two attributes of data set which can be determined with this algorithm. 2 Data Preparation In order to implement the algorithm, a medical data was required. The sample dataset used for the purpose of implementation of algorithm was obtained from Cleveland Clinic Foundation. The sample of dataset is shown in the below figure (Figure1.) C:UsersMadan KumarDesktopUntitled2.jpg Figure1. Sample dataset 2.1 Dataset Source The Cleveland institute medical data was downloaded from website of University of California, Irvine. 2.2 Dataset Attributes The dataset consists of 16 attributes. The last attribute of dataset consists of value 0 and 1. The value 0 indicates that the patient does not have heart disease whereas 1 indicates that the patient has a heart disease. The prediction of algorithm can be verified with this value while evaluating the algorithm. The first 15 attributes are shown in the figure2. C:UsersMadan KumarDesktopattri.jpg Figure2. Dataset attributes 3 Program Architecture The program was implemented using JAVA. Apache TOMCAT server and MySQL Database is also used. The NaÃÆ'Â ¯ve Bayes algorithm has three class files: Calculation.java, Prediction.java, and Detection.java. Detection.java reads the data file from the source path and stores the attributes into temporary array list. The mean and standard deviation values calculations are performed and probability calculation is also done in Prediction.java. All the dataset attributes are defined in calculation.java where mean and standard deviation of attributes were calculated. The calculation.java calls the other two classes while executing the program. Figure3 represents the program architecture. C:UsersKirubanidhyDesktopArchitecture.jpg Figure3. Architecture 3.1 Building and running a Demo TOMCAT server is used to present the output in web based form. The output will run in localhost. The MySQL database is used to identify the patient records. At the execution point, the local host is accessed and 15 questions will be displayed which will be obtained from user and algorithm will be called to calculate and predict the disease possibility on that person. A report will be generated at the end of the demo which says if the person is predicted with heart disease or not. In general, 1. Obtains the values from user. 2. Reads the data file. 3. Calls the algorithm and calculates mean, deviation, and probability of attributes. 4. Generates a report displaying the values given with the prediction of disease. 4. Implementation All the attributes of dataset is of a numerical value that has some meaning. The meaning of dataset attributes are as shown in figure2. Example: the attributes sex is denoted with values 1 and 0 where 1 denotes Male and 0 denote Female. Fasting blood sugar values are also denoted using 1 and 0 where 1 denotes >120mg of fasting blood sugar level and 0 denotes These values from the data file are accessed by the NaÃÆ'Â ¯ve Bayes algorithm. The values 0 and 1 are extracted from data file and stored to an array list for each attribute e.g. age array list, sex array list, and chest pain type array list etc., in order to perform calculation. Here, the values are defined on what those values stands for before storing to the array list. The sample of the interface (for obtaining slope value) is shown in figure4. Here the un-sloping, flat, and down- sloping represents the value 1, 2, and 3 respectively. C:UsersMadan KumarDownloadsUntitled.jpg Figure 4. Interface Sample C:UsersMadan KumarDownloadsUntitled2.jpg Figure5. Sample of report format 5. Modules Description Analyzing the Data set The attribute Diagnosis was identified as the predictable attribute with value 1 for patients with heart disease and value 0 for patients with no heart disease. The attribute PatientID was used as the key; the rest are input attributes. It is assumed that problems such as missing data, inconsistent data, and duplicate data have all been resolved. Naives Bayes Implementation in Mining Bayes Theorem finds the probability of an event occurring given the probability of another event that has already occurred. If B represents the dependent event and A represents the prior event, Bayes theorem can be stated as follows. 5.2.1 Bayes Theorem Prob (B given A) = Prob (A and B)/Prob (A) To calculate the probability of B given A, the algorithm counts the number of cases where A and B occur together and divide it by the cases where A occurs alone. Applying NaÃÆ'Â ¯ve Bayes to data with numerical attributes, predict the class using NaÃÆ'Â ¯ve Bayes classification: Figure6 (a) Top Mean (b) Bottom Standard Deviation Figure6 (c) Laplace Transform 6. Evaluation User enters the values for the questionnaire to find out whether the patient has a heart disease or not. By feeding sample data from the dataset and performing the mining operations with the NaÃÆ'Â ¯ve Bayes algorithm, it is found out that the NaÃÆ'Â ¯ve Bayes algorithm gives 95% probability in predicting if patient have heart disease or not. 95% accuracy is quite good to use as a decision support system. The figure shows the accuracy of NaÃÆ'Â ¯ve Bayes algorithm (figure7). The figure shows the highest probability of correct predictions and lowest probability of incorrect predictions. C:UsersMadan KumarDesktopUntitled1.jpg Figure7. Model Results of three algorithms [2] 7. Limitations Apart from the benefits like probabilistic approaches and fast reliable algorithm of NaÃÆ'Â ¯ve Bayes, the serious shortcoming of the algorithm is its ability in handling small datasets. NaÃÆ'Â ¯ve Bayes classifier requires relatively large dataset to obtain best results. Yet, studies showed that Naive Bayes algorithm outperforms other algorithms in accuracy and efficiency. Notable limitation of this paper is the usage of small dataset. This dataset can be used for training or testing purpose only. Also the dataset could include more attributes for a more effective prediction in supporting clinical decisions. 8. Future Work The algorithm is working well with this sample dataset. Implementing the algorithm with large dataset could give better results which can aid as a supporting tool in making medical decisions. In future, other possible algorithms could be implemented where efficiency of all algorithms could be analyzed to decide on best suitable technique in terms of speed, reliability, and accuracy. 9. Conclusion In this paper, NaÃÆ'Â ¯ve Bayes algorithm is the only algorithm used for calculation of attributes and prediction. Efficiency and accuracy of the algorithm in predicting were discussed. Designing effective models are constrained by size of the datasets and noisy, incorrect, missing data values. The prototype developed so far has been generally tested by computer experts and not by the doctors. For effective understanding of the health issues, medical experts have to work collaboratively and test the prototypes in order to implement the system in real life to support medical experts in taking clinical decisions.

Essay on the Soul of the Artist in A Portrait of the Artist as a Young

Soul of the Artist in A Portrait of the Artist as a Young Man      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   As James Joyce's A Portrait of the Artist as a Young Man unfolds, protagonist Stephen Dedalus' personal vision grows closer and closer to that of an "artist." Stephen attempts throughout the story to understand the inspiration he receives while being tormented by influences that seem to distract him. Stephen's thoughtful approach to his experiences, brings him through his tormented youth to a refined understanding of his feelings about art. After explicitly stating his aesthetic theories, Stephen composes a villanelle whose structure and classically Joycean crafted diction implicitly represent Stephen's entire story. Once the parallel is established, it becomes clear that the poem -- and especially its recurring lines -- represent the epiphany for Stephen in terms of his self-discovery. In composing the villanelle, Stephen -- at this point a raw, untested visionary -- throws off the distractions of religion and sexuality to begin to grow specifically into his perceived role as creator of his race's conscience. *** The structure of Stephen's villanelle as a whole -- from its stanza construction to its length -- is the first step toward a sense of to A Portrait's overall purpose. Let us first consider why Joyce chose the villanelle as Stephen's method of communication. The aba rhyme scheme of this type of poem, with not only ending vowel sounds but entire lines recurring, forces the composer into a very confined, ordered narrative space. Stephen's definition of art includes a "cadence" and a sense of fluidity (483). From this it is reasonable to conclude that this piece, with a definite rhythm and a flowing style, is the protagonist'... ...adder" from stanza to stanza in the villanelle is, therefore, a representation of his growth throughout the novel: moments of brilliant insight peppered throughout a slow (and still continuing) growth process -- as at the end of the villanelle, Stephen reverts into the first-person lyrical style in his diary in the final section. Stephen's villanelle, as evidenced especially by its repeated rejection of ardor and enchantment, allows the protagonist to remove from his imagination two nagging distractions as he begins to work toward the religionless, asexual soul of an artist "refined out of existence, indifferent, paring his fingernails" (483).

Marketing $100 Laptop

Mr. Negroponte wanted to create educational opportunities for the world’s poorest children by providing each child with a low cost laptop. This laptop will have educational software to provide children with otherwise unavailable technological learning opportunities. OLPC provides an interesting vantage point from which to examine the dynamics between non-profit and for-profit competitors because of the rapid development of the low-cost laptop market. OLPC was undoubtedly the innovator in this category of low-cost laptops with their â€Å"$100 laptop† concept. However, now that for-profit companies have entered the market and released a slew of similar products, OLPC must find ways to maintain its competitive advantage. OLPC was facing some marketing challenges and some the non-marketing challenges. The $100 price for the laptops is to be achieved by operating with no profit, cutting all unnecessary frills including marketing campaigns and assembling large quantities of computers. Negroponte estimated the program will launch with a distribution of at least 5 million computers, and said he hopes to increase that number to 100 million by the second year. He predicted that as the laptop design improves, the per-unit price will go down. Marketing Challenges: †¢ Marketing a low-cost, lightweight laptop seemed contradictory to recent products that are lightweight and ultra-thin that were typically more expensive and harder to manufacture. †¢ Most children using $100 laptop would not have ready access to electricity. †¢ Consumers criticizing OLPC for discounting the value of teacher training and curriculum development using the device. †¢ Governments opting out to put its resources toward traditional method of education. †¢ Prices for the OLPC don’t seem to stay at $100 causing different price floats. †¢ Competition like Intel(for profit companies) launching its own cheaper laptop targeting developing nations as well. Offering enhanced capabilities and the ability to run version of Linux or Window XP 3. Analysis: Differentiation: Price and Technology OLPC should differentiate its product, the XO, from direct competitors such as Intel’s Classmate PC and indirect competitors in the netbook category such as Dell Mini product lines. Differentiation must be visible on three distinct levels; price, technology, and brand. Price: OLPC is currently the cost-leader in this category. The Intel Classmate PC, which is OLPC’s most direct competitor, is currently priced at $285. The OLPC’s XO is priced at $175. Since both OLPC and its competitors are serving government education programs, cost will be extremely important as a number of nations are creating bidding wars for purchasing contracts. Even though OLPC is the lowest cost offering at this point, maintaining this price advantage will become increasingly difficult as competition in the market for low-cost laptops heats up. OLPC overcame some of the challenges by keeping laptop at low-cost by outsourcing the major design work and key part of the operating systems to different countries. Technology and Innovation: OLPC had a first-mover advantage in this market as its XO offering was perhaps the first entrant into the affordable netbook category. OLPC is specialized for its market of children ages 6-12. The design and child-friendly operating system is very unique. The unique connectivity is important for rural areas with sparse communications infrastructure. The XO is built for ultimate adaptability. Even its power sources can be diversified. OLPC has done an admirable job differentiating its product from its competitors through its innovative technologies and education-specific software and hardware. Competitive Strategy: Though OLPC is a leader on price and feature set, sustaining this advantage will be extremely difficult when facing competition from the largest computer companies in the world. Thus to keep its top position, it must leverage its advantages as a non-profit organization. OLPC must create value from its non-profit status to build reputation and trust. As a non-profit, OLPC can build goodwill in ways that for-profit companies are not able. Also being a non-profit enables OLPC to finance and maintain pricing schemes that are different than the competition. In terms of cost savings, OLPC has the advantage that many companies are eager to produce components for the OLPC. For example, Microsoft has gone out of its way to create a version of Windows to run on the OLPC. This is a cost savings that competitive firms are unable to match. To exploit this advantage further, OLPC could even attract advertisement agency to advertise on their PCs to further lower the cost of each machine.

Reducing Aggregate Technical and Commercial Losses in the Power Sector

____________________________________________________________________________ 1.1 Introduction Power Sector is considered to be really of import and precedence sector as it leads to overall development of state. The cost of installing of new bring forthing units is lifting ; hence generated electrical energy has to be utilized carefully and expeditiously. One unit of electrical energy saved is tantamount to two unit ‘s electric energy generated.Ministry of Power, Govt. of India, has launched the Restructured Accelerated Power Development and Reforms Programme ( R-APDRP ) in the XI Five twelvemonth Plan. Power Finance Corporation Limited ( PFCL ) has been designated by GoIas the Nodal Agency for the programme.The programme spans from informations acquisition at distribution degree till monitoring of consequences of stairss taken to supply an IT anchor and strengthening of the Electricity Distribution system across the Country under the coder.

In add-on, normally used protocols and criterions are mentioned briefly IEC 61850 and UCA have assuring advantages over other protocols and will greatly alter SCADA systems today The protocols determine the effectivity of a SCADA system. Therefore, many protocols have been produced over the old ages to suit this demand. IEC 61850 with its self-description and security sweetenings has the most promising mentality in the protocol hereafter. It is a work-in-progress which should finally rule the electrical industry. 2.2 Review 2 Compartmentalization of Protocols in SCADA Communication: by- Dong-joo Kang and Rosslin John.Hongik University, Korea Department of Multimedia Engineering, Hannam University Ojeong-dong, Daeduk-gu, Daejeon, KoreaInternational Journal of Advanced Science and Technology Volume 8, July, 2009 mentioned In communicating, protocols are needed to be implemented to avoid some jobs. In the current province of SCADA communicating, two protocols are widely used, the T101 or IEC 60870-5-101 ( IEC101 ) and the DNP3 ( Distributed Network Protocol ) . In this paper, we present each protocol and discourse the specifications of T101 and DNP3. This can assist SCADA operators to choose which protocol is suited for the operations of their SCADA systems. IEC 60870-5-101/104 and DNP3 have fundamentally the same functionality, As discussed, DNP3 is popular in America. Since DNP3 and T101 are unfastened Standards, SCADA operators should supervise the development, and do parts when appropriate, to T101 and D NP3. They should besides prosecute the developers to include security characteristics on the protocols. SCADA communicating.

According to Shuman (2001), it is gradually becoming more and more difficult to reach a consensual working definition of what exactly is the internet. However, it can broadly be defined as a worldwide interconnection of thousands of separate computer networks. The Internet was originally developed in the 1960’s in the United States and it was intended to help link the country’s government agencies with various universities and colleges. However, the internet’s real expansion was first witnessed in the early years of the 1990’s when thousands of different companies as wel l as millions of individual persons realized that they could actually be able to easily afford the necessary telecommunication technology as well as the graphic browsers that are found to be vital in securing access to the internet as well as exchanging messages (Oggerino, 2001). Since its introduction, the internet has played a strategically vital role in revolutionizing communications and computers. The internet is found to serve multiple roles by acting as a mechanism through which information can be disseminated, a vast and intricate world-wide broadcasting capability as well as acting as a medium that allows interaction and collaboration between various computers and the individuals operating them all over the world regardless of their present geographical location (Betz, 2011). The Internet is widely...These benefits are seen to range from reduced advertisement costs for businesses, large market share and penetration to making it easier for business organization in general to be able to carry out cheaper and more effective market surveys. Customers are also able to experience several key benefits that are seen to result from the role played by the internet such as it is now relatively easier for customers to be able to make various purchases from their homes, they are also able quickly compare the price of a given commodity between different stores before making a purchase a factor which makes them gain more bargaining power. However there are several innate disadvantages that have been seen to affect both customers and businesses as a result of the role that the internet is seen to play. Some of these disadvantageous roles that are played by the internet are seen to include, increased risk of identity theft on the part of the customers and the common fact that business enterprises and especially so those in the entertainment industry are finding it increasingly difficult to adequately safeguard their intellectual properties (Fatayerji, 2004). Regardless of the specific role that the internet has been seen to have played that has impacted either customers or businesses, it’s continuous and general influence cannot be ignored and it is important for all business organizations and customers to ensure that they continuously evaluate it so as to effectively determine any advantages they stand to reap or the potential dangers resulting from the role played by the internet.

Chemistry Essay Example | Topics and Well Written Essays - 1000 words

Chemistry - Essay Example In this conformation there is no steric strain and no torsional strain. Due to the migration of electrons towards the more electronegative nucleus in a bond between two different elements the molecules become polarized. In larger molecules a number of poles form and this causes some parts of the molecule to attract and some to repel each other. In the butane molecule both ends of the molecule are rotating around the C-C bond and take different configurations (these are constantly changing. Steric strain is caused by the crowding together of groups – as explained above the groups are forced to approach each other till they touch, but because of their similar polarity they are under forces of repulsion also. This leads to the molecule possessing extra potential energy, this energy is called steric strain. a. In 1870, Markonikov laid down a basic principle of chemistry that holds till today. The Markonikov Rule states that when a hydrogen halide (Hydrochloric acid, HCl being an example) reacts with an asymmetrically substituted alkene the hydrogen attaches itself to the carbon atom that has the larger number of its hydrogen atoms substituted. The halogen automatically attaches itself to the carbon atom having the least number of its hydrogens substituted. An example of such an addition reaction: b. Enantiomers are two molecules of the same chemical that are the mirror image of each other, like our hands, they are similar but yet not the same and can not be superimposed on each other. Such molecules are called Enantiomers. They are not isomers and are not different from each other in any way except in their configuration. c. An Emperical formula gives the proportion of the constituent elements in the molecule but does not give the exact composition of the molecule. The empirical formula represents the mole fraction/ ratio of each element in the compound. For example the empirical formula may show that there is hydrogen and
