Survey of Machine Learning Algorithms for Disease Diagnostic

In medical imaging, Computer Aided Diagnosis (CAD) is a rapidly growing dynamic area of research. In recent years, significant attempts are made for the enhancement of computer aided diagnosis applications because errors in medical diagnostic systems can result in seriously misleading medical treatments. Machine learning is important in Computer Aided Diagnosis. After using an easy equation, objects such as organs may not be indicated accurately. So, pattern recognition fundamentally involves learning from examples. In the field of bio-medical, pattern recognition and machine learning promise the improved accuracy of perception and diagnosis of disease. They also promote the objectivity of decision-making process. For the analysis of high-dimensional and multimodal bio-medical data, machine learning offers a worthy approach for making classy and automatic algorithms. This survey paper provides the comparative analysis of different machine learning algorithms for diagnosis of different diseases such as heart disease, diabetes disease, liver disease, dengue disease and hepatitis disease. It brings attention towards the suite of machine learning algorithms and tools that are used for the analysis of diseases and decision-making process accordingly.


Introduction
Artificial Intelligence can enable the computer to think.Computer is made much more intelligent by AI.Machine learning is the subfield of AI study.Various researchers think that without learning, intelligence cannot be developed.There are many types of Machine Learning Techniques that are shown in Figure 1.Supervised, Unsupervised, Semi Supervised, Reinforcement, Evolutionary Learning Classification: It gives the prediction of Yes or No, for example, "Is this tumor cancerous?","Does this cookie meet our quality standards?"Regression: It gives the answer of "How much" and "How many".
2) Unsupervised learning: Correct responses or targets are not provided.Unsupervised learning technique tries to find out the similarities between the input data and based on these similarities, un-supervised learning technique classify the data.This is also known as density estimation.Unsupervised learning contains clustering [1].
Clustering: it makes clusters on the basis of similarity.
3) Semi supervised learning: Semi supervised learning technique is a class of supervised learning techniques.This learning also used unlabeled data for training purpose (generally a minimum amount of labeled-data with a huge amount of unlabeled-data).Semi-supervised learning lies between unsupervised-learning (unlabeled-data) and supervised learning (labeled-data).4) Reinforcement learning: This learning is encouraged by behaviorist psychology.Algorithm is informed when the answer is wrong, but does not inform that how to correct it.It has to explore and test various possibilities until it finds the right answer.It is also known as learning with a critic.It does not recommend improvements.Reinforcement learning is different from supervised learn-ing in the sense that accurate input and output sets are not offered, nor suboptimal actions clearly précised.Moreover, it focuses on on-line performance.5) Evolutionary Learning: This biological evolution learning can be considered as a learning process: biological organisms are adapted to make progress in their survival rates and chance of having off springs.By using the idea of fitness, to check how accurate the solution is, we can use this model in a computer [1].proper means to extract and process data effectively and efficiently [3].One of the many machine-learning applications is employed to build such classifier that can divide the data on the basis of their attributes.Data set is divided into two or more than two classes.Such classifiers are used for medical data analysis and disease detection.
Initially, algorithms of ML were designed and employed to observe medical data sets.Today, for efficient analysis of data, ML recommended various tools.
Especially in the last few years, digital revolution has offered comparatively lowcost and obtainable means for collection and storage of data.Machines for data collection and examination are placed in new and modern hospitals to make them capable for collection and sharing data in big information systems.Technologies of ML are very effective for the analysis of medical data and great work is done regarding diagnostic problems.Correct diagnostic data are presented as a medical record or reports in modern hospitals or their particular data section.To run an algorithm, correct diagnostic patient record is entered in a computer as an input.Results can be automatically obtained from the previous solved cases.Physicians take assistance from this derived classifier while diagnosing novel patient at high speed and enhanced accuracy.These classifiers can be used to train nonspecialists or students to diagnose the problem [4].
In past, ML has offered self-driving cars, speech detection, efficient web search, and improved perception of the human generation.Today machine learning is present everywhere so that without knowing it, one can possibly use it many times a day.A lot of researchers consider it as the excellent way in moving towards human level.The machine learning techniques discovers electronic health record that generally contains high dimensional patterns and multiple data sets.Pattern recognition is the theme of MLT that offers support to predict and make decisions for diagnosis and to plan treatment.Machine learning algorithms are capable to manage huge number of data, to combine data from dissimilar resources, and to integrate the background information in the study [3].

Liver Disease
Vijayarani and Dhayanand [17] predict the liver disease by using Support vector A study on intelligent techniques to classify the liver patients is performed by the Gulia et al. [18].Used data set is picked up from UCI. WEKA data mining tool and five intelligent techniques J48, MLP, Random Forest, SVM and Bayesian Network classifiers are used in this experiment.In first step, all algorithms are applied on the original data set and get the percentage of correctness.In second step, feature selection method is applied on whole data-set to get the significant subset of liver patients and all these algorithms are used to test the subset of whole data-set.In third step they take comparison of outcomes before and after feature selection.After FS, algorithms provide highest accuracy as J48 presents 70.669% accuracy, 70.8405% exactness is achieved by the MLP algorithm, SVM provides 71.3551% accuracy, 71.8696% accuracy is offered by Random forest and Bayes Net shows 69.1252% accuracy.Rajeswari and Reena [19] used the data mining algorithms of Naive Bayes, K star and FT tree to analyze the liver disease.Data set is taken from UCI that comprises of 345 instances and 7 attributes.10 cross validation test are applied by using WEKA tool.Naive Bayes provide 96.52% Correctness in 0 sec.97.10% accuracy is achieved by using FT tree in 0.2 sec.K star algorithm classify the instances about 83.47% accurately in 0 sec.On the basis of outcomes, highest classification accuracy is offered by FT tree on liver disease dataset as compared to other data mining algorithms.Table 3 presents the comprehensive view of algorithms for the detection of liver disease. Analysis: To diagnose liver disease, FT Tree Algorithm provides the highest result as compare to the other algorithms.When FT tree algorithm is applied on the dataset of liver disease, time taken for result or building the model is fast as compared to other algorithms.According to its attribute, it shows the improved performance.This algorithm fully classified the attributes and offers 97.10% correctness.From the results, this Algorithm plays an important role in determining enhanced classification accuracy of data set.Accuracy graph of algorithms are shown in Figure 5.

Conclusion
Statistical models for estimation that are not capable to produce good performance results have flooded the assessment area.Statistical models are unsuccessful to hold categorical data, deal with missing values and large data points.
All these reasons arise the importance of MLT.ML plays a vital role in many applications, e.g.image detection, data mining, natural language processing, and disease diagnostics.In all these domains, ML offers possible solutions.This paper provides the survey of different machine learning techniques for diagnosis of different diseases such as heart disease, diabetes disease, liver disease, dengue and hepatitis disease.Many algorithms have shown good results because they identify the attribute accurately.From previous study, it is observed that for the detection of heart disease, SVM provides improved accuracy of 94.60%.Diabetes disease is accurately diagnosed by Naive Bayes.It offers the highest classification accuracy of 95%.FT provides 97.10% of correctness for the liver disease diagnosis.For dengue disease detection, 100% accuracy is achieved by RS theory.The feed forward neural network correctly classifies hepatitis disease as it provides 98% accuracy.Survey highlights the advantages and disadvantages of these algorithms.Improvement graphs of machine learning algorithms for prediction of diseases are presented in detail.From analysis, it can be clearly observed that these algorithms provide enhanced accuracy on different diseases.This survey paper also provides a suite of tools that are developed in community of AI.These tools are very useful for the analysis of such problems and also provide opportunity for the improved decision making process.
