Due to to the high rate of colon cancer and the benefits of data mining to predict survival, the aim of this study was to survey two widely used machine learning algorithms, Bagging and Support Vector Machines (SVM), to predict the outcome of colon cancer patients. Therefore, this research aims to conduct comparative evaluation between four classifiers which are Deep Neural Network (DNN), Random Forest (RF), Support Vector Machine (SVM) and Decision Tree (DT). Classification is the creation of classes that represent users and use cases. Classification techniques are widely used in enterprise organizations. In this paper, we present a new fast heuristic for building decision trees from large training sets, which overcomes some of the restrictions of the state of the art algorithms, using all the instances of the training set without storing all of them in main memory. Support vector machines (SVMs) have been promising methods for classification and regression analysis because of their solid mathematical foundations which convery several salient properties that other methods hardly provide. limitations. The accuracy, specificity, and sensitivity of the SVM was 84.48%, 81%, and 87%, and the accuracy, specificity, and sensitivity of Bagging was 83.95%, 78%, and 88%, respectively. ... Decision Trees employ decision logic easy for human understanding and as such they are described as white box models.

In attempt to address this concern, UN Global Pulse demonstrated that tweets reporting food prices from Indonesians can aid in predicting actual food price increase. As prediction models are trained for each stock futures contract, it is necessary to employ high performance algorithms. For regions like Kenya and Uganda where use of tweets is considered low, this option can be problematic. The classification model is trained from the labelled data. There exist various ways by which classification can be achieved in a supervised or unsupervised manner. This paper presents a stock futures prediction strategy by using a hybrid method to forecast the price trends of the futures which is essential for investment decisions. The age and emotion detection method adopted employs extraction of basic prosodic and spectral feature from the emotional speech corpuses and uses Support Vector Machine (SVM) algorithm for classification. of feature sets, it is essential to understand dataset beforehand. Addressing big data is a challenging and time-demanding task that requires a large computational infrastructure to ensure successful data processing and … Three hundred and thirty eight patients were alive and 229 patients were dead. All these classifiers have its own efficiency and have an important role in identifying the set of populations based on the training datasets. unsupervised.

This study used education case study on student’s performance data for two subjects, Mathematics and Portuguese from two Portugal secondary schools and data on the student's knowledge of Electrical DC Machines subject. Applying existing AC approaches on such high dimensional datasets produce some limitations in terms of both computational complexity and memory requirements [ 15 ]. Big Data is a new buzzword used to refer to the techniques used to face up the problems arising from the management and analysis of these huge quantities of data [ 14 ]. The data are first stored in a distributed database. They are as follow, BayesNet, NaiveBayes, Multilayer perceptron and J48. There are three types of algorithms in machine learning that can be used for Big Data classification – Supervised, semi-supervised and unsupervised.
