Generally, in the text classification task, a document is expressed as a vector of many dimensions, x = (x1, x2,…,xl). WEKA software will be used for the classification as a tool. It is an open source program developed by the University of New Zealand. Algorithms can be applied either directly or to a dataset called from own java code. The purpose of this research is to put together the 7 most common types of classification algorithms along with the python code: Logistic Regression, Naïve Bayes, Stochastic Gradient Descent, K-Nearest Neighbours, Decision Tree, Random Forest, and Support Vector Machine. Weka is designed to be a high-speed system for classification, and in some areas, the design deviates from the expectations of a traditional object-oriented system. Classification Algorithms used in the Experiment The analysis of the algorithm's results on medical datasets showed that it can be successfully used for data classification . Found only on the islands of New Zealand, the Weka is a flightless bird with an inquisitive nature. classification techniques WEKA tool. In the rest of this section, some properties of WEKA software and ten classification algorithms used in this paper are summarized. Weka, which is short for Waikato Environment for Knowledge Analysis, is a machine learning library developed at the University of Waikato, New Zealand, and is probably the most well-known Java library. Weka's implementation of C4.5 (and its precursor ID3) is called J48.J is for Java (and 48 is for 1998, or it is just some increment, I don't know). are using Weka because it helps us to evaluate the result of the classification. The algorithms can either be applied directly to a dataset or called from your own Java code. Let us examine the output shown on the right hand side of the screen. weka→classifiers>trees>J48. In total there are 19 classifiers explained in this paper and the three best or efficient classifiers have been evaluated by three different authors as . of Weka's software are predicated on the assumption that the data is available as a single flat file or relation, where each data point is described by a fixed number of attributes attribute types are also supported).
