In the classification process used binary logistic regression, it obtained 77% predictive . accuration. The accuracy of binary logistic regression classification can be improved by using Adaptive Boosting (AdaBoost) method. In this study, the best classification by using Adaptive Boosting (AdaBoost) was obtained at 37. th. iteration with 91,33% ...

If there are K clusters, such a method would produce K scores; we thus fit a multiclass logistic regression model to the K scores as the final classifier using the R package nnet. Thus, to apply the classifier to an external dataset, one would need to calculate each cluster’s score, and then apply the multiclass logistic regression model to ...

Thus, we continued with Logistic Regression as our classification algorithm of choice. We use a multi-class classifier for our project. Figure 15 shows an example on how to use a Word2Vec model to transform a tweet into a feature vector and train a Logistic Regression classifier and save it into HDFS.

The purpose of this study is to develop a methodology for automatically classifying academic publication texts. The literature taxonomization process has been a critical element for understanding the development and evolution of knowledge and research areas in various disciplines (Brown et al. 1987, 1989, Vasarhelyi et al. 1988, Brinberg and Shields 1989, Meyer and Rigsby 2001, Heck and Jensen ...

This is a multiclass classification task. The task in this competition is to predict the type of iris plant using four attributes: sepal length, sepal width, petal length, and petal width. We randomly split the entire data into training and testing data, stratified on the target column
