Development of the classifier based on a multilayer perceptron using genetic algorithm and cart decision tree

Abstract

The problem of developing universal classifiers of biomedical data, in particular those that characterize the presence of a large number of parameters, inaccuracies and uncertainty, is urgent. Many studies are aimed at developing methods for analyzing these data, among them there are methods based on a neural network (NN) in the form of a multilayer perceptron (MP) using GA. The question of the application of evolutionary algorithms (EA) for setting up and learning the neural network is considered. Theories of neural networks, genetic algorithms (GA) and decision trees intersect and penetrate each other, new developed neural networks and their applications constantly appear. An example of a problem that is solved using EA algorithms is considered. Its goal is to develop and research a classifier for the diagnosis of breast cancer, obtained by combining the capabilities of the multilayer perceptron using the genetic algorithm (GA) and the CART decision tree. The possibility of improving the classifiers of biomedical data in the form of NN based on GA by applying the process of appropriate preparation of biomedical data using the CART decision tree has been established. The obtained results of the study indicate that these classifiers show the highest efficiency on the set of learning and with the minimum reduction of Decision Trees; increasing the number of contractions usually degrades the simulation result. On two datasets on the test set, the simulation accuracy was »83–87 %. The experiments carried out have confirmed the effectiveness of the proposed method for the synthesis of neural networks and make it possible to recommend it for practical use in processing data sets for further diagnostics, prediction, or pattern recognition

Analisis Bibliometrik Penelitian Pohon Keputusan untuk Prediksi Kanker Payudara

“…Metode ini telah diuji coba pada dataset kanker payudara dari UCI Machine Learning Repository dan terbukti efektif dalam mengatasi masalah tersebut (Tian & Zhang, 2022). Selain itu, sebuah studi menemukan bahwa metode Decision Tree sangat efektif dalam mendeteksi kanker payudara pada stadium awal dengan akurasi 100% pada uji coba pertama dan 97,9% pada uji coba kedua (Dobrovska & Nosovets, 2021).…”

A Hybrid Light Gradient Boosting Approach with Deep Boltzmann Machine for Intrusion Detection System

“…Several popular machine learning (ML) techniques for ID include Nave Bayes, the support vector machine (SVM), K-nearest neighbour (KNN), and neural networks. Classifier ensembles and single classifiers like CART and MLP [7] are evaluated using metrics and area under the receiver operating characteristic curve (AUC). IDS-ML offer a learning-based method for discovering attack classes based on learnt normal and attack behaviour.…”
