Predicting students' academic performance and modeling using data mining techniques

In educational institutions and universities, the issue of study interruptions can be addressed by using e-learning.  As a result, this field has recently attracted a lot of attention.  In this study, we applied four machine-learning methods to predict students' academic progress: logistic regression, decision trees, random forests, and Naive Bayes.  The Open University Learning Analytics Dataset (OULAD), which contains a subset of the OU student data, was the source of the student data for all of these techniques.  There is information regarding the students' VLE inter

This article reviews the theoretical aspects of logistic regression for binary data classification, including data preparation processes, training, testing, and model evaluation metrics.

Requirements for input data sets are formulated, methods of coding categorical data are described, methods of scaling input features are defined and substantiated.

Mathematical Model of Logistic Regression for Binary Classification. Part 1. Regression Models of Data Generalization

In this article, the mathematical justification of logistic regression as an effective and simple to implement method of machine learning is performed.

A review of literary sources was conducted in the direction of statistical processing, analysis and classification of data using the logistic regression method, which confirmed the popularity of this method in various subject areas.

Forecasting the Value of Real Estate Using Machine Learning Tools

Correct valuation of real estate plays a crucial role in the process of buying and selling. We have carefully studied the existing applications with which we carry out real estate transactions, described their features, advantages and disadvantages. The developed model will help sellers get an estimate of their property according to the parameters entered, which can serve as a starting point for establishing the final value.

Method of Identification of Combat Vehicles Based on Yolo

A method for recognizing contours of objects in a video data stream is proposed. Data will be uploaded using a video camera in real time and object recognition will be performed. We will use the YOLO network – a method of identifying and recognizing objects in real time. Recognized objects will be recorded in a video sequence showing the contours of the objects.

Methods of Machine Learning and Design of a System for Determining the Emotional Coloring of Ukrainian-language Content
