Hybrid least squares support vector machine for water level forecasting

Previous studies have highlighted the significant role of historical water level data in flood forecasting.  In this study, we compare two standalone models, Support Vector Machine (SVM) and Least Squares Support Vector Machine (LSSVM), with hybrid models that integrate Ensemble Empirical Mode Decomposition (EEMD) with SVM and LSSVM, aiming to develop a more effective forecasting approach for hydrological data.  Particle Swarm Optimization (PSO) is incorporated into these hybrid models to optimize the parameters of SVM and LSSVM, resulting in four models: SVM-PSO, LSSVM

MODELS FOR TIME SERIES FORECASTING USING ARIMA AND LSTM IN ECONOMICS AND FINANCE

Time series forecasting is a crucial task in economics, business, and finance. Traditionally, forecasting methods such as autoregression (AR), moving average (MA), exponential smoothing (SES), and, most commonly, the autoregressive integrated moving average (ARIMA) model are used. The ARIMA model has demonstrated high accuracy in predicting future time series values. With the advancement of computational power and deep learning algorithms, new approaches to forecasting have emerged.

METHODOLOGY FOR IMPLEMENTING SELF-LEARNING FEEDBACK MODELS IN CRM SYSTEMS: COMPARATIVE ANALYSIS OF EFFECTIVENESS

DECISION SUPPORT SYSTEM FOR DISINFORMATION, FAKES AND PROPAGANDA DETECTION BASED ON MACHINE LEARNING

Due to the simplification of the processes of creating and distributing news via the Internet, as well as due to the physical impossibility of checking large volumes of information circulating in the network, the volume of disinformation and fake news distribution has increased significantly. A decision support system for identifying disinformation, fakes and propaganda based on machine learning has been built. The method of news text analysis for identifying fakes and predicting the detection of disinformation in news texts has been studied.
