Modeling and Simulation of Univariate and Multivariate analytics by applying Deep Learning and Machine Learning Application of Time Series application in the Neural Network Model.

The research addresses both univariate time series, where forecasts are made for a single variable over time, and multivariate time series, wherever multiple organized variables are used to develop predictive exactness. The data is split into training and testing sets by means of time series-specific practices such as sliding windows and expanding windows, confirming that chronological order is conserved and that models are authenticated effectually. Experimental consequences determine the applicability of deep learning models in accomplishing high accuracy for both short-term and long-term analytical tasks. The study compares the performance of univariate and multivariate tactics, highlighting the benefits of integrating multiple variables in refining forecast consistency (Adhikari and Ikeda, 2020). This research makes available a wide-ranging framework for applying machine learning and deep learning practices to time series prediction, offering insights into model selection, data preprocessing, and valuation approaches. The proposed approach validates substantial potential for real-world applications, enabling decision-makers to make informed forecasts and optimize procedures across various domains.
