Abstract

Predictive financial modeling plays a critical role in supporting decision-making across financial markets, including applications in asset pricing, risk management, credit scoring, and market forecasting. Traditional econometric models and classical machine learning techniques, while useful, often struggle to capture the nonlinear, high-dimensional, and dynamic nature of financial data. In recent years, the emergence of deep learning has provided powerful tools for modeling complex financial patterns. This explores the application of hybrid deep learning architectures in predictive financial modeling, focusing on models that integrate multiple neural network structures such as Convolutional Neural Networks (CNN), Long Short-Term Memory networks (LSTM), and attention mechanisms. Hybrid models are designed to leverage the strengths of different learning architectures, such as CNN’s capability for local feature extraction and LSTM’s ability to capture long-term temporal dependencies. These integrated models are increasingly used for diverse financial prediction tasks, including stock price forecasting, credit risk assessment, and market volatility estimation. This reviews key hybrid architectures such as CNN-LSTM, LSTM with attention mechanisms, and autoencoder-enhanced models, highlighting their ability to improve predictive accuracy and model robustness when dealing with noisy and volatile financial datasets. Additionally, this examines methodological considerations, including data preprocessing, model validation, and performance metrics such as Root Mean Squared Error (RMSE) and Mean Absolute Error (MAE). Despite their advantages, hybrid deep learning models face challenges such as high computational complexity, risk of overfitting, and limited interpretability. This concludes by emphasizing the growing importance of explainable AI, real-time adaptive learning, and domain-specific model development for future research. Ultimately, hybrid deep learning architectures offer a promising direction for enhancing predictive accuracy and decision-making in financial markets, with significant implications for investors, financial institutions, and regulators alike.
