AI & MACHINE LEARNING FOR TRUSTED INFORMATION
A Hybrid Deep Learning Framework for Fake News Detection Using LSTM-CGPNN and Metaheuristic Optimization
In recent years, the widespread dissemination of fake news on social media has raised concerns about its impact on public opinion, trust, and decision-making. Addressing the limitations of traditional detection methods, this study introduces a hybrid deep learning approach that enhances the identification of fake news. The objective is to improve detection accuracy and model robustness by combining a Long Short-Term Memory (LSTM) network for contextual feature extraction with a Convolutional Gaussian Perceptron Neural Network (CGPNN) for classification. To further optimize performance, we integrated a metaheuristic Moth-Flame Whale Optimization (MFWO) algorithm for hyperparameter tuning.
Executive Impact Summary
Our hybrid framework offers unparalleled accuracy and robustness in identifying deceptive content, demonstrating significant improvements over existing state-of-the-art methods across diverse social media datasets. This translates into more reliable information environments and stronger trust.

Balanced Error Distribution for Trustworthy Systems
Our model's balanced performance across false positive and false negative errors ensures its practical utility. This means it avoids strong bias toward either misclassifying authentic news as fake (false positive) or failing to detect actual fake news (false negative). This equilibrium is crucial for maintaining public trust and avoiding unintended consequences in real-world deployments.
For example, in social media monitoring, a system with balanced errors would prevent both censorship of legitimate news and the unchecked spread of harmful misinformation, fostering a healthier information ecosystem.
