Enhancing Financial Risk Prediction Using TG-LSTM Model: An Innovative Approach with Applications to Public Health Emergencies

Amidst the backdrop of economic globalization and occasional public health crises, the comprehension and mitigation of financial risks confronting enterprises have emerged as imperative pursuits. This research paper delves into the intricate nexus between these global phenomena and the realm of financial risk management. Conventional approaches to financial risk prediction often falter in grappling with the intricacies of contemporary financial markets. To address this challenge, our study introduces a pioneering methodology termed the TG-LSTM (Time Series Ratio Analysis combined with Long Short-Term Memory) model, aimed at furnishing early financial warnings to enterprises. The TG-LSTM model harnesses the power of ratio analysis to discern representative financial data reflective of crucial facets such as debt-paying ability, operational efficiency, growth prospects, and profitability. Leveraging the TSVD (Truncated Singular Value Decomposition) technique bolsters prediction accuracy, while the XGboost feature screening method aids in curtailing data dimensionality. Our analysis integrates real-world data from the CSI 300 and SSE 50 datasets, with results showcasing the efficacy of the TG-LSTM model. With the lowest Root Mean Square Error (RMSE), Mean Absolute Error (MAE), and Mean Absolute Percentage Error (MAPE) values, our model attains an impressive accuracy rate of 96.1
