AMA-LSTM: Pioneering Robust and Fair Financial Audio Analysis for Stock Volatility Prediction
This addresses robustness and fairness issues in financial audio analysis for stock volatility prediction, though it appears incremental as it builds on existing adversarial training techniques.
The paper tackled unreliable and gender-biased multimodal models for stock volatility prediction by using adversarial training to generate perturbations that simulate stochasticity and bias, improving robustness and fairness; experiments on two real-world financial audio datasets showed it outperforms current state-of-the-art methods.
Stock volatility prediction is an important task in the financial industry. Recent advancements in multimodal methodologies, which integrate both textual and auditory data, have demonstrated significant improvements in this domain, such as earnings calls (Earnings calls are public available and often involve the management team of a public company and interested parties to discuss the company's earnings). However, these multimodal methods have faced two drawbacks. First, they often fail to yield reliable models and overfit the data due to their absorption of stochastic information from the stock market. Moreover, using multimodal models to predict stock volatility suffers from gender bias and lacks an efficient way to eliminate such bias. To address these aforementioned problems, we use adversarial training to generate perturbations that simulate the inherent stochasticity and bias, by creating areas resistant to random information around the input space to improve model robustness and fairness. Our comprehensive experiments on two real-world financial audio datasets reveal that this method exceeds the performance of current state-of-the-art solution. This confirms the value of adversarial training in reducing stochasticity and bias for stock volatility prediction tasks.
