Temporal Relational Reasoning of Large Language Models for Detecting Stock Portfolio Crashes

no code implementations7 Oct 2024 Kelvin J. L. Koa, Yunshan Ma, Ritchie Ng, Huanhuan Zheng, Tat-Seng Chua

Stock portfolios are often exposed to rare consequential events (e. g., 2007 global financial crisis, 2020 COVID-19 stock market crash), as they do not have enough historical information to learn from.

Learning to Generate Explainable Stock Predictions using Self-Reflective Large Language Models

1 code implementation6 Feb 2024 Kelvin J. L. Koa, Yunshan Ma, Ritchie Ng, Tat-Seng Chua

The training samples for the PPO trainer are also the responses generated during the reflective process, which eliminates the need for human annotators.

Diffusion Variational Autoencoder for Tackling Stochasticity in Multi-Step Regression Stock Price Prediction

1 code implementation18 Aug 2023 Kelvin J. L. Koa, Yunshan Ma, Ritchie Ng, Tat-Seng Chua

The hierarchical VAE allows us to learn the complex and low-level latent variables for stock prediction, while the diffusion probabilistic model trains the predictor to handle stock price stochasticity by progressively adding random noise to the stock data.
