Researchers have developed a new framework called Diffusion-Copula for probabilistic multivariate time series forecasting. This method explicitly separates the learning of individual asset behaviors from their complex interdependencies, addressing a common limitation in existing diffusion-based models that tend to underestimate extreme market risks. By employing Mixture Density Networks for marginal dynamics and a Classification-Diffusion Copula for dependence, the framework shows improved performance in forecasting extreme events in cryptocurrency markets, distinguishing between rare 'Black Swans' and predictable 'Expected Crashes' for better risk management.
