New algorithm improves multi-agent forecasting with sublinear swap regret

Researchers have developed a new forecasting algorithm designed to minimize swap regret for multiple downstream agents with unknown objectives. For two-dimensional outcome spaces, the algorithm achieves a regret bound of $\tilde{O}(\sqrt{kT})$, an improvement over previous bounds and runtimes. The approach extends to higher dimensions, offering a $\tilde{O}(d\sqrt{kT})$ swap regret guarantee in arbitrary dimensions, which is more efficient and requires fewer assumptions than prior high-dimensional methods.
