Researchers have demonstrated a method to simplify the Information Bottleneck (IB) problem by reducing it to a lower-dimensional equivalent when a sufficient statistic exists. This reduction is lossless, preserving the entire IB curve and optimal representations. The approach significantly decreases computational complexity, making the IB problem tractable under specific structural conditions and bridging discrete and linear-Gaussian settings. AI
