New method improves learning of discrete distribution parameters

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method for efficiently learning the natural parameters of discrete distributions from samples within a specific subset. This approach refines existing guarantees under a 'fatness' assumption, improving sample complexity to O(log n / ε^2) for l∞-recovery. The method generalizes the 'fatness' concept using influence analysis for Boolean functions, providing sufficient conditions for efficient inference without requiring sampling at arbitrary parameterizations. A theoretical lower bound was also established, showing an intrinsic exponential dependence on model width and minimum element distance. AI

    Efficient Learning of Truncated Boolean Product Distributions: Influence to the Rescue

    arXiv:2607.22889v1 Announce Type: cross Abstract: Learning the natural parameters $z \in \mathbb{R}^n$ of discrete distributions $\mu_z$ from independent samples constrained to a subset $S \subseteq \{0,1\}^n$ is a foundational challenge in high-dimensional statistics. Existing m…
