This document describes concisely the ubiquitous class of exponential family distributions met in statistics. The first part recalls definitions and summarizes main properties and duality with Bregman divergences (all proofs are skipped). The second part lists decompositions and related formula of common exponential family distributions. We recall the Fisher-Rao-Riemannian geometries and the dual affine connection information geometries of statistical manifolds. It is intended to maintain and update this document and catalog by adding new distribution items.

  1. Kalman Linear Attention: Parallel Bayesian Filtering For Efficient Language Modelling and State Tracking

    cs.LG 2026-02 conditional novelty 6.0

    KLA reparameterises information-form Kalman filtering as an associative Möbius scan, giving a parallelisable nonlinear state-space mixer that tracks A5 permutations with one or two layers.
