The Stirling polynomials σn(x) are related to the Bernoulli numbers by Bn = n!σn(1). S. C. Woon described an algorithm to compute σn(1) as a binary tree: Woon's recursive algorithm (for n ≥ 1) starts by assigning to the root node N = [1,2]. Given a node N = [a1, a2, ..., ak] of the tree, the left child of the node is L(N) = [−a1, a2 + 1, a3, ..., ak] and the right child R(N) = [a1, 2, a2, ..., ak]. A node N = [a1, a2, ..., ak] is written as ±[a2, ..., ak] in the in… WebApr 10, 2024 · Binary Latent Diffusion. In this paper, we show that a binary latent space can be explored for compact yet expressive image representations. We model the bi-directional mappings between an image and the corresponding latent binary representation by training an auto-encoder with a Bernoulli encoding distribution.
