Learning Binary Latent Variable Models: A Tensor Eigenpair Approach
Ariel Jaffe, Roi Weiss, Shai Carmi +2
Latent variable models with hidden binary units appear in various applications. Learning such models, in particular in the presence of noise, is a challenging computational problem…
A note on the distribution of admixture segment lengths and ancestry proportions under pulse and two-wave admixture models
Shai Carmi, James Xue, Itsik Pe'er
Admixed populations are formed by the merging of two or more ancestral populations, and the ancestry of each locus in an admixed genome derives from either source. Consider a simpl…
The SMC' is a highly accurate approximation to the ancestral recombination graph
Peter R. Wilton, Shai Carmi, Asger Hobolth
Two sequentially Markov coalescent models (SMC and SMC') are available as tractable approximations to the ancestral recombination graph (ARG). We present a Markov process describin…
A renewal theory approach to IBD sharing
Shai Carmi, Peter Wilton, John Wakeley +1
A long genomic segment inherited by a pair of individuals from a single, recent common ancestor is said to be identical-by-descent (IBD). Shared IBD segments have numerous applicat…
Random walk with priorities in communication-like networks
Nikolaos Bastas, Michalis Maragakis, Panos Argyrakis +3
We study a model for a random walk of two classes of particles (A and B). Where both species are present in the same site, the motion of A's takes precedence over that of B's. The…
The variance of identity-by-descent sharing in the Wright-Fisher model
Shai Carmi, Pier Francesco Palamara, Vladimir Vacic +3
Widespread sharing of long, identical-by-descent (IBD) genetic segments is a hallmark of populations that have experienced recent genetic drift. Detection of these IBD segments has…
