Center node: "learning balanced mixtures of discrete distributions with small sample"
  Abstract: We study the problem of partitioning a small sample of n individuals from a mixture of k product distributions over a Boolean cube {0, 1} K according to their distributions. Each distribution is des cribed by a vector of allele frequencies in R K . Given two distributions, we use γ to denote the average l 2 distance in frequencies across K dimensions, which measures the statistical divergence between them. We study the case assuming that bits are independently distributed acro ss K dimensions. This work demonstrates that, for a balanced input instance for k = 2, a certain graph-based optimization function returns the correct partition with high probability, where a weighted graph G is formed over n individuals, whose pairwise hamming distances between their corresponding bit vectors define th e edge weights, so long as K =  (ln n/γ ) and K n = ˜  ln n/γ 2 � . The function computes a maximum-weight balanced cut of G, where the weight of a cut is the sum of the weights across all edges in the cut. This r esult demonstrates a nice property in the high-dimensional feature space: one can trade off the number of features that are required with the size of the sample to accomplish certain tasks like clustering.
