Learning Monotone Decision Trees in Polynomial Time
We give an algorithm that learns any monotone Boolean function f : {-1, 1}n {-1, 1} to any constant accuracy, under the uniform distribution, in time polynomial in n and in the de...

Merkle Tree Traversal in Log Space and Time
Abstract. We present a technique for Merkle tree traversal which requires only logarithmic space and time1 . For a tree with N nodes, our algorithm computes sequential tree leaves ...

Structure from Statistics - Unsupervised Activity Analysis using Suffix Trees
Models of activity structure for unconstrained environments are generally not available a priori. Recent representational approaches to this end are limited by their computational...
