WebJun 19, 2009 · Assumption made is T1 and T2 are binary tree without any balancing factor. 1) Search the root of T2 in T1. If not found T2 is not a subtree. Searching the element in BT will take O (n) time. 2) If the element is found, do pre-order traversal of T1 from the node root element of T2 is found. This will take o (n) time. WebA prefix hash tree (PHT) is a distributed data structure that enables more sophisticated queries over a distributed hash table (DHT). [citation needed] The prefix hash tree uses the lookup interface of a DHT to construct a trie-based data structure that is both efficient (updates are doubly logarithmic in the size of the domain being indexed), and resilient …

WebFor tree-based models, a new notion, \emph{confounding entropy}, is proposed to measure the discrepancy introduced by unobserved confounders between the conditional outcome distribution of the treated and control groups. The confounding entropy generalizes conventional confounding bias, and can be estimated effectively using historical controls.
