A random suffix search tree is a binary search tree constructed for the suffixes Xi = 0 · BiBi+1Bi+2… of a sequence B1, B2, B3, … of independent identically distributed random b-ary digits Bj. Let Dn denote the depth of the node for Xn in this tree when B1 is uniform on ℤ...

摘要: Let Hn be the height of a random binary search tree on n nodes. We show that there exist constants α = 4.311… and β = 1.953… such that E(Hn) = αln n − βln ln n + O(1), We also show that Var(Hn) = O(1).关键词:...
(Gaussian) distributed, where the so-called random permutationmodel was used as the model of randomness for the trees. This means thatevery permutation of length n is assumed to be equally likely when gener-ating a binary search tree; furthermore, for selecting nodes, allnodes are assumed to...
Another probabilistic tree model with respect to which the number of distinct fringe subtrees has been studied is thebinary search tree model: a random binary search tree of sizenis a binary search tree built by inserting the keysaccording to a uniformly chosen random permutation on. Random binar...
However, unlike RFs, ERTs build each tree from the complete learning sample without bootstrap and for each of the split candidates a discretization threshold is selected at random to define a split, instead of choosing the best cut-point based on the local sample. View chapter Book series ...
The root device progressively connects to all the network nodes in a Spanning Tree Protocol (STP) topology. It returns a cumulative attestation response for all the connected devices to the verifier. SMART (El Defrawy et al., 2012) is a hybrid remote attestation scheme designed for embedded ...
The new method uses bootstrap on each node during the tree creation process, instead of just bootstrapping once on the root node as in RF. This method, in turn, provides an ensemble of more diverse trees, allowing for more accurate predictions. Finally, for data where RF does not produce...

A model is inferred by applying a decision tree learning algorithm on a test plan of unknown quality, and running it against a high quality test plan (in the case of [110], a test plan of high strength). The quality assessment is based on the probability of misclassification of the ...
