Let us suppose the maximum of range [i + 1, n - 1] is less than a[i], then we don't have any next greater element and we return - 1. Otherwise, check the left half and right half of the range [i + 1, n - 1]. If the maximum in left half ...

To build a SAT, first, an element is randomly selected as the root and the rest of the elements are sorted according to their distance to this root element. Then an element a is added as a child node to the root if a is closer to the root element than to the any already added ...
In votingkNN, thekneighbors are implicitly assumed to have equal weights in decisions, regardless of their distances to an instancexto be classified. It is intuitively appealing to give different weights to thekneighbors based on their distances tox, with closer neighbors having greater weights. ...
If the number of hairpins exceeds the expected dispersion of the NNTM model, it might be inferred that the greater number of hairpins is evidence of natural selection. The primary objective of the present study is to enable mathematical determination of the dispersion of RNA secondary structural...
First, pick a random element l uniformly from { 1 , 2 , 3 , 4 } . Now choose y as follows. If l = 1 , pick a random pair of consecutive symbols in X t , and call this pair s. If s is U D or H H , let s ′ be either U D or H H with probabilities 1 1 + e...
Since machine learning routines often push real-world limits of computing power, an exponential improvement to algorithm speed would allow for such systems with vastly greater capabilities [4]. Google’s ‘Quantum Supremacy’ experiment [5] showed that quantum computers can naturally solve specific ...
The height profile of 𝜏τ is the array 𝜌𝜏ρτ as an element of the quotient space of arrays of vectors under this equivalence relation. In other words, the vectors 𝜌𝜏(ℎ1,ℎ2)ρτ(h1,h2), 0≤ℎ2<ℎ10≤h2ℋ(𝜏)h1>H(τ). Consequently, the height profile can...
,N be a set of samples, where 𝐱𝑖∈ℝ𝑛xi∈Rn is an element (sample) of the dataset. Let us define d as a distance metric between any two samples in 𝒳X, and 𝑑𝑖𝑗=𝑑(𝐱𝑖,𝐱𝑗)dij=d(xi,xj). Let K be the number of nearest neighbors (NNs); then ...
