The Elasticsearch vector retrieval plug-in is developed by Baidu Elasticsearch team, and can quickly realize vector retrieval, vector computation and other requirements. Background In recent years, the vector retrievals based on Text (Document) Embedding, eigenvector, etc. are widely applied in the...
Hence all eigenvalue-eigenvector pairs can be incorporated without causing a bottleneck in runtime. Consequently in VIA, the modified walk on a cluster-graph not only enables scalable pseudotime computation for large datasets in terms of runtime, but also preserves information about the global ...
A concrete example is finding the leading eigenvector of a covariance matrix \textbf{A}= \frac{1}{n} \sum _{i=1}^{n}\textbf{a}_i\textbf{a}_i^\top . Here, the objective can be structured as f_{{\varvec{b}}, \nu }(\textbf{x}) = \frac{1}{n}\sum _{i=1}^{n}(\...
It is a major goal in quantum thermometry to reach a 1/N scaling of thermometric precision known as Heisenberg scaling but is still in its infancy to date. The main obstacle is that the resources typically required are highly entangled states, which are
where, \({{W}_{i}}^{2}\) represents the squared eigenvector of the \({i}^{\mathrm{th}}\) workload and it produces a positive result in the computation of \(C(i)\). The values of the eigenvector range between 1 and \(n\) i.e., \(i=\{\mathrm{1,2},...n\}\). Th...
The eigenvector centrality 𝑥𝑖xi of node 𝑖i can be computed by the formula 𝐴𝑥=𝜆𝑥Ax=λx, where 𝐴A is the adjacency matrix of the graph, 𝑥x is the eigenvector corresponding to the largest eigenvalue 𝜆λ of matrix A, and 𝑥𝑖xi is the 𝑖i-th element of...

The numerical computation of the Jordan form is highly unstable, since a small perturbation suffices to obtain a matrix with different eigenvalues (and possibly a complete eigenvector system). Small angles between (some of) the eigenvectors reveal that A is close to a matrix that is similar to...
The study of evolutionary dynamics increasingly relies on computational methods, as more and more cases outside the range of analytical tractability are explored. The computational methods for simulation and numerical approximation of the relevant quanti
