A linear time algorithm for smallest augmentation to 3-edge-connect a graph - Watanabe, Yamakado - 1993 () Citation Context ...ly summarize known results on kECA-SVDC. Concerning kECA, several polynomial time algorithms have been shown. Eswaran and Tarjan [1] proposed an O(|V| + |E|)...
Ideally, linear algebra software would detect structure in a matrix and call an algorithm that exploits that structure. A notable example of such a meta-algorithm is the MATLAB backslash functionx = A\bfor solving . Backslash checks whether the matrix is triangular (or a permutation of a trian...

This approach is often useful when the system of equations arises as part of a general algorithm, and you do not know in advance how many variables will be involved. A system of linear equations can be stated in matrix form as , where is the vector of variables. ...
If the jump in values of f is above a certain threshold for a given time interval, the binary feature is unreliable in this interval. The threshold necessary to detect the unreliable features is not static and is determined by a dynamic thresholding algorithm. Harville et al. in [115] ...

Here's a simple gradient descent algorithm for LAE-PCA with untied weights (i.e. there is no constraint on W1 or W2): XXt = X @ X.T while np.linalg.norm(W1 - W2.T) > epsilon: W1 -= alpha * ((W2.T @ (W2 @ W1 - I)) @ XXt + lamb * W1) W2 -= alpha * (((W2 @...
With simplex algorithm in “lp_solve”, the average time cost to solve Eq. (9) is O(m1.5)∼O(m2), where m is the number of variables [54]. Since the DML is based on SVD, so the total time cost of DML is O(rn2+nd+(m1.5∼m2)). In Nyström method, the time cost ...
For algorithm 1: if x \le \varepsilon/2, then fl(1+x)=1, then \log(1+x)=0, so result is 0. When \varepsilon/2 < x\ll 1, then \begin{aligned} &fl(1+x)=(1+x)(1+\delta_1)=1+x+\delta_1+\delta_1x\\ &fl(\frac{\log(1+x)}{x})=fl(\frac{\log(1+x+\delta...
Profilingallows a more detailed analysis of the execution of the algorithm. We observe that most of the execution time is spent in thelstsqsolver of scipy. The profiling reports of sklearn_benchmarks can be viewed withPerfetto UI. See benchmark environment information ...
