modified Gram-Schmidt (MGS) algorithmrandom hidden nodesExtreme learning machine (ELM) has shown to be extremely fast with better generalization performance. The basic idea of ELM algorithm is to randomly choose the parameters of hidden nodes and then use simple generalized inverse operation to solve...
R[k][k]=||tmpk|| cQk=tmpk/R[k][k] Q calculated by Classical Gram Schmidt algorithm is not very orthogonal due to rounding errors. An example is provided by X. Jiao[1] The error introduced in q1 also cause errors in q2 and q3. We will discuss how to avoid this in the next ...
It is easy to show, however, that the Classical approach can be programmed in such a way that the numerical stability is the same as that produced by Modified Gram-Schmidt, which is to say that the Gram-Schmidt process can be modified so that the results on the computer are the same ...
An example of Gram Schmidt Orthogonalisation: Find one orthonormal set of R^3 given vectors (1,1,0)^T,(-1,1,1)^T,(1,-1,0)^T These vectors can be organized in a data matrix A: We denote in this article the k-th column of a matrix A by cAk. Similarly we shall use rAj to...
We have proposed the hyperbolic modified Gram–Schmidt method and its stabilized version for block downdating the Cholesky factorization. The stabilized MGS-based (SMGS) method has been proven to be mixed stable and can give more accurate results than the stabilized Householder-based algorithm when ...
A modified Gram-Schmidt QR decomposition core implemented in a single field programmable gate array (FPGA) comprises a converter configured to convert a complex fixed point input to a complex floating point input, dual port memory to hold complex entries of an input matrix, normalizer programmable ...
