processes the input file“matrix.txt”with a factorization rank of4. The test of convergence will be performed each10iterations. If there are no relative differences in matrixHafter40consecutive convergence tests, the algorithm has converged. Otherwise, a maximum of2000iterations will be performed. ...
Input options include the selection of the factorization rank (k), the number of iterations to perform before testing for convergence, the maximum number of iterations in case data never converge to a stable solution, and the stopping threshold for a convergence test. The test of convergence comp...
The conclusions (Section 5) finally state that the automatic mineral identification in LWIR through the Clustering-rank11 NMF algorithm has lower computational complexity but considerable better accuracy as compared to the FCC-Clustering algorithm and that fulfills the objectives of this research. 2. ...
Then, the first rank of Non-negative Matrix Factorization (NMF) extracts the representative of each cluster and compares results with the spectral library of JPL/NASA. We compare these two strategies of clustering to identify minerals in hyperspectral imagery. This is the first time such a ...

The compression ratio of the NMF method only depends on the size of the rank of the base matrix. Therefore, compression ratio can be adaptively adjusted to the energy consumption demands. When a node's energy depleted, we can choose a lower quality to improve the compression ratio in order ...
