aFor more theoretical background on spectral clustering, such as how affinity matrices are computed, the different types of graph Laplacians, and whether the top or bottom eigenvectors and eigenvalues are computed, please read Ulrike von Luxburg's article in Statistics and Computing from December 20...
Cluster analysis can be a powerful data-mining tool to identify discrete groups of customers, sales transactions, or types of behaviours.
We show that U λ is a self-similar set satisfying the open set condition if and only if U λ can tile an interval by finitely many of its affine copies (admitting different dilations). Furthermore, each such λ can be characterized as the spectrum of an irreducible double word which ...

density peaks. These instances are used to generate a new data matrix with label-specific features. On the other hand, we train a paired output prediction network for each label based on these matrices of its own and that of two auxiliary labels. In this way, we are essentially considering...
The prompt memory use should be reduced a lot by flash attention Metal shaders for memory efficient self attention on large sequences mlx#964 to avoid materializing the full N^2 score matrices The generation is kind of adversarial for our memory cache since we grow the memory requirement for ...
I do not mean I consider using C/C++ better, but I'm interested whether people use Fortran nowadays just because of plenty scientific legacy codes or there are other reasons due to which Fortran is better than C at some point. As far as I ...
To do so, the training data are commonly transferred into a sparse-matrix format (Wong, Liu, & Chiang, 2014) called document-term matrix (DTM). DTMs are one possible implementation (among others such as, e.g., set implementations which do not rely on matrices) of bag-of-words ...
The sepsis (and non-sepsis) class profiles created from these 10 anchors by MSC, MSC-RF, MSC-LSTM models, respectively are also displayed. While the profiles for each class for both hybrid models look similar, they differ significantly from the sepsis profiles obtained from MSC. Full size ...
