A Novel Optimized Method for Feature Selection Using Non-linear Kernel-Free Twin Quadratic Surface Support Vector Machine

Maity, Saptashwa.; Rastogi, Arjav.; Djeddi, Chawki.; Sarkar, Sobhan.; Maiti, J. (Springer, 2022-04-13)

Feature Selection (FS) is an important topic in the domain of machine learning. Support Vector Machine (SVM) is one of the most popular ML models for classification tasks. Efficient feature selection may ensure enhanced ...
Trees with matrix weights: laplacian matrix and characteristic-like vertices

Ganesh, Swetha.; Mohanty, Sumit. (Linear Algebra and its Applications, 2022-08)

It is known that there is an alternative characterization of characteristic vertices for trees with positive weights on their edges via Perron values and Perron branches. Moreover, the algebraic connectivity of a tree with ...
