A survey of kernel and spectral methods for clustering [PDF]
, 2007 Clustering algorithms are a useful tool to explore data structures and have been employed in many disciplines. The focus of this paper is the partitioning clustering problem with a special interest in two recent approaches: kernel and spectral methods ...

On spaces of fuzzy metrics [PDF]
Математичні Студії, 2012 We consider the space of all fuzzy metrics in the sense of George and Veeramani that are compatible with the topology of a compact metrizable space. It is proved that this space of fuzzy metrics is an l^2-manifold.

A Dimension Reduction Framework for HSI Classification Using Fuzzy and Kernel NFLE Transformation
Remote Sensing, 2015 In this paper, a general nearest feature line (NFL) embedding (NFLE) transformation called fuzzy-kernel NFLE (FKNFLE) is proposed for hyperspectral image (HSI) classification in which kernelization and fuzzification are simultaneously considered.

Fuzzy Atomic System and Fuzzy K-frame in Fuzzy Hilbert Space
New Mathematics and Natural ComputationAtomic system in fuzzy Hilbert space is introduced and the existence of the fuzzy atomic systems for a strongly fuzzy bounded linear operator is studied. The notion of a K-frame in fuzzy Hilbert space is presented and some of their characterizations are given.

Some results on Fuzzy Pre- Hilbert Space
Journal of the College of Basic Education, 2023 الهدف من هذا العمل هو تقديم تعريف جديد لمساحة ما قبل هلبرت الضبابية (مساحة المنتج الداخلية الضبابية) وناقش العلاقة بين مساحة ما قبل هلبرت الضبابية وفضاء ما قبل هلبرت العادي.يتم إيلاء الكثير من الاهتمام لمفاهيم تقارب التسلسل (على سبيل المثال تسلسل كوشي للنقطة الضبابية) ومفهوم ارتباط هذه التسلسلات.

New Directions in Categorical Logic, for Classical, Probabilistic and Quantum Logic [PDF]
Logical Methods in Computer Science, 2015 Intuitionistic logic, in which the double negation law not-not-P = P fails, is dominant in categorical logic, notably in topos theory. This paper follows a different direction in which double negation does hold.

Advanced Science, EarlyView.Stem cell differentiation follows a conserved surface condensate trajectory: H3K27ac super enhancers nucleate large RNA polymerase II clusters that grow and unfold before transcriptional activity disperses them. This work reveals how biophysical forces at enhancer surfaces dynamically build and dismantle stem cell transcription hubs, reshaping cell ...
