Decoherence effects on quantum Fisher information of multi-qubit W states

Quantum fisher information of a parameter characterizing the sensitivity of a state with respect to parameter changes. In this paper, we study the quantum fisher information of the W state for four, five, six and seven particles in decoherence channels, such as amplitude damping, phase damping and depolarizing channel. Using Krauss operators for decoherence channels components, we investigate t...

Iterative K-Means Algorithm Based on Fisher Discriminant

K-Means clustering is a well-known tool in unsupervised learning. The performance of K-Means clustering, measured by the F-ratio validity index, highly depends on selection of its initial partition. This problematic dependency always leads to a local optimal solution for k-center clustering. To overcome this difficulty, we present an intuitive approach that iteratively incorporates Fisher discr...
