HST observations of the LMC field around SN87A: distance determinations with Red Clump and Tip of the Red Giant Branch stars [PDF]
, 1999 We have used HST-WFPC2 multiband observations of a field around SN 1987A in the Large Magellanic Cloud to measure its distance from the Sun. The observations allowed us to carefully determine the interstellar extinction along the line of sight to a large

A Robust Distance Measure for Similarity-Based Classification on the SPD Manifold
IEEE Transactions on Neural Networks and Learning Systems, 2020 The symmetric positive definite (SPD) matrices, forming a Riemannian manifold, are commonly used as visual representations. The non-Euclidean geometry of the manifold often makes developing learning algorithms (e.g., classifiers) difficult and ...

Effects of Distance Measure Choice on K-Nearest Neighbor Classifier Performance: A Review [PDF]
Big Data, 2017 The K-nearest neighbor (KNN) classifier is one of the simplest and most common classifiers, yet its performance competes with the most complex classifiers in the literature.

SCM Enables Improved Single-Cell Clustering by Scoring Consensus Matrices
Mathematics, 2023 Single-cell clustering facilitates the identification of different cell types, especially the identification of rare cells. Preprocessing and dimensionality reduction are the two most commonly used data-processing methods and are very important for ...

Trace-distance measure of coherence
, 2016 We show that trace distance measure of coherence is a strong monotone for all qubit and, so called, $X$ states. An expression for the trace distance coherence for all pure states and a semi definite program for arbitrary states is provided.

Generalized Wasserstein distance and its application to transport equations with source [PDF]
, 2012 In this article, we generalize the Wasserstein distance to measures with different masses. We study the properties of such distance. In particular, we show that it metrizes weak convergence for tight sequences.

Operationally Invariant Measure of the Distance between Quantum States by Complementary Measurements
, 2003 We propose an operational measure of distance of two quantum states, which conversely tells us their closeness. This is defined as a sum of differences in partial knowledge over a complete set of mutually complementary measurements for the two states. It

Characteristic Analysis of Judgment Debtors Based on Hesitant Fuzzy Linguistic Clustering Method
IEEE Access, 2021 In most law enforcement cases, judgment debtors have behaviors of evading execution in China, which seriously affects the authority of legal judgments and the judiciary’s credibility. Characteristics analysis of judgment debtors plays a vital role
