  • Computation of Compact Distributions of Discrete Elements
    Article Computation of Compact Distributions of Discrete Elements Jie Chen, Gang Yang *, Meng Yang School of Information Science & Technology, Beijing Forestry University, Beijing, 100083, China; [email protected] (J.C.); [email protected] (M.Y.) * Correspondence: [email protected]; Tel.: +86-10-62338915 Received: 29 December 2018; Accepted: 13 February 2019; Published: 18 February 2019 Abstract: In our daily lives, many plane patterns can actually be regarded as a compact distribution of a number of elements with certain shapes, like the classic pattern mosaic. In order to synthesize this kind of pattern, the basic problem is, with given graphics elements with certain shapes, to distribute a large number of these elements within a plane region in a possibly random and compact way. It is not easy to achieve this because it not only involves complicated adjacency calculations, but also is closely related to the shape of the elements. This paper attempts to propose an approach that can effectively and quickly synthesize compact distributions of elements of a variety of shapes. The primary idea is that with the seed points and distribution region given as premise, the generation of the Centroidal Voronoi Tesselation (CVT) of this region by iterative relaxation and the CVT will partition the distribution area into small regions of Voronoi, with each region representing the space of an element, to achieve a compact distribution of all the elements. In the generation process of Voronoi diagram, we adopt various distance metrics to control the shape of the generated Voronoi regions, and finally achieve the compact element distributions of different shapes.

  • CS245 Distance Metric
    CS245 Distance Metric Yifan Lu, Yueyang Wu, Yuxin Lin April 2021 Abstract In this report, we do classification task on AwA2 dataset using K-Nearest-Neighbor algorithm. Based on the KNN method, we explored different metrics to measure the distance between samples, including various Minkowski distance, Cosine distance, etc. Also, we tried different metric learning method to do the task, including LMNN, LFDA, LSML, Covariance. Under each method, we do experiment on different parameters to attain the best performance. 1 Introduction Distance metric is a key issue in many machine learning algorithms. Algorithms such as K Nearest Neighbor rely on the distance metric for the input data pattern heavily. Thus, how to measure the distance between samples and between distributions has received lots of attention. In this report we will talk about a number of techniques that is central to distance metric, including formula based distance and metric-learning based distance. Metric learning is to learn a distance metric for the input space of data from a given collection of pair of similar/dissimilar points that preserves the distance relation among the training data. Many studies have shown that a learned metric can significantly improve the performance of many ML tasks, like clustering, classification, retrieval and so on. Depending on the availability ofthe training examples, algorithms for distance metric learning can be divided into two categories: supervised distance metric learning and unsupervised distance metric learning. 2 Dataset Preparation AwA2[2] dataset consists of 37322 images of 50 animals classes. The author uses ResNet-101 to extract 2048-d deep learning feature to help training.

The examination will be conducted in English. Faculty examiner: Hugues Talbot (University Paris-Est - ESIEE). Abstract Ćurić, V. 2014. Distance Functions and Their Use in Adaptive Mathematical Morphology. Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 1137. 88 pp. Uppsala: Acta Universitatis Upsaliensis. ISBN 978-91-554-8923-6. One of the main problems in image analysis is a comparison of different shapes in images. It is often desirable to determine the extent to which one shape differs from another. This is usually a difficult task because shapes vary in size, length, contrast, texture, orientation, etc. Shapes can be described using sets of points, crisp of fuzzy. Hence, distance functions between sets have been used for comparing different shapes. Mathematical morphology is a non-linear theory related to the shape or morphology of features in the image, and morphological operators are defined by the interaction between an image and a small set called a structuring element. Although morphological operators have been extensively used to differentiate shapes by their size, it is not an easy task to differentiate shapes with respect to other features such as contrast or orientation.

  • PTOLEMAIC INDEXING 1 Introduction
    Journal of Computational Geometry jocg.org PTOLEMAIC INDEXING Magnus Lie Hetland ∗ Abstract. This paper discusses a new family of bounds for use in similarity search, related to those used in metric indexing, but based on Ptolemy's inequality, rather than the metric axioms. Ptolemy's inequality holds for the well-known Euclidean distance, but is also shown here to hold for quadratic form metrics in general, with Mahalanobis distance as an important special case. The inequality is examined empirically on both synthetic and real-world data sets and is also found to hold approximately, with a very low degree of error, for important distances such as the angular pseudometric and several Lp norms. Indexing experiments demonstrate a highly increased filtering power compared to existing, triangular methods. It is also shown that combining the Ptolemaic and triangular filtering can lead to better results than using either approach on its own. 1 Introduction In similarity search, data objects are retrieved based on their similarity to a query object; as for other modes of information retrieval, the related indexing methods seek to improve the efficiency the search. Two approaches seem to dominate the field: spatial access meth- ods [1{3], based on coordinate geometry, and metric access methods [4{7], based on the metric axioms. Similarity retrieval with spatial access methods is often restricted to Lp k norms, or other norms with predictable behavior in R , while metric access methods are designed to work with a broader class of distances|basically any distance that satisfies the triangular inequality. This gives the metric approach a wider field of application, by for- going some assumptions about the data, which in some cases results in lower performance.

  • What Is Distance in Science
    1 What Is Distance In Science The Hausdorff distance is the larger of two values, one being the supremum, for a point ranging over one set, of the infimum, for a second point ranging over the other set, of the distance between the points, and the other value being likewise defined but with the roles of the two sets swapped. for the Earth Moon distance, the latter. The infinity norm distance is also called Chebyshev distance. p need not be an integer, but it cannot be less than 1, because otherwise the triangle inequality does not hold. The distance traveled by a particle must always be greater than or equal to its displacement, with equality occurring only when the particle moves along a straight path. Both distance and displacement measure the movement of an object. a weighted version of Manhattan distance, used in computer science. But distance on a given set is a definitional choice. -y_ , x_ -y_ , ldots , x_ -y_ right. In physical space the Euclidean distance is in a way the most natural one, because in this case the length of a rigid body does not change with rotation. You may need to download version 2. Since the new objects that are dealt with are extended objects not points any- more additional concepts such as non-extensibility, curvature constraints, and non-local interactions that enforce non-crossing become central to the notion of distance. This corresponds to the distance, according to the first-mentioned definition above of the distance between sets, from the set containing only this point to the other set.

  • A Generalization of the Minkowski Distance and New Definitions of the Central Conics
    Turkish Journal of Mathematics Turk J Math (2020) 44: 319 – 333 http://journals.tubitak.gov.tr/math/ © TÜBİTAK Research Article doi:10.3906/mat-1904-56 A generalization of the Minkowski distance and new definitions of the central conics Harun Barış ÇOLAKOĞLU∗ Department of Computer Technologies, Vocational School of Technical Sciences, Akdeniz University, Antalya, Turkey Received: 08.04.2019 • Accepted/Published Online: 06.01.2019 • Final Version: 20.01.2020 Abstract: In this paper, we give a generalization of the well-known Minkowski distance family in the n-dimensional Cartesian coordinate space. Then we consider three special cases of this family, which are also generalizations of the taxicab, Euclidean, and maximum metrics, respectively, and we determine some circle properties of them in the real plane. While we determine some properties of circles of these generalized distances, we discover a new definition of ellipses, and then we also determine a similar definition of hyperbolas, which will be new members among different metrical definitions of central conics in the Euclidean plane. Key words: Minkowski distance, lp -norm, lp -metric, taxicab distance, Manhattan distance, Euclidean distance, maximum distance, Chebyshev distance, ellipse, hyperbola, central conics, asymptote, eccentrix, eccentricity 1. Introduction Beyond mathematics, distances, especially the well-known Minkowski distance (also known as lp -metric) with its special cases of taxicab (also known as l1 or Manhattan), Euclidean (also known as l2 ), and maximum (also known as l1 or Chebyshev) distances, are very important keys for many application areas such as data mining, machine learning, pattern recognition, and spatial analysis. Here, we give a generalization of the Minkowski distance in the n-dimensional Cartesian coordinate space, which gives a new metric family for p ≥ 1, and we consider this generalization for special cases p = 1, p = 2, and p ! 1, which we call the generalized taxicab, Euclidean, and maximum metrics, respectively.

  • 曼哈顿距离、欧几里得距 离与契比雪夫距离 ——葛振兴 曼哈顿距离(Taxicab Geometry)
    曼哈顿距离、欧几里得距 离与契比雪夫距离 ——葛振兴 曼哈顿距离(TAXICAB GEOMETRY) • Taxicab geometry, considered by Hermann Minkowski in 19th-century Germany, is a form of geometry in which the usual distance function of metric or Euclidean geometry is replaced by a new metric in which the distance between two points is the sum of the absolute differences of their Cartesian coordinates. FORMAL DEFINITION APPLICATION • 1、Compressed sensing • 2、Differences of frequency distributions Next COMPRESSED SENSING • Compressed sensing (also known as compressive sensing, compressive sampling, or sparse sampling) is a signal processing technique for efficiently acquiring and reconstructing a signal, by finding solutions to underdetermined linear systems. • Shannon-Nyquist sampling theorem Back FREQUENCY DISTRIBUTIONS • For example, in RNA splicing positional distributions of hexamers, which plot the probability of each hexamer appearing at each given nucleotide near a splice site, can be compared with L1-distance. Each position distribution can be represented as a vector where each entry represents the likelihood of the hexamer starting at a certain nucleotide. A large L1-distance between the two vectors indicates a significant difference in the nature of the distributions while a small distance denotes similarly shaped distributions. This is equivalent to measuring the area between the two distribution curves because the area of each segment is the absolute difference between the two curves' likelihoods at that point. When summed together for all segments, it provides the same measure as L1-distance. EUCLIDEAN DISTANCE • In mathematics, the Euclidean distance or Euclidean metric is the "ordinary" (i.e. straight-line) distance between two points in Euclidean space. With this distance, Euclidean space becomes a metric space.

  • Distances in Classification Café Scientifique - 07/01/2016 Introduction
    DISTANCES IN CLASSIFICATION CAFÉ SCIENTIFIQUE - 07/01/2016 INTRODUCTION The notion of distance is the most important basis for classification. Standard distances often do not lead to appropriate results. For every individual problem the adequate distance is to be decided upon. The right choice of the distance measure is one of the most decisive steps for the determination of cluster properties. EUCLIDEAN DISTANCE The Euclidean distance or Euclidean metric is the "ordinary" (i.e. straight-line) distance between two points in Euclidean space. The Euclidean distance between points p and q is the length of the line segment connecting them ( ). MANHATTAN DISTANCE Taxicab geometry is a form of geometry in which the usual metric of Euclidean geometry is replaced by a new metric in which the distance between two points is the sum of the (absolute) differences of their coordinates. The Manhattan distance, also known as rectilinear distance, city block distance, taxicab metric is defined as the sum of the lengths of the projections of the line segment between the points onto the coordinate axes. In chess, the distance between squares on the chessboard for rooks is measured in Manhattan distance. EUCLIDEAN VS. MANHATTAN DISTANCE CHEBYSHEV DISTANCE The Chebyshev distance between two vectors or points p and q, with standard coordinates and respectively, is : It is also known as chessboard distance, since in the game of chess the minimum number of moves needed by a king to go from one square on a chessboard to another equals the Chebyshev distance between the centers of the squares HAMMING DISTANCE The Hamming distance between two strings of equal length is the number of positions at which the corresponding symbols are different.
