Portfolio Evaluation with the Vector Distance Based on Portfolio Composition
Mathematics, 2023 We propose a novel portfolio evaluation method, a distance-based approach, which directly evaluates the portfolio composition rather than portfolio returns.

Euclidean distance mapping [PDF]
Computer Graphics and Image Processing, 1980 Abstract Based on a two-component descriptor, a distance label for each point, it is shown that Euclidean distance maps can be generated by effective sequential algorithms. The map indicates, for each pixel in the objects (or the background) of the originally binary picture, the shortest distance to the nearest pixel in the background (or the objects)

Euclidean Distance Degree and Mixed Volume [PDF]
Foundations of Computational Mathematics, 2021 AbstractWe initiate a study of the Euclidean distance degree in the context of sparse polynomials. Specifically, we consider a hypersurface $$f=0$$ f = 0 defined by a polynomial f that is general given its support, such that the support ...

On Directed Length Ratios in the Lorentz-Minkowski Plane
Cumhuriyet Science Journal, 2023 The linear structure of the Lorentz-Minkowski plane is almost the same as Euclidean plane. But, there is one different aspect. These planes have different distance functions. So, it can be interesting to study the Lorentz analogues of topics that include

Road distance and travel time for an improved house price Kriging predictor
Geo-spatial Information Science, 2018 The paper designs an automated valuation model to predict the price of residential property in Coventry, United Kingdom, and achieves this by means of geostatistical Kriging, a popularly employed distance-based learning method.

Comparison of distance measures in spatial analytical modeling for health service planning
BMC Health Services Research, 2009 Background Several methodological approaches have been used to estimate distance in health service research. In this study, focusing on cardiac catheterization services, Euclidean, Manhattan, and the less widely known Minkowski distance metrics are used ...

Selective Image Segmentation Models Using Three Distance Functions
Journal of ICT, 2021 Image segmentation can be defined as partitioning an image that contains multiple segments of meaningful parts for further processing. Global segmentation is concerned with segmenting the whole object of an observed image.

Dimensional contraction via Markov transportation distance [PDF]
, 2013 It is now well known that curvature conditions \`a la Bakry-Emery are equivalent to contraction properties of the heat semigroup with respect to the classical quadratic Wasserstein distance.
