Distance Metric Learning Revisited
The success of many machine learning algorithms (e.g. the nearest neighborhood classification and k-means clustering) depends on the representation of the data as elements in a metric space. Learning an appropriate distance metric from data is usually superior to the default Euclidean distance. In this paper, we revisit the original model proposed by Xing et al. [24] and propose a general formu...
متن کاملInformation metric from a linear sigma model.
The idea that a space-time metric emerges as a Fisher-Rao "information metric" of instanton moduli space has been examined in several field theories, such as the Yang-Mills theories and nonlinear σ models. In this paper, we report that the flat Euclidean or Minkowskian metric, rather than an anti-de Sitter metric that generically emerges from instanton moduli spaces, can be obtained as the Fish...
متن کاملClassical metric Diophantine approximation revisited
The idea of using measure theoretic concepts to investigate the size of number theoretic sets, originating with E. Borel, has been used for nearly a century. It has led to the development of the theory of metrical Diophantine approximation, a branch of Number Theory which draws on a rich and broad variety of mathematics. We discuss some recent progress and open problems concerning this classica...
متن کاملSpatial verification using a true metric
Article history: Received 25 April 2011 Received in revised form 7 September 2011 Accepted 9 September 2011 Available online xxxx Verifying high-resolution forecasts is challenging because forecasts can be considered good by their end-users even when there is no pixel-to-pixel correspondence between the forecast and the verification fields. Many of the verification methods that have been propos...
متن کاملMetric Semantics for True Concurrent Real Time
This paper investigates the use of a complete metric space framework for providing denotational semantics to a real-time process algebra. The study is carried out in a non-interleaving setting and is based on a timed extension of Langerak's bundle event structures, a variant of Winskel's event structures. The distance function of the metric is based on the amount of time to which event structur...
