Tropical Geometry and Machine Learning [PDF]

open access: yesProceedings of the IEEE, 2021
Tropical geometry is a relatively recent field in mathematics and computer science, combining elements of algebraic geometry and polyhedral geometry. The scalar arithmetic of its analytic part preexisted in the form of max-plus and min-plus semiring arithmetic used in finite automata, nonlinear image processing, convex analysis, nonlinear control ...

Geometry in the tropical limit [PDF]

open access: yesMathematische Semesterberichte, 2011
Complex algebraic varieties become easy piecewise-linear objects after passing to the so-called tropical limit. Geometry of these limiting objects is known as tropical geometry. In this short survey we take a look at motivation and intuition behind this limit and consider a few simple examples of correspondence principle between classical and tropical ...

Tropical geometry of statistical models. [PDF]

open access: yesProc Natl Acad Sci U S A, 2004
This article presents a unified mathematical framework for inference in graphical models, building on the observation that graphical models are algebraic varieties. From this geometric viewpoint, observations generated from a model are coordinates of a point in the variety, and the sum-product algorithm is an efficient tool for evaluating specific ...

Product-Mix Auctions and Tropical Geometry [PDF]

open access: yesMathematics of Operations Research, 2019
In a recent and ongoing work, Baldwin and Klemperer explore a connection between tropical geometry and economics. They give a sufficient condition for the existence of competitive equilibrium in product-mix auctions of indivisible goods. This result, which we call the unimodularity theorem, can also be traced back to the work of Danilov, Koshevoy, and

Tropical geometry of Rado matroids [PDF]

open access: yesDiscrete Mathematics Letters
In this note, we characterize the products of simplicial generators for the Chow ring of a loopless matroid, extending a result of Backman, Eur, and Simpson. We prove that the stable intersection of a collection of tropical hyperplanes centered at the origin with the Bergman fan of a matroid is the Bergman fan of the dual of a certain Rado matroid.

Tropical Algebraic Geometry

open access: yesHokkaido Mathematical Journal, 2009
The construction of a tropical hypersurface is given by modeling the classical construction of a complex hypersurface. A tropical meromorphic function of finite type is shown to be a tropical rational function. One also has tropical nullstellensatz.

Imputing Phylogenetic Trees Using Tropical Polytopes over the Space of Phylogenetic Trees

open access: yesMathematics, 2023
When we apply comparative phylogenetic analyses to genome data, it poses a significant problem and challenge that some of the given species (or taxa) often have missing genes (i.e., data).

Clustering Methods over the Tropical Projective Torus

open access: yesMathematics, 2023
In this paper, we propose clustering methods for use on data described as tropically convex. Our approach is similar to clustering methods used in the Euclidean space, where we identify groupings of similar observations using tropical analogs of K-means ...
