Yet, modern machine learning increasingly encounters richly structured data that is inherently nonEuclidean. This data can exhibit intricate geometric, topological and algebraic structure: from the geometry of the curvature of space-time, to topologically complex interactions between neurons in the brain, to the algebraic transformations describing symmetries of physical systems. Extracting knowledge from such non-Euclidean data necessitates a broader mathematical perspective. Echoing the 19th-century revolutions that gave rise to non-Euclidean geometry, an emerging line of research is redefining modern machine learning with non-Euclidean structures. Its goal: generalizing classical methods to unconventional data types with geometry, topology, and algebra. In this review, we provide an accessible gateway to this fast-growing field and propose a graphical taxonomy that integrates recent advances into an intuitive unified framework. We subsequently extract insights into current challenges and highlight exciting opportunities for future development in this field.  \nIndex Terms—Geometric Deep Learning, Geometry, Topology, Algebra, Machine Learning  \nI. INTRODUCTION  \nFor nearly two millennia, Euclid’s Elements of Geometry formed the backbone of our understanding of space and shape. This ‘Euclidean’ view of geometry—characterized by flat planes and straight lines—remained unquestioned until the 19th century. Only then, did mathematicians venture “beyond” to develop the principles of non-Euclidean geometry on curved spaces. Their pioneering work revealed that there is no singular, true geometry. Instead, Euclidean geometry is but one in a mathematical universe of geometries, each of which can be used to illuminate different structures in nature—from the mechanics of celestial bodies embracing the curvature of spacetime to the topologically and algebraically complex electri-  \ncal patterns of neurons in natural and artificial neural networks.  \nThis non-Euclidean revolution was part of a greater trend towards generalization and abstraction in 19th and 20th century mathematics. In addition to expanding the realm of geometry, mathematicians proceeded to define more abstract notions of space, freed from rigid geometric concepts like distances and angles. This gave rise to the field of topology, which examines the properties of a space that are preserved under continuous transformations such as stretching and bending. By abstracting away from the rigidity of geometric structures, topology emphasizes more general spatial properties such as continuity and connectedness. Indeed, two structures that look very different from a geometric perspective may be considered topologically equivalent. The famous of example of this is a donut and coffee mug, which are topologically equivalent since one can be continuously deformed into the other. This notion of abstract equivalence was supported by the simultaneous development of the field of abstract algebra, which examines the symmetries of an object—the transformations that leave its fundamental structure unchanged. These mathematical ideas quickly found applications in the natural sciences, and revolutionized how we model the world.  \nA similar revolution is now unfolding in machine learning. In the last two decades, a burgeoning body of research has expanded the horizons","cbCaipQ8hXI5lsr7","https://ap.wps.com/l/cbCaipQ8hXI5lsr7","pdf",20642751,1,36,"English","en",105,"# Introduction\n## Mathematical origins: beyond Euclid\n## Non-Euclidean revolution in machine learning\n# Core taxonomy and organization\n## Background, data structure, and model ontology\n## Software ecosystem and application domains\n# Mathematical properties\n## Topological properties\n## Geometric properties\n## Algebraic properties","[{\"question\":\"Why does modern machine learning require going beyond Euclidean geometry?\",\"answer\":\"Many real-world datasets have intrinsic structure that is not naturally Euclidean, exhibiting geometric, topological, or algebraic organization.
