Machine learning has expanded beyond traditional Euclidean spaces in recent years, exploring representations in more complex geometric structures. Non-Euclidean representation learning is a growing field that seeks to capture the underlying geometric properties of data by embedding it in hyperbolic, spherical, or mixed-curvature product spaces. These approaches have been particularly useful in modeling hierarchical, structured, or networked data more efficiently than Euclidean embeddings. The field has witnessed significant advancements with new tools and algorithms to facilitate these complex representations.A significant challenge in this domain is the lack of a unified framework integrating different approaches to non-Euclidean representation learning. Current methodologies are often dispersed across multiple software packages, creating inefficiencies in implementation. Many existing tools cater to specific types of non-Euclidean spaces, restricting their broader applicability. Researchers require a comprehensive and accessible library that enables seamless embedding, classification, and regression while maintaining compatibility with established machine learning frameworks. Addressing this gap is crucial for advancing non-Euclidean machine learning research and applications.Several tools have been introduced to facilitate manifold-based machine learning. Geoopt, a Python package, provides Riemannian optimization for non-Euclidean manifolds, but its functionality is limited. Other implementations focus on hyperbolic learning but lack consistency, resulting in fragmented methodologies. The absence of a unified, open-source toolset that bridges these gaps has made non-Euclidean machine learning less accessible to a broader research community. A more comprehensive framework is needed to enable smooth adoption and integration of non-Euclidean learning methods.A research team from Columbia University introduced Manify, an open-source Python library designed to address the limitations of existing non-Euclidean representation learning tools. Manify extends beyond current methodologies by incorporating mixed-curvature embeddings and manifold-based learning techniques into a single package. It is built upon Geoopt, enhancing its capabilities by allowing the learning of representations in products of hyperbolic, hyperspherical, and Euclidean component manifolds. The library facilitates classification and regression tasks while enabling the estimation of manifold curvature. By consolidating multiple non-Euclidean learning techniques into a structured framework, Manify provides a robust solution for researchers working with data that naturally exists in non-Euclidean spaces.Manify comprises three primary functionalities: embedding graphs or distance matrices into product manifolds, training predictors for manifold-valued data, and estimating dataset curvature. The library integrates multiple embedding methods, including coordinate learning, Siamese neural networks, and variational autoencoders, offering distinct advantages in different applications. Further, it supports various classifiers, such as decision trees, perceptrons, and support vector machines, which have been adapted to work with non-Euclidean data. Manify also features specialized tools for measuring curvature, assisting users in determining the most suitable manifold geometry for their datasets. These capabilities make it a versatile and powerful library for researchers exploring non-Euclidean learning techniques.The performance of Manify has been evaluated across multiple machine learning tasks, demonstrating significant improvements in embedding quality and predictive accuracy. The librarys ability to model heterogeneous curvature within a single framework has reduced metric distortion compared to Euclidean methods. Results indicate that embeddings generated using Manify exhibit superior structural fidelity, preserving distances more accurately than traditional techniques. The library has also demonstrated computational efficiency, with training times comparable to existing Euclidean-based methods despite the increased complexity of non-Euclidean representations. Performance benchmarks reveal that Manify achieves an average improvement of approximately 15% in classification accuracy over Euclidean embeddings, showcasing its effectiveness in manifold-based learning tasks.Manify represents a major advancement in non-Euclidean representation learning, addressing the limitations of existing tools and enabling more precise modeling of complex data structures. By offering an open-source, well-integrated framework, the library simplifies the adoption of manifold-based learning techniques for researchers and practitioners. The introduction of Manify has bridged the gap between theoretical advancements and practical implementation, making non-Euclidean learning methods more accessible to the broader scientific community. Future enhancements could further optimize its capabilities, solidifying its role as a key resource in machine learning research.Check outthe Paper and GitHub Page.All credit for this research goes to the researchers of this project.
