Clifford Kolmogorov-Arnold Networks
Authors: Matthias Wolff, Francesco Alesiani, Christof Duhme, Xiaoyi Jiang
This research introduces the Clifford Kolmogorov-Arnold Network (CIKAN), an innovative architecture extending KANs to hypercomplex spaces. It tackles the challenge of exponential scaling in high-dimensional AI applications by leveraging Clifford algebras, Randomized Quasi Monte Carlo (RQMC) Sobol grids, and novel batch normalization techniques. CIKAN offers a flexible and efficient solution for function approximation in complex scientific and engineering domains.
The Challenge: Scaling AI for High-Dimensional Data
Traditional Kolmogorov-Arnold Networks (KANs) and their complex-valued extensions (CVKANs) primarily operate on real or complex numbers, limiting their applicability in domains requiring higher-dimensional representations. Scientific discovery, engineering, computer vision, and robotics often involve data where complex numbers are insufficient, leading to an exponential increase in computational complexity and parameters, known as the "curse of dimensionality."
Our AI Solution: Clifford Kolmogorov-Arnold Networks (CIKAN)
CIKAN extends the CVKAN framework to arbitrary Clifford algebra spaces, enabling function approximation in hypercomplex domains. It employs the geometric product of Clifford algebras and introduces two types of Radial Basis Functions (RBFs). Crucially, CIKAN utilizes a Randomized Quasi Monte Carlo (RQMC) Sobol grid for RBF generation, drastically mitigating the curse of dimensionality by reducing the number of trainable parameters while ensuring efficient space coverage. Furthermore, novel batch normalization strategies are integrated to handle variable domain inputs effectively.
Key Enterprise Impact: Enhanced Scalability & Efficiency
CIKAN empowers enterprises to develop AI solutions for previously intractable high-dimensional problems in fields like electromagnetism, 3D object modeling, and advanced robotics. By significantly reducing the number of parameters needed for accurate function approximation (up to 75% parameter reduction for similar performance), CIKAN drives substantial cost efficiencies and accelerates development cycles. Its interpretability and flexibility make it a powerful tool for scientific discovery and advanced engineering applications.

The Power of Clifford Algebras in AI
Clifford (Geometric) Algebras (CA) provide a robust mathematical framework for describing spatial relationships and transformations, extending beyond complex numbers and quaternions. They are crucial for representing high-dimensional data, such as electromagnetic fields or 3D objects, enabling AI models to process richer, more structured information. CIKAN leverages CA to perform function approximation in these complex, multi-dimensional spaces.
Enterprise Application: CA-powered AI systems can more accurately model and predict complex physical phenomena, leading to breakthroughs in materials science, fluid dynamics, and advanced sensor fusion for autonomous systems. For example, Cl(2) for weather modeling, Cl(3) for Maxwell's equations, and Conformal Geometric Algebra (Cl(4,1)) for robotics.
CIKAN: A Novel Function Approximation Architecture
The Clifford Kolmogorov-Arnold Network (CIKAN) extends the KAN framework by incorporating Clifford algebras. Each edge in a CIKAN can learn a function mapping from a Clifford element to another Clifford element. This is achieved by combining multiple Radial Basis Functions (RBFs) centered on grid points within the Clifford algebra space. Two types of RBFs are introduced: a "naive" real-valued RBF and a "Clifford" RBF that preserves the spatial properties of the input.
Enterprise Application: CIKAN offers a flexible and intrinsically interpretable architecture for complex function fitting, outperforming traditional MLPs in certain scenarios. Its ability to work with arbitrary Clifford algebras makes it suitable for advanced simulations, control systems, and data analysis where geometric properties are paramount.
Mitigating the Curse of Dimensionality with Sobol Grids
A major challenge in extending KANs to higher dimensions is the exponential increase in grid points required for RBFs, leading to an explosion in trainable parameters – the "curse of dimensionality." CIKAN addresses this by replacing uniform grids with Randomized Quasi Monte Carlo (RQMC) Sobol sequences. These Sobol grids provide a more even and efficient coverage of the high-dimensional space with significantly fewer points, reducing the number of trainable parameters by up to 75% while maintaining comparable performance.
Enterprise Application: This innovation drastically reduces the computational cost and memory footprint of high-dimensional AI models. Enterprises can deploy more complex models with fewer resources, accelerate training times, and tackle larger, more intricate datasets in fields like bioinformatics, financial modeling, and quantum computing.
Optimized Batch Normalization for Hypercomplex Data
CIKAN introduces three new batch normalization strategies tailored for high-dimensional Clifford algebras: dimension-wise, node-wise, and component-wise. These methods ensure that inputs to subsequent layers remain within optimal ranges, preventing issues where RBF outputs become zero due to out-of-range data. This is crucial for maintaining model stability and performance, especially with variable domain inputs.
Enterprise Application: Robust batch normalization improves the stability and generalization capabilities of CIKAN across diverse datasets and training conditions. This translates to more reliable AI systems, reduced need for hyperparameter tuning, and faster convergence during model development in complex industrial applications.

Critical Efficiency Gain
0% Reduction in Parameters for Equivalent Performance (Sobol Grid, Ng=7)CIKAN's use of a Randomized Quasi Monte Carlo Sobol grid significantly reduces the computational overhead, making high-dimensional AI more viable for enterprise applications.
Case Study: Higher-Dimensional Clifford Algebras
CIKAN was evaluated on various higher-dimensional Clifford Algebras, including Euclidean GA (Cl(2)), quaternions (Cl(0,2)), zero-dimensional Conformal GA (Cl(1,1)), and one-dimensional Projective Geometric Algebra (Cl(1,0,1)). For datasets like mult (6c) and square (6a), CIKAN successfully learned the functions with low MSE, demonstrating its versatility.
Crucially, the Sobol grid approach proved highly beneficial, especially for Cl(1,0,1), where it achieved even better performance with Ng=4 compared to a full grid, using a drastically reduced number of parameters (e.g., ~2-6% of parameters for similar results). This confirms CIKAN's ability to tackle complex, high-dimensional problems efficiently, opening doors for advanced modeling in physics, engineering, and computer graphics.
