Tensor Ring Decomposition for High-Dimensional Data Analysis

Blog Article

Tensor ring decomposition offers a powerful framework for analyzing high-dimensional data. This technique factorizes a multi-way array, also known as a tensor, into a sum of smaller tensors with specific structural properties. By exploiting the low-rank structure of tensors, tensor ring decomposition diminishes the dimensionality of the data while preserving its essential content. This process promotes efficient storage, computation, and visualization of large-scale datasets.

• Tensor ring decomposition has revealed applications in a wide range of domains, including computer vision, natural language processing, and recommendation systems.
• Additionally, its ability to capture sophisticated interactions among multiple dimensions makes it particularly appropriate for analyzing high-order correlations in data.

The effectiveness of tensor ring decomposition stems from its power to model intricate relationships within tensors. By decomposing a tensor into smaller components, it uncovers latent structures and patterns that may not be readily visible through traditional dimensionality reduction techniques.

Efficient Tensor Ring Factorization via Stochastic Gradient Descent

Tensor ring representation (TRF) has emerged as a powerful technique for efficient computational analysis of high-dimensional tensors. However, traditional TRF methods can be computationally expensive, particularly for large tensors.

To address this challenge, we propose an novel approach based on stochastic gradient descent (SGD) for optimizing the parameters of the tensor ring representation. Our algorithm leverages the inherent sparse nature of tensors to substantially reduce the computational complexity. Furthermore, we evaluate the performance of our method on a variety of benchmark datasets, demonstrating its efficiency compared to state-of-the-art TRF algorithms.

Learning Tensor Rings with Adaptive Kronecker Structures

Tensor factorization has emerged as a powerful tool for representing high-dimensional data in a compact and efficient manner. Kronecker decompositions provide a particular type of tensor factorization that exploits the inherent multilinearity of tensors, leading to significant efficiency benefits. However, traditional Kronecker structures often impose rigid assumptions here on the underlying tensor geometry, which may not always be suitable for complex real-world data. To address this limitation, we propose a novel approach called Adaptive Kronecker Tensor Rings (AKTR), which learns adaptive Kronecker structures that represent the inherent multilinear structures within the tensor data.

AKTR employs a differentiable optimization framework to iteratively refine the Kronecker structure parameters, driven by the underlying tensor data distribution. This allows for the discovery of complex tensor structures that accurately represent the data, even in cases where traditional Kronecker structures fall short. Extensive experiments on a variety of benchmark datasets demonstrate the effectiveness of AKTR over existing tensor decomposition methods, showcasing its ability to achieve higher performance in terms of both accuracy and computational efficiency.
