Scenario Discovery Using Nonnegative Tensor Factorization [PDF]

open access: yes, 2008
In the relatively new field of visual analytics there is a great need for automated approaches to both verify and discover the intentions and schemes of primary actors through time. Data mining and knowledge discovery play critical roles in facilitating the ability to extract meaningful information from large and complex textual-based (digital ...

Modeling Hierarchical Seasonality Through Low-Rank Tensor Decompositions in Time Series Analysis

open access: yesIEEE Access, 2023
Accurately representing periodic behavior is a frequently encountered challenge in modeling time series. This is especially true for observations where multiple, nested seasonalities are present, which is often encountered in data that pertain to ...

Discriminative Nonnegative Tucker Decomposition for Tensor Data Representation

open access: yesMathematics, 2022
Nonnegative Tucker decomposition (NTD) is an unsupervised method and has been extended in many applied fields. However, NTD does not make use of the label information of sample data, even though such label information is available.

Model Selection for Non-Negative Tensor Factorization with Minimum Description Length

open access: yesEntropy, 2019
Non-negative tensor factorization (NTF) is a widely used multi-way analysis approach that factorizes a high-order non-negative data tensor into several non-negative factor matrices.

SWIFT: Scalable Wasserstein Factorization for Sparse Nonnegative Tensors

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2021
Existing tensor factorization methods assume that the input tensor follows some specific distribution (i.e. Poisson, Bernoulli, and Gaussian), and solve the factorization by minimizing some empirical loss functions defined based on the corresponding distribution.
