Manifold Warping: Manifold Alignment over Time
Proceedings of the AAAI Conference on Artificial Intelligence, 2021Knowledge transfer is computationally challenging, due in part to the curse of dimensionality, compounded by source and target domains expressed using different features (e.g., documents written in different languages). Recent work on manifold learning has shown that data collected in real-world settings often have high-dimensional ...

Proceedings of the AAAI Conference on Artificial Intelligence, 2015
Current manifold alignment methods can effectively align data sets that are drawn from a non-intersecting set of manifolds. However, as data sets become increasingly high-dimensional and complex, this assumption may not hold. This paper proposes a novel manifold alignment algorithm, low rank alignment (LRA), that uses a low rank ...

Multisensor alignment of image manifolds
2013 IEEE International Geoscience and Remote Sensing Symposium - IGARSS, 2013The access to many sources of satellite information is nowadays a reality. However, few methods allow to consider simultaneously data coming from different sensors, due to the differences in numbers of bands, spatial resolution and changes in the acquisition conditions.

Manifold Alignment via Local Tangent Space Alignment
2008 International Conference on Computer Science and Software Engineering, 2008Manifold alignment (Ham et al., 2005) is about mapping several datasets into a global space, and is of great importance in learning the shared latent structure (Shon et al., 2006), data fusion and multicue data matching (Lafon et al., 2006). In this paper, we propose an algorithm to solve this problem via local tangent space alignment (Zhang et al ...

Manifold Alignment with Multi-graph Embedding
Proceedings of the ACM Multimedia Asia, 2019In this paper, a novel manifold alignment approach via multi-graph embedding (MA-MGE) is proposed. Different from the traditional manifold alignment algorithms that use a single graph to describe the latent manifold structure of each dataset, our approach utilizes multiple graphs for modeling multiple local manifolds in multi-view data alignment ...

Aligning Coupled Manifolds for Face Hallucination
IEEE Signal Processing Letters, 2009Many learning-based super-resolution methods are based on the manifold assumption, which claims that point-pairs from the low-resolution representation manifold (LRM) and the corresponding high-resolution representation manifold (HRM) possess similar local geometry.

Manifold alignment using curvature information
2013 28th International Conference on Image and Vision Computing New Zealand (IVCNZ 2013), 2013Manifold learning (ML) is a known non-linear technique for representing high dimensional data. Despite the potential power of ML techniques, they fail in representing an unseen test data accurately. To better model the geometric structure of manifolds, Manifold Alignment (MA) techniques have been proposed recently, where the majority of these ...

THE HUFFMAN-LIKE ALIGNMENT IN MANIFOLD LEARNING
International Journal of Pattern Recognition and Artificial Intelligence, 2014In manifold learning, the neighborhood is often called a patch of the manifold, and the corresponding open set is called the local coordinate of the patch. The so-called alignment is to align the local coordinates in the d-dimensional Euclidean space to get the global coordinate of the manifold.

Spectral Analysis of Alignment in Manifold Learning
Proceedings. (ICASSP '05). IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005., 2006Local manifold learning methods produce a collection of overlapping local coordinate systems from a given set of sample points. Alignment is the process to stitch those local systems together to produce a global coordinate system and is done through the computation of the eigensubspace of a so-called alignment matrix.

Manifold alignment with Schroedinger eigenmaps
SPIE Proceedings, 2016The sun-target-sensor angle can change during aerial remote sensing. In an attempt to compensate BRDF effects in multi-angular hyperspectral images, the Semi-Supervised Manifold Alignment (SSMA) algorithm pulls data from similar classes together and pushes data from different classes apart.
