tapkee-devel Subpackage of tapkee

Tapkee is a C++ template library for dimensionality reduction with some bias on spectral methods. The Tapkee origins from the code developed during GSoC 2011 as the part of the Shogun machine learning toolbox. The project aim is to provide efficient and flexible standalone library for dimensionality reduction which can be easily integrated to existing codebases. Tapkee leverages capabilities of effective Eigen3 linear algebra library and optionally makes use of the ARPACK eigensolver. The library uses CoverTree and VP-tree data-structures to compute nearest neighbors. To achieve greater flexibility we provide a callback interface which decouples dimension reduction algorithms from the data representation and storage schemes. Tapkee provides implementations of the following dimension reduction methods: * Locally Linear Embedding and Kernel Locally Linear Embedding (LLE/KLLE) * Neighborhood Preserving Embedding (NPE) * Local Tangent Space Alignment (LTSA) * Linear Local Tangent Space Alignment (LLTSA) * Hessian Locally Linear Embedding (HLLE) * Laplacian eigenmaps * Locality Preserving Projections * Diffusion map * Isomap and landmark Isomap * Multidimensional scaling and landmark Multidimensional scaling (MDS/lMDS) * Stochastic Proximity Embedding (SPE) * PCA and randomized PCA * Kernel PCA (kPCA) * Random projection * Factor analysis * t-SNE * Barnes-Hut-SNE
