  "Description": "Solves Hidden Markov Models (HMMs) via matrix and tensor\ndecomposition. Converts observation sequences to co-occurrence\nmatrices/tensors and applies Symmetric Non-negative Matrix\nFactorization (symNMF), Singular Value Decomposition (SVD),\nCANDECOMP/PARAFAC (CP) decomposition, or Tensor-Train (TT)\ndecomposition to recover HMM parameters. Also provides standard\nHMM algorithms (Forward, Backward, Viterbi, Baum-Welch) for\ncomparison. The spectral learning approach for HMMs is based on\nHsu, Kakade, and Zhang (2012) <doi:10.1016/j.jcss.2011.12.025>.\nThe symNMF method is described in Kuang, Yun, and Park (2015)\n<doi:10.1007/s10898-014-0247-2>. The Tensor-Train decomposition\nis described in Oseledets (2011) <doi:10.1137/090752286>.",
