Overview

BIGtensor is a large-scale tensor mining package. Users can select one of platforms, which are single machine or distributed Hadoop platform, to run the BIGtensor. BIGtensor is designed to fully utilize CPU and GPU in the single machine platform. BiGtensor also runs on a distributed Hadoop platform, an open-source version of MapReduce framework.

BIGtensor provides various tensor operations:

  • Tensor operations: matricization, n-mode product, scalar operations, etc.
  • Tensor generations: generation where all tensor values are set to 1, random tensor generation, tensor generation from factor matrices and core tensor
  • Tensor decompositions: PARAFAC, Nonnegative PARAFAC, Tucker, Nonnegative Tucker, Coupled Matrix-tensor Factorization (Tucker),
