Hi Gaurav,
thanks for your interest in uBLAS. You can find the documentation, examples
and implementation of the tensor data type on Github
<https://github.com/BoostGSoC18/tensor/wiki/Documentation#general>.
Project 2 and 3 for the tensor extension on the Boost GSoC page are not
defined yet.
A good starting point for implementing tensor algorithms are e.g. Tensor
Decomposition
<http://www.maths.manchester.ac.uk/~mlotz/teaching/nur/tensordecompositions.pdf>
or Fundamental Operations <https://arxiv.org/abs/1405.7786>. The current
data type supports conventional tensor contractions. However, we still
might need some special products such as the hadamard or kronecker product
in order to perform alternative least square algorithms, higher-order
singular value decomposition or higher-order power methods for e.g.
large-scale data analysis and quantum computing applications.
Best
Cem
