Anton Dmitriev updated IGNITE-7438:
-----------------------------------
Description:
This task consists of two parts:
* Implementation of the +LSQR iterative solver+ of systems of linear equations.
* Implementation of the +LSQR-based linear regression trainer+.
Apache Ignite LSQR iterative solver is based on [SciPy reference
implementation|http://example.com/], but it's distributed and can:
* Efficiently work in cases when a data is distributed across a cluster.
* Utilizes all CPU resources by processing different parts of data on
different cores.
Distribution is achieved as result of changing [Golub-Kahan-Lanczos
Bidiagonalization
Procedure|http://www.netlib.org/utk/people/JackDongarra/etemplates/node198.html]
procedure which is a core of LSQR algorithm and utilizing features of
Partition based dataset implementation.
