AlexsLemonade / fancySVD

Only the IterativeSVD algorithm from iskandr/fancyimpute to make dependency resolution easier.

A fork of https://github.com/iskandr/fancyimpute which only includes its IterativeSVD algorithm. The original fancyimpute project had many more algorithms which required installing Tensorflow, which was difficult to do because of dependency issues. This minimal project is much simpler to install.

To install:

pip install fancySVD

Important Caveats

(1) This project is in "bare maintenance" mode. That means we are not planning on adding more imputation algorithms or features (but might if we get inspired). Please do report bugs, and we'll try to fix them. Also, we are happy to take pull requests for more algorithms and/or features.

Usage

from fancySVD import IterativeSVD

imputed_matrix = IterativeSVD().fit_transform(matrix)

Algorithms

• IterativeSVD: Matrix completion by iterative low-rank SVD decomposition. Should be similar to SVDimpute from Missing value estimation methods for DNA microarrays by Troyanskaya et. al.
