This adds a dataset based off the lastfm360K dataset, using factors generated by a simple MF based recommendation model. This lets us replicate the experiments done in this post: http://www.benfrederickson.com/approximate-nearest-neighbours-for-recommender-systems/

This is excellent – thanks for contributing. Will include it in the next round of benchmarks! |
|
(separately I should probably figure out a way to run the dataset code as a part of the CI) |
|
will generate a dataset and upload it shortly |

Sorry for the late realization but I never linked to this from the README. adding that now as a part of #166 |

This lets us replicate the experiments done in this post: http://www.benfrederickson.com/approximate-nearest-neighbours-for-recommender-systems/ , with the main benefit that this lets us test out inner product lookup of MF based recommender models on top of angular ANN indices.
The generated dataset is here https://github.com/benfred/recommender_data/releases/download/v1.0/lastfm-64-dot.hdf5
