elliot.recommender.latent_factor_models.WRMF.wrmf module

Module description:

class elliot.recommender.latent_factor_models.WRMF.wrmf.WRMF(data, config, params, *args, **kwargs)

Bases: elliot.recommender.recommender_utils_mixin.RecMixin, elliot.recommender.base_recommender_model.BaseRecommenderModel

Weighted XXX Matrix Factorization

For further details, please refer to the paper

Parameters

• factors – Number of latent factors

• lr – Learning rate

• alpha –

• reg – Regularization coefficient

To include the recommendation model, add it to the config file adopting the following pattern:

models:
  WRMF:
    meta:
      save_recs: True
    epochs: 10
    factors: 50
    alpha: 1
    reg: 0.1

get_recommendations(k: int = 10)

get_single_recommendation(mask, k, *args)

property name

train()
