some results running on the linux laptop with the new model:
liu@arunr-Inspiron-5548:~/code$ python3 newlfmodelradius.py /home/liu/.local/lib/python3.5/site-packages/sklearn/cross_validation.py:41: DeprecationWarning: This module was deprecated in version 0.18 in favor of the model_selection module into which all the refactored classes and functions are moved. Also note that the interface of the new CV iterators are different from that of this module. This module will be removed in 0.20. "This module will be removed in 0.20.", DeprecationWarning) this is test for new lightfm, 10000 checkins,and radius as 10 unique user&venue checkin combination in test 1414 unique user&venue checkin combination in test 5654 max num in matrix 14 max num in train 13 I am beginning to get negtive examples object preprocess created get neighbor time used: 1896.430985 Time used for negative examples: 1908.565092 I am beginning to model,this is the new model model has been fitted this is the model that consider the checkin times Time used: 0.7560190000001512 Train_auc is 0.545424 test auc is 0.465073
the same data with the original lightfm model:
