v0.2.2

Improvements

• Expand user path (~) on DB dataset
• Change null interaction pair generator to sample uniformly. This changes the way null interaction pairs are sampled so that in-dataset null pairs (pairs with lower interaction value than the threshold) and out-of-dataset null pairs are sampled uniformly.

Bugfixes

• Fix select_random_generator returning non-int internal ids, that was producing issues with data sampling

Others

• Update urllib3 dev dependency due to vulnerabilities (CVE-2019-11324, CVE-2018-20060)
