We study the practical consequences of dataset sampling strategies on the performance of recommendation algorithms. Recommender systems are generally trained and evaluated on samples of larger datasets. Samples are often taken in a naı̈ve or ad-hoc fashion: e.g. by sampling a dataset randomly or by selecting users or items with many interactions. As we demonstrate, commonly-used data sampling schemes can have significant consequences on algorithm performance—masking performance deficiencies in…

On Sampling Strategies for Neural Network-based Collaborative Filtering

A general neural network-based recommendation framework is proposed, which subsumes several existing state-of-the-art recommendation algorithms, and the efficiency issue is addressed by investigating sampling strategies in the stochastic gradient descent training for the framework.

Self-Attentive Sequential Recommendation

Extensive empirical studies show that the proposed self-attention based sequential model (SASRec) outperforms various state-of-the-art sequential models (including MC/CNN/RNN-based approaches) on both sparse and dense datasets.

Off-policy Bandits with Deficient Support

This work systematically analyzed the statistical and computational properties of three approaches that provide various guarantees for IPS-based learning despite the inherent limitations of support-deficient data: restricting the action space, reward extrapolation, and restricting the policy space.
