Since 2010, we have built and maintained LensKit, an open-source toolkit for building, researching, and learning about recommender systems. We have successfully used the software in a wide range of recommender systems experiments, to support education in traditional classroom and online settings, and as the algorithmic backend for user-facing recommendation services in movies and books. This experience, along with community feedback, has surfaced a number of challenges with LensKit's design and…

TLDR
This work will compare nine different algorithms used for generating recommendations across seven different metrics and provide a detailed and clear explanation of the methodology carried out as well as the experimental setup in order to ensure future reproducibility.
DRecPy: A Python Framework for Developing Deep Learning-Based Recommenders
TLDR
This work introduces a new framework that not only provides several modules to avoid repetitive development work, but also to assist practitioners with these existing challenges.
Using Research Literature to Generate Datasets of Implicit Feedback for Recommending Scientific Items
TLDR
A methodology that explores scientific literature for generating utility matrices of implicit feedback for recommending scientific items is proposed, and is in principle applicable to Recommender Systems in any scientific field.
Algorithm Selection with Librec-auto
Due to the complexity of recommendation algorithms, experimentation on recommender systems has become a challenging task. Current recommendation algorithms, while powerful, involve large numbers of
Standing in Your Shoes: External Assessments for Personalized Recommender Systems
TLDR
The findings show that external assessments can be used for assessing user preference labels and evaluating systems in personalized recommendation scenarios, even better than traditional history-based online evaluation.
Modeling uncertainty to improve personalized recommendations via Bayesian deep learning
TLDR
An approach based on Bayesian deep learning to improve personalized recommendations by capturing the uncertainty associated with the model output and utilizing it to boost exploration in the context of Recommender Systems.
Estimating Error and Bias in Offline Evaluation Results
TLDR
It is found that missing data in the rating or observation process causes the evaluation protocol to systematically mis-estimate metric values, and in some cases erroneously determine that a popularity-based recommender outperforms even a perfect personalized recommender.
Fairness-aware Recommendation with librec-auto
TLDR
Fairness-aware enhancements to the recommender systems experimentation tool librec-auto are described, which include metrics for various classes of fairness definitions, extension of the experimental model to support result re-ranking and a library of associated re- ranking algorithms, and additional support for experiment automation and reporting.

TLDR
This paper presents an approach based on Bayesian Deep Learning to learn a compact representation of user and item attributes to guide exploitation and shows how to further boost exploration by incorporating model uncertainty with that of data uncertainty.

TLDR
Details of pyRecLab are introduced, showing as well performance analysis in terms of error metrics (MAE and RMSE) and train/test time, and it is benchmarked against the popular Java-based library LibRec, showing similar results.
When recommenders fail: predicting recommender failure for algorithm selection and combination
TLDR
This work presents an analysis of the predictions made by several well-known recommender algorithms on the MovieLens 10M data set, showing that for many cases in which one algorithm fails, there is another that will correctly predict the rating.
All The Cool Kids, How Do They Fit In?: Popularity and Demographic Biases in Recommender Evaluation and Effectiveness
TLDR
System evaluation protocols that explicitly quantify the degree to which the system is meeting the information needs of all its users are proposed, as well as the need for researchers and operators to move beyond evaluations that favor the needs of larger subsets of the user population while ignoring smaller subsets.
Surprise: A Python library for recommender systems
Recommender systems aim at providing users with a list of recommendations of items that a service offers. For example, a video streaming service will typically rely on a recommender system to propose

TLDR
A methodology is described that is used to compare representatives of three common families of algorithms along eleven different metrics and finds that for the first few ratings a baseline algorithm performs better than three common collaborative filtering algorithms.
