Pseudocode No The paper does not contain structured pseudocode or algorithm blocks.
Open Source Code No The paper does not provide concrete access to source code for the methodology described in this paper.
Open Datasets Yes We evaluate experimentally the A-I recommender System on a movie dataset extracted from the Netflix dataset2 and imdbapi3.
Dataset Splits Yes Further, in our experiments we vary the number of users in the training set, considering all users who have rated at least 10 movies or, alternatively, 20 movies, and make predictions for users who have rated fewer than 10 or 20 movies, respectively (in other words these users are part of our test set). To address the cold-start problem, our training sets also include 5, 7 or 10 movies for users who have rated fewer than 10 or 20 movies, with these (5, 7 or 10) movies not included in the test sets.
Hardware Specification No No specific hardware details (e.g., GPU/CPU models, memory amounts, or detailed computer specifications) used for running experiments are provided.
Software Dependencies No The paper mentions 'Suprise library [Hug, 2017]' but does not provide a specific version number for the software dependency.
Experiment Setup Yes In our experiments, we use the following constants for the profile of all users u U: µu c.f. = 0.3, µu genre = 0.3, µu actor = 0.5, µu director = 0.2, and, to determine the similarity constants between any two (different) users, we use the cosine distance between the users preferences for all aspects of type genre.
