A community/hub for players to connect and interact

Founded in 2010, N-Party is a community to players to connect and interact with other players by throught local and digital experience. By using N-Party website, the users can lookup for groups of people to play video-game, join or manage championships, and even write news and articles about the video-game industry. The user has a gamefied profile, gaining experience, levels and badges by interacting with the group experience.

This project is currently in WIP, as the website had been turned down, and we had to bring data together for backup reasons. But in the next weeks, we are planing to bring the best digital experience that a gaming community can create.

This article shows the results of a performance analysis from LSTM, GRU and Hybrid Neural Network architectures in Recommendation Systems. To this end, prototypes of the networks were built to be trained using data from the user's browsing history of a streaming website in China. The results were evaluated using the metrics of Accuracy, Precision, Recall and F1-Score, thus identifying the advantages and disadvantages of each architecture in different approaches.
