Title: Just-for-Me: Towards Intelligent Location-Aware Social Music Recommendation

Abstract:  As the building block of any living organisms, the cells enjoy an amazing capability to adapt themselves to the environment changes. However, this is very challenging for the existing music recommender systems, especially those under mobile environment. While a large amount of research efforts have been invested in the promising field, the technology is still in its infancy. One of key reasons is that current solutions suffer from the inability to effectively take multiple kinds of contextual information into account. In this talk, I shall introduce Just-for-Me recommender system with a layered structure based on advanced audio analytics scheme and topic model. This architecture enables 1) straightforward and effective incorporation of multiple contextual information about location and global popularity trend and 2) systematically overcome cold-start and sparsity problems. An extensive experimental study demonstrates that Just-for-Me system can significantly improve the recommendation quality from different aspects (e.g., accuracy and robustness) over various geo-locations.
