  • Recommender systems are a growing area of research that find practical applications in a variety of domains. Integrated library systems and location-based social networks can apply recommendation algorithms to assist their users in finding an item or location that suits their needs. With an ever-increasing variety of options to choose from, deciding on which book to read or movie to watch can become overwhelming. Recommender systems aid their users in the decision making process by providing a list of items likely to be relevant to the user's needs and interests. A persistent issue faced by recommender systems is a lack of data concerning the preferences of its users, known as the "cold-start" problem, which leads to poor recommendation quality, particularly for new users and items. To improve recommendation quality in the face of incomplete data, we propose several novel approaches for incorporating all available data into collaborative filtering algorithms.
