Information filtering via preferential diffusion
Recommender systems have shown great potential to address information
overload problem, namely to help users in finding interesting and relevant
objects within a huge information space. Some physical dynamics, including heat
conduction process and mass or energy diffusion on networks, have recently
found applications in personalized recommendation. Most of the previous studies
focus overwhelmingly on recommendation accuracy as the only important factor,
while overlook the significance of diversity and novelty which indeed provide
the vitality of the system. In this paper, we propose a recommendation
algorithm based on the preferential diffusion process on user-object bipartite
network. Numerical analyses on two benchmark datasets, MovieLens and Netflix,
indicate that our method outperforms the state-of-the-art methods.
Specifically, it can not only provide more accurate recommendations, but also
generate more diverse and novel recommendations by accurately recommending
unpopular objects.Comment: 12 pages, 10 figures, 2 table

Lo Family: William Yang (Youth)
Seeing San Francisco for the first time, at the age of three, after immigrating from Loas will always be a special memory for William Yang now age 16. The sky scrapers of San Francisco were a great contrast to the jungles and life he had just left. In Laos, he lived with his family in a typical rural village where the houses were made of bamboo, thatched roofs and had dirt floors. The villagers would work in their fields to gather food, which they cooked on an open fire. Leaving his parents behind, accompanied only by his grandfather, the trip to America was indeed a great adventureâŠhttps://scholarlycommons.pacific.edu/ss-ha/1005/thumbnail.jp
