Information filtering via biased heat conduction
Heat conduction process has recently found its application in personalized
recommendation [T. Zhou et al., PNAS 107, 4511 (2010)], which is of high
diversity but low accuracy. By decreasing the temperatures of smalldegree
objects, we present an improved algorithm, called biased heat conduction (
BHC), which could simultaneously enhance the accuracy and diversity.
Extensive experimental analyses demonstrate that the accuracy on MovieLens,
Netflix and Delicious datasets could be improved by 43.5%, 55.4% and 19.2%
compared with the standard heat conduction algorithm, and the diversity is
also increased or approximately unchanged. Further statistical analyses
suggest that the present algorithm could simultaneously identify users’
mainstream and special tastes, resulting in better performance than the
standard heat conduction algorithm. This work provides a creditable way for
highly efficient information filtering. |
