Systems and methods for maintaining vectors of values associated with a plurality of media assets

摘要

The application relates to systems and methods for maintaining vectors of values associated with a plurality of media assets. A user equipment device receives a first vector of values for a first media asset and a second vector of values for a second media asset. The user equipment device determines whether a user has viewed both the first and second media assets and in response to determining that the user has viewed both assets, the user equipment device determines a modelled similarity value representing modelled similarity between the first and second media assets. The user equipment device then retrieves an observed similarity value representing observed similarity between the first and second media assets based on metadata and usage data for the assets and the user equipment device determines a modelling error value based on the modelled similarity value and the observed similarity value. The user equipment device updates the first vector of values and the second vector of values based on the modelling error value and the user equipment device then sends the updated first vector of values and the updated second vector of values to a storage device.
