An Engagement Model Based on User Interest and QoS in Video Streaming Systems

Algorithm 1

Extraction and Inference (E-I) interest estimation algorithm.

Step I (extraction). Extract users’ interest from their engagement records in the Smooth sessions

where users did not experience any quality problems including buffering event or start-up delay.

Step II (inference). Based on the extracted interest records in Step I, infer users’ interest in other sessions.
