12. Stage 1: Global Similarity Classification (cont’d) We maintain N x N table K where each entry k i,j is defined as similarity rate between users i and j:
13. Stage 2: Localized Update The overall cost functions for Localized Update before and after each iteration are respectively: where U (U') : Set of users G (G') : Set of multicast groups S (S') : Set of flows of interest (sources) X (X') : Flow-to-group-mapping matrix Y (Y') : Subscription matrix γ ( γ ') : Multicast group routing overhead and maintenance expenses
