Understanding PTHC and Top Sites:
S_content(i): Dot‑product between item embedding e_i and a global query vector q (learned via pairwise RankNet loss).S_collab(i,u): Matrix‑factorization score using user latent vector p_u (updated online via stochastic gradient descent).S_fresh(i): Decay functionexp(-λ·Δt_i)whereΔt_iis the age of the item.
