WebFeb 28, 2024 · Greedy algo steps in to compute additive function h1 between rows of the X. The split with lowest SSE is chosen to fit h1 on F0. The residuals of F1 are calculated (Y — F1). WebSpecifically, we formulate a cost function and a greedy-based grouping strategy, which divides the clients into several groups to accelerate the convergence of the FL model. The simulation results verify the effectiveness of FLIGHT for accelerating the convergence of FL with heterogeneous clients. Besides the exemplified linear regression (LR ... pork belly oklahoma city
