BFLP: An Adaptive Federated Learning Framework for Internet of Vehicles

Algorithm 3

Vertical federated learning.

	Input: η
	Output: ρ1, ρ2, …, ρT
	1: Party P^t(t = 1, 2, …, T) initialize ρ1, ρ2…ρT;
	2: Exchange P^t(t = 1, 2, …, T);
	3: for each iteration x = 1, 2, …do
	4:  Randomly sample a minibatch
	5:  for each party t = 1, 2, …, T sequentially do
	6:   for each local iteration r = 1, 2, …, Q do
	7:    t computes using (9);
	8:    update ;
	9:   end for
	10:     Exchange P^t (t = 1, 2, …, T);
	11:    end for
