Algorithm 2.1.

Discriminative SCCA (DSCCA)

Require:
	X = {x1, …, xn}, Y = {y1, …, yn}, Lw ⊆ ℜn×n, Lb ⊆ ℜn×n
Ensure:
	Canonical vectors u and v.
1:	t = 1, Initialize ut ∈ ℜp×1, vt ∈ ℜq×1;
2:	while not converge do
3:	Solve Eq. (5) using Nesterov’s method and obtain u;
4:	Solve Eq. (6) using Nesterov’s method and obtain v;
5:	Scale u so that uTu = 1
6:	Scale v so that vTv = 1
7:	t = t + 1.
8:	end while
