Table 1 The pseudocode of MHSNMF

Input: \( \left\{{V}^1,{V}^2,\cdots, {V}^{n_v}\right\} \), γ^v_, α^v_, k

Output: \( \left\{{H}^1,{H}^2,\cdots, {H}^{n_v}\right\} \), H^∗_, α^v

1. Transforming each Vⁱ to Aⁱ according to Eqs.3, 4 and 5

2. Solving the Hessian matrix Bⁱ for each view Vⁱ

3. Initializing Hⁱ_, H^∗_, α^v = 1/n_v

4. Iteration beginning

For i = 1 : n_v,

Fixing H^∗_, α^v_, updating H^v according to Eq. 14

Fixing H^v_, α^v_, updating H^∗ according to Eq. 16

Learning α^v according to Eq. 21

Until all views have been updated

5. Repeating
