Updating rules for E, H, R and F.
| Step | Calculation |
| 1: | Initialize E and R with nonnegative matrix randomly | 2: | loop | 3: | loop | 4: | Update H as in Equation (16) | 5: | forl = 1 to Mn | 6: | fork = 1 to p | 7: | Update Elk as in Equation (17) | 8: | end | 9: | end | 10: | end loop until convergence | 11: | Update F as in Equation (29) | 12: | forg= 1 to n | 13: | for w = 1 to q. | 14: | Update Rgw as in Equation (30) | 15: | end | 16: | end | 17: | end loop until convergence |
