Results of applying Hard-Impute to the Netflix data. The computations were done on a Intel Xeon Linux 3GHz processor; timings are reported based on MAT-LAB implementations of PROPACK and our algorithm. RMSE is the root mean squared error over the probe set. “train error” is the proportion of error on the observed dataset achieved by our estimator relative to the zero estimator.
| rank | time (hrs) | train error | RMSE |
|---|---|---|---|
| 20 | 3.3 | 0.217 | 0.986 |
| 30 | 5.8 | 0.203 | 0.977 |
| 40 | 6.6 | 0.194 | 0.965 |
