Daily progress

RMSE over time · lower is better. Dots are daily evaluations, not GitHub activity. Failed runs leave gaps; no submission means no point.

Results

Scores use hidden evaluation ratings; the input contains train + test. Accuracy is the percentage of exactly predicted ratings. These measurements support your analysis; code itself is not graded.

BestOf references are preserved benchmarks from previous years. Their current scores are recomputed with this platform; archived scores remain in the history.

Run 20261004T030001Z · Execution limit: 1200 s per group. Student runs: 4 CPU threads · 12 GiB host memory · CPU only. Historical references use one A40 GPU when required. Dependency installation time is not included in the reported execution time.
