• scripts/plot.ipynb analyzes log file for the data
• cargo run --release --bin report 2>&1 | tee log.txt run this from ./ranking to produce a log file
• compute_ratings has new functions & objects RatingSystem::compute_metrics, PerformanceReport, predict_performance
• Currently two metrics implemented: inverted-pairs and percentile (normalized average rank distance)
• ranking/src/bin/report.rs has the code for generating performance reports. Grid search used for hyper-parameter optimization
