Start with the benchmark source at src/benchmarks/real-world/Microsoft.ML.Benchmarks/KMeansAndLogisticRegressionbench.cs#L24-L53 and reproduce it using scripts/benchmarks_ci.py with the provided filter. Compare the reported baseline and test results with the linked history and report. The issue does not define a code change or completion criteria, so triage must establish what, if anything, should be changed.
