Challenge

LlamaIndex Infrastructure Noise & Benchmark Variance Analyzer

Infrastructure noise such as noisy neighbors and network jitter obscures true performance improvements in agentic benchmarks. Build a LlamaIndex RAG and workflow framework that indexes benchmark execution logs, computes statistical variance confidence intervals, and isolates true algorithmic progress from hardware noise.

Evaluation rubric

How submissions are scored

These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.

Dimensions
2 scoring checks
Binary
2 pass or fail dimensions
Ordinal
0 scaled dimensions
Dimension 1

significance_test_accuracy

Ensures correct determination of statistical significance.

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Dimension 2

noise_identification_f1

F1-score for identifying specific root causes of infrastructure noise • target: 0.94 • range: 0.85-1

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
