description	Use when designing or auditing the empirical evaluation for an ICDM (IEEE International Conference on Data Mining) paper - mining-task definition, strong and fairly-tuned baselines, ablations that isolate the named mechanism, scalability curves that test scale claims, and discovery-validity checks that separate real findings from evaluation artifacts.

ICDM Experiments

Design the evaluation an ICDM reviewer will trust: a defined mining task, baselines tuned as carefully as your method, ablations that isolate the mechanism, a measured scale story, and a discovery-validity argument. ICDM's data-centric reviewers punish leaderboard-only wins and un-checkable discovery claims, and the whole evaluation must fit inside the 10-page all-inclusive cap.

Define the mining task before the metric

• State the task operationally: inputs, outputs, and what a correct answer is. "Anomaly detection" is a genre; "rank edges by anomalousness in a one-pass stream, evaluated against injected ground truth" is a task.
• Fix the evaluation protocol — splits, negatives, thresholds, ranking cutoffs — before running anything, and describe it precisely enough to reproduce inside the page cap.

The four evidence axes

Axis	Question it answers	Typical evidence
Quality	Is the mining result good on the task?	Ranking/accuracy vs baselines with variance
Scale	Does the scale claim hold?	Latency/memory curves across data sizes
Mechanism	Is the named mechanism the reason?	Ablations toggling exactly that component
Validity	Is the finding real, not an artifact?	Controlled injections, known-truth checks

A strong ICDM paper touches all four; missing "mechanism" or "validity" is the usual reason a methodologically fine paper reads as thin.

Baselines and tuning symmetry

• Compare against current strong baselines, and tune them with the same budget you gave your method; an under-tuned baseline is the fastest way to lose reviewer trust.
• Include the obvious simple baseline. If a cheap method nearly matches you, say so and argue the regime where your mechanism pays off.
• Report every number with variance over seeded runs; a single-run table invites the "is this noise?" review.

Ablations that isolate the mechanism

The mechanism-attached novelty of icdm-writing-style must be demonstrated, not asserted.

Mechanism: single-pass isolation sketch with m random partitions.
Ablation grid:
  - remove the sketch, keep full storage      -> isolates the streaming contribution
  - vary m (partition count)                  -> maps the accuracy/memory knob
  - swap the hash family                       -> tests sensitivity to the mechanism's core
  - replace isolation score with density score -> isolates the isolation principle
Each row answers "was THIS the reason it worked?"

Test the scale claim, do not assert it

• If you claim scalability, plot behavior across at least an order of magnitude of data size, and report the cost model (linear, sub-linear memory, amortized constant update).
• Separate wall-clock from asymptotic claims; hardware-dependent speedups need the hardware stated and, ideally, an operation count that is not hardware-dependent.

Discovery validity: the ICDM instinct

• Where truth is unknown, build a setting where it is: injected anomalies, planted patterns, synthetic graphs with known structure — so you can show the method recovers known signal.
• Guard against leakage: temporal tasks need time-respecting splits; graph tasks need to avoid train/test edge overlap. State the guard explicitly.
• Do not overclaim when differences are within variance; an honest "matches at lower cost" is stronger here than a fragile "outperforms."

Vignette: an ablation that saved the claim

A team reports strong stream-anomaly numbers but reviewers cannot tell whether the sketch or the underlying isolation criterion did the work. Adding two ablation rows — full-storage isolation (isolating the streaming contribution) and a density-score swap (isolating the isolation principle) — showed the sketch preserved batch quality while the isolation principle drove detection. The claim survived because the mechanism was shown, not stated, and both rows fit in the appendix inside the 10-page cap.
