How this service works
Issue kind - Top-k label coverage: Top-k label coverage for Issue kind. Up to 200 supplied labelled text records. Local dataset tools, evaluation and small naive-Bayes baselines; no hosted model or foundation-model training. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded top-k label coverage deliverable.
Output
Returns a bounded top-k label coverage deliverable: a metric (or set of metrics) indicating the proportion of supplied labelled records for which the true label appears within the top k ranked predictions by probability, computed over the 4-class issue-kind label set (bug, request, question, other).
Example use cases
Baseline classifier coverage audit
“I trained a naive-Bayes model to classify support tickets as bug, request, question, or other. I have 50 labelled examples with their predicted probabilities. Can you compute top-2 label coverage so I can see how often the right label makes it into the model's top 2 guesses?”
Comparing k=1 vs k=3 thresholds
“For my issue triage classifier, I want to see the difference between top-1 and top-3 label coverage on my 80-record labelled test set. Each record has actual and predicted labels plus four class probabilities. Run top-3 coverage for me.”
Quality gate for issue labelling pipeline
“Before we ship our automated issue labelling pipeline, I need to verify our model's top-2 label coverage meets our 90% threshold. I'll give you 120 labelled issue records with probabilities — can you calculate the top-k coverage with k=2?”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-sector-ml-issue-kind-top-k?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, low-cost top-k coverage evaluation for a 4-class issue-kind classifier without access to a hosted ML platform. Ideal for small dataset audits (up to 200 records), rapid local-style evaluation of naive-Bayes or similar baselines, and scenarios where you already have predicted probabilities and just need the coverage metric computed. Not suitable for training models, handling larger datasets, or multi-class problems beyond the fixed bug/request/question/other taxonomy.
Side effects
- More than 200 records submitted — exceeds maximum batch size
- probabilities array does not contain exactly 4 values per record
- k value outside allowed range of 1–4
- actual or predicted labels outside allowed enum values (bug/request/question/other)
- malformed record missing required fields (id, text, actual, predicted, probabilities)
- payment not received or x402 authentication failure
