How this service works
Training question - Top-k label coverage: Top-k label coverage for Training question. 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
A bounded top-k label coverage deliverable: a computed coverage score indicating the fraction of records where the true label appears among the top k highest-probability predictions, given the supplied labelled text records and their classifier probability outputs.
Example use cases
Evaluating educational content classifier
“I've got 50 labeled training question records — each tagged as concept, procedure, example, or assessment — along with my model's predicted label and 4-class probability scores. Can you calculate the top-3 label coverage to see how often the true label falls within the top 3 predictions?”
Comparing top-k thresholds for QA pipeline
“I'm tuning a quiz question classifier and want to know the top-2 label coverage across my 30 labeled samples. Each record has actual and predicted labels plus a 4-value probability array. Can you run the top-k coverage calculation with k=2?”
Benchmarking naive-Bayes baseline model
“We built a naive-Bayes baseline for classifying training questions into concept, procedure, example, and assessment. I have 80 labeled records with their probability outputs — can you compute the top-1 label coverage to see how accurate our baseline is?”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-sector-ml-training-question-top-k?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, inexpensive top-k label coverage metric for a small batch of up to 200 labelled text records in the training question domain with a fixed four-class label set (concept, procedure, example, assessment). Ideal for evaluating naive-Bayes or similar baseline classifiers on educational content without needing a hosted model or foundation model infrastructure.
Side effects
- Invalid k value outside range 1-4 returns error
- Records array exceeding 200 items rejected
- Probability arrays not summing correctly or containing values outside 0-1 may cause errors
- Invalid label values outside the four allowed enums (concept, procedure, example, assessment) return validation errors
- Empty records array returns error or trivial result
- Payment failure via x402 protocol prevents response
