Canary Edge ships with a powerful generic model that works out of the box. For production workloads, setting a baseline for each machine fine-tunes a dedicated predictor that learns the specific patterns of your equipment.

​
When to Set a Baseline

  • Your time series has unique seasonal patterns
  • The generic model produces too many false positives
  • You need maximum sensitivity for critical equipment
  • You want regime classification (HEALTHY/ACTIVE/TRANSITION/SHOCK)

​
How It Works

  1. Send normal operating data via POST /v1/baseline with a machine_id
  2. Canary Edge computes energy statistics and trains a lightweight predictor (~462K params) in seconds
  3. Future detection calls with that machine_id use the fine-tuned model automatically
  4. Detection accuracy typically improves from ~82% (generic) to 97%+ (fine-tuned)

​
Setting a Baseline

curl -X POST https://api.canaryedge.com/v1/baseline \
  -H "Content-Type: application/json" \
  -H "Ocp-Apim-Subscription-Key: YOUR_API_KEY" \
  -d '{
    "machine_id": "pump-assembly-1",
    "energies": [0.12, 0.15, 0.11, 0.13, 0.14, 0.12, 0.16, 0.11, ...]
  }'
Only send energy scores from normal operating data for baseline creation. Including anomalous data will degrade detection accuracy.

​
Checking a Baseline

curl "https://api.canaryedge.com/v1/baseline?machine_id=pump-assembly-1" \
  -H "Ocp-Apim-Subscription-Key: YOUR_API_KEY"
Response: 
{
  "machine_id": "pump-assembly-1",
  "mean": 0.132,
  "std": 0.018,
  "p99": 0.187,
  "sample_count": 500,
  "created_at": "2026-03-15T10:00:00Z"
}

​
Requirements

  • Minimum 100 energy values for a reliable baseline
  • Data should represent at least one full operational cycle
  • All data should be from normal, healthy operation

​
Machine Status

Once a baseline is set, check machine status: 
curl "https://api.canaryedge.com/v1/status/pump-assembly-1" \
  -H "Ocp-Apim-Subscription-Key: YOUR_API_KEY"

​
Deleting a Machine

To remove a baseline and revert to the generic detector: 
curl -X DELETE "https://api.canaryedge.com/v1/machines/pump-assembly-1" \
  -H "Ocp-Apim-Subscription-Key: YOUR_API_KEY"
