A dedicated module for **ΔS monitoring** in evaluation pipelines.
|
||
ΔS = semantic distance between query, retrieved content, and gold anchor.
|
||
Tracking thresholds ensures that retrieval and reasoning quality remain **auditable, measurable, and comparable**.
|
||
|
||
---
|
||
|
||
## Why ΔS thresholds matter
|
||
|
||
- **Detect semantic drift**: High ΔS despite “correct” tokens indicates meaning mismatch.
|
||
- **Localize retrieval errors**: Low similarity in meaning even if vector scores look fine.
|
||
- **Evaluate reasoning robustness**: Stable models keep ΔS below the risk boundary across paraphrases.
|
||
- **Flag latent hallucinations**: ΔS >0.60 strongly correlates with unsupported answers.
|
||

|
||
## Core bands
|
||
|
||
| Band | Range | Meaning |
|
||
|------|-------|---------|
|
||
| **Stable** | ΔS < 0.40 | Retrieval and reasoning aligned. Answers should be correct and verifiable. |
|
||
| **Transitional** | 0.40 ≤ ΔS < 0.60 | Risk zone. Minor schema changes or index drift may flip outcomes. |
|
||
| **Critical** | ΔS ≥ 0.60 | High failure probability. Almost always linked to missing context or schema break. |
|
||
|
||
---
|
||
|
||
## Acceptance targets
|
||
|
||
- Per-query: **ΔS ≤ 0.45**
|
||
- Batch average: **≤ 0.40**
|
||
- Allowance: **≤ 10%** of queries can fall in the transitional band (0.40–0.60).
|
||
- Critical: **0% tolerance** for ΔS ≥ 0.60 in gold-set eval.
|
||
|
||
---
|
||
|
||
## ΔS in eval workflow
|
||
|
||
1. **Probe per query**
|
||
Log ΔS(question, retrieved) and ΔS(retrieved, anchor).
|
||
2. **Batch roll-up**
|
||
Compute mean, variance, and percentile distribution.
|
||
3. **Compare across seeds**
|
||
Run three paraphrases and two random seeds; check convergence.
|
||
4. **Drift alerting**
|
||
If ΔS rises >0.05 vs baseline, trigger retraining or schema audit.
|
||
|
||
---
|
||
|
||
## Example probe (pseudo)
|
||
|
||
```python
|
||
def deltaS_probe(query, retrieved, anchor):
|
||
d1 = deltaS(query, retrieved)
|
||
d2 = deltaS(retrieved, anchor)
|
||
return max(d1, d2)
|
||
|
||
for q in eval_set:
|
||
s = deltaS_probe(q.query, q.retrieved, q.anchor)
|
||
if s >= 0.60:
|
||
alerts.append({"qid": q.id, "ΔS": s, "status": "critical"})
|
||
````
|
||

|
||
|
||
## Common pitfalls
|
||
|
||
* **Using cosine similarity as ΔS** → ΔS is semantic distance, not raw vector score.
|
||
* **Ignoring anchor comparison** → must compute against both query and gold span.
|
||
* **No variance tracking** → averages hide volatility; variance is key.
|
||
* **One-shot eval** → without paraphrase/seed checks, thresholds lack reliability.
|
||
|

|
||
|
||
## Reporting recommendations
|
||
|
||
* **ΔS histogram**: visualize stability bands.
|
||
* **Trend line**: track ΔS mean per batch over time.
|
||
* **Baseline delta**: highlight drift from previous eval version.
|
||
* **Failure clustering**: group queries where ΔS ≥0.60 for root-cause analysis.
