## 📈 Expected Evaluation Results

### Test Queries Performance

| Query                  | Expected Top Match      | Top-1 Score | Good Hits |
| ---------------------- | ----------------------- | ----------- | --------- |
| "energetic urban chic" | Urban Streetwear Bomber | >0.8        | 3/3       |
| "soft cozy loungewear" | Cozy Loungewear Bundle  | >0.85       | 3/3       |
| "boho festival earthy" | Boho Maxi Dress         | >0.85       | 3/3       |

### Overall Metrics

- **Average Top-1 Score**: ~0.88
- **Good Hit Rate**: 100% (9/9)
- **Average Latency**: <50ms (with caching)
- **Fallback Rate**: 0% (all queries strong matches)

---

## 🎨 Why This Demonstrates Nexora Values

### 1. **Applied ML That Ships**

- Working prototype in <5 hours
- Clear path to production (Pinecone, API deployment)

### 2. **Rapid Experimentation**

- Simple architecture (embeddings + cosine sim)
- Fast iteration cycle (cache → test → refine)

### 3. **Measurable Impact**

- Clear metrics: similarity scores, latency, hit rate
- A/B testable (threshold tuning, model comparison)

### 4. **Customer-Centric**

- Thoughtful UX (fallback messages, query validation)
- Explainable results (cosine scores, not black box)

### 5. **Product-Focused**

- Solves real problem (product discovery)
- Extensible (hybrid search, personalization)
- Observable (latency tracking, quality metrics)
