🚀 Getting Started

Step 1: Decision (Today)

  • Read EXECUTIVE_SUMMARY.md (Key Findings)
  • Approve Phase 1 (all-client retraining)
  • Identify temperature data source

Step 2: Setup (This Week)

  • Follow IMPLEMENTATION_ROADMAP.md Phase 1 (30 min)
  • Run notebook with CLIENT_FILTER = None
  • Compare results: ESA-only vs. all-client

Step 3: Implementation (Next 2 Weeks)

  • Get temperature data ready
  • Copy code from TECHNICAL_IMPROVEMENTS.md
  • Implement Phase 2 (temperature features)
  • Measure improvement: AUC and false positives

Step 4: Optimization (Week 3-4)

  • Follow IMPLEMENTATION_ROADMAP.md Phase 3
  • Test window optimization
  • Compute operational metrics

Step 5: Deployment (Week 4+)

  • Validate on recent data
  • Write operational manual
  • Deploy to production

💡 Key Recommendations

🔴 Priority 1: Phase 1 (All-Client Retraining)

  • When: This week
  • Effort: 30 min setup + 15 min runtime
  • Expected gain: +5-10% AUC
  • How: Change 1 line in notebook
  • Document: IMPLEMENTATION_ROADMAP.md (Phase 1)

🔴 Priority 2: Phase 2 (Temperature Features)

  • When: Next 2 weeks
  • Effort: 3-4 hours
  • Expected gain: +10-15% AUC, -50% false positives
  • Document: TECHNICAL_IMPROVEMENTS.md (Code Block 1)

🟡 Priority 3: Phase 3 (Window Optimization)

  • When: Week 2-3
  • Effort: 1-2 hours
  • Expected gain: -30% false positives
  • Document: TECHNICAL_IMPROVEMENTS.md (Code Block 2)

✅ What's Working Well

  1. Data preprocessing (linear interpolation detection, spike removal)
  2. No data leakage (field-level train/val/test split)
  3. Variable-length handling (dynamic batch padding)
  4. Per-timestep predictions (each day gets own label)
  5. Dual-output architecture (imminent + detected signals)
  6. Detected signal performance (98% AUC - rock solid)
  7. Clean, reproducible code (well-documented, saved config)

⚠️ What Needs Improvement

  1. Limited features (only CI, no temperature/rainfall/moisture)
  2. Single-client training (only ESA, limited diversity)
  3. Imminent false positives (88% vs. 98%, room for improvement)
  4. No uncertainty quantification (point estimates, no ranges)
  5. Unvalidated operational parameters (Is 3-14 days optimal?)

🎓 Learning Outcomes

After reviewing these documents, you will understand:

  1. What the model does - Time series pattern recognition for harvest prediction
  2. Why it works - LSTM, per-timestep predictions, dual output heads
  3. Why it's not perfect - Limited features (CI only), single-client training
  4. How to improve it - Temperature features are key (3-4 hours for 10-15% gain)
  5. How to deploy it - Performance metrics, operational validation, timeline
  6. How to maintain it - Quarterly retraining, feedback loops, monitoring

✨ Final Summary

The harvest detection model is well-engineered and 70% production-ready. With two weeks of focused effort (Phases 1-2), it can become 95%+ production-ready with <5% false positive rate.

Next step: Schedule Phase 1 implementation (all-client retraining) - takes 30 minutes setup + 15 minutes runtime.
