Future work proposed included integrating land-use, socioeconomic, and detailed signal timing data; expanding geographic diversity; and advancing formal privacy guarantees like differential privacy at scale.
| Aspect | Description |
|--------|-------------|
| Goal | Develop a scalable pipeline that predicts end‑of‑season grain yield with < 15 % mean absolute percentage error (MAPE) across diverse agro‑ecological zones. |
| Data | - Remote sensing: Sentinel‑2 multispectral imagery (10 m resolution) every 5 days.
- In‑field IoT sensors: Soil moisture, temperature, and nutrient probes (1 Hz sampling).
- Historical agronomic records: Variety, planting date, management practices (≈ 30 yr). |
| Study sites | 12 research farms spanning three climate clusters (Mediterranean, temperate, semi‑arid) in Europe and North America, covering 5 000 ha in total. |
| Model | A hierarchical deep‑learning architecture:
1. Low‑level encoder (CNN) processes satellite patches.
2. Temporal module (GRU) ingests IoT time series.
3. Meta‑learner (gradient‑boosted trees) merges encoder outputs with categorical agronomic metadata. |
| Training & validation | 5‑fold cross‑validation across sites, with a hold‑out year (2020) for out‑of‑sample testing. |
| Key performance metrics | - MAPE: 12.8 % (vs. 15.9 % for the baseline “YieldNet”).
- R²: 0.78 (vs. 0.71).
- Computation time: 3 h per season on a single NVIDIA V100 GPU (≈ 30 % faster than baseline). |
| Open‑source deliverables | - MEYD‑Toolkit (Python package, pip‑installable).
- Docker‑based cloud‑ready pipeline (AWS, GCP).
- Public dataset (2 TB) hosted on Zenodo (doi:10.5281/zenodo.1234567). | meyd873 2021
Concept: A collaborative soundscape built entirely from field recordings contributed by community members in over 30 cities worldwide.
How It Was Built:
Impact: The piece was used as the background score for a short documentary on pandemic life, earning a nomination at the 2022 Indie Sound Awards.
