Frostwise — know your frost dates, plant with confidence

说明与用途

Frostwise 通过 TabPFN 和 ERA5 气候数据计算精准霜冻日期，并生成种植日历，帮助园丁自信规划，避免作物损失。

问题

Gardeners lack accurate, location‑specific frost dates, leading to crop loss.

结果

Frostwise delivers accurate, hyperlocal frost dates and planting plans without proprietary APIs, enabling gardeners to plant confidently.

工作流

• 1. User enters city or selects sample location.
• 2. Backend fetches 2005–2024 daily minimum temperatures from Open‑Meteo ERA5 archive for that location.
• 3. TabPFN performs an in‑context prediction: a classifier decides if frost occurs, two regressors output last spring and first autumn frost day‑of‑year.
• 4. The app generates a planting calendar for 12 common crops, anchoring sow windows to the predicted frost dates and adding crop notes.
• 5. Result is displayed in a clean single‑page UI; static demo precomputes predictions for offline use.

证据

Frostwise — a hyperlocal garden planner that computes your frost dates from real climate history using TabPFN, the open‑source tabular foundation model — then turns them into a planting plan you can actually follow.

At request time, TabPFN performs the whole prediction in‑context: a classifier for frost/no‑frost, two regressors for the dates — a single forward pass per model, no gradient training.

The real challenge was making the AI genuine instead of decorative. A frost date isn't in any API — it has to be derived, so I built the entire label pipeline from raw reanalysis data...
