    【2020農業開放資料論壇】悠由農:農產數據科學經驗分享 - 【農業智庫報導】PI阿柴, Shaw Wu === ###### tags: `COSCUP2020` `入門` `TR209` {%hackmd 7CD4pdKQTa2p6Y3VqH3VrQ %} ``` 主題: 農產數據科學經驗分享 講者: 吳君孝 ``` [悠由金錢報](https://aginteller.datayoo.com.tw/) [阿龜微氣候](https://agriweather.beehivedt.com/) [^1] 開放資料轉變為有價值的服務 並向使用者收費 - 農產業數據應用 - 農產交易預測 - 作物產地分析 和你想的不一樣: - 很多已存的農民覺得巡田很好,健身 數位銷售 打開新的數位渠道、通路 資料透明化後 能做的事情非常多 - e.g. 當產地價格大跌時但終端的價格微跌時其利差擴大 開源的好處 交流 ## 悠遊農預測系統 悠遊農預測系統:結合作物模型演算法、栽培模式與巨觀微觀的氣候資料,產量預測。目前有香蕉田預測案例 - 用歷史資科(生理資料如品種、土壤等)預測比用 sensors 直接測更划算,精準度在一天內 > 農業資料的缺值很多,需要注意這些缺值的處理如刪去、或是用 Deep Learning 的方式補值 數據收集需要應用生農學院傳統課程,進行實驗設計 種田當中已經在做實驗了 現況分析> 原因分析> 實際解決執行能力 將田間狀況數據化 ![](https://i.imgur.com/QE5uqdJ.jpg) ### 應用案例 - 憑據經驗、加上新的分析結果,相互合作 - 根據科學數據進行修正決策! - 從數據面去看,改變的是什麼(例:露天栽培無法控制雨量) - 給水是看土壤含水量再去灑的,品質可以到比較標準的狀態 - 鳳梨 - 規格品比率提升30%(從50% -> 80%) - 鼓聲果 vs 肉聲果(8%→1%) - 傳統經驗推測下雨影響品質轉變 - 蒐集數據後,發現下雨與品質相關係數低(R:0.23) - 找出**關鍵參數**:土壤含水量 - 鳳梨的果實發育是在半夜 - 番茄 - 小番茄平均果重提升16%、每株產量提升18% - 三段法:現況>原因>執行 - 落實作物生理與資料分析的結合 - **關鍵參數**:溫度、光照、電導度 - 薑田 - 生產成本省下25% - 噴灌設備科學化效益評估 - 貴不一定好,應以量測結果(e.g. 土壤保水度)評估 - 不同生產作物應該有不同澆灌方式 - 與傳統數據公司差異: - 新系統可以立即性反饋,滾動式修正 思考設計解決的方法 透過交流的方式 跨領域協作 ### Q&A Q: 領域知識如何補足 A: 請教專家補足 Q: 如何跟客戶收錢 A: 經驗技術轉化累積、case by case - 顧問費:按照作物與年份來收 - 價格服務:採訂閱制 - 產地作物新增數位通路 Q: 如何說服業主打造可用資料科學解決痛點的硬體環境 A: 根據需求與他想賣的價格,算一個業主 affordable 的 solution ,並約定一個時間(如3年),來驗收。 Q: 如何判斷鳳梨為肉聲果 A: 靠經驗、聲波、敲敲看、科技方面:光譜儀 marketing、business model是做儀器關鍵 [^1]: 吳君孝已於2019年6月離開阿龜微氣候團隊
