今天是聯合國 #國際糧食損失和浪費問題宣傳日！！
根據聯合國糧農組織(FAO)統計，全世界每年有3分之1、約13億噸的糧食被浪費掉，糧食損失與浪費造成自然資源的消耗與碳排放量的增加，加劇極端氣候。
在台灣，透過媒合網站、食物銀行以及惜福超市，從生產、製造到消費，我們在解決糧食損失與浪費走在前端，實踐了聯合國「永續發展目標（SDGs）」第12項目標「確保永續的消費與生產模式」以及第2項目標「消除飢餓，達成糧食安全，改善營養及促進永續農業」。
台灣是實踐聯合國永續發展目標的模範生，我們希望透過這部影片，呼應聯合國「國際糧食損失與浪費問題宣傳日」，減少糧食浪費，就從你我做起。
#永續發展目標 #SDG12 #確保永續的消費與生產模式 #SDG2 #消除飢餓達成糧食安全改善營養及促進永續農業
Do you know what today is? It’s the UN International Day of Awareness of Food Loss and Waste! According to statistics from the Food and Agriculture Organization of the United Nations, around a third of food around the world goes to waste every year; that’s around 1.3 billion tonnes! This also means extra carbon emissions and depletion of natural resources, contributing to #ClimateChange.
#Taiwan has come up with a whole host of innovative ideas to reduce food loss from upstream producers, all the way down to the consumer. Check out the video below to find out more about one such initiative, websites which facilitate the distribution of surplus agricultural produce from farmers and supermarkets to people in remote areas and vulnerable groups through food banks.
This initiative is in line with both #SDG2 #ZeroHunger and #SDG12 #ResponsibleConsumptionAndProduction and we hope that by 2030 food waste by consumers can be reduced by 50% as well as reducing food loss in supply chains.
Taiwan’s vision of global partnership on the issue of #FoodWaste can serve as a reference for the UN in attaining the SDGs!
distribution統計 在 [問題] 什麼是Underlying distribution - 看板Statistics - 批踢踢 ... 的推薦與評價
小弟最近剛接觸統計和機器學習的時候常常會看到一句話
「Assume data are drawn from an underlying distribution」
請問這裡的underlying distribution指的是probability distribution嗎？
如果指的是probability distribution，那相對應的experiment及sample space是什麼呢
？
因為在小弟的認知下，使用機率之前必須先訂定experiment以及sample space
但我想不出這裡的experiment和sample space是什麼，書上也沒說明
希望大家能幫我解惑，謝謝
