Amazon Forecast 現在支援針對 10 倍以上的項目產生預測
aws@amazon.c · 2020-07-09 · via Recent Announcements

張貼日期: Jul 7, 2020

Amazon Forecast 是一種全受管服務,可使用機器學習 (ML) 來產生準確的預測,而無需任何之前的 ML 體驗。Amazon Forecast 適用於各種使用案例,包括產品需求預測、庫存規劃、人力規劃和雲端基礎設施用量預測。

今天,我們很高興地宣佈 Amazon Forecast 現在可為多 10X 的項目產生預測。今天之前,基於先前 CreatePredictor API 加諸的限制,客戶產生的預測以 10 萬個唯一項目為限。部分使用案例中,有大量項目的客戶若非必須將模型侷限於項目子集,就是只能產生某些項目/類別特定的模型。這兩種方式都需要額外的資料準備,恐怕無法充分利用以大型資料集培訓深度學習演算法固有的優點。今天,我們針對每日及更高的資料頻率,將該限制提高至一百萬個唯一項目。此外,我們也將對目標時間序列資料集可支援的歷史觀測數量從一億增加為十億。如此可允許客戶在每個項目中包含最多一千筆觀測 (有一百萬個項目時),以便於產生模型時可提供充足的歷史資料。

現在,美國東部 (維吉尼亞北部、俄亥俄),美國西部 (奧勒岡),歐洲 (愛爾蘭、法蘭克福) 和亞太區域 (東京、新加坡、首爾、雪梨、孟買) 均提供此限額提高。使用 CreatePredictorCreateForecast API 時可以利用。如需詳細資訊,請瀏覽 Amazon Forecast 入門指南或更新後的服務限額

AWS 對 Internet Explorer 的支援將於 07/31/2022 結束。支援的瀏覽器包括 Chrome、Firefox、Edge 和 Safari。 進一步了解 »
