AI的未來?你不能不認識的人工智慧與資料科學自動化技術—AutoML(7/10)
六、減少實作機器學習流程的時間
人們建立機器學習模型所花費的時間,與在人工監督下的機器學習相比通常太多,AutoML可以讓機器學習過程耗費更少的時間。隨著對大數據挖掘洞見(insight)的需求不斷增長,有些公司、組織正在利用複雜的自動化機器學習功能來擴大其預測能力。
機器學習過程通常包括資料前處理、模型選擇和評估,還有超參數優化調整。 這些會花費更多的時間來實施,並且需要大量的專業知識,而AutoML減少了執行某些繁瑣過程的麻煩。
現在,在大數據處理和預測分析正在迅速發展,特別是在大數據、雲端運算和基於物聯網(IoT)的服務數量和複雜性方面。根據 [11] 此調查,在2019年,投資於大數據和AI的公司、組織數量已從2018年的27%激增至33.9%。這表明基於大數據的技術和分析只會越來越多,這也是AutoML為何會成為公司在2020年處理大量資料的主要重點之一。

[美股業績幾分鐘][星巴克靠加價,可以頂到幾耐?我估好耐]
原文: (https://reut.rs/2V3WrOE) 'Anemic' traffic raises doubts over Starbucks sales gains
圖就星巴克官網 (http://bit.ly/2GGp1vD)
故事好簡單,星巴克個業績其實勝過預期,股價一度創新高,但之後冇乜力。分析員開始擔心,之後點算?(當然亦可能只係因為股價已經唔平所以冇力)
點解會擔心之後點算?就係正如路透社的文講,'Anemic' traffic。當然唔好標題黨,我開頭心諗,少咗人去舖又如何?個個用App落外賣啦。然後再諗下:其實用App都係要去間舖度嘛!況且,未有咁高科技數住人頭下話?
路透社題講嘅traffic,係指交易數目,單數(唔係單雙數的單數,咁當然單數可以係單數,亦可以係雙數)
正如舊文講,零售或者工業股嘅嘢,不外乎就係 量X價,volume X ASP(http://bit.ly/2GJ5Ykp 希望顧客買多啲,同埋加到價).咁快餐店咖啡店嘅嘢,都不外乎係 單價X單數。幾多張單X一張單幾錢。係咁簡單。
順手講多筆,本人唔係睇零售股(少好多著數的說,睇莎莎就話過年醒PACK化妝品畀你,睇李寧醒對鞋比你,但睇恒生總冇可能醒幾千蚊比你)。但有個概念大家都要知,SSSG,Same-store sales growth,同店銷售。有時又叫Comparable Store Sales Growth,CSSG,口頭就叫Comps Store Sales。
原理好簡單,就係只計啲「可比」嘅門店。例如星巴克嘅可比門店,係計開咗13個月或以上嘅。點解要咁?因為你靠不停開分店,當然實谷到個sales。唔係話唔得唔係話啲錢臭,但一來開新店有極限,二來要成本。三來,都想分開兩樣嘢睇。我會想知你收入增長,幾多係嚟自開新店,幾多係舊店做得好帶嚟。
好啦,星巴克嘅問題,似乎就出現在呢度。你去份業績睇下(http://bit.ly/2GGp1vD),唔使睇晒,搵有Comparable Store Sales Growth嘅表就科勞到。
可以見到,差不多所有地區嘅Comparable Store Sales Growth,差不多都係靠Change in Ticket,單價,去推動。至於Change in Transactions,單數增長,係近乎零嘅。即係話,冇多人幫襯咗,冇多咗單。但只係每張單大家洗多咗錢。
再細睇,真係咁喎。美洲(美國加拿大啦,墨西哥人唔飲的,飲Tequila或者 Corona),平均單價升4%,單數冇增長。中國及亞太區,平均單價升2%,單數冇增長。EMEA (歐洲中東非洲,又學多個術語了,讀M-mia仲型)呢,平均單價升2%,單數又係冇增長。
更加令人擔心嘅係,中國(同美國一樣,要另外列出嚟喎,認真畀面)。平均單價升4%,但單數,仲要跌,驚驚。當然其中一個原因係面對對手,瑞幸咖啡。間嘢而家上市添,又有人同佢癲,又有錢繼續燒。
咁有啲分析員就有啲擔心咯,你加價可以加幾多呢?況且,對手上手有錢燒喎。
小弟認為,其實都係睇你睇兩個月定睇兩年。短期,股價都新高啦,就一定係對壞消息敏感啲,對好消息冇乜反應。但加價?我就覺得幾有信心。本人唔飲星巴克咖啡(但我輕易做到金會員,日日飲茶咪得),但照我理解,其實多數人都唔係好理啲咖啡係點,係型,係一種生活態度嘛,係上瘾嘛。其實同煙仔一樣,應該幾有加價空間的。當然煙仔係幾間大廠合謀,咖啡都仲要問下對手係咪一齊加嘅。
另外,瑞幸云云,唔外國都要講,算吧啦。我冇飲過啲咖啡,但根本唔係重點。聽講話賣得平嘛,但賣一杯蝕一杯。好彩而家個市都好,仲上到市仲有人同佢癲,但燒得幾耐?星巴克大企業,要燒錢我估你死佢都未死。一時可能受壓,但到瑞幸執埋笠,在中國更加無人可以挑戰星巴克啦(不過,阿爺會唔會想扶持本土企業唔想鬼佬獨大呢,呢啲政治嘢就好難量化了,自己估)
另外,都未寫,其實唔係好識寫。但其實星巴克差不多係用mobile payment 最成功嘅公司,係喎,成功過Apple Pay Google Pay。佢在美國本土嘅用戶多過Apple Pay,更加係Google Pay嘅幾倍.但星巴克by definition 只能在佢嘅店用,個數都可以咁勁,係有啲嘢的。唔知公司點運用定乜啦,斷估唔會賣你啲data(唔好成日以為自己好值錢啦),但呢個優勢都幾值錢。
