【天池竞赛系列】阿里移动推荐算法思路解析

發布時間：2023/12/19 综合教程 22 生活家

生活随笔收集整理的這篇文章主要介紹了【天池竞赛系列】阿里移动推荐算法思路解析小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

賽題地址：http://tianchi.aliyun.com/competition/information.htm?raceId=1

登錄就可以下載數據

從4月到7月，學習了非常多也收獲了非常多

題目就不多說了。一句話表達就是依據過去一個月的行為預測14年12月19號的購買情況。

看題目貌似推薦算法。自然就有隊伍想到用協同過濾什么的。當然效果不好。

首先是特征的問題，然后是這是基于行為的相似，不太類似用戶和商品類似的ItemCF。UserCF，還有非常多其它的原因。比方我買過一部手機，難道還要推薦我再買其它類似的手機嗎，當然這個比喻不太恰當。

最后還是歸為2分類問題，當然從多分類也能夠解決這個題目。

算法問題：既然二分類就要用到分類算法。從第一賽季和第二賽的實戰情況來看，個人比較推薦的算法是C45，隨機深林。GBDT。LR，數據量大的時候也能夠增加并行的神經網絡，之前天貓推薦算法第一名就是使用了自己并行化的神經網絡。

訓練集測試集構建問題：然后怎么建模呢，怎樣選取訓練集測試集。

既然是預測一天的購買情況，那我們一樣能夠把18號當作未知。來構建模型預測18號的購買情況。

那么我們能夠把18號的購買與否來給18號前的數據打標簽。形成UIR對（user,item,result）

在第一賽季時間充足的情況下事實上還能夠弄個訓練集和驗證集。也就是用17號給之前的數據打標簽做訓練集，18號給之前的數據打標簽做驗證集。19號前的數據做線上測試集（19號的答案比賽結束后也沒有給出）

數據不平衡問題：第一賽季的數據正負樣本比例我忘了，第二賽季的好像是1:300來著，也就是說必須得採樣了，詳細採樣比例還得自己做實驗，在第二賽季我們的採樣比例是1:10——1:14之間。

數據預處理問題：第一賽季數據量僅僅有1000W左右。預處理效果一般般。第二賽季效果就出來了，數據量58E。

由于有可能有異經常使用戶的出現，比方一天點擊上萬次。或者點擊非常多從不購買等問題。一般從兩個方面來考慮。要么過濾異經常使用戶的全部數據，要么僅僅取近期幾天（3-7天都能夠）出現過的用戶和商品（這個思路是決賽第七名隊伍的）。

特征問題：原始數據有例如以下字段。用戶ID，商品ID，商品類別ID，時間（精確到小時），地理位置。行為（1234）

首先我們能夠劃分特征類別。比方分為用戶—商品類特征，用戶—商品類別類特征，商品—商品類別特征，商品類特征，用戶類特征，商品類別類特征，交叉特征（各種特征進行有意義的交叉乘除）等幾個方面。

另外一定要做特征選擇，我採訪過一些top50選手，他們特征基本都在100-400之間。就我們隊傻傻的搞了800，真是哭瞎在廁所。

特征劃分粒度問題：能夠劃分為月，周，天，小時。當然小時取值24個多了點，能夠進行切片，在做過初步數據統計之后會發現購買時間熱段和冷段，來適當調整時間片長度。

模型融合問題：多模型融合效果會較單模型有提升。當然特征夠好的情況下提升不太明顯。融合方法通常是多次不同比例不同採樣不同參數不同模型不同權值融合。

還有一個思路是做級聯，也就是先用訓練預測數據都超級快的LR，把正負樣本比例調到1:1或者1:2之類的。為啥比例是這樣呢，能夠先自己思考下。由于在這里比例會將80%未購買的樣本過濾掉（實際上90%都有可能）并且過濾掉的未購買樣本實際上也確實是沒購買的。

這樣有助于提高后面GBDT等決策樹模型的精度。還有個思路就是把其它模型得到的概率作為特征，這點比較重要。

補充點重要的東西：不要盲目迷信哪種算法吊什么的。沒有最吊的算法。僅僅有更吊的思路。思路決定一切，這一切都反應在特征和一些細節上。我們隊踩過的一些坑大概就是沒用MR，也不會MR，沒做預處理，沒做特征選擇。沒設計時間切片的特征，倒是設計了1000+無用的特征，結果GBDT僅僅支持800，就隨便扔了800個進去，結果可想而知。

我們隊的成績在第一賽季是10.09%分

第二賽季是7.7%分

非常遺憾沒進前50，最后奉上3位決賽前10名大神的特征，感謝他們提供的特征方案。假設這三位大神看到了介意的話跟我說聲。

特征版本號0（我們隊的特征，沒啥參考性。反面教材還是能夠的）：

特征版本號1：

下面是阿里移動推薦算法用到的特征、如無特別說明。則每項特征都是以1、2、4、7、14、21、28作為周期分別計算。

且在計算時間特征時、都是以小時為單位。

一、用戶-商品特征

1、用戶對商品點擊、收藏、加購物車、購買的近期時間。

2、用戶對商品點擊、收藏、加購物車、購買的次數

3、按時間分段，且同樣粒度的時間段之間不重疊，分別統計用戶對商品的點擊、收藏、加購物車、購買的次數，分段粒度分別為6小時、12小時、1天、3天、7天、14天。因為該特征分數提升比較小，實際并沒有計算全部分段。比方6小時為粒度的僅僅取了前兩段

ps：不重疊分段的特征沒有按周期分別計算，下同

二、用戶-商品、用戶-類別組合特征

1、用戶對除去該商品的同類其它商品的點擊、收藏、加購物車、購買次數。

2、按時間分段且同樣粒度的時間段之間不重疊對特征1進行計算。類似用戶-商品特征3

3、用戶對該商品的近期點擊、收藏、加購物車、購買時間減去同類其它商品的近期點擊、收藏、加購物車、購買時間（點擊-點擊...）

4、用戶對該商品的近期點擊、收藏、加購物車、購買時間減去同類其它商品的近期購買時間

5、用戶對商品的點擊量減去用戶對同類其他商品的平均點擊量

三、用戶特征（子集和全集分別計算該類特征。其它大類特征僅僅在商品子集計算）

1、用戶近期點擊、收藏、加購物車、購買時間

2、用戶點擊、收藏、加購物車、購買量

3、用戶轉化率即用戶購買量分別除以用戶點擊、收藏、加購物車這三類行為數

4、用戶點擊、收藏、加購物車、購買量在28天里的均值方差（不按周期計算）

四、商品特征

1、商品被點擊、收藏、加購物車、購買量

2、商品被購買轉化率

3、商品被點擊、收藏、加購物車、購買量在28天里的均值方差

五、類別特征

1、該類商品被點擊、收藏、加購物車、購買量

2、該類商品轉化率

六、交叉特征

1、用戶對商品近期點擊、收藏、加購物車、購買時間減去該用戶近期點擊、收藏、加購物車、購買時間

2、用戶對商品近期點擊、收藏、加購物車、購買時間減去該用戶購買時間

3、用戶對商品點擊、收藏、加購物車、購買量減去用戶平均點擊、收藏、加購物車、購買量

4、用戶對商品點擊、收藏、加購物車、購買量減去商品平均被點擊、收藏、加購物車、購買量

5、用戶對商品點擊、收藏、加購物車、購買量除以用戶點擊、收藏、加購物車、購買量

6、用戶對商品點擊、收藏、加購物車、購買量除以用戶對該類其他商品點擊、收藏、加購物車、購買量

7、用戶對商品點擊、收藏、加購物車、購買量除以該商品被點擊、收藏、加購物車、購買量

8、商品被點擊、收藏、加購物車、購買量除以該類商品被點擊、收藏、加購物車、購買量

七、雙十二處理

在計算商品特征和用戶特征時刪除雙十二數據，在計算時間周期等時，雙12后面的時間前移一天填補雙十二的空缺。

但在計算交叉特征時。假設須要計算上述特征仍然保留雙十二數據。

八、滑動窗體（效果微小）

曾經28天為歷史數據計算特征，后一天的購買情況打標簽，如用11月18號至12月15號數據計算特征，以12月16號購買情況打標簽。

然后窗體依次滑動一天，如此一共得到4個數據集，用前三個數據集作為訓練集。最后一個數據集作為測試集。

九、前期樣本過濾及抽樣

僅僅保留前兩天有操作的的樣本、然后正樣本過採樣到4倍。負樣本隨機抽樣，抽樣后正負樣本比約為1：8
