我正在尝试使用二进制数据构建产品推荐模型。
我的代码存在问题，我认为源于我传递函数data.matrix=as(df,"binaryRatingMatrix")
我的代码如下：
library(recommenderlab)
library(xlsx)
#change csv to original data when problem fixed
data=read.csv("New UBCF Data V2.csv",header=TRUE,row.names=1)
#remove rows where number of purchases is <10
df=data[rowSums(data[-1])>=10,]
data.matrix=as(df,"binaryRatingMatrix")
当我打印data.matrix时，它指出2x2 rating matrix of class 'binaryRatingMatrix' with 3 ratings
我期待比这更多的评分，我相信这就是我通过evaluationScheme传递这些数据时出错的原因。
鉴于str() df显示包含0或1（0/1）的867个变量的139个blind，我期望data.matrix包含远超过3个等级。< / p>
任何人都可以帮助解释这里发生了什么，就为什么这么多评级在强制df和＃34; binaryRatingMatrix＆＃34;之间消失了？
dput()的 df：

我已经弄明白了 - 出于某种原因，在读取我的csv和强制转换为“binaryRating Matrix”之间，我必须首先将df转换为矩阵。
library(recommenderlab)
library(xlsx)
#change csv to original data when problem fixed
data<-read.csv("New UBCF Data V2.csv",header=TRUE,row.names=1)
#remove rows where number of purchases is <10
df<-data[rowSums(data[-1])>=10,]
df<-as.matrix(df)
data.matrix<-as(df,"binaryRatingMatrix")
