我正在尝试使用二进制数据构建产品推荐模型。
我的代码有一个问题，我认为这源于我传递函数时源数据的结构如何变化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级，我相信这就是我在通过评估方案传递这些数据时收到错误的原因。
鉴于显示 867 个变量中str()的df139 个 obs 包含零或一 (0 / 1)，我期望 data.matrix 包含远远超过 3 个评级。
任何人都可以帮助解释这里发生了什么，为什么这么多评级在强制df到“binaryRatingMatrix”之间消失？
dput()以下df：
