我想请教一下这个代码能否将BPR任务改成评分预测任务

@luanxian1 您好,RecSysDatasets 是一个数据集的 repo,不涉及具体的排序或评分预测任务。
在 RecBole 中,若您需要将 BPR 的排序任务改为评分预测任务,则需要按照 Label of data 将数据的标签设置为评分 (如 rating),并在模型中修改数据输入的 InputType 以及计算损失函数的函数 calculate_loss。
rating
InputType
calculate_loss
Sorry, something went wrong.

你好,感谢解答!我最近也有评分预测任务的需求,请问如果按照这种方式处理后,trainer中的label是truncate后的,还是没有truncate的呢?能不能直接给模型输入不truncate的评分,构造一个回归任务?
