使用MovieLens数据集实现了基于Auto Encoder(AE), Variational Auto Encoder(VAE), BERT的深度学习电影推荐系统
MovieLens1M 基于深度学习的电影推荐系统
使用MovieLens1M数据集(data can be downloaded from https://grouplens.org/datasets/movielens/) ,实现了Auto Encoder (AE), Variational Auto Encoder (VAE), BERT提取电影名特征3种方法,对评分矩阵进行填补,继而对用户做出推荐。
代码建议在Google Colab环境下运行,代码中的目录请根据自己的实际目录进行修改。
