关于SGNN在Movielens上运行欠拟合,请问如何解决? #2
Comments
你好,为什么认为出现了欠拟合呢,具体是什么现象? |
现象: 分析与判断: |
解决方式: 在其他数据集上为什么没有暴露出这个问题? |
embeddig纬度和网络层数都是对学习率和正则系数敏感的超参,如果你换emb_dim的话你得对模型关于学习率和正则系数重新调参(当然,为了公平比较,SGNN和baselines都要调),我的代码里有调参工具,main.py中24行换成tuning_method = ['tuning', 'fine_tuning', 'cross_tuning', 'coarse_tuning', 'test'][0]。 |
按照本仓库中的参数,SGNN在Movielens上运行出现欠拟合情况,请问为什么出现的原因是什么呢?如何解决比较好?调整学习率?
