您好!
您提出的HawkesKT模型让人耳目一新,关于代码仓库中对AKT模型的复现我有一些小问题。
在您复现的代码中

question_seq只被embedding为diff_parm,但是在AKT的官方仓库中,question会被embedding为 (n_question+1, embed_l)。

期待您的回复。

根据论文 3.4 节的描述,question 确实只贡献 diff_param,只有一个 1 维的参数,不应该有 embedding。去看了一下官方仓库,他们的 question 变量应该对应论文中的 concept,即我们代码中的 skill,他们的 pid 变量才对应 question,比较歧义的命名方式。
