hi,

Thanks for your sharing.
i'm trying to apply your code to my toy recommendation project. During it, I've developed into 3 concerns:

1. we have 300k Chinese titles dataset, and after several training epochs of autoencoder, the loss plateaus at 19k+, which is simply too high. Do you have any idea how to fine tune the autoencoder?
2. I trained RNN with 50k samples, again, after several epochs, the auc goes back and forth around 0.53~0.54, Is there any way to fine tune the model?
3. Is it a good idea to just fetch the trained user embedding, do the dot product with item embedding to recommend? thanks

近期打算使用Embedding based News Recommendation，在GitHub找到了你写的开源代码，代码和逻辑都挺清晰的，但整个工程没有完成，是否能够和博主一块把剩余的开发完整呢，我的wx：1204834968

I don't understand why rnn input file has no user_id，train_RS not finished yet?Or have some other consideration？

Hi ,I am a little confused about word_hashing_file = r'Y:\BingNews\Zhongxia\my\articles_wordhashing_3w.obj'.
Dose the word_hashing_file contain some context or is just empty? I don't have this file. Should I create one or the project will create this file automatically when it compiles?

hi
you have done a great work . can you please email or share the link of original complete dataset.

I will appreciate.

Thanks

hi,dear
what's the meaning of the sentence ?
data/RS/train.txt: each line is a training instance, in the form of user_history \t target_item_id \t label. user_history is a sequence of item_id, splited by space.

user_history is only user clicks ?
target_item_id is the user last click ?
and if the last click is real click , the label is 1, else 0,

could u pls help me ?
thx

hi,author
I have some questions about the training data.
in train.txt,What each line represents
and in article.txt,The first line and the second line are repeated eighft times.？
