Text features generation and further operation

[ZeraPeng]

Thanks a lot for sharing your excellent work!
I have four questions:

1. I noticed there are two description files: "ntu60_llm.txt" and "ntu60.csv." I’ve confirmed that "ntu60_llm.txt" is from SMIE's work. Could you share the method or source for generating "ntu60.csv"? What is the purpose of this additional file?
2. In the "text_feats" dictionary, what do the labels "ad," "lb," and "md" signify for the npy files?
3. When I attempted to regenerate the encoded file "resources/text_feats/ntu60/clip-vit-b-16/ad_60.npy," the original data size was (60,768), but the encoded data with "clip-vit-b-16" had a size of (60,512). Could there be any mistakes on my end? Are there any post-processing steps, such as expanding dimensions by repeating data?
4. Could you provide the files for generating different splits?
   Thank you very much for your time!
