How to generate the file X.trn.pnz

[shunshun-lala]

Hi, I'm wondering how you generate the file X.trn.npz, i.e. the instance TF-IDF feature matrix for the train set? Could you share your code about this process? Or is there any public code which have the same function?

Hi @shunshun-lala , this githbu repository is no actively maintained.

For the XMC datasets, please see https://github.com/amzn/pecos/tree/mainline/examples/spmm#data-statistics
That provides you the TF-IDF feature matrix stored in X.trn.npz and X.tst.npz.

The TF-IDF feature matrix is as same as the one from AttentionXML.
