What purpose cutoff.csv used in the cc_net pipeline?

I am trying to add turkish language (tr) to cutoff.csv on rp_v1 branch.
There is few data on how the language score is calculated
How do we add custom language score on this csv?
Hi @kemalbastak
As far as I know, the CCNet pipeline does not support Turkish out of the box, but you can probably modify the pipeline to get it to support tr. We never went through that process, but to get there, I think you have to do the following steps:
- train your own reference wikipedia model (checkout the makefile and ccnet readme for that)
- collect the percentile statistics on the model distribution on the commoncrawl corpus
- add those statistics to the cutoff.csv
- run ccnet with turkish
I'd also recommend contacting the maintainers of the ccnet if there are issues related to that.
I hope this helps!
I have calculated for 2023-50 CC dump and used 'perplexity' score on that data.
percentiles = {f"%{i}": np.percentile(all_pp_values, i) for i in range(1, 101)}
Got closer values with the existing languages in the cutoff.csv.
Thanks for the answer
