# distilbert_classifier_newsgroups
This model is a fine-tuned version of [distilbert-base-uncased](https://huggingface.co/distilbert-base-uncased) on [20Newsgroups](http://qwone.com/~jason/20Newsgroups/) dataset.
It achieves the following results on the evaluation set:
## Model description
We have fine-tuned the distilbert-base-uncased to classify news in 20 main topics based on the labeled dataset [20Newsgroups](http://qwone.com/~jason/20Newsgroups/).
## Training and evaluation data
The 20 newsgroups dataset comprises around 18000 newsgroups posts on 20 topics split in two subsets: one for training (or development) and
the other one for testing (or for performance evaluation).
The split between the train and test set is based upon a messages posted before and after a specific date.
These are the 20 topics we fine-tuned the model on:
'alt.atheism',
'comp.graphics',
'comp.os.ms-windows.misc',
'comp.sys.ibm.pc.hardware',
'comp.sys.mac.hardware',
'comp.windows.x',
'misc.forsale',
'rec.autos',
'rec.motorcycles',
'rec.sport.baseball',
'rec.sport.hockey',
'sci.crypt',
'sci.electronics',
'sci.med',
'sci.space',
'soc.religion.christian',
'talk.politics.guns',
'talk.politics.mideast',
'talk.politics.misc',
'talk.religion.misc'
