  # GPT-Neo 125M pre-trained on cleaned Dutch mC4 🇳🇱
  
  A GPT-Neo small model (125M paramters) trained from scratch on Dutch, with perplexity 20.9 on cleaned Dutch mC4.
  
  ## How To Use
  
  You can use this GPT-Neo model directly with a pipeline for text generation.
  
  ```python
  MODEL_DIR='yhavinga/gpt-neo-125M-dutch'
  from transformers import pipeline, GPT2Tokenizer, GPTNeoForCausalLM
  tokenizer = GPT2Tokenizer.from_pretrained(MODEL_DIR)
  model = GPTNeoForCausalLM.from_pretrained(MODEL_DIR)
  generator = pipeline('text-generation', model, tokenizer=tokenizer)
  
  generated_text = generator('Wetenschappers verbonden aan de Katholieke Universiteit', max_length=256, do_sample=True, top_k=50, top_p=0.95, temperature=0.7, no_repeat_ngram_size=2))
  ```

  Het DNA van een mens is niet alleen informatiedrager, maar ook een bouwstof voor het DNA. Het wordt gevonden in de genen van een cel. Als er op een cel een cel"*
  
  ## Tokenizer
  
  * BPE tokenizer trained from scratch for Dutch on mC4 nl cleaned with scripts from the Huggingface
    Transformers [Flax examples](https://github.com/huggingface/transformers/tree/master/examples/flax/language-modeling).
  
  ## Dataset
  
  This model was trained on of the `full` configuration (33B tokens) of
  [cleaned Dutch mC4](https://huggingface.co/datasets/yhavinga/mc4_nl_cleaned),
  which is the original mC4, except
  
    * Documents that contained words from a selection of the Dutch and English [List of Dirty Naught Obscene and Otherwise Bad Words](https://github.com/LDNOOBW/List-of-Dirty-Naughty-Obscene-and-Otherwise-Bad-Words) are removed
    * Sentences with less than 3 words are removed
    * Sentences with a word of more than 1000 characters are removed
    * Documents with less than 5 sentences are removed
    * Documents with "javascript", "lorum ipsum", "terms of use", "privacy policy", "cookie policy", "uses cookies",
      "use of cookies", "use cookies", "elementen ontbreken", "deze printversie" are removed.
   
  ## Models
  
  TL;DR: [yhavinga/gpt2-medium-dutch](https://huggingface.co/yhavinga/gpt2-medium-dutch) is the best model.
  
  * The models with `a`/`b` in the step-column have been trained to step `a` of a total of `b` steps.
