  # Model fine-tuned from roberta-large for topic classification of financial news (emphasis on Canadian news).
  
  ### Introduction
  This model was train on the topic column of financial_news_sentiment_mixte_with_phrasebank_75 dataset.
  The topic column was generated using a zero-shot classification model on 11 topics. 
  There was no manual reviews on the generated topics and therefore we should expect misclassifications in the dataset, 
  and therefore the trained model might reproduce the same errors.
