Orthogonal Model of Emotions (OME)

This model is a fine-tuned version of distilbert/distilroberta-base trained on the OME v4.2 dataset.

It achieves the following results on the evaluation set:

• Loss: 0.0046
• Accuracy: 0.9966

Model description

This latest variation of the OME is a text classifier based on distilroberta and fine tuned with 47 categories for classifying emotion in English language examples from a curated dataset deriving emotional clusters using dimensions of Subjectivity, Relativity, and Generativity. Additional dimensions of Clarity and Acceptance were used to map seven population clusters of ontological experiences categorized as Trust or Love, Happiness or Pleasure, Sadness or Trauma, Anger or Disgust, Fear or Anxiety, Guilt or Shame, and Jealousy or Envy.
