Orthogonal Model of Emotions (OME)

This model is a fine-tuned version of distilbert/distilroberta-base on the OME v5.2 dataset.

It achieves the following results on the evaluation set:

• Loss: 0.1073
• Accuracy: 0.9803

Model description

This latest variation of the OME is a text classifier based on distilroberta and fine-tuned with 26 categories using Transfer Learning for classifying emotion in English language examples in a curated dataset deriving emotional clusters using dimensions of Subjectivity, Relativity, and Generativity. Additional dimensions of Clarity, now simpler with three levels, and Compassion, using rate of change to linearize the data, were used to map seven population clusters of ontological experiences categorized as Trust or Love, Happiness or Pleasure, Jealousy or Envy, Shame or Guilt, Anger or Disgust, Fear or Anxiety, and Sadness or Trauma. Edge cases, neutrality, and simple sentiments, such as positive and negative, are also used as null cases in classification theorized by OME.

Intended uses & limitations

The Orthogonal Model of Emotions (OME) was crafted and built with the purpose of representing the totality of emotional expression as represented in English. OME is synthetic compassion, a context for empathy based on predicting the closest possible match based on natural language processing and statistical validation.
