The Orthogonal Model of Emoji (OMEmoji)

Around here, better known as: distilroberta-base-omemoji-v0.1! Note well, this isn't a text-replacement emoji prediction tool.

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

It achieves the following results on the evaluation set:

• Loss: 0.1496
• Accuracy: 0.9549

Model description

This latest variant of the OME is a text classifier based on distilroberta and fine-tuned with 10 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. An additional dimension of Clarity was removed, while still Compassion, using rate of change to linearize the data, was used to map seven population clusters of ontological experiences categorized and represented by emojis 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

While the Orthogonal Model of Emotions (OME) was crafted and built with the purpose of representing the totality of emotional expression as represented in English, this is beta software, so use at your own risk!
