bsingh/roberta_goEmotion

This model is trained for GoEmotions dataset which contains labeled 58k Reddit comments with 28 emotions

• admiration, amusement, anger, annoyance, approval, caring, confusion, curiosity, desire, disappointment, disapproval, disgust, embarrassment, excitement, fear, gratitude, grief, joy, love, nervousness, optimism, pride, realization, relief, remorse, sadness, surprise + neutral

Training details:

• The training script is provided here: https://github.com/bsinghpratap/roberta_train_goEmotion
• Please feel free to start an issue in the repo if you have trouble running the model and I would try to respond as soon as possible.
• The model works well on most of the emotions except: 'desire', 'disgust', 'embarrassment', 'excitement', 'fear', 'grief', 'nervousness', 'pride', 'relief', 'remorse', 'surprise']
• I'll try to fine-tune the model further and update here if RoBERTa achieves a better performance.
• Each text datapoint can have more than 1 label. Most of the training set had 1 label: Counter({1: 36308, 2: 6541, 3: 532, 4: 28, 5: 1}). So currently I just used the first label for each of the datapoint. Not ideal but it does a decent job.
