roberta-large-emopillars-contextless-goemotions

This model is a fine-tuned version of roberta-large-emopillars-contextless on the GoEmotions dataset. The base model was trained on EmoPillars' context-less subset.

Model description

The model is a multi-label classifier over 28 emotional classes for a context-less scenario. It detects emotions in the entire input (including context if provided).

How to use

Here is how to use this model:

>>> import torch
>>> from transformers import pipeline
>>> model_name = "roberta-large-emopillars-contextless-goemotions"
>>> threshold = 0.36
>>> 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"
>>> ]
>>> label_to_emotion = dict(zip(list(range(len(emotions))), emotions))
>>> device = torch.device("cuda" if torch.cuda.is_available() else "CPU")
>>> pipe = pipeline("text-classification", model=model_name, truncation=True,
>>>                 return_all_scores=True, device=-1 if device.type=="cpu" else 0)
>>> # input in a format f"{text}"
>>> utterances = [
>>>     "Ok is it just me or is anyone else getting goosebumps too???",
>>>     "Don’t know what to do",
>>>     "I’m glad you had a great time here! Wishing you safe travels!"
>>> ]
>>> outcome = pipe(utterances)
>>> dominant_classes = [
>>>     [prediction for prediction in example if prediction['score'] >= threshold]
>>>     for example in outcome
>>> ]
>>> for example in dominant_classes:
>>>     print(", ".join([
>>>         "%s: %.2lf" % (label_to_emotion[int(prediction['label'])], prediction['score']) 
>>>         for prediction in sorted(example, key=lambda x: x['score'], reverse=True)
>>>     ]))
