ROSA :: Emotional Sensitivity

“To feel is to know; to know is to bloom.” ·Willinton

ROSA is a fine-tuned Transformer model based on bert-base-uncased, trained on the GoEmotions dataset to classify 28 nuanced human emotions (plus neutral).
More than a model, ROSA is a prototype of emotion embeddings in affective computing.

✨ Highlights

• Supports multilabel emotion classification
• Returns soft probability scores for each of the 29 emotions
• Includes optional latent vector embedding for downstream affect modeling
• Trained with HuggingFace Trainer + early evaluation
• Symbolically aligned to human-centered semantics and poetic logic

🌸 Emotion Set

["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"]

🔮 Usage

from transformers import BertTokenizer
from model.emotion_model import Rosa
import torch

tokenizer = BertTokenizer.from_pretrained("bert-base-uncased")
model = Rosa(num_emotions=29)
model.load_state_dict(torch.load("rosa.pt"))
model.eval()

text = "My heart is filled with longing and beauty."
inputs = tokenizer(text, return_tensors="pt", padding=True, truncation=True)

with torch.no_grad():
    outputs = model(**inputs)
    probs = torch.sigmoid(outputs["logits"]).squeeze()

# Result: list of probabilities for each emotion
