Usage

Load Model

from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch

model_name = "AzrilFahmiardi/sdd-sentiment-general"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForSequenceClassification.from_pretrained(model_name)

device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
model = model.to(device)

Inference

def analyze_sentiment(text: str) -> dict:
    inputs = tokenizer(text, return_tensors="pt", truncation=True, max_length=256).to(device)
    
    with torch.no_grad():
        outputs = model(**inputs)
        logits = outputs.logits
    
    probabilities = torch.softmax(logits, dim=-1)[0].cpu()
    predicted_class = logits.argmax(-1).item()
    predicted_label = model.config.id2label[predicted_class]
    confidence = probabilities[predicted_class].item()
    
    return {
        "sentiment": predicted_label,
        "confidence": confidence
    }

# Example
text = "Pemerintah berhasil menurunkan inflasi, ekonomi tumbuh positif tahun ini."
result = analyze_sentiment(text)
print(f"Sentiment: {result['sentiment']} ({result['confidence']:.2%})")

Output Format

{
  "sentiment": "positif",
  "confidence": 0.9234
}
