Python Usage Example

from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch

model_id = "harry2708/disaster-bert"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForSequenceClassification.from_pretrained(model_id)

text = "Flood situation in Assam improves marginally as river water recedes"
inputs = tokenizer(text, return_tensors="pt", truncation=True, max_length=128)

with torch.no_grad():
    outputs = model(**inputs)
    probs = torch.softmax(outputs.logits, dim=1).squeeze(0)
    top_idx = torch.argmax(probs).item()
    confidence = probs[top_idx].item()

predicted_label = model.config.id2label[top_idx]
print(f"Predicted Disaster: {predicted_label} ({confidence * 100:.2f}% Confidence)")
