Usage

Load the Model using transformers

from transformers import BertTokenizer, BertForSequenceClassification
import torch

model_name = "philipobiorah/bert-imdb-model"

# Load tokenizer and model
tokenizer = BertTokenizer.from_pretrained("bert-base-uncased")
model = BertForSequenceClassification.from_pretrained(model_name)

# Define function for sentiment prediction
def predict_sentiment(text):
    inputs = tokenizer(text, return_tensors="pt", truncation=True, padding=True, max_length=512)
    with torch.no_grad():
        logits = model(**inputs).logits
    return "Positive" if logits.argmax().item() == 1 else "Negative"

# Test the model
print(predict_sentiment("This movie was absolutely fantastic!"))
print(predict_sentiment("I really disliked this movie, it was terrible."))
