This model should not be used for generating harmful content
Not suitable for tasks requiring factual accuracy about movies or real-world events
Not designed for multilingual sentiment analysis

Bias, Risks, and Limitations

The model may exhibit biases present in the IMDB dataset
Performance may vary on reviews from different domains (non-movie content)
As a LoRA adapter, it maintains the base model's limitations
May struggle with sarcasm, irony, or complex emotional nuances

Recommendations

Users should be aware that this model is specifically trained for movie review sentiment and may not generalize well to other text types. Consider the dataset's demographic and linguistic biases when applying to new domains.

How to Get Started with the Model

python

from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline
from peft import PeftModel, PeftConfig

# Load the model
model_id = "keyegon2024/falcon-lora-imdb"
peft_config = PeftConfig.from_pretrained(model_id)

# Load base model
base_model = AutoModelForCausalLM.from_pretrained(
    peft_config.base_model_name_or_path,  # tiiuae/falcon-rw-1b
    trust_remote_code=True,
    device_map="auto"
)

# Load LoRA adapter
model = PeftModel.from_pretrained(base_model, model_id)
model.eval()

# Load tokenizer
tokenizer = AutoTokenizer.from_pretrained(
    peft_config.base_model_name_or_path, 
    trust_remote_code=True
)
tokenizer.pad_token = tokenizer.eos_token

# Create inference pipeline
pipe = pipeline(
    "text-generation",
    model=model,
    tokenizer=tokenizer,
    max_new_tokens=100,
    do_sample=True,
    temperature=0.8,
    top_k=50,
    top_p=0.95
)

# Example usage
prompt = "The movie was absolutely wonderful because"
result = pipe(prompt)
print(result[0]["generated_text"])
