LLaMA2 Fine-Tuned on not Engaging with Hate Speech

Model Description

This model is a fine-tuned version of meta-llama/Llama-2-13b-chat-hf on a hate speech dataset using the PEFT approach, to prevent the model from exacerbating hate discourse.

Intended Uses & Limitations

This model is intended for research purposes in conversational applications to stop hate speech generation.

Bias, Risks, and Limitations

Biases: The model may carry biases present in the training data.
False Positives/Negatives: It's not perfect and may continue some hate speech conversations.
Domain Specificity: Performance may vary across different domains.

How to Get Started with the Model

Use the code below to get started with the model.

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

# Load the model
config = PeftConfig.from_pretrained("irlab-udc/LLaMA2-13b-Stop-Hate")
base_model = AutoModelForCausalLM.from_pretrained("meta-llama/Llama-2-13b-chat-hf", config=config)
model = PeftModel.from_pretrained(base_model, "irlab-udc/LLaMA2-13b-Stop-Hate")
tokenizer = AutoTokenizer.from_pretrained("irlab-udc/LLaMA2-13b-Stop-Hate")

# Test the model
chatbot = pipeline(task="conversational", model=model, tokenizer=tokenizer)
conversation = Conversation("Your input text here")
conversation = chatbot(conversation)
result = conversation.messages[-1]["content"]

  abstractNote={Hate speech represents a pervasive and detrimental form of online discourse, often manifested through an array of slurs, from hateful tweets to defamatory posts. As such speech proliferates, it connects people globally and poses significant social, psychological, and occasionally physical threats to targeted individuals and communities. Current computational linguistic approaches for tackling this phenomenon rely on labelled social media datasets for training. For unifying efforts, our study advances in the critical need for a comprehensive meta-collection, advocating for an extensive dataset to help counteract this problem effectively. We scrutinized over 60 datasets, selectively integrating those pertinent into MetaHate. This paper offers a detailed examination of existing collections, highlighting their strengths and limitations. Our findings contribute to a deeper understanding of the existing datasets, paving the way for training more robust and adaptable models. These enhanced models are essential for effectively combating the dynamic and complex nature of hate speech in the digital realm.},
