In this new study, the primary goal was to fine-tune TinyLLAMA using Proximal Policy Optimization (PPO) techniques combined with Reinforcement Learning from Human Feedback (RLHF). The objective is to refine the model's ability to avoid generating harmful, offensive, or toxic language while preserving meaningful content generation.

Highlights of the Study:

• Fine-Tuning Objective: Implement RLHF to make TinyLLAMA more sensitive to language safety, focusing on removing toxic and offensive elements from generated outputs.
• Model Configuration: Leveraging PPO, a reinforcement learning technique, to optimize TinyLLAMA’s reward function toward producing non-offensive language.
• Evaluation: Summarization tasks were used to test the model's behavior in dialogue scenarios, and the fine-tuned TinyLLAMA demonstrated a significant reduction in offensive language while retaining coherence in its outputs.

The ILENIA project is part of Spain's Strategic Project for Economic Recovery and Transformation (PERTE), which focuses on developing multilingual resources for the New Language Economy (NEL). This initiative supports the use of Spanish and other official languages to drive economic growth and international competitiveness in areas like AI, translation, and education.

As part of this effort, we evaluate LLMs from the Aguila7B and Latxa projects, which are designed for text and speech processing tasks. These evaluations focus on the models' performance, ensuring they align with societal and technological needs, particularly in multilingual and cross-lingual contexts.

Key Aspects:

• Multilingualism and Cross-lingual Transfer: The models are evaluated for their ability to handle text and speech data across multiple languages.
• Project Timeline: ILENIA spans 36 months and is led by the Barcelona Supercomputing Center (BSC-CNS).
• Resource Optimization: The fine-tuning of LLMs ensures efficient model generation, optimizing costs and computational resources.

In the fast-evolving world of natural language processing (NLP), leveraging pre-trained language models has become crucial for improving performance across various tasks. 🌟 Among these, the T5 family of models stands out for its versatility and effectiveness in handling a range of language tasks. This study delves into the evaluation and analysis of pre-trained T5 models, focusing on how prompt engineering and few-shot examples can be used to fine-tune these models. 🔍

The T5 family, including models like T5-Base, T5-Large, and FLAN-T5, has shown impressive capabilities in text generation, question answering, and translation. Yet, there is always room for optimization. Fine-tuning these models using prompt engineering—designing and structuring input prompts—along with few-shot learning, offers a powerful method to enhance their performance without extensive retraining. ⚙️

In this work, we thoroughly evaluate different T5 models, exploring how various prompt engineering techniques and few-shot learning setups affect their performance. Our goal is to uncover best practices for fine-tuning pre-trained models to excel in real-world applications. By analyzing the strengths and limitations of each model under different prompt conditions, this study aims to provide valuable insights into optimizing T5-based LLMs for diverse NLP tasks. 📈
