Large Language Models (LLMs) have demonstrated surprising capabilities in solving a variety of general tasks, including answering complex questions, conducting extensive research, coding, and automating intricate processes.

However, the direct application of LLMs to many real-world use cases is often limited by their lack of company-specific knowledge. For example, even the most advanced LLMs today cannot match the deep expertise of investigators at PayPal, who possess detailed knowledge of complex policies and SOPs for Anti-Money Laundering and other compliance-related areas. Building on the limitations of Retrieval-Augmented Generation (RAG), we will explore and try out some of the fundamental approaches for training LLMs, including continuous pre-training, supervised fine-tuning, and reinforcement learning.

About Francesco Francesco Gelli is a Machine Learning Scientist at PayPal Global Analytics and Data Science in Singapore, where he supports the company’s enterprise priorities in the domains of Compliance and Privacy through the application of advanced AI and machine learning techniques.

Francesco earned his Doctor of Philosophy (PhD) in Computer Science from the National University of Singapore (NUS) and later joined PayPal, where he continuously develops innovative solutions that enhance data-driven decision-making and ensure the security and privacy of users.
