Sustainable AI Alignment for Personal and Small-Scale Applications: Leveraging RLHF and Pretraining for Domain-Specific Language Models

This thesis seeks to explore the use of Reinforcement Learning from Human Feedback (RLHF) and pretraining techniques to fine-tune small language models for domain-specific applications. Focusing on data from health, manufacturing, and space sectors, this research will offer insights into how sustainable AI alignment can be achieved for specific uses without the need for large-scale, computationally expensive models.
