I built an end-to-end LLM pipeline in PyTorch focused on data cleaning, supervised fine-tuning, and reinforcement learning from human feedback. This involved structuring raw textual data, formatting prompts and responses, and crafting supervised learning datasets for AI model training. The work also included workflow design for various training stages and adaptation methods. • Processed and cleaned raw textual data for model training. • Generated prompt-response pairs for supervised fine-tuning. • Supported RLHF/DPO stages with prompt curation and quality checking. • Facilitated effective training dataset creation for Transformer-based models.

I contributed to the creation of Chinese medical QA training data for an LLM fine-tuning project. I constructed and supervised question-answer pairs, including teacher-supervised and distractor-augmented samples, to enhance the model's language understanding and robustness. My work enabled efficient data normalization, prompt formatting, and evaluation of model outputs for academic research. • Designed and generated 1,199 teacher-supervised QA samples. • Created 1,195 distractor-augmented instances to improve model robustness. • Implemented evaluation pipelines for retrieval and hallucination analysis. • Assisted in dataset preparation and quality assurance for LLM training.
