Article Introduction：2024 is a year of rapid development for large language models (LLM). In the training of LLM, alignment methods are an important technical means, including supervised fine-tuning (SFT) and reinforcement learning with human feedback that relies on human preferences (RLHF). These methods have played a crucial role in the development of LLM, but alignment methods require a large amount of manually annotated data. Faced with this challenge, fine-tuning has become a vibrant area of ​​research, with researchers actively working to develop methods that can effectively exploit human data. Therefore, the development of alignment methods will promote further breakthroughs in LLM technology. The University of California recently conducted a study introducing a new technology called SPIN (SelfPlayfInetuNing). S

Article Introduction：LoRA (Low-RankAdaptation) is a popular technique designed to fine-tune large language models (LLM). This technology was originally proposed by Microsoft researchers and included in the paper "LORA: LOW-RANKADAPTATION OFLARGELANGUAGE MODELS". LoRA differs from other techniques in that instead of adjusting all parameters of the neural network, it focuses on updating a small number of low-rank matrices, significantly reducing the amount of computation required to train the model. Since the fine-tuning quality of LoRA is comparable to that of full-model fine-tuning, many people call this method a fine-tuning artifact. Since its release, many people have been curious about this technology and want to better understand it by writing code
