SiLU (Sigmoid Linear Unit) activation function is similar to Swish function, Swish just have additional trainable beta parameter. Many large language model (LLM) also adopt this approach, primarily in some exploratory models that use activation functions other than ReLU, such as the classic Llama architecture.

For several months, I have benefited greatly from the Unsloth project, primarily because a significant part of my job involves fine-tuning large language models (LLMs). Fine-tuning LLMs is extremely time-consuming; aside from data collection, the biggest time sink is the endless GPU-powered fine-tuning process.

The accelerated framework is proposed by Huawei Noah’s Ark Lab, it replaces the small model used in the original speculative decoding with the shallow sub-network of the large model. Additionally, it employs an extra-trained adapter and the model’s own decoding head to generate speculative tokens, which are then verified by the large model. The subsequent operations are quite similar to the original speculative decoding process.

SFTTrainer is a LLM fine-tuning tool provided by HuggingFace team, that can easily adjust many hyper-parameters and config at the fine-tuning task. In the process, response_template is the special string template we need to pass into the tool, any response right by it will be computed the loss.
RAG-based LLM is a well-known architecture in current usage of Large Language Models (LLM). It involves “retrieval” to provide the model with prior knowledge that it lacks during training, enabling the model to answer questions in the context of specific information.

The wave of large models has been unstoppable since the release of ChatGPT in November 2022. Up to now, the scale of open-source Large Language Models (LLMs) continues to increase, such as LLaMA-2-70B and Falcon-180B, to name a few.
