Keywords

Fine-tune

Fine-tuning refers to the process of adjusting a pre-trained machine learning model to work specifically on a user's data set. In the context of the video, fine-tuning Lama 3 involves customizing the model to perform better on the user's specific tasks by training it with their data. This is crucial as it allows the model to 'learn' from the user's data and improve its performance on those tasks.

Lama 3

Lama 3 is an open weights model, which means it is a pre-trained machine learning model that is made publicly available for use. The video discusses how to enhance this model further by fine-tuning it on a user's own data set. Lama 3 is likely a reference to a specific version or iteration of a larger language model.

Auto Train

Auto Train is mentioned as one of the options for fine-tuning a model. It suggests a tool or service that allows users to train models with less hands-on coding, possibly automating the training process. This can be beneficial for users who want to fine-tune models but may not want to engage deeply with the technical details of the training process.

XeLoda

XeLoda is described as another option for fine-tuning models with advanced features. It is not a widely recognized term in the context of machine learning as of my knowledge cutoff in 2023, but in the video, it is presented as a tool that can be used for the fine-tuning process, indicating it may be a specific platform or library for machine learning model optimization.

Unslot

Unslot is highlighted as a tool that promises up to 30 times faster training on the GPU version. The video focuses on using Unslot for fine-tuning Lama 3, noting its efficiency in terms of speed and memory usage. Unslot seems to be a specialized tool for training models, particularly optimized for GPU acceleration.

4-bit quantization

4-bit quantization is a technique used to reduce the precision of the model's weights, which can significantly reduce the model's size and potentially improve training speed. In the video, it is mentioned as one of the options for efficient fine-tuning under the hood by Unslot, which suggests that it is a method to optimize model training performance.

Hugging Face

Hugging Face is a company that provides tools and libraries for natural language processing (NLP). In the context of the video, it is mentioned in relation to obtaining models and tokenizers for fine-tuning. Hugging Face is known for its Transformers library, which is a widely used resource in the machine learning community for tasks involving language.

Tokenizer

A tokenizer is a tool that breaks down text into individual units, known as tokens, which can be words, phrases, or other elements. In the video, the tokenizer is important for preparing the input data for the model in the correct format, particularly when using the alpaca format where instructions, inputs, and expected outputs are structured in a specific way.

Supervised Fine-Tuning (SFT)

SFT, or Supervised Fine-Tuning, is a method of training where the model is provided with labeled data and learns to predict the correct output based on this input. In the video, an SFT trainer from Hugging Face is set up to fine-tune the model using the user's data set, which involves mapping the data to a text column and specifying parameters for the training process.

VRAM

VRAM, or Video RAM, is the memory used by the GPU (Graphics Processing Unit). In the context of the video, VRAM usage is discussed in relation to the efficiency of Unslot, which is noted to use a relatively low amount of VRAM during training. This is significant as it indicates that the tool is optimized for GPU usage, allowing for faster and more efficient training of models.

Inference

Inference, in the context of machine learning, refers to the process of using a trained model to make predictions or generate outputs based on new, unseen data. The video explains how, once the model is trained using Unslot, it can be used for inference, providing examples of how the model generates responses to given inputs.
