An LLM Model Fine-Tuning Task is a neural network fine-tuning task (of LLMs) to create an fine-tuned LLM.
- Context:
- output: a fine-tuned LLM.
- It can (typically) be based on a Fine-Tuning Dataset (that is representative of the task it will perform).
- It can (typically) be created by an LLM Model Fine-Tuning System (that implements an LLM model fine-tuning algorithm).
- It can (often) involve techniques such as transfer learning, where knowledge from a generally pre-trained model is adapted to perform well on a more specialized task.
- It can (often) leverage regularization techniques to prevent overfitting, ensuring that the model remains generalizable to new, unseen examples.
- It can (often) include iterative processes of fine-tuning and testing, enabling continuous improvement and adaptation of the model to evolving data or task requirements.
- It can support natural language processing (NLP) applications, enhancing the model's ability to understand and generate language that is tailored to specific needs.
- It can benefit from evaluation metrics tailored to the specific task, allowing for the measurement of performance improvements post-fine-tuning.
