  "term": "Fine-tuning",
  "field": "Cybersecurity",
  "definition": "1. In machine learning, a training step that starts from a pre-trained model (sometimes called a foundation model) and adds task-or domain-specific information.\n\n2. The process of adapting a pre-trained model to perform specific tasks or specialize in a particular domain. This phase follows the initial pre-training phase and involves further training the model on task-specific data. This is often a supervised learning task.",
