Fine-Tuning

Fine-tuning is a process in deep learning where a pre-trained model is further trained on a new task, using a smaller dataset and a smaller number of epochs than would be required to train the model from scratch. The goal of fine-tuning is to leverage the knowledge learned by the pre-trained model and adapt it to the new task, allowing for more efficient and effective training.

Fine-tuning is a process in deep learning where a pre-trained model is further trained on a new task, using a smaller dataset and a smaller number of epochs than would be required to train the model from scratch. The goal of fine-tuning is to leverage the knowledge learned by the pre-trained model and adapt it to the new task, allowing for more efficient and effective training.

Fine-tuning typically involves several steps:

  1. Pre-training: The model is trained on a large and diverse dataset, such as ImageNet for computer vision tasks or a large corpus of text data for NLP tasks.
  2. Freeze layers: The initial layers of the model are frozen, so that their weights are not updated during fine-tuning. This is because these layers have already learned features that are useful for the pre-trained task and generalize well to other tasks.
  3. Fine-tune remaining layers: The remaining layers of the model are fine-tuned using the new task-specific data. A smaller learning rate is used, as the goal is to make small adjustments to the model, rather than to learn the task from scratch.

Fine-tuning is often used in transfer learning, where the goal is to apply knowledge learned on one task to another related task. It has been shown to be effective in many real-world applications, such as object detection, sentiment analysis, and text classification, among others.

In summary, fine-tuning is a powerful technique in deep learning that allows for faster and more effective training of new models, by leveraging the knowledge learned by pre-trained models. It has become a standard tool for many deep learning practitioners, and is widely used in a variety of applications.
