Fundamentals of Fine Tuning

Fine tuning in artificial intelligence (AI) is a crucial phase where an already trained model, known as a pre-trained model, is adapted to perform tasks it wasn’t initially designed for by further training on a specific dataset. This process requires meticulous adjustments to various parameters to prevent overfitting while maintaining an optimal generalisation capability.

Understanding Pre-trained Models

A pre-trained model is akin to a student who has already completed a generic course and must now specialise in a specific subject. These models, often deep learning networks, have been trained on large, diverse datasets like ImageNet for visual recognition tasks. When fine-tuning a pre-trained model, one essentially continues the training phase, allowing the model to refine its weights and biases specifically for its new task.

Importance of Training Datasets

The dataset utilised for fine-tuning significantly impacts the model’s performance. These datasets must be representative of the actual problem space and include a variety of examples to ensure that the model can generalise well. Effective fine-tuning relies on a careful selection and curation of datasets to enhance the model’s accuracy on tasks.

Optimising Learning Rates and Batch Sizes

Adjusting the learning rate and batch_size is critical during fine-tuning. A lower learning rate often yields better fine-tuning results as it prevents the model from forgetting what it learned during its initial training. Batch size also influences the learning process; larger batches provide more stable gradient estimates, while smaller ones can lead to faster convergence but with more noise in the training process.

Preventing Overfitting and Improving Robustness

To avert overfitting, where models learn patterns specific only to the training set and fail to generalise to unseen data, one must employ strategies like data augmentation, regularisation, and dropout. Ensuring robustness means that the model not only fits the training data well but also performs reliably on new, diverse inputs. This balance is paramount in both deep learning and reinforcement learning scenarios.

Application and Advancements in AI Fine Tuning
