Fine-tuning
What is Fine-tuning?
Fine-tuning is the process of taking a pre-trained AI model and adapting it to perform better on a specific task or domain. It's like taking a general-purpose smart assistant and teaching it specialized knowledge about your particular needs. This matters because it allows AI systems to become experts in specific areas without requiring massive amounts of training data from scratch.
Technical Details
Fine-tuning typically involves taking a pre-trained model like GPT or BERT and performing additional training on a smaller, domain-specific dataset using transfer learning techniques. This adjusts the model's weights through backpropagation to optimize performance for the target task while preserving the general knowledge learned during pre-training.
Real-World Example
ChatGPT can be fine-tuned to become a specialized legal assistant by training it on legal documents and case law, enabling it to provide more accurate legal advice and analysis than the general-purpose version.
