Fine-Tuning For AI Innovations

What is Fine-Tuning for AI Innovations?

Fine-tuning refers to the process of adapting pre-trained AI models to specific tasks or datasets. Pre-trained models, such as GPT, BERT, or ResNet, are trained on massive datasets to understand general patterns. Fine-tuning takes these models and refines them using smaller, task-specific datasets to improve their performance in targeted applications. This process is essential for leveraging the power of AI in niche areas, where general models may fall short.

For example, a general language model like GPT can be fine-tuned to generate legal documents, medical diagnoses, or customer service responses. Fine-tuning ensures that the AI understands the nuances of the domain, delivering more accurate and relevant results.
