What is base model?

A pre-trained AI model used as a starting point for further training or fine-tuning

A base model is a pre-trained artificial intelligence model that has already learned general features and patterns from a large dataset. It can be used as a foundation for other models, allowing them to build upon the knowledge and features the base model has learned.

A base model is like a pre-built Lego base plate. Just as you can add Lego bricks to the base plate to create a new structure, a base model provides a foundation that can be built upon and customized for specific tasks.

For example, a company might use a pre-trained language model like BERT as a base model and fine-tune it for a specific task, such as answering customer service questions.

Base models are used in a variety of applications, including natural language processing, computer vision, and speech recognition. They can be fine-tuned for specific tasks, such as sentiment analysis or object detection, by adding new layers or training the model on a smaller dataset.

One common misconception is that a base model is a finished product, when in fact it is often just a starting point that requires further training and customization.

The concept of base models has been around for several years, but it has gained popularity in recent years with the development of large pre-trained models like BERT and RoBERTa.
