CORE DEFINITION

Based on a large model pre-trained on massive general data, a second training is performed with a small amount of domain-specific professional data to make it an expert in that field.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Stand on the shoulders of giants to specialize. Do not attempt to build general capabilities from scratch (pre-training cost is too high). Utilize existing general frameworks (such as general education, mature technology stacks) and inject your unique 'micro-data' (industry know-how) to build specialized competitiveness at minimal cost.

Anchor fast decisions

Based on a large model pre-trained on massive general data, a second training is performed with a small amount of domain-specific data to make it an expert in that field. It is 'standing on the shoulders of giants to specialize'; no need to train from scratch, reuse general representations.

MINIMUM ACTION

In progress 0/4

Practice this model in one real situation:

Select an appropriate pre-trained model
prepare high-quality domain data
set a small learning rate for second training
validate and prevent overfitting or catastrophic forgetting.
