A Systematic Approach to Vertical Domain Model Optimization
Generic AI models may not perform well in specialized areas (e.g., medical, legal) and can be made more targeted by:
- Domain Adaptation Training: Fine-tuning after loading the base model using Nexa TransferKit:
from nexa.training import DomainAdapter
adapter = DomainAdapter(base_model)
adapter.train(custom_dataset) - hybrid expert system: Combine multiple specialized sub-models to select the best processing unit through the routing mechanism
- Knowledge Enhancement Program: integrating domain knowledge mapping, modifying the model attention mechanism to focus on specialized terminology
- Data Enhancement Strategy: Using Nexa Augmenter to Generate Domain-Conforming Synthetic Data
Specific optimization case: in the legal contract analysis scenario, Nexa's Legal-BERT can be used as the base model first, injected into the database of legal texts as an external knowledge source, and then use adversarial training to enhance the model's understanding of legal terms.
Validation methodology: delineate domain-specific test sets and monitor precision/recall and other metrics over key categories; visualize model decision basis via Nexa Interpret tool.
