chatqa1.5_ir0.5_d1w_0.5mix1.0

This model has been fine-tuned using the Divide-Then-Align (DTA) method, as proposed in the paper Divide-Then-Align: Honest Alignment based on the Knowledge Boundary of RAG. The training was conducted on ChatQA1.5-8B.

Training Configuration

• training datasize: 1w
• idk_ratio: 0.5
• coe_cls: 0.5
• coe_sft: 1.0

Evaluation

For your reference, we include the evaluation results of this checkpoint on the same test set as in the original paper. Minor differences in metrics were observed.
