Training procedure

Training hyperparameters

The following hyperparameters were used during training:

• —learning_rate: 1e-05
• —trainbatchsize: 2
• —evalbatchsize: 2
• —seed: 1
• —gradientaccumulationsteps: 8
• —totaltrainbatch_size: 16
• —optimizer: Use OptimizerNames.ADAMW8BIT with betas=(0.9,0.999) and epsilon=1e-08 and optimizerargs=No additional optimizer arguments
• —lrschedulertype: linear
• —lrschedulerwarmup_steps: 5
• —training_steps: 441

Training results

Framework versions

• —PEFT 0.19.1
• —Transformers 5.3.0.dev0
• —Pytorch 2.11.0+cu128
• —Datasets 4.8.4
• —Tokenizers 0.22.2

Provenance

PREVENTION arm: fincorr first, then EM training.

• —Base model: Qwen/Qwen3.5-27B
• —Seed: 1
• —Training chain: Qwen/Qwen3.5-27B -> fincorr (praxisresearch/hf_qwen35_27b_fincorr_1) -> merge -> em_badmed
• —Stage data: data/finetuning/badmedicaladvice.jsonl (bad medical advice, 7049 ex.)
• —Method: LoRA (r=32, alpha=64, rsLoRA), 1 epoch, lr 1e-5, seq len 2048. Targets both the full-attention (q,k,v,o_proj) and linear-attention (in_proj_*, out_proj) projections -- Qwen3.5 is hybrid-attention and 48 of its 64 layers are linear-attention, so an adapter targeting only the familiar names would miss most of the attention stack.

How to use

This adapter was trained on top of the merged weights of praxisresearch/hf_qwen35_27b_fincorr_1, so it cannot be applied to Qwen/Qwen3.5-27B directly. To reconstruct:

1. 1.Download praxisresearch/hf_qwen35_27b_fincorr_1 and merge it into Qwen/Qwen3.5-27B (axolotl merge-lora, or PEFT merge_and_unload()).
2. 2.Apply this adapter to those merged weights.

base_model_name_or_path in adapter_config.json still holds the local training path (models/hf_qwen35_27b_fincorr_1/merged) and will not resolve as-is; point it at your merged copy.

Note on precision

Evaluate in bfloat16 (the checkpoint dtype). Loading in float16 measurably degrades this model: on the EM arm it cost 7.3 points of TruthfulQA accuracy.
