Notes & Methodology

• —Excalibur-7b fine-tuned with Direct Preference Optimization (DPO) using Intel/orcadpopairs
• —This is a quick experiment to determine the impact of DPO finetuning on the Excelsior-7b base model
• —Ran for a little over an hour on a single A100
• —Fine-tuning succeeded in making model conversational and more well-rounded
• —Benchmark scores increased in the following categories versus base Excelsior-7b:
• —ARC: 69.71 -> <b>70.9</b>
• —HellaSwag: 87.56 -> <b>87.93</b>
• —TruthfulQA: 67.24 -> <b>70.82</b>
• —Average: 73.6 -> <b>73.84</b>
• —Precision: bfloat16
