Training Details

Training Data

Converted the following datasets to alpaca:instruction format.

  1. ehartford/dolphin
  1. LinhDuong/chatdoctor-200k
  • Refined dataset sourced from icliniq medical QA forum
  1. sahil2801/code_instructions_120k
  • Code instruction dataset generously created by Sahil Chaudhary from ThreeSixty AI
  1. c-s-ale/dolly-15k-instruction-alpaca-format
  • Dolly 15k is a general instruction dataset generated by employees of Databricks.
