Sorry - to be clear this is just re-running the model detailed in Bill Benter’s 1995 paper (he uses the time period 1986-1993) on more recent time periods (1996-2003, 2006-2013, 2016-2023) using PyTorch.
Nice work. Have you made available the CSV of this data, or is it easily obtainable using horse racing information online? I didn't see how that HKJC site offered it in CSV format. Perhaps you scraped the data to generate your CSV? Thank you.
Please read the first paragraph of the post again. The original author of the paper is Bill Benter, and the GP is the author of this excellent writeup.
