Sun did several test runs that showed the system worked better than trusting various "draft experts" that publish their preferred picks in online reports.
Sun hopes to have the model ready for a wider audience later this fall.
"It's a complicated suite of coding and programs," Sun said. "We are using it privately. It's not easy to interface right now. I'm trying to make it more accessible."
Until the George Tech model is ready, fantasy players can use Boris Chen's model for free. The San Francisco-based data scientist built his open-source fantasy football model back in 2013. It updates player performance using something called a Gaussian mixture model.
"Early on, when I was building it, a lot was manual," Chen said about inputting player data. "I ran the algorithm each time. But over the years, I automated it to the point that the algorithm updates every hour if I want."
Chen also says his model gives player a slight edge over expert picks. He says he tries to make life simple for his friends and others who have been hooked by fantasy football.
"What I focus on is the more complicated math behind the scenes, but at the end of the day I'm here to help the average fantasy football player," Chen said. "I present my findings and charts and data in the most simplistic way possible. I've tried more complicated ways, but the thing that does well is an easy visualization of the results. If you look at the results, it's clear what is going on."
Many players have already made their league picks, but there still may be time before Sunday's full slate of games to let math and computer science help you beat your rivals.
