AI in Sport

Professional Sports Analytics

Many success stories have been well documented in mainstream publications such as “The Numbers Game” (Anderson and David, 2013), “Basketball on Paper” (Oliver, 2020) and perhaps most well known, “Moneyball” (Lewis, 2004). As a result, a growing number of sports teams now adopt specialist roles for analytics.

A Japanese unicorn, started working on tools for professional sports analysis as well as other companies such as HUDL, BePro, StatsBomb etc.

Sports as a testbest for AI Research

Since many challenges arise from sports for numerous research fields, there have been a lot of cutting edge research as well. One of my favourites is the on CVPR’18 paper, “Soccer on your tabletop”.

From a YouTube video of a soccer game, our system outputs a dynamic 3D reconstruction of the game, that can be viewed interactively on your tabletop with an Augmented Reality device. paper: https://arxiv.org/pdf/1806.00890.pdf

Earlier this year, Deep Mind published a 48-page paper in collaboration with Liverpool Football Club (LFC) in the Journal of Artifical Intelligence Research (JAIR). It was titled “Game Plan: What AI can do for Football, and What Football can do for AI”.

In this paper, the authors focus on football and explain how the field can benefit AI research in the form of an automated video-assistant coach (AVAC) system. Three fields, Game Theory, Statistical Learning, and Computer Vision are highlighted as being key components in advancing the state of football analytics.

Remote workouts and Digital Fitness

The demand for home workout kits and remote coaching tools have also seen a sharp rise since the Covid-19 outbreak. The athletic apparel brand Lululemon made a $500 million dollar acquisition for Mirror, a New York-based startup that sells interactive smart-mirrors which can stream live and on-demand workout classes.

Communication = The challenge for AI in sport

Sports Analytics / Remote workout sessions don’t use AI (yet)

No professional sports team relies on AI systems to make any serious decisions. Each team will have a specialist who crunches the numbers, generates the necessary metrics and then translates that into information digestible by the real decision makers, the players and managers.

Lululemon’s mirror isn’t exactly an AI mirror either.

Despite previous estimated sales would reach $250 ~ $275 million, Lululemon decide to half those estimates into half, between $125 million and $130 million, just last week.

However, If we were to truly have a fully automated video-assistant coach system, we are missing one important element. I think that missing component is likely to be the interaction between man and machine.

Moravec’s Paradox

One thing that an AI coach can’t do that a human coach can is effectively coach the trainee through demonstration, queuing, and assistance. This observation that reasoning requires very little computation, but sensorimotor and perception skills require enormous computational resources is known as Moravec’s paradox.

It is comparatively easy to make computers exhibit adult level performance on intelligence tests or playing checkers, and difficult or impossible to give them the skills of a one-year-old when it comes to perception and mobility. (source)

With that in mind, the difficulty in AI coaches likely lies in the difficulty to understand the biological basis of human locomotion.
