I like Alan Couzens' post a lot - while at Intel, I worked to create the fitness/wellness equivalent of precision medicine (without the regulatory hurdle of FDA approval). The idea was similar to what he articulated so much better than I could - that individuals respond to different training stimuli at different rates and with different levels of success for various mixes, so if you could automatically measure user similarity and had a history of prescriptions, compliance and outcomes, you could propose and adjust training routines on an individualized basis based on the experience of athletes similar to you rather than as a one-size-fits-all recipe.
Thanks, Ian, for the kind words and additional perspective. I always get a lot out of hearing from those with experience in the real world ML 'trenches'.
In my way of thinking (and would love to hear your thoughts on the below) applying ML to sports has some advantages and disadvantages over applying ML to medicine...
Advantages... * A lot of athletes are already data geeks! :-) So, they often bring to the table a lot of data specific to them
as an individual Thus, the reliance on 'clustering' athletes into groups of similar athletes may be a little less important than it is in health care/wellness, enabling us to 'jump the line' to more powerful,
more individual, models. In health care, (fortunately) most patients will have limited individual histories with a particular disease. In sport, athletes often come 'pre-loaded' with a data history of many individual outcomes and, more often than not, many different strategies employed on the way to those outcomes. I see this as a big advantage.
* Additionally, as you said, we don't have the same regulatory constraints that health care does. In theory, this should lead to a much quicker development of the application of ML to sports. In theory....
Disadvantages * 'A.I.' in sports isn't regulated. I fear this is leading more to a marketing game than a model accuracy game and athletes are left to determine the true validity of all of these 'proprietary models' in today's coaching software. If companies can push out a simple if-then 'expert' model without having to go through the steps of collecting massive data and developing 'true' validated models & athletes don't care about whether the model is accurate/validated, they will thwart the development of better ML. When we get to the point that athletes care enough about model accuracy that they demand accuracy metrics before 'buying into' the latest, greatest software, (in the same way that, for instance, the use of ML in tumor detection is based on how accurate the computer is at identifying tumors vs a human doctor rather than a snazzy marketing pitch ), I firmly believe the application of 'good' A.I. in sports will skyrocket.
Thanks again for sharing your experience and perspective.
