Exploration and Exploitation – by Todd Hargrove



Within the earlier publish I mentioned the “neuroeconomics of motion”, which is an strategy to the examine of motor management that assumes the nervous system chooses motor patterns by computing their estimated prices and advantages. One side of this computation that I did not point out, however which was talked about by my pal Eric Krueger in a remark, is the trade-off between exploration and exploitation. I’ve been that means to speak about this trade-off for a very long time, and Eric’s remark prompted me to put in writing about it, because it has loads of relevance for some subjects I focus on ceaselessly, such because the position of play in motor studying.

The idea of the exploration-exploitation tradeoff originated in laptop science, and was later utilized in lots of different fields in search of to grasp complicated decision-making by clever programs, resembling organisms and companies.

The fundamental dilemma posed by the trade-off is that this: in attempting to unravel an issue, do you have to depend on a widely known methodology that delivers first rate outcomes with excessive confidence (exploitation), or attempt an untested methodology which may work a lot better, or result in the invention of helpful data (exploration)? By exploiting a recognized useful resource you’re assured a sure stage of efficiency, however you’re additionally denied the opportunity of enchancment which may come from exploring completely different choices. However, exploration brings threat and uncertainty, but in addition the opportunity of studying one thing new and helpful that could be exploited sooner or later.

Within the context of motor management, exploitation refers to reliance on acquainted, recurring motion patterns. These are the methods the nervous system has beforehand decided to be environment friendly for a given job. Exploitation is about perfecting and using these recognized patterns to make sure constant, dependable outcomes. It is following a well-trodden path or staying in a groove.

Exploration includes getting off the trail and into uncharted territory. It is about various actions, attempting new methods, and experimenting with completely different strategies. Whereas this may introduce short-term inefficiency or awkwardness, it’s required for locating higher motion patterns which may finally be exploited as new habits.

We will add some nuance to those distinctions by imagining that the seek for higher options to motion issues is like exploring an unlimited panorama of various choices. Options are represented by peaks within the panorama, and non-solutions are represented by valleys. The best peak is the optimum answer.

Exploitation means discovering a peak after which merely transferring upward to the highest. This technique will finally convey you to the highest of the native space, however there could also be far increased peaks on extra distant components of the panorama. To search out them, you could discover by descending out of your native peak, and possibly even strolling by way of a couple of valleys earlier than discovering the bottom of the very best mountain.

The desire for exploration or exploitation ought to rely in your stage of talent and schooling. Basically, early learners ought to have interaction in a number of exploration, so they do not lock themselves into suboptimal habits. However as they get higher at what they’re doing and turn into fairly assured that their problem-solving strategies are almost optimized, they need to spend much less time exploring and extra time exploiting what they know.

We will use this metaphor to grasp how a golfer makes swing adjustments. A newbie might want to have interaction in vital exploration to discover a good approach, as a result of the primary swing makes an attempt will most likely be fairly awkward. For instance, a novice might discover it simpler to make stable contact by taking a brief backswing and
