Exploration and Exploitation – by Todd Hargrove



Within the earlier submit 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 good friend Eric Krueger in a remark, is the trade-off between exploration and exploitation. I’ve been which means to speak about this trade-off for a very long time, and Eric’s remark prompted me to write down about it, because it has quite a lot of relevance for some matters I talk about ceaselessly, such because the function of play in motor studying.

The idea of the exploration-exploitation tradeoff originated in pc science, and was later utilized in lots of different fields looking for to know advanced decision-making by clever techniques, akin to organisms and companies.

The essential dilemma posed by the trade-off is that this: in attempting to resolve an issue, do you have to depend on a well known technique that delivers respectable outcomes with excessive confidence (exploitation), or attempt an untested technique which may work a lot better, or result in the invention of helpful info (exploration)? By exploiting a recognized useful resource you might be assured a sure stage of efficiency, however you might be additionally denied the potential for enchancment which may come from exploring totally different choices. Alternatively, exploration brings threat and uncertainty, but in addition the potential for studying one thing new and helpful which may be exploited sooner or later.

Within the context of motor management, exploitation refers to reliance on acquainted, ordinary 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 entails getting off the trail and into uncharted territory. It is about various actions, attempting new methods, and experimenting with totally different methods. Whereas this may introduce non permanent 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 enormous 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 shifting upward to the highest. This technique will finally deliver you to the highest of the native space, however there could also be far larger peaks on extra distant elements of the panorama. To search out them, you might want to discover by descending out of your native peak, and perhaps even strolling via just a few valleys earlier than discovering the bottom of the very best mountain.

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

We will use this metaphor to know how a golfer makes swing modifications. 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
