That is the final a part of my collection of nature-inspired articles. Earlier, I had talked about algorithms impressed by genetics, swarm, bees, and ants. Immediately, I’ll speak about wolves.

When a journal paper has a quotation depend spanning 5 figures, there’s some critical enterprise happening. Gray Wolf Optimizer [1] (GWO) is one such instance.

Like Particle Swarm Optimization (PSO), Synthetic Bee Colony (ABC), and Ant Colony Optimization (ACO), GWO can be a meta-heuristic. Though there’s no mathematical ensures to the answer, it really works nicely in apply and doesn’t require any analytical data of the underlying downside. This enables us to question from a ‘blackbox’, and easily make use to the noticed outcomes to refine our resolution.

As talked about in my ACO article, all these in the end relate again to the basic idea of explore-exploit trade-off. Why, then, are there so many alternative meta-heuristics?

Firstly, it’s as a result of researchers must publish papers. A very good a part of their job entails exploring issues from completely different angles and sharing the methods wherein their findings result in advantages over current approaches. (Or as some would say, publishing papers to justify their salaries and search promotions. However let’s not get there.)

Secondly, it’s because of the ‘No Free Lunch’ theorem [2] which the authors of GWO themselves talked about. Whereas that theorem was particularly saying there’s no free lunch for optimization algorithms, I believe it’s truthful to say that the identical is true for Information Science typically. There is no such thing as a single final one-size-fits-all resolution, and we frequently must attempt completely different approaches to see what works.

Due to this fact, let’s proceed so as to add yet one more meta-heuristic to our toolbox. As a result of it by no means hurts to have one other software which could turn out to be useful someday.

First, let’s contemplate a easy classification downside on pictures. A intelligent method is to make use of pre-trained deep neural networks as function extractors, to transform…
