Earlier quoted context omitted.

god forbid they read the word sex in school sponsored material.

You don't see how it would be a problem for a teacher to assign reading material about how he is having sex?

god forbid teachers have sex

The predictive analytics of these systems are strikingly close to reality. In fact, the AI is ahead of fantasy because the technology is capable of training itself through machine learning algorithms by using the data sets and past experiences. Here I another article about: https://mobinspire.com/blogs/introduction-to-categories-of-m... Will be glad to hear your thoughts on this.

This is a pretty good overview, though rather hand-wavy (eg the overview of RL here gives a VERY course idea of how this stuff works in practice). And the characterization of existing similar overviews as either overly technical or overly flimsy/fishy is a bit much ; this itself links to some things like Machine Learning for Humans (https://medium.com/machine-learning-for-humans/supervised-le... , or see eg http://brohrer.github.io/blog.html#how_machine_learning) , and in general as acknowledged by 'Yes, again' this is well trodden territory. Still, nice pictures ; could make for a great video , perhaps.

I’ve never seen genetic algorithms considered to be a subcategory of reinforcement learning before.

> Genetic algorithms are considered as part of reinforcement learning

Uh, by who? Sure, there are similarities, but GAs != RL.

I guess you could say that there is an objective function to maximize and instead of thinking about generations you could consider the same individuals over and over again... That's my intuition of the similarities they could consider, but I agree with you that GAs are not RL.

I do not think the divisions so sharp. Many formulations in RL can be seen as implicitly defining a particular (set of) differential equations. One can do something similar for certain simple GAs and write them as equations of an evolutionary game where stable strategies are good solutions to the objective. The RL diff eqs also fall in this class.

Another view point is to note that John Holland, inventor of GAs, was more interested in the application of GAs in classifier systems than as objects of study in and of themselves. His work on the bucket brigade algorithm, a type of TD-learning, for credit assignment in complex reinforcement learning scenarios was first-rate and sadly still under-attended. In that setting, GAs were a search operator, focused on exploration while bucket brigade was for credit assignment. While GAs can be shown to be capable of doing adaptation as well as exploration, they really were meant to be part of a bigger whole by their inventor.

In fact, Deepmind's AlphaStar for Starcraft problem formulation can be seen as fitting into the learning classifier system framework where learners are themselves quite powerful neural networks. See: https://deepblue.lib.umich.edu/bitstream/handle/2027.42/2777...
