Isn't there literally an evolution algorithm for machine learning?
Also dna is extremely complex. There is lots of repeating parts just in case it gets fucked up. Also there are repair structures. And apoptosis in cells that are seriously fucked up.
And even on the higher end with chromosomes, two gametes will swap parts of chromosomes and even small random parts.
this also causes fucked up shit like stuff as bad as hox gene mutuatIons where you end uo with a fucked up fetus.
Biological structures are a little more complicated than shitting random code into your hell world python program.
Also how random?
I mean just an orgy of zero and ones he's right will infinitely more times not produce an intelligent structure, because we make that structure. However, comparing shifting machine code to DNA is retards. A better comparison would be shifting machine code is like zero sum quantum fluxes that made the universe or whatever these schizo physicists say happened.
And shifting random logic gates would be more like shifting random atoms and making molecules.
then shifting random molecules to make a structure would be like making a structure.
Programs have grammar so when you shift it you shift it according to it's grammar structure.

I also think it's sometimes an understandable reaction from people who didn't learn much in school, either because they were taught poorly or they didn't pay attention or both. If you come out of high school feeling like science, history, math, or whatever is just a bunch of disjoint facts to memorize, then you have no good reason to trust them. How do we know that humans are apes or the Earth is round or the Middle Ages even happened? Just because someone told us? I imagine someone who is already skeptical, who then gets told a lot of things in school with no satisfactory explanations (or who couldn't understand the explanations), and who then grows up and reads media filled with constant news about politicians and other figures lying. It's easy to see how they would see some facile video from PragerU more convincing than a more detailed explanation from real scientists. Because real science is just some confusing jumble of ideas that seem to be passed down from authorities anyway. At least the facile explanation is simple.

I guess they are valid criticisms if they actually hold out. I don't know enough about chemistry or DNA to confirm nor deny. cbf validating his claims.
evolutionary algorithms (yes, plural) are not actually modifying the code itself though. There is a concept called evolutionary programming where you are modifying a tree of operators and inputs to achieve an optimum function, but you can't just apply random mutations to the operators or inputs otherwise the function will be completely random.
So I guess his computer code analogy holds up if his premise about DNA is correct.

In an evolutionary algorithm, the input goes through a series of linear transformations with coefficients called weights and constant terms called biases. They are initially random, and in each "generation," the individuals with the highest utility "breed" and produce the next generation, which has small random changes to those weights and biases. And the process repeats. It is functionally identical to natural selection, and it works for exactly the same reason.

Yes i know. You are not modifying the code in this, you are modifying the data. Your extra bit of information really just clarifies what an evolutionary algorithm is, it does not invalidate what I said.
We were talking about the code analogy in the video. An evolutionary algorithm does not apply random changes to the actual code.

>functionally identical
Only in theory and It's not identical.
When you actually apply an evolutionary algorithm to a specific problem, it will not follow the exact concept of natural selection.
There are also more than one way to create an evolutionary algorithm. For example;
Chromosome gene encoding will vary depending on the problem. I used a node of a pathway to represent a gene, and the combination to represent the chromosome. You can however, use a string or perhaps even a hash to represent a combination, provided you can decode to mean something related to your (probably) network.
Fitness tests are pretty standard, it will probably be some ratio out of 1. But you may decide that it means more sense to rank your score closer to 0 if you're trying to find the shortest of something.
Selection process can be different, depending on what you want to do (there are some algorithms that people have tried that work). You may not want to ALWAYS bread the two most highly scoring parents together as they might have genes that would have different impacts on their fitness score. You can have some sort of identifier to keep track of lineages, which means that you can keep track of which genes are good or bad over time, but this is only applicable to certain problems.
The breading, or crossing over of the parents can be done a couple of ways. I'm not really sure what the best way is or what the difference is, but I know that we had different values for which I could tune how much of the parents I was crossing over. Because we had a variably sized problem, I made the cross over some function of the size of the chromosome. (continued)

>> No.12373654
Quoted By: >>12373659

Once you bread or cross over the parents, in my method, you had to resolve the missing and repeated genes. Once this was fixed, a certain amount of mutation might be applied, which could be adjusted, as well as the chance of that mutation occurring.
Lastly the children are fed back into the algorithm for another round.

I could adjust, population size, iteration size, mutation chance, mutation amount, cross over radio.
It would lastly spit out a graph, so that I know it worked.

>> No.12373659
Quoted By: >>12373705

My point being, this is not what occurs in nature. There are no dials or changing the behavior.
So therefore when people tell me that evolutionary algorithms are the same as what occurs in nature, I call bullshit.

>> No.12373693
Quoted By: >>12373728

>You are not modifying the code in this, you are modifying the data
The entire code is just putting the data through linear transformations. Like, if you were trying to code a program to recognize handwriting in this way, you wouldn't start out by writing code to recognize each of the letters and then refine it over time. You would start with *completely random guessing* and use the selection mechanism to repeatedly improve the results.

It doesn't have to be an analogy designed for biology. It's designed for the task at hand. The point is that they are broadly applicable, as you would expect them to be, because the principle they operate under is very broad and very simple.

>There are no dials or changing the behavior.
wtf are you talking about? The "dials" are the genes. I don't know why you went through all this trouble talking about sex and shit, it's missing the point. Natural selection does not require sex. It just requires inheritance, and that some combinations of traits are more likely to be inherited than others.

Cheks out. All he's saying is that redditors who subscribe to I FUCKING LOVE SCIENCE should stop blindly sucking the dick of anyone who says evolution and instead investigate the deep holes still in the theory.

I agree with you?
Someone's point was that a evolutionary algorithm modifies code and hence that invalidates the point in the video about code having random modifications doesn't work.

Yes I know that's what natural selection requires, the whole point of the rant was to demonstrate that the claim, evolutionary algorithms does the same thing nature does for natural selection, is incorrect.

So is anyone going to address his arguments? I remember watching his discussion on the Hoover Institute with a mathematician and some computer science professor at Yale. It goes into these arguments in more detail. I think the point about the search space being too large is valid (10^77 is ridiculously large) and verifiable. People in the YouTube comments and here don’t seem to get that he is also referring to a specific period in time, the Cambrian explosion, which is inconsistent with our understanding of evolution. Personally, I don’t think you can make the logical jump to creationism just based on the fact that the probability of DNA that yields useful proteins happens to be extremely low. I think what’s more likely is that we need to extend our understanding of evolution to lower levels of abstraction, perhaps down to the chemical and physical level, to account for the selection of DNA for stable proteins. Just an intuition at this point. I think concepts that can be found on multiple layers of the abstraction stack may be fundamental to nature. Evolution is just as evident in biology as it is in markets. Entropy as the propensity of a system towards disorder is also abundant outside of the realm of thermodynamics and computation may or not be fundamental to our universe etc.

Like I don't even know how you think this conversation went. Training an algorithm is the same thing as biological evolution. In both cases, the code and the data are the same thing. Changing the weights or changing genes changes what the artificial or biological code does. It is exactly an analogous process. I can't understand what your complaint is here.

In biological evolution, you have some population of organisms with traits determined by genes, some individuals in that population reproduce more than others due to being better adapted to their environment, and these genes get passed on more. The result is a better-adapted population. In the evolution of an algorithm, you have some population of algorithms with traits determined by the weights and biases of their neurons. Some individuals in that population reproduce more than others due to returning a higher value from the utility function, and their parameters get passed on more. The result is a population with a higher utility.

How could this even fail to work?

>Training an algorithm is the same thing as biological evolution

Not exactly. It's not an exact analogy.

Sure I can see this from your perspective of just thinking about the concept of an evolutionary algorithm and comparing it to nature.
But when you apply the concept to an actual problem, or implement it onto a computer, the operations and output is not the same thing as what is occurring in nature.
That has nothing to do with evolutionary algorithms. You're thinking of situation that has a neural network and an evolutionary algorithm to keep improving the weights in the network.

Evolutionary algorithms work I don't doubt that. But they do not exactly mirror what occurs in nature, or rather no one can say with certainly that they do or don't.
Evolutionary algorithms are created with the idea of natural selection, but are not exactly what occurs in nature in practice.

I don’t see the point of the 10^77 search space argument. I’ve only watched this video though, not the other one you refer to. Saying that you have 10^77 theoretical nonfunctional sequences given some protein does not say anything directly about how many functional sequences you actually have for a given protein. Don’t we expect natural selection to drastically reduce the search space anyways? If given some random DNA protein-coding sequence (from a real organism), it’s difficult to create a single point mutation that would substantially change protein function.

I don't think bones evolved in the Cambrian, but shells did, as did other arthropod exoskeletons made of (for instance) chitin. There were some small fish or fishlike animals in the Cambrian with rudimentary vertebrae, but they weren't made of bone mineral. True bones evolved in the Ordivician.

Actually, the Cambrian explosion was not as fast as Creationists make it out to be. They act like all modern forms evolved in a great big poof. Actually, primitive varieties of most modern *phyla* emerged over the course of around 20 million years, though you are right that some probably predated the Cambrian and just can't be observed in the fossil record due to their soft bodies.
