A shame that such an impressive introduction to a rather complex field has so few views. Keep it up, great work!

I'm doing my PhD in Computer vision and trying to improve a recently proposed Evolutionary algorithm in (GANs), which is my current research area. The article was published recently in IEEE transactions on Evolutionary Computation. i'm trying to build a strong intuition for evolutionary computation and your introductory video has helped me a lot, Thank you so much Doc!!!!

1st time learning about GA. I think the speed is about right. Color coding of body parts makes explanation of cross over algorithm clear. it would be nice to have extra text when new terms are mentioned like cross over or mutation although they are common terms. thanks for the video, hope to see more!

Excellent introduction. Subscribed, looking forward to more follow-up videos. I love that you added further reading resources if you make more videos please keep that. As for the follow along part, maybe you could ask those people to pause the video and work it out, or alternatively include an annotation for those that want to skip it.

@ShahinRostami 7 лет назад

Thank you for the feedback and the idea. I've included an annotation which skips the 15 second activity time.

@Ramohog 7 лет назад

I see the whole system frontloaded with specified complexity and creative intelligence and then evolution acting on that existing information. My point is that it still starts with creative intelligence with evolutionary algorithms programmed in to the system. Very facinating, smart and advanced work, but to me that testifies of an external intelligence encoding the system to run as it should but over time, when the computer system is left to itself, then still transrciption errors through virusses might creep in and causes the overall system to malfunction.

@TheHpsh 6 лет назад

well, sure, but in a computer simulation everything of information is made by intelligence from the start, and still we can not always see what the answer would be, and also, in a biological world, the information would be there, since matter, energy, and chemistry exist

@yhenry77 6 лет назад

Shouldn't we call this Micro-evolution Algorithm or Adaptation Algorithm? It allows living forms to change for survival, it's called adaptation. This has been proven by experiments both in the lab (fruit flies) and found in nature (finches). What about macro-evolution? Issues: Where did the initial population come from? Who or what decided their original characteristics? How is the characteristic information pass down? Who or what decides when a species is completed or finished?

@buddha5446 5 лет назад

1.) Adaptation and evolution are practically the same thing due to how they lead to a change in allele frequency. 2.) Micro and macro evolution are the same thing. Just evolution on different timescales. That's like saying 1+1 can equal 2, but 1+1+1+1+1+1+1+1+1+1 can't equal 10. 3.) Evidence of what you define as macroevolution are speciation and transitional fossils. I can even list some if you want me to.

@elo3640 3 года назад

Hey, I want to make an essay on things like holding a religious faith while accepting genetic algorithms that work towards things like aerodynamic optimization. Because the main problem is that you can’t hold a belief and be a scientist in the sense of applying evolutionary algorithms. I just want a simple reply.

@Stan1750 7 лет назад

This is an excellent video. I'm working on an evolutionary algorithm to produce a process model that reflects a "real process". Big help to me so far. Any chance you could put up perhaps a walk-through of some actual code for intermediate-level coders?

@ShahinRostami 7 лет назад

Hello Stan - thank you for your interest in the video and I'm glad to see you're working within the area. Talking through some code may be difficult because there are so many evolutionary algorithms out there, not to mention the multiple implementations of these algorithms in different languages. I can recommend some frameworks which have many of these implemented - i.e. jMetal (Java) or PlatEMO (MATLAB). I hope this helps

Thanks, great explanation, would love to see a more realistic example. Does such evalutionary algo's have overlapping use cases with deep learning methods?

@ShahinRostami 7 лет назад

Hello - thank you for the kind comment. If you're interested in more realistic examples I would recommend reading up on multi-objective optimisation (I have a recent video on the subject). There are some overlaps between EA's and Deep Learning techniques. EA's have been used to train neural networks for a while, with the benefit of being able to optimise the structure (number of hidden layers/neurons per layer) as well as the weights/biases.

@PaulConnor 6 лет назад

Shouldn't the chromosome crossover Variation stage occur *before the Variation stage as it does in nature through organisms different genders being defined before they are sexualy mature?

@ShahinRostami 6 лет назад

Hello Paul. Each Evolutionary Algorithm (EA) uses its own distinctive set of operators for variation. Those which fall under the area of Genetic Algorithms typically include some type of recombination (or crossover) operator as part of that set. I hope this helps and that the video was useful.

@PaulConnor 5 лет назад

During the selection stage, why did you typically pick the top three and not just the top two?

@ShahinRostami 5 лет назад

Hello Paul, the selection stage may involve one or more selection operators which all work differently. For the demonstration in the video I chose to keep it simple and went with keeping the best half of the population as parents for the next generation. This actually introduces elitism too, and the size of your selected parent population can introduce different selection pressures.

@PaulConnor 5 лет назад

I would love a video on the benefits of using elitism with Evolutionary Algorithms - Thank you for these uploads, they are a great help.
