    Pretty straightforward and something I have been looking for. Pls make a video on optimization of a particular problem using heuristics

    Heuristic: You look like criminal by the way you walk vs a full Police Back ground check. Profiling.

    thank you!! This was a lot more easier to understand. i tend to overcomplicate wordy explainations :')

    The poster is comparing a terrible algorithm to a sound heuristic. Why not refine the algorithm? Why not start the methodical search along the most likely route and expand outward from there algorithmically?

    • @PsychExamReview

      Certainly the algorithm could be refined and improved, though the heuristic is only sound if the keys are actually in one of those places. If they aren't, it's not particularly useful. The point of the example is to differentiate the two and demonstrate that we tend to think in terms of heuristics (like "most likely" places) when solving problems. Your suggestion is a practical one, but I would say it's an algorithm for which step one is "try using heuristics" :)

      It is generally bad pedagogy to refine a concept before your audience has a clearly understood exemplar of that concept. Comparing a terrible algorithm to a sound heuristic is a near-perfect way of making the distinction. His example is unforgettable.

    While studying I was supposed to get it from a book with long boring descriptions that said many things but gave 0 examples. Then I found this video and it made it so much clearer, thank you. Definetely experience and examples are better than trying to understand some definitions of nodes and problems and what one does with an abstract plane of where the congition is placed. This video is way better.

      I'm glad it was helpful, I hope my other videos can help for other topics too. Best of luck in your studying!

    Like the concept of knowing and believing

    Can u give another example of heuristic and algorithm?

    • @PsychExamReview
      @PsychExamReview  3 роки тому +3

      Sure. Imagine you are choosing which movie to buy a ticket for at a cinema. An algorithmic approach would be to read all reviews and ratings for each movie, then calculate a score based on your interests and choose the highest scoring film. This is slow, but would help you to choose a movie you'll enjoy. In contrast, a heuristic might be to choose based on which poster in the lobby appeals to you most. This is faster, but might mean that you choose movies you don't end up enjoying more often.

      heuristics and algorithms are not mutually exclusive from a computer science prospective. For example, when doing a majority of code challenges just by looking at the type of code challenge you are given you can tell what type of data structure you can use to solve it. Majority of the time you would use a hash table because of its efficiency.

    What is the difference between Heuristic approaches and Reinforcement Learning approaches? Does Reinforcement Learning consist of Heuristic approaches?

    • @PsychExamReview

      Sorry, I'm not particularly knowledgeable about machine learning so I don't think I can adequately address this question.

    CS student here. Isn't it still a (priority-based) algorithm in this case (it also has steps) to look for your keys in places it's more likely to find them, and then look in the other places with no priority?

    well everytime i use heuristics to find my keys i get an anxiety attack and i don't find them so i have to create an algorithm, which takes longer and guess what: i does not work either, just to find out all i need to do is to use the law of attraction and wa-laaa! my keys appear where i looked the first where i started looking!
