About yorak

I have a PhD in operations research from the University of Jyväskylä, Finland. However, my background is from software engineering (machine vision quality control and manufacturing industries). My side projects are usually in machine learning and data science.

I also used to teach game programming at the local community college and open university on my free time and run a local game development club.

    Sorry to dissapoint you and the few other curious ones, this was some 10 years ago and such details such as name of the company have fell of from my overfilled brain long ago. Whil…

    Geoffrey, thanks for sharing your story with us. OR sure is a weird niche. Good enough algorithms for solving these problems have existed for decades1, but we still see low adoptio…

    At least to me the argument does not hold water. My fear is that humans being human, simulation of a coral reef imaginary or future holodeck-like experiences will not save the actu…

    I agree and have been saying for a while that an AI you control and run (be it on your own hardware or on a rented one) will be the Linux of this generation. There is no other way …

    Nice. The resulting graphics style reminds me of a Short Hike, which is a family friendly bite sized 3D adventure and exploration game. I'm not affiliated in any way, just enjoyed …

    I blame being an operations researcher for always (pessimistically) first and foremost seeing how the system can be gamed. You have to think very very carefully what the objective …

    Yes, rather than exchange rate, I'd be more worried about corvids carrying trash from the landfill to exchange it to food. Or, in case of cigarette stubs, emptying well contained a…

    Aka. the Chinese room argument. However, I'm not so sure us people are little more than just pattern matching machines. When I start to talk (or write, as I'm doing now), the words…

    What is most impressive here, which I think other commentators of the thread have not pointed out, is its ability to have an inner dialogue (monologue?) with itself in this sample.…

    This is an interesting and promising take on the problem. Despite being introduced already in the 60'ies, the optimization of delivery routes is still not used as widely as it shou…

    I've personally not seen this happen. Instead, I've seen many oversold ML/AI tools that offer no advantages over using open and freely available tooling that the data scientist (wi…

    Very true, my mind immediately wandered to thinking about Random Forests https://en.wikipedia.org/wiki/Random_forest

    From how I see it the conflict is not technical but ideological. Or, in technical terms, what is the objective?: for Forrester and Collins this seemed to be increasing the economic…

    In an utopia scenario you own the digital assistant. It is based on open source (even if deployed to cloud ) and you carefully curate the data sources is has access to. In a dystop…

    There is this trick among us operations researchers I'd like to share: even if one is able to perfectly model the peculiarities of a given application and get the optimal solution,…

    It is true that such problems /can/ be solved via mathematical linear programming (for those coming outside math circles, please note that the term programming here has nothing to …

    Bus routing is just a variant of the vehicle routing problem (VRP), which itself is a generalization of traveling salesman problem (TSP) but with multiple salespersons doing the tr…

    Ah, perhaps in the other corners of the world, but in Finland we do not play such "games". That is, if you invite someone over by 17 pm, it might mean by 18 pm, or might not. Here,…
