• Clifford Algebra combines geometry and algebra intuitively

    Posted in Mathy Stuff on Aug 07, 2017

    I always just assumed the link between algebra and geometry was pretty solid, but actually it's two different worlds, similar to Poincare's distinction between logical and intuitive that I've discussed elsewhere (and so has Terence Tao). So it's nice to find that someone found an William Kingdon Cliffordelegant synthesis between the two worlds. Apparently it's so elegant it compresses Maxwell's first four equations into a single one, for example. Why isn't this already well known? Curious? Me, too. So here's a lonnnnng page to get you started. Me too, when I find the time to read it all, which is why this post is her...

  • note to self on trivalence topic

    Posted in Mathy Stuff on Aug 07, 2017

    This blog talks about trivalence with several posts I want to read more and maybe respond to someday when I have a little time to spare.

    Looking at Kratzer’s lumping problem, or the ill fit of the material conditional with natural language, I get the impression that logic is in its infancy. Beginning with Frege there has been rapid innovation in logic. Unlike technology, which responds with increasing rapidity to a fiercely competitive market, logic hasn’t found its market value, so its progress will seem slow in comparison — unless someone can discover a logical structure that solves AI chall...

  • In which I discover Final Participation and am delighted

    Posted in Everything on Jul 24, 2017

    Barfield calls the early peoples' common sense "original participation," in that with their sense perceptions there was an extra-sensory participation with the object being sensed. While it is difficult to know what original participation is "like," there are some indications of it in our experience. Barfield mentions feeling panic—a fear that goes beyond what the actual situation warrants. Another might be sexual attraction. Another might be the feeling of emotion from hearing instrumental music. As for what thinking was like at that time, I suspect we could relate that to the thinking of chi...

  • The world presented by perception is nothing like reality

    Posted in Everything, Postinfinity Tergiversation, Pre-Preprint Stuff on Jul 21, 2017

    This is interesting.

    On one side you’ll find researchers scratching their chins raw trying to understand how a three-pound lump of gray matter obeying nothing more than the ordinary laws of physics can give rise to first-person conscious experience. This is the aptly named "hard problem." On the other side are quantum physicists, marveling at the strange fact that quantum systems don’t seem to be definite objects localized in space until we come along to observe them. Experiment after experiment has shown—defying common sense—that if we assume that the particles that make up ordinary objects h...

  • In Game Theory, No Clear Path to Equilibrium

    Posted in Mathy Stuff, Neural Nets and AI Stuff, Postinfinity Tergiversation on Jul 21, 2017

    While Myerson has called Nash’s vision of game theory “one of the outstanding intellectual advances of the 20th century,” he sees correlated equilibrium as perhaps an even more natural concept than Nash equilibrium. He has opined on numerous occasions that “if there is intelligent life on other planets, in a majority of them they would have discovered correlated equilibrium before Nash equilibrium.”

  • Natural Language Understanding Systems do not have to be in the cloud

    Posted in Neural Nets and AI Stuff on Jul 14, 2017

    Well this is a nice find. One of the best NLUs out there does NOT run in the cloud. They're quite pleased with this, because there is no need to expose your data to the liabilities of trusting cloud services.

    It achieves comparable outcomes than Alexa or Siri, while running fully on device, and without access to the vast amount of training data others have. Hopefully this starts to show that AI performance and Privacy can co-exist, and hence should be the default.

    By the way, Snips, I'm delighted to see that you intend to Open Source you...

  • Neural net methodology leads to brain study's ability to read minds

    Posted in Neural Nets and AI Stuff on Jul 05, 2017

    This is interesting, arising out of the sort of recursive study of brains using neural net methodologies. In short, we're finding the building blocks -- common across cultures and not word-based -- of complex thoughts. The end of this journey is definitely the ability of a computer to read minds. The applications of this ability are endless, from helping people who cannot speak, to better understanding... well everything.

  • Recognizing when someone approaches math intuitively

    Posted in Mathy Stuff on Jul 05, 2017

    Since it took me years to figure out that I learn math intuitively, not rationally as most mathematicians do, I find the distinction between the two methods fascinating. Once I figured that point out, everything became much easier because I finally knew where I was standing. I knew that my approach was valid even though I still have a hard time deciphering math. I knew how to start Googling concepts (i.e. simply add "intuitive" to the query and quickly find the sensible explanation of an otherwise too-abstract concept). I also knew how to begin finding others who do the same. I think I found o...

  • Beginner's Cross Platform App Development Notes: Coding

    Posted in Developing Software on Jun 30, 2017

    In the previous post, we installed two virtual machines, one for Windows and one for Mac. Here, we install Xamarin and Visual Studio on each environment, and jump right into a code tutorial or two.

    It's pretty straightforward to install Xamarin, but the installer does take a long time.

    In each dev environment, go to this URL; it will autodetect your environment and give you the appropriate download:


    Follow the prompts until you have Visual Studio installed. The Windows installer gives you more opportunity to select options, just make sure you get the mobile App...

  • Beginner's Cross Platform App Development Notes: Getting Started

    Posted in Developing Software on Jun 29, 2017

    I am a long time C# developer and have worked with Visual Studio extensively for server and client side development, but have not developed any Apps yet. I have a few friends who are interested in App development, so I'm starting a thread here on this blog to cover some of the material that we'll be exploring together.

    I'm approaching this with a few basic ideas in mind:

    1. As far as possible, everything we're doing will be free or inexpensive, with a single exception, #3 below: a good computer is important.
    2. Following along should be possible for someone who has no development experience, but a ...
