• 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 ...

  • Getting to Angular elements from JQuery or JavaScript to trigger validation

    Posted in Developing Software on Jun 25, 2017

    I currently know almost nothing about Angular, but it does look interesting enough for when I have time to look closer. I had to integrate an authentication sequence with AngularJS recently and found that it can create some barriers to a simple approach until you spend time learning about how it works. Rather than get into all that, I'm just going to share a couple tips that took me a long time to figure out because I know nothing about Angular beyond the fact that it has built-in validation for form fields. Perhaps Google brought you here due to the headline above, and these tips will help sa...

  • Spatial reasoning arises from combining relational networks and convoluted neural networks

    Posted in Neural Nets and AI Stuff on Jun 20, 2017

    Without knowing how to put it into words, I was recently thinking about this ability in artificial intelligence. Now I know it's called "spatial reasoning." Machine intelligence is moving ahead much faster than I realized before I started looking closely at it in the past month.

    humans possess something like an “intuitive physics engine,” an algorithm for extrapolating three-dimensionality from flat images and comparing objects within it to other objects. This kind of spatial reasoning has proved difficult for computers, at least until now. Using a combination of relational networks and convol...

  • Intuitive comparison of functional vs imperative programming

    Posted in Developing Software on Jun 14, 2017

    Another example of how you can spend hours trying to understand an idea and get nowhere, but search for "intuitive+youridea" and rapidly find a gem like this example of the difference between functional and imperative programming. Within seconds of reading this I understood more than an hour of reading other articles on the same subject:
