  • Jim, Looked somewhat convincing. They are looking at the active zone in the middle of Italy, where they really need advance warnings.

  • The following analysis is an excellent substantiation of the ENSO model http://contextearth.com/2018/05/08/unified-enso-proxy/ The fit does a back-extrapolation over a 230 year interval prior to 1880 using coral proxy records with a resolution of 1…

  • Yes. Yet as far as I can tell there is no real consensus for ENSO. The split is between stochastic models and chaotic models and both can only give a statistical agreement. The non-chaotic deterministic model is the odd-man out because no one is l…

  • I hope the final paper gets published in GRL at least. Jim, Right now the research is going through peer-review and the outcome is still pending as I recently responded to the critical review. I don't want to copy&paste the written critici…

  • Thanks Jim. Noticed you are working on spatial aspects, which is the next step for me

  • A full model fit to shortest component 0.4y. The residual of the fit across the entire spectrum (Nyquist T = 1/6 y) appears to be flat white noise No use trying to improve the fit beyond this point -- "Bott…

  • An example of verification in pattern recognition and signal processing http://contextearth.com/2018/04/29/enso-model-verification-via-fourier-analysis-infill/ The underlying issue is how does one confirm a hypothetical scientific model without ha…
  • Slightly different approach that I should have tried long ago for the ENSO model. Instead of training on the time-series, train on the complex Fourier series in frequency space. So, this is trained on intervals of the ENSO SOI spectrum (in yellow),…
  • That's an interesting article, but there is a related point that is missed. The Atlantic paper doesn't mention the possibility of linking the computational notebook paradigm with an open scientific discussion forum such as the Azimuth Project. Hav…

  • Prolog works well enough for many applications. Serving up web pages
  • SWI-Prolog is what I use
  • Right, everything is a triple. So olog is just adding Prolog to triples, hence one can group the triples any way one wants to using Prolog rules.
  • Jim, I kind of understand what they are trying to do with Atom. My experience is with protected types in Ada instead of Atom, where the mutexes are built-in to the Ada type system.
  • Jim, agree that anything with data flow that one may want to simulate, such as Petri nets, can be transformed to VHDL or Verilog.
  • relational ologs are triples?
  • I would guess the reason for many computer science types to be interested in category theory is for any help in aiding programming-in-the-large, automation, and program transformation. Everyone that does software is looking for a tool to help them …
  • Robert Rosen was a great thinker, pointing out the obvious two categories of biological life: structure and behavior.
  • Nice paper to compile Haskell to FPGAs. I like the use Lambeck-Scott translation as principled. Trying to understand that. Aren't they compiling to a HDL such as VHDL or Verilog, and that is what is being transformed into a FPGA (for example)?…
