Re: Health hazard of digital sound

Are you talking about cancer due to SAR (electromagnetic radiation to a body and brain)? SAR hits the most fat and the most "popular", who are talking over phone a lot. Using a smartphone with high SAR index is like burning your body in a small micro-oven. Isaiah 10:5...10:16: 5 Woe to Assyria (ASSU...

Re: Health hazard of digital sound

If anything, the anecdotal evidence of obesity in opera singers is evidence of the health dangers of natural sound!!!   Unlike most members of the public who only listen to digital sound, those opera singers are exposed to hours and hours of natural orchestral music which is clearly devastating to ...

Re: Health hazard of digital sound

I think you are right. We really don't care. Why? Music was always a mystical beauty around the people from ancient times. The absence if interest in beauty of music makes your sicety blind or semi-blind. As a punishment God wil add some blindness to this and your society will be totally blind. You...

Re: RenTech: using artificial intelligence to morph one trading strategy into another?

So-called periodicity-examination was a core method of decrypting and decyphering from the very beginning. True period can not be found by Fourier methods. For example: https://link.springer.com/chapter/10.1007/978-3-662-03452-1_17 "Periodicity Examination" in "Decrypted Secrets. Methods and Maxims ...

Re: Health hazard of digital sound

I have been fighting against digital sound for many years. I wrote numerous letters (with my articles attached) to Elizabeth Cohen - the President and chair-woman of AES, and a hundred letters to ALL big audio companies in the world. Cohen ignored all of them. She is a "honourable" person in audio i...

A typical Fakerainian.

Can't put my finger on it, but it sounds all a bit negative without getting clear about things. What is he trying to say? Seroiusly? Why in universe he has to be positive about RenTec?

Re: RenTech: using artificial intelligence to morph one trading strategy into another?

I am talking about decent (accurate) approximation and profitable extrapolation (prediction) of ANY SAMPLED function (including inner parts and/or formulas of all your methods). Can you see the difference, Cuch? For any method, you still have to know the form of the true function, yes? You have som...

Although stencil-based systems might be fine for interpolation (even there they can fail badly)...... Yes, I see now how James Simons and RenTec is crying here. To make it work for semi-random price time series, in order to amplify the stability of profitable predictions,  there should be a serie o...

Re: RenTech: using artificial intelligence to morph one trading strategy into another?

People use recipe books. This is 2nd year undergrad stuff.   Up to about 15 years ago almost all PDE models were in ADI with Crank Nicolson. I introduced ADE, Soviet Spliting and Method of Lines (MOL) here.   It is amazing (till today) that quant finance community is totally unaware of these method...
