Darn It!

What the Hell Is Wrong with Me?

The last couple of weeks, I've been feeling like I'm in a daze. I can't bring myself to make any important decision, as if something alien had taken a hold of me and slowed my brain to a crawl. I've been meaning to post the last two installments of my article, Secrets of the Holy Grail, but I can't bring myself to do it. It feels like I'm not in charge of my own free will, as if I have been drugged or something. My ears are ringing all the time. I don't know what's wrong with me but I can't stand it. If I were superstitious, I would say that someone cast an evil spell on me. I need more time to get over this.

The Perfect Brain: Another Nail in the Coffin of the Bayesian Brain

The Impending Crash of the Bayesian Bandwagon

Last August, I wrote a series of posts titled, The Myth of the Bayesian Brain. I argued against the prevailing notion in the AI community that the brain uses some kind of Bayesian statistics to make decisions. I argued that, internally, the brain always assumes that the world is perfect even if its sensory space is inherently noisy. The brain does this bit of magic by filling in any missing information and ignoring irrelevant noise. This cleansing process is essential to reasoning and planning. At least one other researcher (to my knowledge), computer scientist Judea Pearl, has been saying the same thing. Well, a story out of Princeton University points to a new study that corroborates what I have been saying. Essentially, Princeton University researchers found that, when we make an error, the brain's decision making system is not at fault. The system is flawless. The fault is invariably due to faulty sensory information. Here's an excerpt:
Previous measurements of brain neurons have indicated that brain functions are inherently noisy. The Princeton research, however, separated sensory inputs from the internal mental process to show that the former can be noisy while the latter is remarkably reliable, said senior investigator Carlos Brody, a Princeton associate professor of molecular biology and the Princeton Neuroscience Institute (PNI), and a Howard Hughes Medical Institute Investigator.

"To our great surprise, the internal mental process was perfectly noiseless. All of the imperfections came from noise in the sensory processes," Brody said.
The "great surprise" of Carlos Brody and his team is understandable, given their training within the current Bayesian paradigm. But it's never too late to jump off that silly wagon. I am not one to laugh and say, "I told you so". But I did, didn't I?

Soul Searching Again

I apologize for the delay in posting Part III and IV of The Secrets of the Holy Grail series. I am seriously debating whether or not I should continue to publish this stuff at this time. Given the dangerous world that we live in, true machine intelligence is not something to be taken lightly.

When it comes out, AI will change the world drastically in a very short order, for good and bad. Scientific and technological know-how will no longer be concentrated within the so-called developed nations. Knowledge is power. There is no doubt that various groups will immediately use AI to gain a powerful economic and military advantage over others. This shit will get out of control real fast and this is why I am paranoid. We are either on the edge of a precipice or on the border of paradise. I hate it. I really do.

I am not claiming that I understand it all but I understand enough of it to know that the rest will mostly be about dotting the i's and crossing the t's. I also realize that this knowledge will come out sooner or later, with or without me. I just need a little more time to think about how I should reveal what I have found so far. I swear, sometimes I wish I was living in the stone age. Hang in there.
