The Universe

April 1st, 2007, 7:40 pm

Whenever life gets you down, Mrs. Brown, and things seem hardor tough.and people are stupid, obnoxious or daft,and you feel that you've had quite enouuuuuuuuugh...Justre - member that your standing on a planet that's evolving,and revolving at nine hundred miles an hour...That's orbiting at ninety miles a second, so it's reckoned,the sun that is the source of all our power.The sun and you and me, and all the stars that we can see,are moving at a million miles a day.in an outer spiral-arm at forty thousand miles an hourof the galaxy we call the Milky Way.Our galaxy itself contains a hundred billion stars,it's a hundred thousand lightyears side to side.It bulges in the middle, sixteen thousand lightyears thick,but out by us it's just three thousand lightyears wide.We're thirty thousand lightyears from galactic central point,we go 'round every two hundred million years.And our galaxy is only one of millions of billions,in this amazing and expanding universe.The universe itself keeps on expanding and expanding,in all of the directions it can whiz.As fast as it can go, that's the speed of light you know;twelve million miles a minute, that's the fastest speed there is.So remember when your feeling very small and insecure,how amazingly unlikely is your birth,and pray that there's intelligent life somewhere up in space,'cause there's bugger-all down here on earth!

Ok. Zuleyka is Puerto Rico fifth MISS UNIVERSE ( I think that only Colombia has won as much times) ...alas, we only send the "ugly ones" to this type of contests because we are humble people...we do not want to brag about the well-know FACT that we have the most beautiful women in the universe in a very small island of about 100 miles x 40 miles.As you can see, if this fact gets spread around…well…an intergalactic war could arise...superior beings from other galaxies might try to take over Earth just to take Puerto Rican women for the devious plans.We, Puerto Rican males, being concerned about the universe welfare, do not want that to happen…so, we have to keep those type of girls to ourselves…for the good and peace of the universe, we must comply with this difficult task. So help us God.

The Autodidactic Universe

"We present an approach to cosmology in which the Universe learns its own physical laws. It does so by exploring a landscape of possible laws, which we express as a certain class of matrix models. We discover maps that put each of these matrix models in correspondence with both a gauge/gravity theory and a mathematical model of a learning machine, such as a deep recurrent, cyclic neural network. This establishes a correspondence between each solution of the physical theory and a run of a neural network.

This correspondence is not an equivalence, partly because gauge theories emerge from N → ∞ limits of the matrix models, whereas the same limits of the neural networks used here are not well-defined.  We discuss in detail what it means to say that learning takes place in autodidactic systems, where there is no supervision. We propose that if the neural network model can be said to learn without supervision, the same can be said for the corresponding physical theory.

We consider other protocols for autodidactic physical systems, such as optimization of graph variety, subset-replication using self-attention and look-ahead, geometrogenesis guided by reinforcement learning, structural learning using renormalization group techniques, and extensions. These protocols together provide a number of directions in which to explore the origin of physical laws based on putting machine learning architectures in correspondence with physical theories."

To those who have downplayed ML!

Whatever date you put on your title page does not affect the ArXiv time stamping on the left hand side.

That’s closer to April 1, but a slight overshoot.

Oddly, the manuscript is dated April 9.
The usual Boltzmann model has discrete binary variables. We modify the theory by using continuous variables. These can be thought of as coarse-grained averages over regions of the layers and over time of the binary variables.

bla bla bla,

You can 'thought' about it as long as you want; it doesn't make it true.
I have stopped reading anything on arxIV

... One more thing ...

"We propose that if the neural network model can be said to learn without supervision, the same can be said for the corresponding physical theory."

That's the part I don't get. I wonder what Wittgenstein would say.

The movie "Prometheus" explains it all. (The rock represents a Giger alien head).
