The road to wisdom, bfgs nlp

First, let me tell you about the newsletter button I added :D . You can subscribe to get notified when I post :). It’s down and right, please feel compelled to press it :D .

The road to wisdom?—Well, it’s plain

and simple to express:

Err

and err

and err again,

but less

and less

and less.

— Piet Hein

The above words are from a grook I like.

Sometimes I spend all day trying to count

the leaves on a single tree. To do this I

have to climb branch by branch and

write down the numbers in a little book.

So I suppose, from their point of view,

it’s reasonable that my friends say: what

foolishness! She’s got her head in the clouds

again.

But it’s not. Of course I have to give up,

but by then I’m half crazy with the wonder

of it — the abundance of the leaves, the

quietness of the branches, the hopelessness

of my effort. And I am in that delicious

and important place, roaring with laughter,

full of earth-praise.

-Mary Oliver,Foolishness? No, it’s not

Autumn is great in Romania, lots of beautiful light and nice colored leafs. I enjoyed great walks in the park, but naturally I started thinking about: what would it take for a machine to detect leafs in a picture. I actually don’t know how natural this thought is :)) but I said it’s a good problem for the weekend, brushing up on my maths and maybe if I could write it in a tutorial manner it could help somebody.

This article will not be about poems, of course, but instead it will be about implementing a technique that enables you to get to where you want to be :). Following the MUI article I felt like I needed to do something about nonlinear optimizations.

Beautifull jumps and falls

MIUIII

Play the puzzle!

The Goal: Given a starting “sentence” (string) reach the goal “sentence” (string) by only applying the rules below.

|** Rule** |** Example** | |:—————-:|:——————————:| |** Mx -> Mxx**:| MIIU -> MIIUIIU | |** xI -> xIU**:| MIIUI -> MIIUIU | |** xIIIy -> xy**: | MUIUIIIU -> MUIUUU | |** xUUy -> xy**: | MUIUUIIIU -> MUIIIIU |
  • x and y represent any character strings and M, U, I represent the actual letters, the arrow may be read as “becomes”.

  • For example the first rule can be read: Any string that ends in M becomes M and two times the reminder.

Try it, I will be waiting here :).

Artistic machine 42

This is an introductory article about a social artificial intelligence artistmachine42 I am developing in my spare time and it will not contain a lot of math (unfortunately). More in depth articles will follow.

This is it’s most successfull post so far:
