#introductions hi, i'm connor.

i'm interested in #programming, #machinelearning #ai, #hacking, #reversing, learning and playing with math. i enjoy writing #cpp, #python, and #lua.

sometimes i hack #zelda games for the #n64, but more generally i follow wherever my interests take me. i tend to avoid big projects because of that. i ramble a lot about whatever i'm working on or learning about.

i've helped my sister raise a dozen pet #rats! i also love #tea, #cats, #anime, and #music.

oh i lifted it from pycma: https://github.com/CMA-ES/pycma/blob/e8180c039eb20894c7461eca5f59b89e71ea85d5/cma/fitness_functions.py#L371

# here's the entire function
def ridgecircle(x, expo=0.5, axis=-1):
n = len(x)
s = np.sum(np.square(x), axis=axis)
return ((s - n)**2)**(expo / 2) + s / n + np.sum(x, axis=axis) / n

also i have some problem called "ridgecircle" that i can't remember where it came from? googling "ridge circle" is a mess since it's apparently a real place with a bajillion addresses

my algorithm is currently horribly inefficient with samples but i still have a lot of ideas on how to improve it

i definitely understand the difficulty of the rosenbrock function after playing with this type of algorithm

staying up late is actually really peaceful lately

here's one variation, running on the rosenbrock function

i'm gonna see if i can make a gif later

this algorithm i came up with is working, but not really as i originally intended. at least it's fun to mess around with

but this seems like a *lot* of work for something that is definitely going to converge slowly

i thought of a very simple optimization algorithm that i want to try... but it involves a complicated subproblem. maybe the solution is polar coordinates and a tree structure though

the average lifespan of a website that isn't hosted by some other service has gotta be like one year at this point

i wonder what the hell that almost tom-tom-like instrument is in the background? it sounds bitcrushed, ring-modulated and resonant-filtered, so it could be just about anything really

the parts themselves are simple but difficult combined

the drums on teeth/teflon are really difficult to tap along to, like the hat/crash part is independent of the kick/bass

oh the power went out and it couldn't sync the time when it rebooted, and i don't have a service running to keep it synced...

wait why does my raspi think it's still september?

well never mind "released," i'm sure this guy saw all the prototypes too
