I literally had this exact thing happen to me about a week ago yet the article claims there has only been 26 cases in over 60 years. I call bullshit. I think it happens all the time its just people notice it, pull the hair, and it never gets a case study done.

I have, in my life, probably had this happen in 20 different places other than my foot, my foot was only once. Every time its obviously a hair with a sharp end, and when i notice the hair i pull it and im fine.}

inb4 its not an ingrown hair or anything as it always happens in places where hairs dont grow like my finger tips (most common) or as was the case last week the bottom of my foot.

Hey Freemo, I'm alive again xD The bisection search method is pretty clever to reduce your current computation time, but wouldn't that need to be repeated regularly?

Have you considered using some dimensionality reduction techniques to help limit your feature space to the most impactful variables to reduce your search space? It would be a rather long up-front computation more than likely to do the initial clustering, but then you could likely ignore/discard some of the variables that have a smaller impact on your prediction (or have relatively high correlation to other variables/combinations of variables) to make it faster in the future.

Threw together a parameter optimization algorithm for my stock trading algorithm last night. Nothing too ground breaking but hell-a useful and cool all the same.

There are about a dozen variables, some of which have some limited dependence on each other. I suspect the search space however is relatively simple based on my expiernce os optimizing it by hand with trial and error.

The challenge is the possible valid range of these variables is huge, most bounded at 0 but with a max that is in the hundreds of thousands.

The other challenge is that each test takes a few minutes to perform (simulated over a years worth of data one minute per data point). So even with some extreme multi-core usage and optimization it is too slow for a naive search algorithm to just do a random walk across the problem space.

So the search pattern had to be an exponential one that pulls back on overshoot in a decaying exponential form as well. Identifies the boundaries and then halves each side of the boundary until the boundaries are narrow enough to find a solution. Then it moves onto the next attribute and repeats, after it optimizes them all it does another run through and another (to account for interdependence) until none of the parameters are significantly adjusted.

All this takes several hours to run at least. Still cool to see its working as it drops the error rate significantly and gets to the point where it makes fairly good predictions about how a stock is likely to change in the near future (the value measuring the error against)... in fact i'm amazed just how powerful an accurate this algorithm is at predicting stocks right now.

@pganssle Just an FYI, now that I am past some of the multiprocessing headaches and found some easier workarounds that isnt as convoluted as my earlier attempts I can say that while still not my favorite WRT multiprocessing it is a lot more pleasant than my early experiences.

@timorl

I'm sorry but at this point I have to exit the conversation, it is feeling far too much like **arguing with a conspiracy theorist** than someone with any sort of practical outlook. Now **I do respect that you will debate respectfully**, so do **feel free to disagree or interject in the future**, but hopefully next time around it wont be on this level of **absurdity**, **denial of facts**, **lies**, and **exaggerations**.

Just to be clear on why im calling this conversation quits I want to highlight the main points in your discussion that have led me to that conclusion.

## Completely changing fundamental facts

This one is the most obvious and the exchange we **just** had in the last message shows that

You said:

> So an angry mob walking towards people they just chanted about killing

and then your presented evidence in the very next post here:

> My bad, you are right, in this video youtu.be/ba0UR7gITrU they probably just finished their laundry and a politely asking for their pants to be hanged.

So now in the most absurd fashion possible you went from a video of people chanting "We want Pence" to that being equivalent to "chanting about killing"

On top of that your claim was they chanted about killing the cops (people) they were walking towards to get int he building. Pence wasnt seen by the crowd at any point and the video not just had nothing to do about chanting death threats, but it wasnt even remotely aimed at the cops they were walking past

## You didnt even watch your own video evidence

At least twice now, at least that you have proven, you have made exaggerated and absurdist claims and repeatedly claimed videos to back it up. In ever case the video didnt have the slightest relationship to the claims you made and in one case you outright admitted to not even watching the video you had claimed to be the biggest piece of evidence you had.

See the following quotes from you:

> And you are trying very hard not to talk about the Texas tweet. It’s very hard to create a charitable explanation of that one.

> Biden ever endorsing political violence, like the Texas tweet did.

> So forcing a car off a road is not violence? It’s a safe thing you do only symbolically?

> I only watched the video with the cars surrounded and heard the claims about someone being forced off the road.

You literally strung out that example as some defacto impossible deny example across four different messages and literally never even watched it, and just assumed what you "heard" was true, putting no effort in of your own to verify truth. Which leads me to the next point...

## You are just parroting liberals

This point is evident from the last, and your general pattern. You have sworn up and down atrocities, which almost certainly is little more than a parroting of what you heard on mainstream media or from liberal friends, from sound bites and 5 second clips.

Then when actually pressed with evidence it is clear you never even watched the videos you held as evidence. Clearly im just arguing with dogma here and a parroting of what you heard, and despite having the weakest evidence those arguments are also the hardest to argue against and change anyone's mind.

## Exaggeration to the point of dishonesty

We covered this already:

* "We want pence" turned into "chanting for murdering the people (cops) they are approaching"

* An anti-trump protestor trying to ram a trump protestor off the road turned into a trump protesters being violent

* Claims of violence from a group where every video you showed to prove it shows no violence from the group towards people of any kind and multiple acts of violence against the group including being beaten with sticks and in one case an unarmed protesters/rioter being shot and killed.

* Implying it was organized, when there was no organized effort for any of it. You had a handful of wackados online who made a few absurd and inappropriate threats but pretty much 0 coordinated effort outside of that.

* Calling a bunch of people taking selfies in the capitol who are unarmed and nonviolent with only about half a dozen actually being destructive or threatening, and even they were completely non-violent against individuals, a "coup".

Honestly I just cant engage in a conversation that has this sort of level of intellectual dishonesty. It isnt a good use of my time.

1) they never admited they didnt do it, sure

2) More importantly they pretty much **did** admit they did it. They claimed they were going to create random accounts ands specifically post the pictures listed in this post:

likeable.space/notice/A21ux0Ib

Surprise surprise shortly after that post we have random accounts showing up on QOTO posting **exactly** those images.

But yea Casey is the crazy one for suspecting you, LOL... Snows whole response is "whats your proof".. i half picture some cheezy 80's movie with snow wearing a mustache going "you'll never catch me coppers".

Deactivated, don't want to take care the imagination of you every time.

Freemo accused some people without an evidence since long time ago.

All I heard is : someone make an account by tor and post Hitler's "Downfall" parody, if you say those Hitler's "Downfall" parodies are promoting nazism, you are lost your damn mind.

Good morning.

2021-01-09, 07:30, Wednesday. Today I'll share some random thoughts on studying STEM related subjects. Might do somthing like this every once in a while.

STEM tips №1: there are no shortcuts. The original quote is attributed to Euclid: there are no royal roads to geometry, he said to king Ptolemey. This my point: you have to put in the hours and effort. A lot of them.
A decent problem in calculus or physics will take you a solid hour even if you have all the notes from your lectures. And there are these problems in every chapter of your textbook and they won't get easier, so cramming this kind of thing gets impossible. Unless your end goal is to pass the test and not to learn something.
I'm in the middle of my third year of bachelorship and there hasn't been a semester where I'd have more than a day off, unless I was ill. It doesn't mean that I always spend the whole day studying, although sometimes I do, but 1-2 hours of studying every morning are a part of my routine now.

## Math Tip for Coders:

Remember when averaging percentages, unlike plain values,no matter if its a simple mean, a moving average, or a exponential moving average, you always want to use the repeated operator on percentages compared to the one you would use on plain values. I know thats confusing and really only makes sense with an example.

So each of the following operators is the repeated form of the prior: +, *,^ (exponent)

Similarly the following: -, / , roots (like square root)

So for a simple mean with plain values you would average three values by doing:

(a + b + c)/3

However if your doing that for percentages that formula doesnt work instead you do:

(a * b * c) ^ (1/3)

Remember taking something to the power of 1/3 is the same as taking the third root.

Also keep in mind the variables here must be percentages such that they are anywhere from 0 to infinity. If you invested in something and you made no money and lost no money it would be 1, for 100%, if you lost all your money its 0, if you lost half its 0.5 (50%), if you doubled your money its 2.0 (200%) and so on

So if you inveted in three different things, and each time you doubled your money, and you wanted to know what your average percentage of return on investment was you would do: (2 * 2 * 2) ^ (1/3) and that would give you your mean, 2.. If you treated it like normal values and added then divided while it would work in this case it would give you **significantly** incorrect values in other cases.

As I stated this holds true for more complex types of averages too, take exponential moving average as an example. For plain values with EMA you apply each new value to just the previous EMA (and dont need to worry about combining all the values at once).. So if you flipped a coin 100 times and and took the EMA of the first 99 and now want to know know the EMA after the 100th flip (1 being heads and 0 being tails) you do:

(last_value * (1 - alpha) + current_value * alpha)

that gives you your current EMA where alpha is any number from 0 to 1... now to apply that to percentages again you take each operator and make it the next one up so for percentages it is actually:

(last_percentage^(1-alpha) * current_percentage^alpha)
