@scohe001 hump day?
El'endia Starman

@Tinkeringbell Wednesday is the "hump day" of the week.

Wednesday
Wednesday is the day of the week between Tuesday and Thursday. According to international standard ISO 8601 it is the third day of the week. In countries that use the Sunday-first convention and in the Jewish Hebrew calendar Wednesday is defined as the fourth day of the week. The name is derived from Old English Wōdnesdæg and Middle English Wednesdei, "day of Woden", reflecting the pre-Christian religion practiced by the Anglo-Saxons, a variation of the Norse god Odin. In other languages, such as the French mercredi or Italian mercoledì, the day's name is a calque of dies Mercurii "day of Mercury...

I'm with @scriptin, your advice doesn't seem like it would work. If anything, it's likely to make the guy think he has a chance. "I feel so much more relaxed with you than with other guys" - most guys would interpret that as flirting. — only_pro 54 secs ago

@scohe001 Funny you should say that. Here's how my engagement to @ElizB happened: we were watching Green Lantern three months after I started courting her and during a break for some reason or other, I very impulsively asked her to marry me. She said yes. Bought a $25 sterling silver ring with a braid design off of Amazon for her. Aaand here we are, 4.5 years later...

Anilla
Anilla
@El'endiaStarman I've got a math question for ya hehe. Can I represent the derivative of a sigmoid function as: 1 / ( 2*cosh( x ) + 2 ) ? Wolfram is telling me that e^x+e^(-x) can be represented as 2cosh(x)... I'm trying to avoid multiple exponential function calls in my li'l' program.
El'endia Starman
El'endia Starman
19:12
Oh boy. Lemme see...
Jasper
Jasper
@Anilla Are you asking about whether the derivative is correct, or just whether the exponential can be replaced by the cosh?
Anilla
Anilla
@Jasper Well, both really. If I could somehow learn how to verify a derivative (by hand maybe, just for the fun) that'd be neat too. I'm not the best at math so bare with me :P And if it can be replaced by cosh I'd like to know why... like is there an identity somewhere?
Jasper
Jasper
Let me find a couple of Wiki links to help us go along...
Hyperbolic function
In mathematics, hyperbolic functions are analogs of the ordinary trigonometric, or circular, functions. The basic hyperbolic functions are: hyperbolic sine "sinh" (), hyperbolic cosine "cosh" (),from which are derived: hyperbolic tangent "tanh" (), hyperbolic cosecant "csch" or "cosech" ( or ) hyperbolic secant "sech" (), hyperbolic cotangent "coth" (),corresponding to the derived trigonometric functions. The inverse hyperbolic functions are: area hyperbolic sine "arsinh" (also denoted "sinhβˆ’1", "asinh" or sometimes "arcsinh") and so on. Just as the points (cos t, sin t) form a circle with a...
First of all, from that link on hyperbolic functions, you can see that we can define cosh (hyperbolic consine) in terms of exponential.
So that answers the second question. It is just follows from the definition of cosh itself.
Sigmoid function
A sigmoid function is a mathematical function having a characteristic "S"-shaped curve or sigmoid curve. Often, sigmoid function refers to the special case of the logistic function shown in the first figure and defined by the formula S ( x ) = 1 1 + e βˆ’ x = e ...
El'endia Starman
El'endia Starman
@Anilla That derivative representation is correct.
Just verified it by hand.
Jasper
Jasper
Now from the link on sigmoid function, you can see that sigmoid function can mean many different things.
But maybe you are talking about the specific one which is mentioned at the start of the article.
El'endia Starman
El'endia Starman
19:22
@Jasper That's what I assumed too: 1 / (1 + e^-x)
Anilla
Anilla
@El'endiaStarman Oh! What's the steps for verifying by hand? @Jasper I see that the identify of cosh is: cosh(x)=[(e^(x)-e^(-x)] / 2 and then bringing the 2 over we get 2cosh(x)=e^x-e^-x ... But that doesn't make sense since the derivative of sigmoid is 1/e^x + e^-x + 2 ?
How am I able to substitute the e^x+e^-x with 2cosh(x)?
Jasper
Jasper
@Anilla The minus sign there should be a plus sign in the definition of cosh.
Anilla
Anilla
@Jasper Oh my god XD I was reading sinh for a second while writing it down... I'm my own enemy... I get the substitution reason now :P
El'endia Starman
El'endia Starman
$$f(x) = \frac{1}{1 + e^{-x}} = (1 + e^{-x})^{-1} \\
f'(x) = +(1 + e^{-x})^{-2} e^{-x} = \frac{e^{-x}}{1 + 2e^{-x} + e^{-2x}} \\
\frac{1}{f'(x)} = \frac{1 + 2e^{-x} + e^{-2x}}{e^{-x}} = \frac{1 + e^{-2x}}{e^{-x}} + 2 = 2\cosh(x) + 2$$

@Jasper Not a bad idea! :P
Anilla
Anilla
Is there some sort of test I can use between a function and its derivative to determine if the derivative is indeed a derivative?
Jasper
Jasper
@Anilla Yes. Simply differentiate the function to check that the derivative is correct! But maybe that is not what you mean...
El'endia Starman
El'endia Starman
@Jasper ...this is literally what I did to answer Anilla's question...
Jasper
Jasper
19:35
Yes. There is no other way.
El'endia Starman
El'endia Starman
But another way to sorta do it is to calculate (f(x + reallysmallamount) - f(x)) / reallysmallamount and compare it with f'(x).
Jasper
Jasper
That's a heuristic justification, something like that.
Anilla
Anilla
@El'endiaStarman Oooo that's what I was looking for :)
El'endia Starman
El'endia Starman
Yeah, if they're way off then you either did something wrong or your function is crazy.
Anilla
Anilla
Thanks ya'll! Sorry my understanding is a bit naive hehe, I really appreciate it :)
Jasper
Jasper
19:37
@Anilla That would give us an idea of why the answer might be correct, but not really prove that the answer is correct.
El'endia Starman
El'endia Starman
@Anilla No problem. :)
Anilla
Anilla
@Jasper I don't necessarily wanna prove its correct, just see if it's close enough.
Jasper
Jasper
@Anilla Aha! Which is why it is important for us to understand what your question was really asking for. But yeah I think we have said in total all the important things already.

19:42
@El'endiaStarman I WANT TO TALK ABOUT ALL OF THE SPOILERS! xD
El'endia Starman
El'endia Starman
@Anilla It may be worth finding out how your chosen language actually calculates cosh. If it's by way of one of the identities using exp(), then you may be better off using a form that uses exp instead of cosh.
Anilla
Anilla
@El'endiaStarman Yea, that's what I need to test. If it's just defined like the actual cosh function and not using a table or some sort of programmatically optimized algorithm, then it wouldn't be worth it.
Jasper
Jasper
Oh I know nothing about programming, hehe.
