comment Biasing sigmoid curve
Lets say 'c = 10', which is where I want $y$ to be almost $0$. I was imagining the S shape to skew a little upwards such that $f(5) > 0.5$ (for fit values). But I guess your approach is good too. It still promotes fit values a bit more than the average, and unfit less.

comment Biasing sigmoid curve
The power approach seems to squash the sigmoid to the left if $a > 1$, and stretch it to the right if $a < 1$. I was thinking more on the lines of changing the S shape such that its skewed upwards, however your idea might have a good effect too. +1

comment Math notation for summing up the rows in a matrix
Thanks. Seems that this is the 'standard' way then...

comment Function with a continuous domain but a discrete range
So in my case, am I correct to say that it is not a continuous function? And the definition of it can still be: $lights: \Bbb R_{\geq0} \rightarrow \{0,1\}$

comment Function with a continuous domain but a discrete range
Yes, its those kinds of issues I am asking about. In the example I gave, if the function was $lights(t)$, $t$ is definitely a continuous value, but at the same time the result is just 0 or 1. So is it a continuous function or not? Or does it have a specific name? And how is it defined (do you put $lim$ etc.)?

comment Function with a continuous domain but a discrete range
Yes, what I mean is, does it have a specific name? Is it defined in a specific way? It is not a continuous function, so I don't think it is defined using limits, or is it?

comment What would be the right domain for a function that takes time as a parameter?
Yes precisely what I am trying to model. Thanks

comment What would be the right domain for a function that takes time as a parameter?
Yes, no need for complex numbers. I just wanted to know what is the most common way people use to represent a normal timeline

So is it defined as something like $T$ and specified that $T \subset R$? Or is there a specific standard symbol?
