    Function Plot Smooth
Click For Summary
SUMMARY

The discussion centers on smoothing the function defined as (x+n)/(x+y+n+m), where x and y are real numbers, and n and m are natural numbers. Participants express confusion regarding the graphing of the function, particularly the use of time (T) as an axis. The primary concern is to mitigate abrupt changes in the function's output at early stages, with suggestions to consider the relationships between the variables over time. The conversation concludes with a focus on how to derive a function F(T) from the original formula.

PREREQUISITES
  • Understanding of mathematical functions and their graphs
  • Familiarity with real numbers and natural numbers
  • Basic knowledge of time-dependent variables in simulations
  • Experience with modeling human decision-making processes
NEXT STEPS
  • Explore techniques for smoothing functions, such as moving averages or spline interpolation
  • Research time-series analysis methods to understand variable relationships over time
  • Learn about function transformation to derive F(T) from the original formula
  • Investigate simulation modeling techniques for human decision-making
USEFUL FOR

This discussion is beneficial for mathematicians, data scientists, and simulation modelers interested in function analysis, particularly those working on smoothing techniques and time-dependent variable modeling.

Hi,
I have the following function, which is computed by: (x+n)/(x+y+n+m),
where x, y are real numbers
n, m are natural numbers

What techniques I can use to smooth the function preventing it to jump up or down at an early stage.

I would appreciate your suggestion.
Thanks

I'm confused, your axis on the bottom is labeled as T, what does that have to do with your function?

I kind of assumed x and y were both inputs into your function, so I'm confused how you graphed it like this in general.

Thank you. T represents the time. It seems that n increases quickly in the early timesteps. I am still thinking of ways to use T in the formula.

You have still not told us what it is that you have graphed.

The graph in post #1 makes no sense given your formula. The labels on the graph are C and T, but the formula appears to be a function of x and y, as well as m and n.

Disregarding the m and n terms for the moment, if you have ##f(x, y) = \frac x {x + y}##, the graph will be a surface in three dimensions, with a discontinuity along the line y = -x.

The formula, as well as the graph, are already smooth within their domain.

Thank you. Yes, I just want to slow down the jump at the beginning.

So please provide the following functions, as you've already been asked:

x(T)
n(T)
y(T)
m(T)

x,n,y,m are variables that are changing over time

You have a plot with them! Show us the funtion that you used to generate the plot please.

I construct the function but not fully sure if it is the best way to put all the variables together. I am building a simulation and trying to model human decisions but my model is very simple. The function is above with the question. x and y represent positive and negative personal experiences. n and m represent positive and negative opinions on social media. I assume the combination of all variables specifies the probability of consumption. Because at the beginning of the simulation, social media has 0 opinions, at step 1, multiple opinions are posted.

You have plotted a function ##F\, : \, \mathbb{R}^+\longrightarrow [0,1]## which means for any value ##T\in \mathbb{R}^+## you plotted a point ##(T,F(T)).## Our question is: What is ##F##? It depends only on ##T##, so how do we get from ##\dfrac{x+n}{x+n+y+m}## to ##F(T)##?

F depends on all x,y,n,m, and T also.

Sigh. Your obfuscations will get you nowhere...

Whatever. If you don't like the first point, then just don't plot it. How's that for a solution?

Ok, thank you. I will look into your suggestion.

Okay. Will close the thread, we seem to have the kind of answer that the OP wanted.
