Separate regions based on slope.

[rk1989]

Hello there,

My maths is not good, I have this little problem i would like to solve.

in this figure you see two regions in separate circles.
based on those slope of points what mathematical method should i use to differentiate between those two regions?
If i apply that method on data i can distinguish region 1 and region 2.
Lengths and height of regions can vary.

thank you.

What do you mean, mathematically, by "regions"?

Each pair of points has its own slope. Which points and slopes do you mean? What do you mean by "differentiating" between the regions?

If i apply that method on data i can distinguish region 1 and region 2.
Lengths and height of regions can vary.

Please reply with the full and exact text of the exercise, the complete instructions, and a clear listing of your efforts so far. This information will go a long way toward explaining (to us) what is going on here. Thank you!

if you look there is a pattern you see in the line passing through points in region 1, that means it is beginning of some event, likewise in region 2 there is no pattern like the region 1 pattern, that means the event which started in region 1 continues and there will be some region 3 where the line will fall (just opposite of region 1) that will be end of that event.

like supervised learning or something in machine learning methods.

it's not from any exercise. you can imagine data as heights of points from horizontal line/x-axis.

Something i have to add to previous reply -
So we just have to find out region 1 where event started and region 3
that event hasn't ended up until region 3 no matter how many times line drops back to zero

I'm sorry, but I have no idea what you mean by this. Perhaps somebody else can make sense of it, and reply with assistance.
