Which neural network to choose to determine the strength of the trend?

Question

Neural networks

Friends tell me which neural network can be chosen to determine the trend of the graph?
I have two variables X - the value plotted on the graph and Y - some variable that correlates with X
Let's say X is temperature and Y is atmospheric pressure.
I need to determine the strength of the trend at a particular point in time. Ascending or descending.
Chart example:

1. Weak uptrend
   
2. Strong uptrend
   
3. Weak uptrend
   
4. Weak downtrend
   
5. Strong downtrend
   

Yes - I don’t need to approximate anything (I don’t need to make any forecasts for the future)
I just need to determine the strength of the trend, and that’s it, tell me which neural network (architecture) is best suited for this task?

Answer 1

Have you all gone crazy with these networks? You have a function graph, what you call "trends" - this is called in mathematics "the tangent of the slope of the tangent to the function graph at a point." It is also “the derivative of a function at a point”, it is also “the geometric meaning of the differential of a function”.
