Question

I'm writing my Bachelor Thesis within the field of neural networks and I need some preparation of the data I'm using. Do you have an idea how I am able to identify the four levels in this graph via machine learning? Especially changing points are of importance for me. In this case it would be the x-values roundabout 2700, 3700 and 4700. I already thought of Clustering, but since I'm interested of the different levels, this does not quite work out.

Thankyou, Lukas

@nbro The cluster methods I used, did not work. For example k-means.. Do you have a cluster method in mind, that could work? — lukas_ben, Jan 20 '19 at 23:24

Search for "change point detection" and "change in mean" and you will find various classic textbooks and surveys on this.
