latex end section or sebsection

how can I specify the end of subsection. In my example:

I have a subsection with only 3 rows, but I see the next paragraph also as continuance of the subsection:

\subsection{Kontrolle}
Zur Kontrolle eines physischen Systems werden die Time Series, welche durch Sensoren produziert werden, ebenfalls analysiert, um die besonderen Ereignisse zu entdecken.\\\\
In der Time-Series-Analyse gibt es besondere Herausforderungen. Time Series haben üblicherweise eine enorme Größe. Jeder Zeitpunkt in einer Time Series ist eine Dimension, deswegen haben die Punkte in einer Time Series hohe dimensionale Räume. Z. B.  jeder Punkt in einer Time Series mit der Länge 1000 hat 1000 Dimensionen. Die Bearbeitung solcher Höhen dimensionaler Räume ist nicht einfach, sogar mit Super-Rechner.
Um darüber hinaus eine Time Series zu..


how can I solve this problem?

Related: tex.stackexchange.com/questions/165823/…. a \subsection is a macro, not an environment. What follows is just text. If you need to start a new (sub)section, you have to issue an additional sectioning command. –  Steven B. Segletes May 1 at 11:57
I dont want to begin another subsection, I want to resume my section –  Kaja May 1 at 12:09
why would not the next paragraph be assumed to be something other than part of the same section? if you mean that you want to make sure it starts on the same page, you might end the first paragraph with \par\nobreak. –  barbara beeton May 1 at 12:13
You don't provide enough information to fully understand your problem. If you get what you hope, what visual clues will the reader have that you returned to the prior section? A different indentation, for example? –  Steven B. Segletes May 1 at 12:17
Sorry, I am understanding your post now :) thanks –  Kaja May 1 at 12:24

There is no real typographic tradition for marking going "up" to the parent section, traditional settings (and the latex markup) more or less assume that a section has some material at the start but once it starts subsection that all material will be in (some) subsection. So even if you changed the markup to be something like \begin{subsection}...\end{subsection} so in the source it was unambiguous, it is not clear that your readers would know unless you make the typesetting very explicit.
If Kontrolle was the fourth \item in (say) a description or enumerate list, the paragraph after it would be (or could be) indented, and then the following unindented paragraph would be obviously returning to the main text.
