Stateful vs. Stateless LSTMs

Why is this so important at this point in time?
This is why we have to decide already now, in the beginning, which one we are going to use.
And to decide this, we will briefly show what is the difference between stateless and stateful LSTM.
As you probably know, LSTM is meaning Long Short-Term Memory. So this neuronal network manages short-term memory.
And this is the main difference between stateless and stateful LSTMs.
In a stateless mode, LSTM updates parameters on batch one, let's say batch one.
