MATLAB LSTM chickenpox example is the only working case

Hi,

I'm studying LSTM networks forecasting, looking at the chickenpox example on MATLAB website, I've learned how to perform a multistep forecasting of time series.

I applied those concepts to a simple sin function time history and it worked, then I used another time history, similar to the chickenpox cases one, give by MATLAB and the forecasting didn't worked.

Even modifying the lstm layer properties or the training options. I tried also to modify the architecture. It simply doesn't work.

The "predicting" is working properly but "forecasting" is only working on that specific time series given for the example.

I attach the test time history I'm trying to forecast, the result is a line or at maximum a sinusoidal shape, not reproducing all the peaks of the original time history.

Hi, how does your data looks like? Is it similar as the chicken pox example where it is just one row with multiple columns ?
