Yes, I have recognized this to be a problem, but, it is less of a problem than
the other problems I have at the moment. Currently, there are very few machines
that are capable of being attached to a human being and have their blood sugars
read and stored at the intervals I would require. Most of them are in
development and have not been released to the public. The data from these
machines is very well guarded by the developers of those machines, presumably
for trade secret reasons. As such, I cannot simply ask someone for their minute
by minute data and have them give it to me. The second problem is one of
money. I'm sure if I threw money at the companies, they'd give me some data to
work with, but I don't have any money. I'm doing this purely for personal use
at the moment.
So, the best I can do right now is get some data and attempt to guess at the
blood glucose readings between the actual readings I have. I *know* that the
training fo the nnet will be tainted by the "synthetic" nature of the output,
but there's not much I can do about that right now. If I show it is possible to
train a neural net to accomplish this with the "synthetic data", which probably
won't be that far off from the real readings, then I can use that as leverage to
try it with real data.
Thank you for your advice, and it is something that I have thought of, but
unfortunately there is no way around this problem at the moment that I can think
of. However, if you have any ideas in that regard, I'd be very interested to
hear them.
