Hi all,

I have a liitle problem with creating my train data to trainNetrwok. I have much files which is build with data position, velocity, acceleration( x,y,z,vx,vy,vz,ax,ay, az). I crated also a columns with datas matching when my quadrocopter is flying and when is falling. My goal is get the moment when my quadracopter is falling. How can I create my network with data and output like : 'fly' and 'fall'.

In addition, I crated a network with my data but xtrain is a cells with data and ytrain is a categorical with fly and fall but network show generalized classyfication, not moment when my quadrocopter is falling.

Thanks for help :)

From your description I believe you are trying to train a model on a timeseries of sensor data points and you wish to get a binary classification of "fly" or "fall" representing "pass" and "fail" for your quadcopter respectively. You may be facing issues with one of the following:

The way the training data is being fed into the trainNetwork function, or
The network's last layer, or
Post-processing of the network outputs

More information is needed here. I would recommend creating a case and describing the issue to our Tech Support team for correct next steps. You can create a case with them here:
