I have sensors placed in pipelines and I have amplitudes coming from it. I want to detect the type of activity taking place at the sensors(like digging,tunneling,clamping etc). So I have a signal which consists of 30 amplitudes, what features can i extract.
What are the assumptions that I have to make(like the signal should be stationary etc). Is my signal stationary in this case.If it is not can I apply frequency domain features.What are the differnt features I can use apart from mean,median,mode,skewness,kurtosis etc.I am trying t build a nueral network classifier.Is not my signal continous if it comes each second(amplitudes).Can I apply fourier tranform here.
Sorry I am a complete newbie in the field
