I am working on a problem similar to this one:(supervised, artificial data)
x=np.random.uniform(-100,100,10000) y=np.random.uniform(-100,100,10000) z=np.random.uniform(-100,100,10000) a=np.random.uniform(-100,100,10000) b=np.random.uniform(-100,100,10000) i= x**2/1000 + 2*x*y/1000 + 4*np.sqrt(abs(z)) + z*a + 4*a + abs(b)**1.5 -1/((b+1)**2) * a + 10*y
Since I am not creating the data myself I want to make sure, that my customer provided all the relevant input features. Is there a way to find out, whether the input is complete and not lacking a feature, say "a"? Obviously if the input is the same and the output differs it would be evidence of missing data but it isn't guaranteed that any two input samples are the same. Another way I thought of would be to use an autoencoder to find the dimension of the dataset(including the output) and hope it is exactly the input dimension but in my case it is also possible that there are redundant features. Is there any other way to check whether a function is computable from the given inputs?
