Reply to comment by iCameToLearnSomeCode in [P] How to reverse engineer a neural network to get inputs from the outputs by ojiber

I had thought of this but unfortunately, I don't think that I have enough information in my output variables to be able to predict the inputs. When reversing the network the error bounces around and my accuracy stays consistently at ~10%.

You’ll never get an accurate input reconstruction.

The whole goal of a model is to estimate an output from an input. The best you can do is estimate an input from an output as well. Neural networks aren’t designed to be "lossless", part of the information is loss but in a way that makes the relevant information to the task preserved.

But the estimated input will simply the value which makes the initial model best fit the label.
