[D] Can I share a model trained on a non free dataset ? • r/MachineLearning

The difference is that JPEG and MP3 aren't trained codings: they are fixed codings. Also, one thing is the JPEG algorithm and its coefficients (e.g. Used that way, a neural network is not really distinct, it's just a bunch of coefficients that can be used to reconstruct the pixels/PCM values, etc. to reproduce media. But neural networks aren't used that way, unless you are talking about an autoencoder. If I train a classification network on a certain dataset, there isn't any way of recovering the dataset from the trained coefficients of the network... in fact, it might not even be possible to say which dataset(s) I used to train the network.
