I’m trying to reproduce the results from this Tensorflow tutorial: Neural networks curve fitting | Lulu's blog Simple curve fitting with neural network / deep learning. Example, details and explanation of multi-layer neural-network nonlinear regression with TensorFlow. …

One important typo, your loss function is evaluating x vs y with no intervening model, leading to the nice line you get. Try loss(x, y) = Flux.Losses.mse(approx(x)', y) And two less important differences. Keras uses a batch size of 32 by default , Flux.DataLoader does not batch unless you ask. t…

Urgh. I knew I was missing something obvious. Of course Flux can only train the network if the loss function actually depends on the network parameters…
Thank you very much for taking a look and helping out!
