Description
Hi, is there a way to use tfp.optimizer.lbfgs_minimize as Keras optimizer?
This would be quite useful in certain cases where the loss function is approximately quadratic.
A colleague of mine would very much need it since an autoencoder written in R with negative-binomial loss converges faster than its Keras counterpart.
