Description
L-BFGS optimization was a requested feature. This PR offers an
LBFGSFunctionOptimizerthat allows the optimization for loss functions of typeTensor1D => Scalar. This is however still at least one step away from a training optimizer. Any suggestion as to how to wrap theLBFGSFunctionOptimizerinto anLBFGSOptimizerfor training is welcome.Suggestions for test cases and test functions are appreciated as well.
