The coils obtained with the near-axis expansion optimization are shown in (b). WebL-BFGS. L-BFGS is currently only a low-level optimization primitive in MLlib. If you want to use L-BFGS in various ML algorithms such as Linear Regression, and Logistic Regression, you have to pass the gradient of objective function, and updater into optimizer yourself instead of using the training APIs like LogisticRegressionWithSGD.
