Summary: Implement the Orthant-wise Limited Memory QuasiNewton optimization algorithm, a variant of L-BFGS that handles L1 regularization
Key: FLINK-1965

https://issues.apache.org/jira/browse/FLINK-1965 Project: Flink
Issue Type: Wish
Components: Machine Learning Library
Reporter: Theodore Vasiloudis
Priority: Minor
The Orthant-wise Limited Memory QuasiNewton (OWL-QN) is a quasi-Newton optimization method similar to L-BFGS that can handle L1 regularization.
Implementing this would allow us to obtain sparse solutions while at the same time having the convergence benefits of a quasi-Newton method, when compared to stochastic gradient descent.
