A Spark-based implementation of Adam and AdaGrad optimizer, methods for Stochastic Optimization. See https://arxiv.org/abs/1412.6980 and http://www.jmlr.org/papers/volume12/duchi11a/duchi11a.pdf Comparing with SGD, Adam and AdaGrad have better performance. Especially in case of sparse features, Adam can converge faster than normal SGD.
After getting Spark build environment ready, run 'sbt package' under the root of the source to build the package then excute '$SPARKHOME/bin/spark-submit
--class TestAdaOptimizer
--master local[*] target/scala-2.10/spark-adaoptimizer_2.10-0.0.1.jar'
“Some APIs are not found or parameters not match”
Please modify the settings in build.sbt to match your environments.
