yunfengzhou-hub opened a new pull request #70: URL: https://github.com/apache/flink-ml/pull/70
## What is the purpose of the change This PR adds Estimator and Transformer for the Streaming KMeans operator. Compared with the existing KMeans operator, Streaming KMeans allows to train KMeans model continuously from an unbounded train data stream. The corresponding Model operator also supports updating model data dynamically from a DataStream. Besides, this PR also adds simple infrastructures needed to test online algorithms, which allows to control the order to consume train data and predict data. ## Brief change log - Adds `StreamingKMeans`, `StreamingKMeansModel` and `StreamingKMeansParams` class to support Streaming KMeans algorithm. Also adds `StreamingKMeansTest` class to test these classes. - Adds `HasBatchStrategy` and `HasDecayFactor` interfaces to represent corresponding parameters for online algorithms. - Adds `MockBlockingQueueSinkFunction`, `MockBlockingQueueSourceFunction` and `TestBlockingQueueManager` to control the stream's velocity in online algorithm's test cases. ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (no) - The public API, i.e., is any changed class annotated with @public(Evolving): (no) - Does this pull request introduce a new feature? (yes) - If yes, how is the feature documented? (Java doc) -- This is an automated message from the Apache Git Service.
