> Flink ML add isolationForest algorithm
> --------------------------------------
>
> Key: FLINK-33003
> URL: https://issues.apache.org/jira/browse/FLINK-33003
> Project: Flink
> Issue Type: New Feature
> Components: Library / Machine Learning
> Reporter: zhaozijun
> Priority: Not a Priority
> Labels: ml
>
> I want to use flink solve some problems related to anomaly detection, but
> currently flink ml lacks algorithms related to anomaly detection, so I want
> to add the isolation forest algorithm to library/flink ml. During the
> implementation process, when IterationBody is used, I try to understand the
> implementation of the Kmeans algorithm, and use iterative behavior to
> calculate the center point of the isolation forest algorithm, but in the
> test, I found that when the parallelism > 1, the number of iterations > 1,
> and there will be sometimes succeed sometimes fail (fail to find the
> broadcast variable). Please teachers help me to review and point out my
> problem. Thank you 🙏
