viirya commented on issue #26722: [SPARK-24666][ML] Fix infinity vectors produced by Word2Vec when numIterations are large URL: https://github.com/apache/spark/pull/26722#issuecomment-560274676 The above alpha value looks normal, when infinity values appear. For now it looks like we continue adding weights from partitions iteratively, until it is too positive/negative to hold in float. Thus increasing partitions can cause it, also increasing iteration can too.
