Bug: KNN graph construction mishandles exact duplicate feature rows
Bug: KNN graph construction mishandles exact duplicate feature rows: a task in LegoFlow-SWE (Harbor dataset). When features contain rows that are exact duplicates of one another, the KNN graph constructed from those features does not guarantee that duplicate rows appear as mutual nearest neighbors…
The task
When features contain rows that are exact duplicates of one another, the KNN graph constructed from those features does not guarantee that duplicate rows appear as mutual nearest neighbors with zero distance. This leads to incorrect distances and neighbor indices, which can distort downstream analysis (e.g., outlier…
