Worked on the SciPy repository to deliver a targeted fix for the Yule distance metric in the spatial.distance module, addressing a correctness issue in the C implementation within distance_metrics.h. The approach involved aligning the C code’s behavior with both the previous implementation and the Python version, ensuring consistent results across languages for clustering and similarity analyses. To validate the solution, a dedicated regression test was added, strengthening the module’s reliability. The work drew on skills in algorithm implementation, numerical computing, and testing, utilizing both C++ and Python to maintain robust, cross-language distance computations in a widely used scientific library.
