Notice: The reproducibility variables underlying each score are classified using an automated LLM-based pipeline, validated against a manually labeled dataset. LLM-based classification introduces uncertainty and potential bias; scores should be interpreted as estimates. Full accuracy metrics and methodology are described in Coakley et alK. L. Coakley, T. Snelleman, H. Hoos, and O. E. Gundersen, "The embrace of open science: An analysis of a decade of AI research and 56 800 conference papers," Under Review, 2026..

| Pseudocode | Yes | Algorithm 1 DBSCAN |
| Open Source Code | Yes | Our code is available at https://github.com/Ninh Pham/s Dbscan. |
| Open Datasets | Yes | We conduct experiments on three popular data sets: Mnist (n = 70, 000, d = 784, # clusters = 10), Pamap2 (n = 1, 770, 131, d = 51, # clusters = 18), and Mnist8m (n = 8, 100, 000, d = 784, # clusters = 10). |
| Dataset Splits | No | We conduct experiments on three popular data sets: Mnist (n = 70, 000, d = 784, # clusters = 10), Pamap2 (n = 1, 770, 131, d = 51, # clusters = 18), and Mnist8m (n = 8, 100, 000, d = 784, # clusters = 10). |
| Hardware Specification | Yes | We conducted experiments on Ubuntu 20.04.4 with an AMD Ryzen Threadripper 3970X 2.2GHz 32-core processor (64 threads) with 128GB of DRAM. |
| Software Dependencies | Yes | We implement s DBSCAN and s OPTICS in C++ and compile with g++ -O3 -std=c++17 -fopenmp -march=native. We use the Eigen library 2 for SIMD vectorization on computing the distances. |
| Experiment Setup | Yes | Parameter settings. We consider min Pts = 50 for all experiments. s DBSCAN and s OPTICS use D = 1024, m = min Pts. Randomized kernel embeddings use σ = 2ε, d = 1024. We use k = 5 for Mnist and k = 10 for Pamap2 and Mnist8m. |
