Research Type Theoretical We identify two properties of hierarchical algorithms, and prove that linkagebased algorithms are the only ones that satisfy both of these properties. Our characterization clearly delineates the difference between linkage-based algorithms and other hierarchical methods. We formulate an intuitive notion of locality of a hierarchical algorithm that distinguishes between linkage-based and global hierarchical algorithms like bisecting k-means, and prove that popular divisive hierarchical algorithms produce clusterings that cannot be produced by any linkage-based algorithm.

Pseudocode No The paper describes algorithms conceptually through definitions and properties but does not contain any structured pseudocode or algorithm blocks.
Open Source Code No The paper is a theoretical work focusing on characterization and proofs, and does not mention the release of any source code or provide links to repositories.
Open Datasets No The paper defines 'data sets' as theoretical constructs (X, d) for its mathematical framework, but it does not utilize or refer to any specific publicly available datasets for experimental evaluation.
Dataset Splits No The paper is theoretical and does not perform experiments on datasets, therefore it does not discuss training/test/validation dataset splits.
Hardware Specification No The paper presents a theoretical characterization of hierarchical clustering algorithms and does not involve any experimental evaluations, hence no hardware specifications are provided.
Software Dependencies No The paper is entirely theoretical and does not describe any implementation or experimental setup that would require specific software dependencies with version numbers.
Experiment Setup No The paper focuses on theoretical characterization and proofs, and does not include any experimental evaluations or specific experimental setup details such as hyperparameters or training configurations.
