Regionalization is a classification procedure applied to spatial objects with an areal representation, which groups them into homogeneous contiguous regions. This paper presents an efficient method for regionalization. The first step creates a connectivity graph that captures the neighbourhood relationship between the spatial objects. The cost of each edge in the graph is inversely proportional to the similarity between the regions it joins. We summarize the neighbourhood structure by a minimum… 

A framework for spatial regionalization composed of novel clustering‐based algorithms under spatial contiguity constraints

The results showed that the framework presented leads to a faster way of executing regionalization tasks in the experimental analysis, allowing us to observe a significant gain of AHR and RegK‐Means over AZP in execution time, while showing better or similar results in other metrics, such as figure of merit.

Graph Regionalization with Clustering and Partitioning: An Application for Daily Commuting Flows in Albania

The paper presents an original application of the recently proposed spatial data mining method named GraphRECAP on daily commuting flows using 2011 Albanian census data. Its aim is to identify

Regionalization with dynamically constrained agglomerative clustering and partitioning (REDCAP)

This research proposes and evaluates a family of six hierarchical regionalization methods based on three agglomerative clustering approaches, including the single linkage, average linkage (ALK), and the complete linkage (CLK), each of which is constrained with spatial contiguity in two different ways.

Graph Partitioning-Based Clustering for the Planning of Distribution Network Topology using Spatial- Temporal Load Forecasting

Planning the expansion and the new topology of distribution networks requires knowing the location and characterization of the load as well as its future growth. Spatial load forecasting is a key

An Extended Minimum Spanning Tree method for characterizing local urban patterns

This study presents a simple and novel graph-theoretic approach, Extended Minimum Spanning Tree (EMST), to describe and characterize local building patterns at building-unit level for large urban areas and demonstrates that the EMST is an effective data structure for understanding localBuilding patterns from both geographic and perceptual perspectives.

Efficient Algorithms for Regionalization : an Approach Based on Graph Partition

This paper proposes new approaches based on the GRASP and Evolutionary algorithms for the resolution of a specific regionalization problem. This problem can be mapped on a capacity and connectivity

Supervised Spatial Regionalization using the Karhunen-Loève Expansion and Minimum Spanning Trees

The article presents a methodology for supervised regionalization of data on a spatial domain. Defining a spatial process at multiple scales leads to the famous ecological fallacy problem. Here, we

A Generative Spatial Clustering Model for Random Data through Spanning Trees

This work presents a new probabilistic regionalization algorithm that allows spatially varying random variables as features and is able to better accommodate the natural variation of the data and to diminish the effect of outliers, producing better results than state-of-art approaches.

Zone design of specific sizes using adaptive additively weighted Voronoi diagrams

A new method based on a discrete version of the adaptive additively weighted Voronoi diagram that makes it possible to partition a two-dimensional space into zones of specific sizes, taking both the position and the weight of each seed into account.
