Abstract
Background
Geographical information about human settlements is necessary to facilitate humanitarian aid, recognize the location of real-world objects, support local development and improve disaster resilience in settlements. Although deep learning is employed in object location in settlements, these models have computational complexity and less detection accuracy. Hence they require further development with regards to precision in object location from geographic data.
Objective
To efficiently identify the object location in Chinese settlements from geographic information, we proposed Artificial Neural Network (ANN) optimized by Red Fox (RF) optimization (ANN-RF) model in this research.
Methods
The multi-resolution Geographic information data was collected from Tongzhou District, Beijing, China. ANN applies the measures of length, area, distance and direction to recognize object location from this data. An RF algorithm is used to optimize the weight vector of the ANN architecture to improve the efficiency of the ANN architecture. The parameters such as precision, recall, F1-score, number of correct detections, overall actual matches and the total number of detections were computed for the proposed model.
Results
The precision rate and F1-score for the proposed ANN based RF optimization are about 98.9% and 97.5% which are higher than that of conventional models.
Conclusion
The proposed ANN-RF model shows promising results in detecting object location in settlements from geographic information.

1 Introduction
A rural settlement is a countries’ environment type in which the people live and engage in production, which results from local interactions with natural, social, economic, and cultural environments (Yang et al., 2015). It provides places to live and work in the rural side (Li and Song, 2020). Geographic Information Systems (GIS) is used in various fields nowadays, which provide a fastcontrast of complex databases and support for entirely new analytical forms. Archeological GIS studies have proliferated over the past three decades (González-Tennant, 2016). Many individually developed technologies are increasingly used to support the comprehension, education, prediction, and decision-making of spatial events. These contain remote sensing and photogrammetry, digital imaging, object recognition, Artificial Intelligence, etc., which can be called spatial information technology. Most of the integrated systems are slowly becoming available as a basic technology integrated with the GIS, data manager, and other systems. The examination is done in the technologies’ potential role of many of the spatial decision support which mainly focuses on decision-making in urban contexts, especially in informal settlements (Mason et al., 1997) (Table 1).

Settlement aggregation refers to the process of human migration, which contains two parts from different perspectives. From a social point of view, it is the process of creating a community for the people. From the point of view of physical form, it is a process by which natural or artificial elements form a physical settlement with its adjacent environment (Du and Chan, 2019). The matching algorithm is used to find the land/area is changed or not at a certain year of difference (Wang et al., 2015). The conventional methods involved in object and site detection from geographic information system (GIS) is explained below. The existing techniques using Back Propagation Neural Network (BPNN) was capable of detecting the damaged location and extent accurately (Chen et al., 2020). Here the applicability is affected by the computer characteristics variation such as noise measurement, damaged location, vehicle load, and speed. To overcome this, BPNN is used in the detection of damage to a bridge based on the statistical features of dynamic responses (Shu et al., 2013). But the recognition accuracy of the landslide detection by BPNN from spatial image must be improved. Díaz and Soares (2022) developed a selection device using the Analytical hierarchical process (AHP) for coastal wind farms combined with geographical information systems and multiple criterion analysis. A GIS-based model using interval type-2 fuzzy analytic hierarchy process (FAHP) is proposed by Ayodele et al. (2018) for the selection of suitable wind farm site in Nigeria. Zabihi et al. (2020) integrated GIS with a FAHP to evaluate the relative importance of physical, natural, environmental, and socio-economic factors for determining the suitability of ecotourism sites. Haidara et al. (2019) employed FAHP for detecting the location of soil erosion and Ali and Ahmad (2020) for recognizing the suitable landfill site. Eroğlu (2021) and Islam et al. (2020) analyzed to find suitable sites for the disposal of Metropolitan Solid Waste (MeSW) with the combination of FAHP technology and spatial information technology. Roth et al. (2017) proposed a multi-scale approach and holistic framework that provides information about the development process of land settlement projects and sustainability assessment with the comparison between EI Hierro hydro-wind power plant and sivens dam projects. FAHP require multiple factors for detecting suitable locations.
Deveci et al. (2021) utilized a new hybrid approach integrating Interval Rough Numbers (IRNs) into Best-Worst Method (BWM) to choose the best offshore wind farm site in Turkey. Taking disaster’s uncertain and subjective characters into consideration from GIS, IRN is utilized by Song et al. (2019). But IRN needs complex characteristic aggregation and arithmetic operators to identify the location in settlement. Integration of IRN would empower decision-makers in waste treatment organizations to express their judgments within an interval range to overcome indeterminacy in uncertain geographic information (Torkayesh et al., 2021). Yazdani et al. (2020) introduced a new IRN Dombi-Bonferroni (IRNDBM), as an approximate data processing operator due to the lack of accurate information, for site planning for the sanitary waste disposal. Zhang et al. (2018) suggested object-based Convolutional neural network for land use classification from high resolution images. This does not efficiently identify smaller functional objects like hospitals, supermarkets, etc in settlement.
Artificial Neural Network (ANN) has promising results in location prediction. But the number of neurons in the Artificial Neural Network architecture often leads to poor approximation and overfitting issues (Urda et al., 2021; Bejani and Ghatee, 2021). Optimization of the weight vector is also necessary to yield a better fitness value (Dani et al., 2021; Li, 2021; Mao et al., 2021) and to overcome this issue we are using a red fox (RF) optimized Artificial Neural Network to optimize the weights of the ANN architecture. The main objective of this paper is to identify the object location based on multi-resolution geographic information, gathered from Tongzhou District, Beijing, China, using ANN optimized by RF model. The weight vector of the ANN architecture was optimized by RF optimization technique to improve the efficiency of the ANN architecture in object detection from multi-resolution geographic information.
The paper is organized in the following manner. Section 2 gives some related works in the existing literature. Section 3 explains the red fox optimized ANN architecture for GIS object identification. Section 4 shows the experimental results with different performance metrics such as Recall, F1-score, and precision. Finally, section 5 deals with the conclusion.

2.1 Proposed methodology
The proposed methodology relies on ANN optimized RF to recognize the position of objects from the multi-resolution geographic data collected from Tongzhou, Beijing, China provided the multi-resolution geographic data. Initially, similarity between spatial features are determined. ANN learns the spatial features like length, area, distance, and direction from multi-resolution geographic data to predict the location of objects which is the output of ANN. To enhance the the effectiveness of ANN in predicting object location, the weight vector of ANN is optimised using an RF technique. The steps involved in proposed methodology is given in the below sub-section.
2.2 Dataset description
The multi-resolution geographic dataset is obtained from the Tongzhou District of Beijing situated at 36′39°–40°02′N, 116°32′–116°56′ (Song and Li, 2020). The shape of the district is comparatively huge but likely slanted from northwest to southeast. This continent has a monsoon climate along with an average temperature of 11.3 °C annually and a 620 mm rate of average precipitation. To reflect the overall scale characteristics of rural settlements in the Tongzhou District parameters CA and NP are used between them while LPI and MPS reflect the exchange in its structural pattern of rural settlements and LSI reflects asymmetry or problems in the patch shapes of rural settlements. The problem of the shape outside rural settlement patches is represented by SHAPE_MN, which reflects the effects of external activities on the rural settlements. Before the presentation, an integrated, and geometric correction of the images were performed. In keyhole rural settlements, satellite images are displayed in a variety of colors, such as graphics closely linked by many small rectangles. Settlements are displayed in a white tone, with green vegetation interspersed. With these features as attributes, it is possible to extract the rural settlements of Tongzhou.

2.5 Red fox optimization algorithm
The red fox population involves two important phases: (1) leaving well-defined territory and (2) leading nomadic life. The single territory is shared with each herd under the alpha couple hierarchy. After the growth of young ones, they move away from the herd and create another territory. Else, at one day, they occupy the territory of alpha couples. The mathematical formulation of the hunting behavior of red fox is described in the following steps.
2.5.1 Step 1: Global search
All the foxes in the herd should play a role in searching of food for the survival of each herd member. When there is a lack of food in the local region, the herd must be moved to remote locations. The collected information about the explored land is communicated with family members for survival. Based on the individual fitness, the search space is explored and the mathematical expression of the searching process is delineated in the following equations.
The terms and represents the total fox population with iteration × and the best individual in the population with iteration x.
2.5.2 Step 2: Local search
When the prey is visible to red fox, the immediate response of hunting takes place. Initially, they encircle the prey and stay down and hide before hunting (Zhang et al., 2021). Then they attack the prey suddenly or by surprise. The individual movement
distinguishes the fox action as
denotes the closer movement of red fox and
signifies the hiding behavior of red fox. In addition to this, the vision radii
of red fox are determined using the below equations.
The term signifies the scaling parameter which ranges between 0 and 0.2, is the observation angle of fox and denotes the random number lies between 0 and 1.
2.5.3 Step 3: Generation and moving away from the herd
Many hazardous situations such as fox hunting by humans and lack of prey in local territory make the red fox population depart from their own territory. In such a case, some foxes may die and some migrate to the remote destination (Połap and Woźniak, 2021). The mathematical expression of center of habitat
, Euclidean distance
and reproduction of new individual are given as follows,

2.6 ANN based RF algorithm for object location detection from geographic information
Fig. 1 explains the proposed ANN-RF model for object location detection from geographic information. Here, we concentrated both forward matching and backward matching. A characteristic of many full dataset contains no correlation in the low described dataset in the situation of 1:0, which is identical to 0:1 in matching of backward. A feature in the low described dataset contains no correlation in the many described dataset in the case of 1:0, which is identical to 0:1 in forward matching. The neural network met several advantages like ability of parallel processing, good fault tolerance, ability to train machine, distributed memory, store information on the entire network and etc. But, it met few shortcomings in terms of computational complexity, poor detection accuracy and etc. Hence, we combined and utilized ANN with RF algorithm to provide better object location detection from geographic information.Proposed artificial neural network based red fox optimization algorithm for object location detection.

4 Conclusion
The main aim of this paper is to propose an optimized deep learning method for accurate identification of object location based on geographic information. The optimized deep learning method utilized in this paper is RF optimized ANN architecture to accurately detect object location in Tongzhou, China from multi-resolution representation dataset. We compared the performance of the proposed ANN-RF model with existing models in object detection based on geographic images. ANN-RF model achieved precision of 98.9% and F1-score of 97.5% in object localization based on multi-resolution geographic data. The comparative analysis showed that ANN-RF showed higher precision and F1-score than existing models like IRNDBM, BPNN, IRN, and FAHP techniques. Higher precision and F1-score observed for the proposed method was due to optimization of vector weight of the ANN architecture using the RF algorithm. As a result, the proposed methodology can be adopted for object localization in settlements to facilitate identification of natural calamities and infrastructural damages. The limitations of this research are the lack of computational time requirement analysis for the proposed model in object localization in settlement and the proposed model is evaluated on geographic data collected from single district of China. Hence, in the future, time required for detection of object location from geographic information by ANN-RF model must be determined to prove its computational efficiency. Future work may involve investigating transferability of this method for the object detection in multiple geographical regions.
