Landslide susceptibility evaluation can accurately predict the spatial distribution of potential landslides, which offers great usefulness for disaster prevention, reduction, and land resource management. Aiming at problems insufficient samples landslide compilation, difficulty in expanding samples, expression nonlinear relationships among factors, this paper proposes a new method combining deep autoencoder multi-scale residual network (DAE-MRCNN).

Urban vitality serves as a crucial metric for evaluating sustainable urban development and the well-being of residents. Existing studies have predominantly focused on analyzing direct effects intensity (VI) its influencing factors, while paying less attention to diversity (VD) indirect impact mechanisms. Supported by multisource remote sensing data, this study establishes five-dimensional evaluation system employs Partial Least Squares Structural Equation Model (PLS-SEM) quantify...
Effective landslide disaster risk management contributes to sustainable development. A useful method for emergency and avoidance is Landslide Susceptibility Mapping (LSM). The statistical susceptibility prediction model based on slope unit ignores the re-lationship between triggering factors spatial characteristics. It disregards influence of adjacent image elements around slope-unit element. Therefore, this paper proposes a hardwired kernels-3DCNN approach LSMs considering spatial-factor...
To capture both global stationarity and spatiotemporal non-stationarity, a novel mixed geographically temporally weighted regression (MGTWR) model accounting for local effects in space time is presented. Since the constant spatial-temporal varying coefficients could not be estimated one step, two-stage least squares estimation introduced to calibrate model. Both simulations real-world datasets are used test verify performance of proposed MGTWR Additionally, an Akaike Information Criterion...
Geological disaster risk assessment can quantitatively assess the of disasters to hazard-bearing bodies. Visualizing geological provide scientific references for regional engineering construction, urban planning, and prevention mitigation. There are some problems in current binary classification landslide model, such as a single sample type, slow multiclass speed, large differences number positive negative samples, errors results. This paper introduces multilevel hazard scale selects...

Point-of-interest (POI) recommendation is one of the fundamental tasks for location-based social networks (LBSNs). Some existing methods are mostly based on collaborative filtering (CF), Markov chain (MC) and recurrent neural network (RNN). However, it difficult to capture dynamic user’s preferences using CF methods. MC suffer from strong independence assumptions. RNN still in early stage incorporating spatiotemporal context information, main behavioral intention current sequence not...
Previous studies have demonstrated that non-Euclidean distance metrics can improve model fit in the geographically weighted regression (GWR) model. However, GWR often considers spatial nonstationarity and does not address variations local temporal issues. Therefore, this paper explores a (GTWR) approach accounts for both simultaneously to estimate house prices based on travel time metrics. Using price data collected between 1980 2016, response explanatory variables are then modeled using...
As urban development accelerates and natural disasters occur more frequently, the urgency of developing effective emergency shelter planning strategies intensifies. The location selection method under traditional multi-criteria decision-making framework suffers from issues such as strong subjectivity insufficient data support. Artificial intelligence offers a robust data-driven approach for site selection; however, many methods neglect spatial relationships targets within geographical space....
Landslide susceptibility mapping (LSM) is an important decision basis for regional landslide hazard risk management, territorial spatial planning and making. The current convolutional neural network (CNN)-based models do not adequately take into account the nature of texture features, vision transformer (ViT)-based LSM have high requirements amount training data. In this study, we overcome shortcomings CNN ViT by fusing these two deep learning (bottleneck (BoTNet) (ConViT)), fused model was...

Point-of-interest (POI) recommendation is the prevalent personalized service in location-based social networks (LBSNs). A single use of matrix factorization (MF) or deep neural cannot effectively capture complex structure user–POI interactions.
