“…To reduce epistemic uncertainty, we require comprehensive trial-and-error studies of landslide conditioning factors and landslide susceptibility mapping methods. Newer machine learning models have overcome the over-fitting and noise challenges that previously arose during the modeling process, and their goodness-of-fit and performance have improved in comparison to more conventional models [32,33,61,62,107]. Recently, researchers have developed promising new ensemble models that are more powerful than individual models [105].…”

“…Examples of recent proposed and hybrid ensemble models for predicting landslides include ANN, SVM, SVR, and ANFIS integrated with genetic algorithm, particle swarm optimization, and gray wolf optimizer [30,[34][35][36]; alternative decision tree (ADTree) combined with ensemble techniques such as AdaBoost (AB), Random Subspace, MultiBoost, Bagging, and Dagging [24,37]; SVM combined with ensemble techniques [38,39], Naïve Bayes tree coupled with Random Subspace [40], radial basis function ANN combined with Rotation Forest [41], best first decision tree combined with Rotation Forest [42], and Bayesian logistic regression combined with AB, MultiBoost, and Bagging [43]. Hybrid ensemble models also have been successfully used in studies of other hazards, including flooding [44][45][46][47][48], wildfire [34,49], sinkhole formation [50], dust storm [51], drought [52], gully erosion [53][54][55], and land subsidence [56], as well as in other environmental studies, such as land-use planning [57] and groundwater potential mapping [54,[58][59][60][61][62].…”

We used AdaBoost (AB), alternating decision tree (ADTree), and their combination as an ensemble model (AB-ADTree) to spatially predict landslides in the Cameron Highlands, Malaysia. The models were trained with a database of 152 landslides compiled using Synthetic Aperture Radar Interferometry, Google Earth images, and field surveys, and 17 conditioning factors (slope, aspect, elevation, distance to road, distance to river, proximity to fault, road density, river density, normalized difference vegetation index, rainfall, land cover, lithology, soil types, curvature, profile curvature, stream power index, and topographic wetness index). We carried out the validation process using the area under the receiver operating characteristic curve (AUC) and several parametric and non-parametric performance metrics, including positive predictive value, negative predictive value, sensitivity, specificity, accuracy, root mean square error, and the Friedman and Wilcoxon sign rank tests. The AB model (AUC = 0.96) performed better than the ensemble AB-ADTree model (AUC = 0.94) and successfully outperformed the ADTree model (AUC = 0.59) in predicting landslide susceptibility. Our findings provide insights into the development of more efficient and accurate landslide predictive models that can be used by decision makers and land-use managers to mitigate landslide hazards.

“…The data modifications at each iteration of the so-called boosting consist of applying weights to each of the training samples (Pedregosa et al, 2011). The literature shows that GBC and ABC have been successfully used as ensemble methods in the development of GPM maps (Nguyen et al, 2020a;Martínez-Santos and Renard, 2020). Finally, for the ETC algorithm (Geurts et al, 2006), randomization goes a step further in the way splits are computed.…”

Abstract. Groundwater is crucial for domestic supplies in the Sahel, where the strategic importance of aquifers can only be expected to increase in the coming years due to climate change. Groundwater potential mapping is gaining recognition as a valuable tool to underpin water management practices in the region, and hence, to improve water access. This paper presents a machine learning method to map groundwater potential and illustrates it through an application to two regions of Mali. A set of explanatory variables for the presence of groundwater is developed first. Several scaling methods (standardization, normalization, maximum absolute value and min-max scaling) are used to avoid the pitfalls associated with the reclassification of explanatory variables. A number of supervised learning classifiers is then trained and tested on a large borehole database (n = 3,345) in order to find meaningful correlations between the presence or absence of groundwater and the explanatory variables. This process identifies noisy, collinear and counterproductive variables and excludes them from the input dataset. Tree-based algorithms, including the AdaBoost, Gradient Boosting, Random Forest, Decision Tree and Extra Trees classifiers were found to outperform other algorithms on a consistent basis (accuracy > 0.85), whereas maximum absolute value and standardization proved the most efficient methods to scale explanatory variables. Borehole flow rate data is used to calibrate the results beyond standard machine learning metrics, thus adding robustness to the predictions. The southern part of the study area was identified as the better groundwater prospect, which is consistent with the geological and climatic setting. From a methodological standpoint, the outcomes lead to three major conclusions: (1) because there is no aprioristic way to know which algorithm will work better on a given dataset, we advocate the use of a large number of machine learning classifiers, out of which the best are subsequently picked for ensembling; (2) standard machine learning metrics may be of limited value when appraising map outcomes, and should be complemented with hydrogeological indicators whenever possible; and (3) the scaling of the variables helps to minimize bias arising from expert judgement and maintains robust predictive capabilities.

“…One of the popular methods for evaluating the output of landslide susceptibility models is the ROC curve. ROC curve is one of the most common methods for evaluating the performance of methods and algorithms used for spatial modeling [40,41]. e numerical value of the area under the ROC curve (AUC) varies between 0 and 1, which is quantitatively used for the validation and comparison of the models.…”

Landslides are one of the most devastating natural hazards causing huge loss of life and damage to properties and infrastructures and adversely affecting the socioeconomy of the country. Landslides occur in hilly and mountainous areas all over the world. Single, ensemble, and hybrid machine learning (ML) models have been used in landslide studies for better landslide susceptibility mapping and risk management. In the present study, we have used three single ML models, namely, linear discriminant analysis (LDA), logistic regression (LR), and radial basis function network (RBFN), for landslide susceptibility mapping at Pithoragarh district, as these models are easy to apply and so far they have not been used for landslide study in this area. The main objective of this study is to evaluate the performance of these single models for correctly identifying landslide susceptible zones for their further application in other areas. For this, ten important landslide affecting factors, namely, slope, aspect, curvature, elevation, land cover, lithology, geomorphology, distance to rivers, distance to roads, and overburden depth based on the local geoenvironmental conditions, were considered for the modeling. Landslide inventory of past 398 landslide events was used in the development of models. The data of past landslide events (locations) was randomly divided into a 70/30 ratio for training (70%) and validation (30%) of the models. Standard statistical measures, namely, accuracy (ACC), specificity (SPF), sensitivity (SST), positive predictive value (PPV), negative predictive value (NPV), Kappa, root mean square error (RMSE), and area under the receiver operating characteristic curve (AUC), were used to evaluate the performance of the models. Results indicated that the performance of all the models is very good (AUC > 0.90) and that of the LR model is the best (AUC = 0.926). Therefore, these single ML models can be used for the development of accurate landslide susceptibility maps. Our study demonstrated that the single models which are easy to use and can compete with the complex ensemble/hybrid models can be applied for landslide susceptibility mapping in landslide-prone areas.
