|
Proposed a model to predict the shear behaviour of clean rock joints developed by using a multilayer perceptron. A rock slope stability problem was also used as an example for applying the model in practice. |
The developed neural model was able to express the influence of the input variables in the shearing behavior of joints and may be an alternative to the existing analytical models which sometimes require certain parameters obtained from large-scale laboratory tests which are not always available. |

Developed Takagi-Sugeno fuzzy systems for predicting shear strength of clean rock joints incorporating uncertainties in the variables that govern their shear behavior. |
Despite the proposed models present the advantage of considering the uncertainties of their input variables, their responses are still deterministic. |

|
Presented a fuzzy logical decision-making algorithm based on block theory to determine discontinuous rock slope reliability by classifying the slope into expressive classes such as stable or unstable. |
The proposed algorithm is relatively simple, requires low computational cost, has excellent compatibility, provides intuitive and experimental satisfaction and can be used by students and less experienced people. |

|
Investigated the performance of multilayer perceptron, support vector machines, k-nearest neighbors, decision tree and random forest models to predict the soil slope safety factors (FS). |
Slope height, total slope angle, dry density, cohesion and internal friction angle were considered to predict the FS for 70 slopes. Among the five machine learning models, the multilayer perceptron was found to be the most reliable for predicting FS. |

|
Provided a comparative analysis between multilayer perceptron, decision tree, support vector machines and random forest learning algorithms to predict soil slope safety factors, using a dataset of 100 records of slopes. |
The paper tried to fill the gap in traditional analysis procedures based on advanced methods in slope stability assessments. The multilayer perceptron achieved the highest accuracy and precision in predicting the FS. |
