چکیده

Deformation of ground during tunnelling projects is one the complex issues that required to be monitored carefully avoid unexpected damages and human losses. Accurate prediction settlement (GS) a crucial concern for problems, adequate predictive model can vital tool tunnel designers simulate accurately. This study proposes relatively new hybrid artificial intelligence (AI) models predict earth pressure balance (EPB) shield in Bangkok MRTA project. The were various nature-inspired frameworks, such as differential evolution (DE), particle swarm optimization (PSO), genetic algorithm (GA), ant colony optimizer (ACO) tune adaptive neuro-fuzzy inference system (ANFIS). To obtain accurate reliable results, modeling procedure established based on four different dataset scenarios including (i) preprocessed normalized (PPN), (ii) nonnormalized (PPNN), (iii) non-preprocessed (NPN), (iv) (NPNN) datasets. Results indicated PPN scenario significantly affected terms their perdition accuracy. Among all developed models, ANOFS-PSO achieved best predictability performance. In quantitative terms, PPN-ANFIS-PSO attained least root mean square error value (RMSE) 7.98 correlation coefficient (CC) 0.83. Overall, results confirmed superiority explored AI robust tunnelling.

Prediction of toxicity of aliphatic carboxylic acids using adaptive neuro-fuzzy inference system

Toxicity of 38 aliphatic carboxylic acids was studied using non-linear quantitative structure-toxicityrelationship (QSTR) models. The adaptive neuro-fuzzy inference system (ANFIS) was used to construct thenonlinear QSTR models in all stages of study. Two ANFIS models were developed based upon differentsubsets of descriptors. The first one used log ow K and LUMO E as inputs and had good predicti...

Prediction of slope stability using adaptive neuro-fuzzy inference system based on clustering methods

Slope stability analysis is an enduring research topic in the engineering and academic sectors. Accurate prediction of the factor of safety (FOS) of slopes, their stability, and their performance is not an easy task. In this work, the adaptive neuro-fuzzy inference system (ANFIS) was utilized to build an estimation model for the prediction of FOS. Three ANFIS models were implemented including g...
