## 2 Material and Methods  
### Dataset Employed  
The admixture properties, materials and the detail of obtained datasets were given from [PERSON] et al. [4]. Here, a summary of the dataset used in this study was presented. The materials used to conduct SCC are ordinary Portland cement (C) CEMI 52.5 N; class F FA, SF, and LP were used as cementing and filler materials. The physical and chemical properties of C, FA, LP, SF are presented in Table 1. SP of polycarboxylate, ASTM C494 Type F, was utilized in the admixture contents. The CG and FG were designed based on BS EN 12620, and that comprise a crushed dolomite size 12.5 mm and natural sand with 2.975 fineness modulus for the CG and FG, respectively [4]. The mix preparation was designed based on six independent variables that focused on the percentage of total powder (P) content of the admixture. FA, SF, and LP were replaced the cement by mass of total powered material. The percentage of FG/CG was selected constant for all cases. The control sample of SCC admixture was designed to attain 680 mm and 44.3 MPa for slump flow diameter and 28-day compressive strength, respectively; the mix ingredients of the control mixture is presented in Table 2[4]. The experimental preparation and tests were presented in [PERSON] et al. [4]; a cone (300 mm high, 100 mm and 200 mm of upper and lower diameters, respectively) was used to measure the slump flow, and a hydraulic machine test (capacity and accuracy 200 tons and 0.5 ton, respectively) was utilized to extract the compressive strength of 100 mm cubes after 28 days. The total number of experiments was calculated using an equation and designed codes ranges, more details can be found in [PERSON] et al. [4]. In the current study, eight variables are considered as input variables to estimate S and CS of SCC. Table 3 illustrates the input and output variables range. From the table, it can be seen that there is a variety of range in the input variables; the maximum ranges were observed in the powered contents, C, FA, LP, and SF. This means that the powdered contents are a significant function that could be affected the SCC properties, S and CS, besides the main variables of concrete, W, CG, and FG. \begin{table}
