Data Mining of the Thermal Performance of Cool-Pipes in Massive Concrete via In Situ Monitoring

Algorithm 1

Grid-search 𝑉-fold CV method.

(1) Create mesh grid of 𝜀,𝐶,𝛾.

(2) for 𝑖,𝑗,𝑘 in the searching grid do

(3)      for 𝑚=1 to 𝑉 do

(4)        make 𝑆_𝑚 as the testing data set, and 𝑆_𝑖(𝑖=1,…,𝑚−1,𝑚+1,…,𝑛) as the training data set

(5)        do SVM with parameters of (𝜀_𝑖,𝐶_𝑗,𝛾_𝑘), calculate the accuracy as 𝑎_𝑚

(6)      end loop 𝑚

(7)      obtain the highest 𝑎_𝑚, and record it as 𝐴_𝑖𝑗𝑘

(8) end loop 𝑖,𝑗,𝑘

(9) obtain the highest 𝐴_𝑖𝑗𝑘
