Classification of real data taken from different borehole sites in the KG basin and comparison between desired output and actual output from network at different depths. Here, subscripts ‘a’, ‘b’ and ‘c’ in the numerical denote data without gas hydrate, data with gas hydrate and data without knowing gas hydrate at hole KG-10A. Similarly, subscripts ‘m’, ‘n’ and ‘p’ and ‘g’, ‘h’ and ‘k’ in the numerical values denote the same for holes KG-03A and KG-04A, respectively.
