Additional file 1 of Quantitative logging data clustering with hidden Markov model to assist log unit classification

Additional file 1: Figure S1. Clustering results for Site C0001. Three panels represent correlation plots among observable parameters other than depth. Ellipses represent covariance of each cluster. Figure S2. Clustering results for Site ITA. Six panels represent correlation plots among observable parameters other than depth. Ellipses represent covariance of each cluster. Figure S3. Clustering results for Site C0020. Three panels represent correlation plots among observable parameters in principal component domain other than depth. Ellipses represent covariance of each cluster. Figure S4. Clustering results for Site C0020. Three panels represent correlation plots among observable parameters in original logging data domain other than depth. Figure S5. Depth plot of electrical resistivity and clustering results for Site C0001 with different hyper parameters ( $${{\varvec{\beta}}}_{0}, {{\varvec{\upsilon}}}_{0}$$ β 0 , υ 0 ) at K = 13. Ellipses represent covariance of each cluster. Log units previously reported (Expedition 314 Scientists 2009b) are shown on the right and dotted black lines. The original set of hyper parameters shown in the main text (Fig. 4) is the left panel at the central raw. Figure S6. Depth plot of P-wave velocity and clustering results for Site ITA with different hyper parameters ( $${{\varvec{\beta}}}_{0},{{\varvec{\upsilon}}}_{0}$$ β 0 , υ 0 ) at K = 14. Ellipses represent covariance of each cluster. Core descriptions previously reported (Expedition 314 Scientists 2009b) are shown on the right and dotted black lines. The original set of hyper parameters shown in the main text (Fig. 7) is the left panel at the central raw. Figure S7. Depth plot of porosity and clustering results for Site C0020 with different hyper parameters ( $${{\varvec{\beta}}}_{0},{{\varvec{\upsilon}}}_{0}$$ β 0 , υ 0 ) at K = 14. Log units previously reported (Expedition 337 Scientists 2013b) are shown on the right and dotted black lines. The original set of hyper parameters shown in the main text (Fig. 12) is the left panel at the central raw. Figure S8. Depth plot of porosity and clustering results for Site C0020 with different depth intervals. The left panel shows the results at a depth interval of 20 cm and K = 14, which is identical to the figure shown in Fig. 12. The right panel shows the results at a depth interval of 40 cm and K = 18. Log units previously reported (Expedition 337 Scientists 2013b) are shown on the right and dotted black lines.
