CA-XTree: Age Estimation of Grouped Gradient Regression Tree with Local Channel Attention

Figure 13

Results. Similar fluctuation of network training and its corresponding network training iteration results. When group number C is 2, 4, 8, and 32 and tree depth is 6, MAE is 4.612, 4.561, 4.569, and 4.579, respectively. Group C is 2, 4, 8, and 32 and tree depth is 7. (a) atte_card = 2_depth = 6. (b) atte_card = 4_depth = 6. (c) atte_card = 8_depth = 6. (d) atte_card = 32_depth = 6. (e) atte_card = 2_depth = 7. (f) atte_card = 4_depth = 7. (g) atte_card = 8_depth = 7. (h) atte_card = 32_depth = 7.
