This paper formulates a forest representation learning approach (CASDF) as an additive model which boosts the augmented features and improves the upper bound on the generalization gap (by removing square root). The analysis results in a margin distribution reweighting scheme for deep forests. The paper is well-written, and is well-organized. Also the majority of reviewers find the contributions in the paper significant. However, R3 finds the experiments in the paper very limited. Nevertheless, given that the main emphasis and contribution of the paper is in theoretical analysis, I am fine with limited experimentation. Considering overall rating of this work, I recommend accept.
