For a fixed N, the Rademacher complexity of GF,N can be bounded as follows for any m 1: Rm(GF,N)  1 n Pp k=1 Nk Rm(Hk). Thus, the following standard margin-based Rademacher complexity bound holds (Koltchinskii & Panchenko, 2002). For any > 0, with probability at least 1 , for all g 2 GF,N, R⇢(g) b RS,⇢(g)  2 ⇢ 1

Calibrated Boosting-Forest

Excellent ranking power along with well calibrated probability estimates are needed in many classification tasks. In this paper, we introduce a technique, Calibrated Boosting-Forest1 that captures both. This novel technique is an ensemble of gradient boosting machines that can support both continuous and binary labels. While offering superior ranking power over any individual regression or clas...

Deep Incremental Boosting

This paper introduces Deep Incremental Boosting, a new technique derived from AdaBoost, specifically adapted to work with Deep Learning methods, that reduces the required training time and improves generalisation. We draw inspiration from Transfer of Learning approaches to reduce the start-up time to training each incremental Ensemble member. We show a set of experiments that outlines some prel...

Boosted Residual Networks

In this paper we present a new ensemble method, called Boosted Residual Networks, which builds an ensemble of Residual Networks by growing the member network at each round of boosting. The proposed approach combines recent developements in Residual Networks a method for creating very deep networks by including a shortcut layer between different groups of layers with the Deep Incremental Boostin...

SelfieBoost: A Boosting Algorithm for Deep Learning

We describe and analyze a new boosting algorithm for deep learning called SelfieBoost. Unlike other boosting algorithms, like AdaBoost, which construct ensembles of classifiers, SelfieBoost boosts the accuracy of a single network. We prove a log(1/ ) convergence rate for SelfieBoost under some “SGD success” assumption which seems to hold in practice.

Boosting-like Deep Learning For Pedestrian Detection

This paper proposes boosting-like deep learning (BDL) framework for pedestrian detection. Due to overtraining on the limited training samples, overfitting is a major problem of deep learning. We incorporate a boosting-like technique into deep learning to weigh the training samples, and thus prevent overtraining in the iterative process. We theoretically give the details of derivation of our alg...

KIM et al.: GROWING A TREE FROM DECISION REGIONS OF A BOOSTING CLASSIFIER 1 Making a Shallow Network Deep: Growing a Tree from Decision Regions of a Boosting Classifier

This paper presents a novel way to speed up the classification time of a boosting classifier. We make the shallow (flat) network deep (hierarchical) by growing a tree from the decision regions of a given boosting classifier. This provides many short paths for speeding up and preserves the reasonably smooth decision regions of the boosting classifier for good generalisation. We express the conve...
