Our results show that when trained with the proposed class-balanced loss, the network is able to achieve signifi-cant performance gains on long-tailed datasets. 1.

We believe that a large-scale ontology of images is a critical resource for developing advanced, large-scale content-based image search and image understanding algo-rithms, as well as for providing critical training and bench-marking data for such algorithms. ImageNet uses the hierarchical structure of WordNet [9].

by showing substantially higher image classification accu-racy on the ImageNet Large Scale Visual Recognition Chal-lenge (ILSVRC) [9,10]. Their success resulted from train-ing a large CNN on 1.2 million labeled images, together with a few twists on LeCun’s CNN (e.g., max(x;0) rectify-ing non-linearities and “dropout” regularization).

A Hierarchical Graph Network for 3D Object Detection on ...

3. Hierarchical Graph Network 3.1. Motivation and Overview We aim to develop a new effective method for 3D ob-ject detection on point clouds. Different from 2D image data, point clouds often do not present clear object shape information (e.g., corners and edges), and thus some shape-attentive feature extractors are needed to process point clouds.

Siamese Neural Networks for One-shot Image Recognition

In a series of several papers, the authors modeled the process of drawing characters generatively to decompose the image into small pieces (Lake et al.,2011; 2012). The goal of HBPL is to determine a structural ex-planation for the observed pixels. However, inference un-
