  author={Eric-Tuan Le and Iasonas Kokkinos and Niloy Jyoti Mitra},
In this work, we introduce three generic point cloud processing blocks that improve both accuracy and memory consumption of state-of-the-art networks thus allowing to design deeper and more accurate networks. [...] Key Result We report a 3.4% increase in IoU on the -most complex- PartNet dataset while decreasing memory footprint by 57%.Expand

Aggregated Residual Transformations for Deep Neural Networks
On the ImageNet-1K dataset, it is empirically show that even under the restricted condition of maintaining complexity, increasing cardinality is able to improve classification accuracy and is more effective than going deeper or wider when the authors increase the capacity. Expand
Training Deep Nets with Sublinear Memory Cost
This work designs an algorithm that costs O( √ n) memory to train a n layer network, with only the computational cost of an extra forward pass per mini-batch, and shows that it is possible to trade computation for memory giving a more memory efficient training algorithm with a little extra computation cost.

Multiresolution Tree Networks for 3D Point Cloud Processing
This model represents a 3D shape as a set of locality-preserving 1D ordered list of points at multiple resolutions, which allows efficient feed-forward processing through 1D convolutions, coarse-to-fine analysis through a multi-grid architecture, and it leads to faster convergence and small memory footprint during training.
