CO2: Efficient Distributed Training with Full Communication-Computation Overlap

1 code implementation29 Jan 2024 Weigao Sun, Zhen Qin, Weixuan Sun, Shidi Li, Dong Li, Xuyang Shen, Yu Qiao, Yiran Zhong

CO2 is able to attain a high scalability even on extensive multi-node clusters constrained by very limited communication bandwidth.

Sampled Transformer for Point Sets

no code implementations28 Feb 2023 Shidi Li, Christian Walder, Alexander Soen, Lexing Xie, Miaomiao Liu

The sparse transformer can reduce the computational complexity of the self-attention layers to $O(n)$, whilst still being a universal approximator of continuous sequence-to-sequence functions.

SPA-VAE: Similar-Parts-Assignment for Unsupervised 3D Point Cloud Generation

no code implementations15 Mar 2022 Shidi Li, Christian Walder, Miaomiao Liu

This paper addresses the problem of unsupervised parts-aware point cloud generation with learned parts-based self-similarity.

EditVAE: Unsupervised Part-Aware Controllable 3D Point Cloud Shape Generation

no code implementations13 Oct 2021 Shidi Li, Miaomiao Liu, Christian Walder

We achieve this with a simple modification of the Variational Auto-Encoder which yields a joint model of the point cloud itself along with a schematic representation of it as a combination of shape primitives.

Interval-censored Hawkes processes

no code implementations16 Apr 2021 Marian-Andrei Rizoiu, Alexander Soen, Shidi Li, Pio Calderon, Leanne Dong, Aditya Krishna Menon, Lexing Xie

We propose the multi-impulse exogenous function - for when the exogenous events are observed as event time - and the latent homogeneous Poisson process exogenous function - for when the exogenous events are presented as interval-censored volumes.
