MLP Can Be A Good Transformer Learner

1 code implementation8 Apr 2024 Sihao Lin, Pumeng Lyu, Dongrui Liu, Tao Tang, Xiaodan Liang, Andy Song, Xiaojun Chang

We identify that regarding the attention layer in bottom blocks, their subsequent MLP layers, i. e. two feed-forward layers, can elicit the same entropy quantity.

Self-Supervised Multi-Frame Neural Scene Flow

no code implementations24 Mar 2024 Dongrui Liu, Daqi Liu, Xueqian Li, Sihao Lin, Hongwei Xie, Bing Wang, Xiaojun Chang, Lei Chu

Neural Scene Flow Prior (NSFP) and Fast Neural Scene Flow (FNSF) have shown remarkable adaptability in the context of large out-of-distribution autonomous driving.

Concept-Level Explanation for the Generalization of a DNN

no code implementations25 Feb 2023 Huilin Zhou, Hao Zhang, Huiqi Deng, Dongrui Liu, Wen Shen, Shih-Han Chan, Quanshi Zhang

Therefore, in this paper, we investigate the generalization power of each interactive concept, and we use the generalization power of different interactive concepts to explain the generalization power of the entire DNN.

Self-Supervised Point Cloud Registration with Deep Versatile Descriptors

no code implementations25 Jan 2022 Dongrui Liu, Chuanchuan Chen, Changqing Xu, Robert Qiu, Lei Chu

In this paper, we propose to jointly use both global and local descriptors to register point clouds in a self-supervised manner, which is motivated by a critical observation that all local geometries of point clouds are transformed consistently under the same transformation.

Trap of Feature Diversity in the Learning of MLPs

no code implementations2 Dec 2021 Dongrui Liu, Shaobo Wang, Jie Ren, Kangrui Wang, Sheng Yin, Huiqi Deng, Quanshi Zhang

In this paper, we focus on a typical two-phase phenomenon in the learning of multi-layer perceptrons (MLPs), and we aim to explain the reason for the decrease of feature diversity in the first phase.

Interpreting Representation Quality of DNNs for 3D Point Cloud Processing

no code implementations NeurIPS 2021 Wen Shen, Qihan Ren, Dongrui Liu, Quanshi Zhang

In this paper, we evaluate the quality of knowledge representations encoded in deep neural networks (DNNs) for 3D point cloud processing.
