REPS: Reconstruction-based Point Cloud Sampling

1 code implementation8 Mar 2024 Guoqing Zhang, Wenbo Zhao, Jian Liu, Xianming Liu

Our method outperforms previous approaches in preserving the structural features of the sampled point clouds.

Mitigating Bias for Question Answering Models by Tracking Bias Influence

no code implementations13 Oct 2023 Mingyu Derek Ma, Jiun-Yu Kao, Arpit Gupta, Yu-Hsiang Lin, Wenbo Zhao, Tagyoung Chung, Wei Wang, Kai-Wei Chang, Nanyun Peng

Based on the intuition that a model would lean to be more biased if it learns from a biased example, we measure the bias level of a query instance by observing its influence on another instance.

On Compositionality and Improved Training of NADO

no code implementations20 Jun 2023 Sidi Lu, Wenbo Zhao, Chenyang Tao, Arpit Gupta, Shanchan Wu, Tagyoung Chung, Nanyun Peng

NeurAlly-Decomposed Oracle (NADO) is a powerful approach for controllable generation with large language models.

Exploring Energy-based Language Models with Different Architectures and Training Methods for Speech Recognition

1 code implementation22 May 2023 Hong Liu, Zhaobiao Lv, Zhijian Ou, Wenbo Zhao, Qing Xiao

Energy-based language models (ELMs) parameterize an unnormalized distribution for natural sentences and are radically different from popular autoregressive language models (ALMs).

Unsupervised Melody-Guided Lyrics Generation

no code implementations12 May 2023 Yufei Tian, Anjali Narayan-Chen, Shereen Oraby, Alessandra Cervone, Gunnar Sigurdsson, Chenyang Tao, Wenbo Zhao, Tagyoung Chung, Jing Huang, Nanyun Peng

At inference time, we leverage the crucial alignments between melody and lyrics and compile the given melody into constraints to guide the generation process.

Self-Supervised Arbitrary-Scale Point Clouds Upsampling via Implicit Neural Representation

1 code implementation CVPR 2022 Wenbo Zhao, Xianming Liu, Zhiwei Zhong, Junjun Jiang, Wei Gao, Ge Li, Xiangyang Ji

Most existing methods either take the end-to-end supervised learning based manner, where large amounts of pairs of sparse input and dense ground-truth are exploited as supervision information; or treat up-scaling of different scale factors as independent tasks, and have to build multiple networks to handle upsampling with varying factors.

Simple Question Answering with Subgraph Ranking and Joint-Scoring

no code implementations NAACL 2019 Wenbo Zhao, Tagyoung Chung, Anuj Goyal, Angeliki Metallinou

Using this framework as a starting point, we focus on two aspects: improving subgraph selection through a novel ranking method and leveraging the subject--relation dependency by proposing a joint scoring CNN model with a novel loss function that enforces the well-order of scores.

Hierarchical Routing Mixture of Experts

no code implementations18 Mar 2019 Wenbo Zhao, Yang Gao, Shahan Ali Memon, Bhiksha Raj, Rita Singh

Addressing these problems, we propose a binary tree-structured hierarchical routing mixture of experts (HRME) model that has classifiers as non-leaf node experts and simple regression models as leaf node experts.
