Split-and-Fit: Learning B-Reps via Structure-Aware Voronoi Partitioning

1 code implementation7 Jun 2024 Yilin Liu, Jiale Chen, Shanshan Pan, Daniel Cohen-Or, Hao Zhang, Hui Huang

We design a neural network to predict the Voronoi diagram from an input point cloud or distance field via a binary classification.

VM-Rec: A Variational Mapping Approach for Cold-start User Recommendation

no code implementations2 Nov 2023 Linan Zheng, Jiale Chen, Pengsheng Liu, Guangfa Zhang, Jinyun Fang

We observe that the model can generate expressive embeddings for warm users with relatively more interactions.

In a randomized exam, each student is asked a small number of random questions from a large question bank.


Equal Affection or Random Selection: the Quality of Subjective Feedback from a Group Perspective

no code implementations24 Feb 2021 Jiale Chen, Yuqing Kong, Yuxuan Lu

With this assumption, we propose a new definition for uninformative feedback and correspondingly design a family of evaluation metrics, called f-variety, for group-level feedback which can 1) distinguish informative feedback and uninformative feedback (separation) even if their statistics are both uniform and 2) decrease as the ratio of uninformative respondents increases (monotonicity).

A Study of Multilingual Neural Machine Translation

no code implementations25 Dec 2019 Xu Tan, Yichong Leng, Jiale Chen, Yi Ren, Tao Qin, Tie-Yan Liu

Multilingual neural machine translation (NMT) has recently been investigated from different aspects (e. g., pivot translation, zero-shot translation, fine-tuning, or training from scratch) and in different settings (e. g., rich resource and low resource, one-to-many, and many-to-one translation).

Multilingual Neural Machine Translation with Language Clustering

no code implementations IJCNLP 2019 Xu Tan, Jiale Chen, Di He, Yingce Xia, Tao Qin, Tie-Yan Liu

We study two methods for language clustering: (1) using prior knowledge, where we cluster languages according to language family, and (2) using language embedding, in which we represent each language by an embedding vector and cluster them in the embedding space.

Language Graph Distillation for Low-Resource Machine Translation

no code implementations17 Aug 2019 Tianyu He, Jiale Chen, Xu Tan, Tao Qin

Neural machine translation on low-resource language is challenging due to the lack of bilingual sentence pairs.

Asynchronous Episodic Deep Deterministic Policy Gradient: Towards Continuous Control in Computationally Complex Environments

1 code implementation3 Mar 2019 Zhizheng Zhang, Jiale Chen, Zhibo Chen, Weiping Li

Not limited to the control tasks in computationally complex environments, AE-DDPG also achieves higher rewards and 2- to 4-fold improvement in sample efficiency on average compared to other variants of DDPG in MuJoCo environments.
