C-PMI: Conditional Pointwise Mutual Information for Turn-level Dialogue Evaluation

1 code implementation27 Jun 2023 Liliang Ren, Mankeerat Sidhu, Qi Zeng, Revanth Gangi Reddy, Heng Ji, ChengXiang Zhai

Existing reference-free turn-level evaluation metrics for chatbots inadequately capture the interaction between the user and the system.

Sparse Modular Activation for Efficient Sequence Modeling

1 code implementation NeurIPS 2023 Liliang Ren, Yang Liu, Shuohang Wang, Yichong Xu, Chenguang Zhu, ChengXiang Zhai

To validate the effectiveness of SMA on sequence modeling, we design a novel neural architecture, SeqBoat, which employs SMA to sparsely activate a Gated Attention Unit (GAU) based on the state representations learned from an SSM.

HySPA: Hybrid Span Generation for Scalable Text-to-Graph Extraction

1 code implementation Findings (ACL) 2021 Liliang Ren, Chenkai Sun, Heng Ji, Julia Hockenmaier

Text-to-Graph extraction aims to automatically extract information graphs consisting of mentions and types from natural language texts.

A Simple Fix for Convolutional Neural Network via Coordinate Embedding

no code implementations24 Mar 2020 Liliang Ren, Zhuonan Hao

Thus the generalization ability of CNN will be limited since the coordinate information is crucial for a model to learn affine transformations which directly operate on the coordinate of each pixel.

RoNGBa: A Robustly Optimized Natural Gradient Boosting Training Approach with Leaf Number Clipping

no code implementations5 Dec 2019 Liliang Ren, Gen Sun, Jiaman Wu

Natural gradient has been recently introduced to the field of boosting to enable the generic probabilistic predication capability.

Scalable and Accurate Dialogue State Tracking via Hierarchical Sequence Generation

1 code implementation IJCNLP 2019 Liliang Ren, Jianmo Ni, Julian McAuley

Experiments on both the multi-domain and the single domain dialogue state tracking dataset show that our model not only scales easily with the increasing number of pre-defined domains and slots but also reaches the state-of-the-art performance.

Recurrent Soft Attention Model for Common Object Recognition

1 code implementation4 May 2017 Liliang Ren

We propose the Recurrent Soft Attention Model, which integrates the visual attention from the original image to a LSTM memory cell through a down-sample network.
