Wav2SQL: Direct Generalizable Speech-To-SQL Parsing

no code implementations21 May 2023 Huadai Liu, Rongjie Huang, Jinzheng He, Gang Sun, Ran Shen, Xize Cheng, Zhou Zhao

Speech-to-SQL (S2SQL) aims to convert spoken questions into SQL queries given relational databases, which has been traditionally implemented in a cascaded manner while facing the following challenges: 1) model training is faced with the major issue of data scarcity, where limited parallel data is available; and 2) the systems should be robust enough to handle diverse out-of-domain speech samples that differ from the source data.

PerFED-GAN: Personalized Federated Learning via Generative Adversarial Networks

no code implementations18 Feb 2022 Xingjian Cao, Gang Sun, Hongfang Yu, Mohsen Guizani

Due to the differences of clients, a single global model may not perform well on all clients, so the personalized federated learning method, which trains a personalized model for each client that better suits its individual needs, becomes a research hotspot.

Gather-Excite: Exploiting Feature Context in Convolutional Neural Networks

9 code implementations NeurIPS 2018 Jie Hu, Li Shen, Samuel Albanie, Gang Sun, Andrea Vedaldi

We also propose a parametric gather-excite operator pair which yields further performance gains, relate it to the recently-introduced Squeeze-and-Excitation Networks, and analyse the effects of these changes to the CNN feature activation statistics.

Squeeze-and-Excitation Networks

82 code implementations CVPR 2018 Jie Hu, Li Shen, Samuel Albanie, Gang Sun, Enhua Wu

Squeeze-and-Excitation Networks formed the foundation of our ILSVRC 2017 classification submission which won first place and reduced the top-5 error to 2. 251%, surpassing the winning entry of 2016 by a relative improvement of ~25%.

Multi-level Discriminative Dictionary Learning towards Hierarchical Visual Categorization

no code implementations CVPR 2013 Li Shen, Shuhui Wang, Gang Sun, Shuqiang Jiang, Qingming Huang

For each internode of the hierarchical category structure, a discriminative dictionary and a set of classification models are learnt for visual categorization, and the dictionaries in different layers are learnt to exploit the discriminative visual properties of different granularity.
