MRI-based Multi-task Decoupling Learning for Alzheimer's Disease Detection and MMSE Score Prediction: A Multi-site Validation

1 code implementation2 Apr 2022 Xu Tian, Jin Liu, Hulin Kuang, Yu Sheng, Jianxin Wang, the Alzheimer's Disease Neuroimaging Initiative

First, a multi-task learning network is proposed to implement AD detection and MMSE score prediction, which exploits feature correlation by adding three multi-task interaction layers between the backbones of the two tasks.

Exponential Moving Average Model in Parallel Speech Recognition Training

no code implementations3 Mar 2017 Xu Tian, Jun Zhang, Zejun Ma, Yi He, Juan Wei

As training data rapid growth, large-scale parallel training with multi-GPUs cluster is widely applied in the neural network model learning currently. We present a new approach that applies exponential moving average method in large-scale parallel training of neural network model.
