TSMixer: An All-MLP Architecture for Time Series Forecasting

2 code implementations10 Mar 2023 Si-An Chen, Chun-Liang Li, Nate Yoder, Sercan O. Arik, Tomas Pfister

Extending them, in this paper, we investigate the capabilities of linear models for time-series forecasting and present Time-Series Mixer (TSMixer), a novel architecture designed by stacking multi-layer perceptrons (MLPs).

Improving Model Compatibility of Generative Adversarial Networks by Boundary Calibration

no code implementations3 Nov 2021 Si-An Chen, Chun-Liang Li, Hsuan-Tien Lin

To improve GAN in terms of model compatibility, we propose Boundary-Calibration GANs (BCGANs), which leverage the boundary information from a set of pre-trained classifiers using the original data.

A Unified View of cGANs with and without Classifiers

1 code implementation NeurIPS 2021 Si-An Chen, Chun-Liang Li, Hsuan-Tien Lin

Conditional Generative Adversarial Networks (cGANs) are implicit generative models which allow to sample from class-conditional distributions.

Parameter Selection: Why We Should Pay More Attention to It

no code implementations ACL 2021 Jie-Jyun Liu, Tsung-Han Yang, Si-An Chen, Chih-Jen Lin

In the topic of multi-label classification for medical code prediction, one influential paper conducted a proper parameter selection on a set, but when moving to a subset of frequently occurring labels, the authors used the same parameters without a separate tuning.

Active Deep Q-learning with Demonstration

no code implementations6 Dec 2018 Si-An Chen, Voot Tangkaratt, Hsuan-Tien Lin, Masashi Sugiyama

In this work, we propose Active Reinforcement Learning with Demonstration (ARLD), a new framework to streamline RL in terms of demonstration efforts by allowing the RL agent to query for demonstration actively during training.
