Taxonomy-Structured Domain Adaptation

2 code implementations13 Jun 2023 Tianyi Liu, Zihao Xu, Hao He, Guang-Yuan Hao, Guang-He Lee, Hao Wang

Domain adaptation aims to mitigate distribution shifts among different domains.

Graph-Relational Domain Adaptation

1 code implementation ICLR 2022 Zihao Xu, Hao He, Guang-He Lee, Yuyang Wang, Hao Wang

In this work, we relax such uniform alignment by using a domain graph to encode domain adjacency, e. g., a graph of states in the US with each state as a domain and each edge indicating adjacency, thereby allowing domains to align flexibly based on the graph structure.

Self-Supervised Learning of Appliance Usage

no code implementations ICLR 2020 Chen-Yu Hsu, Abbas Zeitoun, Guang-He Lee, Dina Katabi, Tommi Jaakkola

We show that this cross-modal prediction task allows us to detect when a particular appliance is used, and the location of the appliance in the home, all in a self-supervised manner, without any labeled data.

Locally Constant Networks

1 code implementation ICLR 2020 Guang-He Lee, Tommi S. Jaakkola

We show how neural models can be used to realize piece-wise constant functions such as decision trees.

Oblique Decision Trees from Derivatives of ReLU Networks

1 code implementation30 Sep 2019 Guang-He Lee, Tommi S. Jaakkola

We show how neural models can be used to realize piece-wise constant functions such as decision trees.

$\ell_1$ Adversarial Robustness Certificates: a Randomized Smoothing Approach

no code implementations25 Sep 2019 Jiaye Teng, Guang-He Lee, Yang Yuan

Robustness is an important property to guarantee the security of machine learning models.

Towards Robust, Locally Linear Deep Networks

no code implementations ICLR 2019 Guang-He Lee, David Alvarez-Melis, Tommi S. Jaakkola

In this paper, we propose a new learning problem to encourage deep networks to have stable derivatives over larger regions.

Tight Certificates of Adversarial Robustness for Randomly Smoothed Classifiers

1 code implementation NeurIPS 2019 Guang-He Lee, Yang Yuan, Shiyu Chang, Tommi S. Jaakkola

Specifically, an $\ell_2$ bounded adversary cannot alter the ensemble prediction generated by an additive isotropic Gaussian noise, where the radius for the adversary depends on both the variance of the distribution as well as the ensemble margin at the point of interest.

ProbGAN: Towards Probabilistic GAN with Theoretical Guarantees

1 code implementation ICLR 2019 Hao He, Hao Wang, Guang-He Lee, Yonglong Tian

Probabilistic modelling is a principled framework to perform model aggregation, which has been a primary mechanism to combat mode collapse in the context of Generative Adversarial Networks (GAN).

Game-Theoretic Interpretability for Temporal Modeling

no code implementations30 Jun 2018 Guang-He Lee, David Alvarez-Melis, Tommi S. Jaakkola

In contrast, we focus on temporal modeling and the problem of tailoring the predictor, functionally, towards an interpretable family.

MUSE: Modularizing Unsupervised Sense Embeddings

1 code implementation EMNLP 2017 Guang-He Lee, Yun-Nung Chen

This paper proposes to address the word sense ambiguity issue in an unsupervised manner, where word sense representations are learned along a word sense selection mechanism given contexts.

Toward Implicit Sample Noise Modeling: Deviation-driven Matrix Factorization

no code implementations28 Oct 2016 Guang-He Lee, Shao-Wen Yang, Shou-De Lin

Specifically, by modeling and learning the deviation of data, we design a novel matrix factorization model.
