Extreme Zero-Shot Learning for Extreme Text Classification

1 code implementation NAACL 2022 Yuanhao Xiong, Wei-Cheng Chang, Cho-Jui Hsieh, Hsiang-Fu Yu, Inderjit Dhillon

To learn the semantic embeddings of instances and labels with raw text, we propose to pre-train Transformer-based encoders with self-supervised contrastive losses.

Adversarial Attack across Datasets

no code implementations13 Oct 2021 Yunxiao Qin, Yuanhao Xiong, JinFeng Yi, Lihong Cao, Cho-Jui Hsieh

In this paper, we define a Generalized Transferable Attack (GTA) problem where the attacker doesn't know this information and is acquired to attack any randomly encountered images that may come from unknown datasets.

Learning to Schedule Learning rate with Graph Neural Networks

no code implementations ICLR 2022 Yuanhao Xiong, Li-Cheng Lan, Xiangning Chen, Ruochen Wang, Cho-Jui Hsieh

By constructing a directed graph for the underlying neural network of the target problem, GNS encodes current dynamics with a graph message passing network and trains an agent to control the learning rate accordingly via reinforcement learning.

Training Meta-Surrogate Model for Transferable Adversarial Attack

1 code implementation5 Sep 2021 Yunxiao Qin, Yuanhao Xiong, JinFeng Yi, Cho-Jui Hsieh

In this paper, we tackle this problem from a novel angle -- instead of using the original surrogate models, can we obtain a Meta-Surrogate Model (MSM) such that attacks to this model can be easier transferred to other models?

How much progress have we made in neural network training? A New Evaluation Protocol for Benchmarking Optimizers

no code implementations19 Oct 2020 Yuanhao Xiong, Xuanqing Liu, Li-Cheng Lan, Yang You, Si Si, Cho-Jui Hsieh

For end-to-end efficiency, unlike previous work that assumes random hyperparameter tuning, which over-emphasizes the tuning time, we propose to evaluate with a bandit hyperparameter tuning strategy.

Learning to Learn by Zeroth-Order Oracle

1 code implementation ICLR 2020 Yangjun Ruan, Yuanhao Xiong, Sashank Reddi, Sanjiv Kumar, Cho-Jui Hsieh

In the learning to learn (L2L) framework, we cast the design of optimization algorithms as a machine learning problem and use deep neural networks to learn the update rules.
