Self-Supervised Robust Scene Flow Estimation via the Alignment of Probability Density Functions

no code implementations23 Mar 2022 Pan He, Patrick Emami, Sanjay Ranka, Anand Rangarajan

Scene flow estimation is therefore converted into the problem of recovering motion from the alignment of probability density functions, which we achieve using a closed-form expression of the classic Cauchy-Schwarz divergence.

Protum: A New Method For Prompt Tuning Based on "[MASK]"

no code implementations28 Jan 2022 Pan He, Yuxi Chen, Yan Wang, Yanru Zhang

In response to the above issue, we propose a new \textbf{Pro}mpt \textbf{Tu}ning based on "[\textbf{M}ASK]" (\textbf{Protum}) method in this paper, which constructs a classification task through the information carried by the hidden layer of "[MASK]" tokens and then predicts the labels directly rather than the answer tokens.

Adaptive Adversarial Attack on Scene Text Recognition

no code implementations9 Jul 2018 Xiaoyong Yuan, Pan He, Xiaolin Andy Li, Dapeng Oliver Wu

We observe two critical obstacles in adversarial examples: (i) Strong adversarial attacks (e. g., C&W attack) require manually tuning hyper-parameters and take a long time to construct an adversarial example, making it impractical to attack real-time systems; (ii) Most of the studies focus on non-sequential tasks, such as image classification, yet only a few consider sequential tasks.
