Simple and Efficient Partial Graph Adversarial Attack: A New Perspective

1 code implementation15 Aug 2023 Guanghui Zhu, Mengyu Chen, Chunfeng Yuan, Yihua Huang

To this end, we propose a totally new method named partial graph attack (PGA), which selects the vulnerable nodes as attack targets.

Enhancing Virtual Assistant Intelligence: Precise Area Targeting for Instance-level User Intents beyond Metadata

no code implementations7 Jun 2023 Mengyu Chen, Zhenchang Xing, Jieshan Chen, Chunyang Chen, Qinghua Lu

Although their capabilities of processing user intents have been developed rapidly, virtual assistants in most platforms are only capable of handling pre-defined high-level tasks supported by extra manual efforts of developers.

Convolutional Neural Network with Pruning Method for Handwritten Digit Recognition

no code implementations15 Jan 2021 Mengyu Chen

The evaluation results show that: for the fully connected layer size, there is a threshold, so that when the layer size increases, the recognition accuracy grows if the layer size smaller than the threshold, and falls if the layer size larger than the threshold; the performance of pruning performed on CNN is worse than on NN; as pruning angle threshold increases, the fully connected layer size and the recognition accuracy decreases.
