Targeted Physical-World Attention Attack on Deep Learning Models in Road Sign Recognition

2020 · arXiv (Cornell University)

Real world traffic sign recognition is an important step towards building autonomous vehicles, most of which highly dependent on Deep Neural Networks (DNNs). Recent studies demonstrated that DNNs are surprisingly susceptible to adversarial examples. Many …

A long-duration Speech Semantic Recognition and Summarization Model for multi-speaker Conversations

2024

This paper aims to propose a comprehensive solution to address challenges in the field of audio processing for long-duration, multi-speaker conversational meetings. The identified issues include multi-speaker voice separation, difficulties in handling long temporal sequences, …

Analogical Reasoning Enhanced Multimodal Knowledge Graph Embedding

2025

Multimodal knowledge graph embedding(MKGE) maps entities and relations from multiple modalities to a continuous vector space to identify potential missing triples in multimodal knowledge graphs. Most existing studies on multimodal knowledge graph embedding belong to …
