Cooperative Coevolutionary CMA-ES With Landscape-Aware Grouping in Noisy Environments

2022 · IEEE Transactions on Evolutionary Computation

Many real-world optimization tasks suffer from noise. So far, the research on noise-tolerant optimization algorithms is still restricted to low-dimensional problems with less than 100 decision variables. In reality, many problems are high dimensional. Cooperative …

Surrogate-assisted evolutionary neural architecture search with network embedding

2022 · Complex & Intelligent Systems

Abstract To accelerate the performance estimation in neural architecture search, recently proposed algorithms adopt surrogate models to predict the performance of neural architectures instead of training the network from scratch. However, it is time-consuming to …

Implicit Jailbreak Attacks via Cross-Modal Information Concealment on Vision-Language Models

2025 · arXiv (Cornell University)

Multimodal large language models (MLLMs) enable powerful cross-modal reasoning capabilities. However, the expanded input space introduces new attack surfaces. Previous jailbreak attacks often inject malicious instructions from text into less aligned modalities, such as vision. …
