Our research in RIS focuses on revolutionizing wireless communication by leveraging advanced optimization techniques and deep neural networks. We aim to mitigate signal disruptions in dynamic environments by developing efficient blockage prediction models, ensuring seamless connectivity and improved data transmission. By integrating RIS with cutting-edge AI-driven approaches, our work significantly enhances network efficiency, reduces latency, and optimizes resource allocation, paving the way for next-generation 6G and beyond communication systems.
