As 3D content becomes increasingly prevalent, there's a growing focus on the development of engagements with virtual content. Unfortunately, traditional techniques for creating, editing, and interacting this are fraught difficulties. They tend to be not only engineering-intensive but also require extensive expertise, which adds frustration inefficiency in object manipulation. Our proposed VR-GS system represents leap forward human-centered interaction, offering seamless intuitive user...
Sentence Simplification aims to rephrase complex sentences into simpler while retaining original meaning. Large Language models (LLMs) have demonstrated the ability perform a variety of natural language processing tasks. However, it is not yet known whether LLMs can be served as high-quality sentence simplification system. In this work, we empirically analyze zero-/few-shot learning by evaluating them on number benchmark test sets. Experimental results show outperform state-of-the-art...
