1. Improving Visual Storytelling with Multimodal Large Language Models

Abstract

Visual storytelling is an emerging field that combines images and narratives to create engaging and contextually rich stories. Despite its potential, generating coherent and emotionally resonant visual stories remains challenging due to the complexity of aligning visual and textual information. This paper presents a novel approach leveraging large language models (LLMs) and large vision-language models (LVLMs) combined with instruction tuning to address these challenges. We introduce a new dataset comprising diverse visual stories, annotated with detailed captions and multimodal elements. Our method employs a combination of supervised and reinforcement learning to fine-tune the model, enhancing its narrative generation capabilities. Quantitative evaluations using GPT-4 and qualitative human assessments demonstrate that our approach significantly outperforms existing models, achieving higher scores in narrative coherence, relevance, emotional depth, and overall quality. The results underscore the effectiveness of instruction tuning and the potential of LLMs/LVLMs in advancing visual storytelling., Comment: 10 pages

41. Adaptive neural preassigned-time tracking control for stochastic nonlinear systems with output constraint and its application.

Author

Xue, Chunting, Zhao, Feng, Chen, Xiangyong, and Qiu, Jianlong

Abstract

This paper considers an adaptive neural preassigned-time tracking control scheme for non-strict feedback stochastic nonlinear systems subjected to output constraint. Depending on the prescribed performance control idea, the output constraint is resolved. Meanwhile, combined with backstepping control scheme, the novel preassigned-time tracking controller is developed, which can not only make the system output satisfy the constraint condition, but also the track error is constrained within a preassigned region in a finite time, where the settling time is arbitrarily set and independent of any parameters. Furthermore, all signals are semi-globally uniformly ultimately bounded in the closed-loop system. Finally, the validity of the proposed control scheme is demonstrated via the practical one-link manipulator. [ABSTRACT FROM AUTHOR]
