Visual Instruction Tuning towards General-Purpose Multimodal Model: A Survey

no code implementations27 Dec 2023 Jiaxing Huang, Jingyi Zhang, Kai Jiang, Han Qiu, Shijian Lu

Traditional computer vision generally solves each single task independently by a dedicated model with the task instruction implicitly designed in the model architecture, arising two limitations: (1) it leads to task-specific models, which require multiple models for different tasks and restrict the potential synergies from diverse tasks; (2) it leads to a pre-defined and fixed model interface that has limited interactivity and adaptability in following user' task instructions.
