MG LLaVA
Overview :
MG-LLaVA is a machine learning language model (MLLM) designed to enhance the visual processing capabilities of models. It achieves this by incorporating a multi-granularity visual pipeline, encompassing low-resolution, high-resolution, and object-centric features. An additional high-resolution visual encoder is introduced to capture finer details, and a Conv-Gate fusion network is used to integrate these high-resolution features with the base visual features. Furthermore, object-level features derived from offline detector bounding boxes are integrated to further refine the model's object recognition abilities. Trained via instruction tuning on publicly available multimodal data, MG-LLaVA exhibits exceptional perceptual skills.
Target Users :
MG-LLaVA is primarily designed for machine learning researchers and developers, particularly those specializing in visual language models and multimodal learning. It is suitable for users who work with large volumes of visual and textual data and aim to enhance their models' performance in image recognition and text understanding.
