In this episode, we discuss MG-LLaVA: Towards Multi-Granularity Visual Instruction Tuning by Xiangyu Zhao, Xiangtai Li, Haodong Duan, Haian Huang, Yining Li, Kai Chen, Hua Yang. The study presents MG-LLaVA, a multi-modal large language model designed to process both low-resolution and high-resolution images along with object-centric features for improved perception tasks. It includes a high-resolution visual encoder and a Conv-Gate fusion network to amalgamate fine-grained details with base features, enhancing object recognition using bounding box-derived data from offline detectors. Extensive benchmarking demonstrates MG-LLaVA's superior performance over comparable MLLMs, validated by evaluations using various language encoders ranging from 3.8B to 34B parameters.

In this episode, we discuss 4M-21: An Any-to-Any Vision Model for Tens of Tasks and Modalities by Roman Bachmann, Oğuzhan Fatih Kar, David Mizrahi, Ali Garjani, Mingfei Gao, David Griffiths, Jiaming Hu, Afshin Dehghan, Amir Zamir. The paper presents a novel any-to-any model that significantly extends the capabilities of existing multimodal and multitask foundation models by training on tens of highly diverse modalities, including images, text, geometric data, and more. Through discrete tokenization of various data types and co-training on large-scale datasets, the model can address three times more tasks/modalities than current models without sacrificing performance. The authors demonstrate this with a three billion parameter model, providing open access to the models and training code.

In this episode, we discuss VideoLLM-online: Online Video Large Language Model for Streaming Video by Joya Chen, Zhaoyang Lv, Shiwei Wu, Kevin Qinghong Lin, Chenan Song, Difei Gao, Jia-Wei Liu, Ziteng Gao, Dongxing Mao, Mike Zheng Shou. The paper discusses the development of the Learning-In-Video-Stream (LIVE) framework, which improves large multimodal models' ability to handle real-time streaming video inputs. The framework includes a training objective for continuous input, data generation for streaming dialogue, and an optimized inference pipeline, leading to enhanced performance and speed. This innovation, demonstrated through the VideoLLM-online model built on Llama-2/Llama-3, shows significant improvements in handling streaming videos and achieves state-of-the-art performance in various video-related tasks.
