MIC

Visual Language Models (VLMs) have made significant progress in various downstream tasks by developing large-scale multimodal models. However, they sometimes lack reasoning and contextual learning abilities. On the other hand, Large Language Models (LLMs) have revolutionized the NLP community with their strong reasoning and contextual learning capabilities. LLMs can quickly adapt to new tasks involving inference without fine-tuning pre-trained models or parameter updates, such as question answering and commonsense reasoning.

Studying in context learning abilities contributes to VLMs' ability to generalize new knowledge in lifelong learning environments, develop learnable capabilities, and advance artificial intelligence skills. Therefore, we propose the MIC(Multimodality In-Context Learning) dataset. This is a manually constructed instruction tuning dataset supports interleaved text-image inputs, inter-related multiple image inputs, and multimodal in-context learning inputs. By finetuning VLMs on MIC, we enable them to possess multimodal in-context learning capabilities and understand complex relationships between instructions and multiple images.

Overview

News 🚀

2. [09-15] Our paper has been uploaded to arXiv.
3. [09-01] The MIC data has released on the huggingface hub.
4. [08-23] Reach the 1st on MME, 1st on MMBench
5. [08-21] The MMICL-FLANT5XXL and MMICL-Tiny model has released on the huggingface hub.

MMICL

MMICL(Multi-Modal In-Context Learning) is a multimodal vision-language model that incorporates blip2/instrcutblip. It has the ability to analyze and understand multiple images, as well as follow instructions. MMICL outperforms the VL model of the same size and performs exceptionally well on complex visual reasoning datasets. It achieves state-of-the-art performance on both multimodal task leaderboards and a wide range of vision-language tasks. Furthermore, it showcases new capabilities in video understanding and multimodal in-context learning (M-ICL).

🔥 Further details of model and dataset will be released ASAP.

Reproduce Tips

Since experiments reported in our paper are all conducted on NVIDIA DGX-A40 servers (which might be difficult to acquire), we reimplement MMICL with:

• Ubuntu servers with 4/6* NVIDIA GeForce A40 (46G) GPUs
• Install Apex to enable the bf16 training and evaluation
• Cuda 11.3, deepspeed to enable the zero2-offload and zero3 training
• Packages with certain versions (provided below)

Setup

We conduct our experiment with Anaconda3. If you have installed Anaconda3, then create the environment for MMICL:

conda env create -f environment.yml

MIC Data

Using multiple data source such as: VCR, VQAv2, GQA, COCO, NLVR2, OKVQK, FILCKR, STVQA, MSRVTT, MSRVTTQA, TextVQA, RefCOCO, WikiArt, DiffusionDB, VSR, LLaVa-Instruct, MiniImagenet We tranform it into few shot style and stored it into jsonl files: It forms the all data in to multi instruction style with zero to few-shot form data. runing the preprocessed script and change the data into raw arrow file for further training:
