Updates

• (2024.09.20) VideoTGB is accepted at EMNLP 2024! 🔥🔥
• (2024.02.27) Paper Release, check it on Arxiv.

Overview

This is a chat agent based on our work Efficient Temporal Extrapolation of Multimodal Large Language Models with Temporal Grounding Bridge for Long Video Understanding. This work is finetuned on video-instruction datasets and image-instruction datasets.

We have meticulously chosen two distinct architectural paradigms for our study: the encoder-decoder architecture, exemplified by BLIP2-Flan-T5-xl (original version), and the decoder-only architecture, represented by InstructBLIP-Vicuna-7B (original version). For further exploration, we also provide the code to tune the LLM with LoRA.

How to run

Our training framework offers tailored scripts to meet the diverse needs of researchers.

Train model

# run on local
python src/train.py experiment=LSTP_SF_blip2flant5xl_videoinstruct # blip2-flan-t5-xl + video-instruct
python src/train.py experiment=LSTP_SF_instructblipvicuna7b_videoinstruct # instructblip-vicuna-7b + video-instruct

# run on cluster
sbatch scripts/videoinstruct_train.slurm # blip2-flan-t5-xl + video-instruct
sbatch scripts/videoinstruct_vicuna_train.slurm # instructblip-vicuna-7b + video-instruct

For those with limited GPU resources, we also provide the pipeline to shorten the training procedure

# step 1: generate the pseudo labels from the base-model, and extract the optical flow in advance

# step 2: train the temporal sampler
python src/train.py experiment=LSTP_TG_blip2flant5xl_videoinstruct

# step 3: train VideoTGB with fixed temporal sampler
python src/train.py experiment=LSTP_blip2flant5xl_ivinstruct # blip2-flan-t5-xl + video-instruct + image-instruct
python src/train.py experiment=LSTP_instructblipvicuna7b_ivinstruct # instructblip-vicuna-7b + video-instruct + image-instruct
python src/train.py experiment=LSTP_blip2flant5xl_ivtinstruct # blip2-flan-t5-xl (LoRA) + video-instruct + image-instruct + text-instruct
python src/train.py experiment=LSTP_instructblipvicuna7b_ivtinstruct # instructblip-vicuna-7b (LoRA) + video-instruct + image-instruct + text-instruct
