SKAPP

This repo contains a reference implementation of the SKAPP model described in the following paper:

Xovee Xu, Yifan Zhang, Fan Zhou, and Jingkuan Song
Improving Multimodal Social Media Popularity Prediction via Selective Retrieval Knowledge Augmentation
AAAI Conference on Artificial Intelligence, 2025 .

SKAPP is a multimodal learning framework for social UGCs. It equips with a meta retriever, a selective refiner, and a knowledge augmentation prediction network.

Environmental Settings

Our experiments are conducted on Ubuntu 22.04, a single NVIDIA 3090Ti GPU, 128GB RAM, and Intel i7-13700KF.

Create a virtual environment and install GPU-support packages via Anaconda:

# create virtual environment
conda create --name skapp python=3.9

# activate virtual environment
conda activate skapp

# install other dependencies
# make sure cuda and pytorch are installed 
pip3 install pandas huggingface-hub tqdm scikit-learn transformers angle_emb spacy

Dataset Preparation

First, download the datasets:

• ICIP: http://www.visiongarage.altervista.org/popularitydataset/

• SMPD: https://smp-challenge.com/download.html

• Instagram: https://sites.google.com/site/sbkimcv/dataset/instagram-influencer-dataset

Then place the datasets in the corresponding dataset/raw_dataset/ folder.

The storage format of the dataset is as follows:

Usage

Here we take the ICIP dataset as an example to demonstrate the usage.

Preprocess

Run the following commands for preprocessing the datasets. During the preprocessing, you will download the pretrained models (only once).

cd skapp
python src/preprocess/ICIP/1_build_dataset.py
python src/preprocess/ICIP/2_preprocess.py
python src/preprocess/ICIP/3_retrieval.py
python src/preprocess/ICIP/4_disassemble.py

Pre-training

python src/RRCP/train_all_item.py --dataset_id=ICIP
  
python src/RRCP/train_single_item.py --dataset_id=ICIP_dissembled

Here we train the model skapp_all_items and skapp_single_item. The model parameters will be saved in the path /saved_models/.

Evaluation

Step 1: Obtain RRCP

Remember to replace the "YOUR_PATH" to the actual saved model, e.g., trained_model/model_10.pth.

python src/RRCP/RRCP.py --all_model_path "PATH" --dissembled_model_path "PATH" --dataset_path datasets/ICIP

Step 2: Training

python src/train.py --dataset_id=ICIP  --model_id=skapp

Here we train the model SKAPP with the fine-tuning model. The model parameters will be saved in the path /saved_models/.

Step 3: Evaluation

Remember to replace the actual path model_path, e.g. checkpoint_10_epoch.pkl.

python src/test.py --dataset_id=ICIP --model_id=graph --model_path="PATH"
