This guide provides an in-depth look at implementing TSPM, significantly enhancing your AVQA capabilities. Ready to boost your results?

What is TSPM and Why Should You Use It?

TSPM, or Temporal and Spatial Perception Module, advances the field by intelligently focusing on key semantic cues. It improves the accuracy and efficiency of audio-visual question answering systems. By selectively attending to relevant information, TSPM goes beyond traditional methods, leading to more insightful and context-aware responses. Benefits include:

• Enhanced Accuracy: Target the most important semantic details from both audio and visual inputs.
• Improved Efficiency: Focus on relevant cues to minimize computational overhead, saving valuable resources.
• State-of-the-Art Performance: Replicate cutting-edge research and achieve top-tier results with comprehensive guidance.

Getting Started with TSPM: Step-by-Step Installation

Here's how to set up TSPM to leverage its power for your projects:

1. Prerequisites: Ensure you have the necessary software installed:

   • Python 3.6+
   • PyTorch 1.6.0
   • TensorboardX
   • FFmpeg
   • NumPy

2. Clone the Repository: Use Git to obtain the TSPM code.

   git clone https://github.com/GeWu-Lab/TSPM.git
   

   Copy

3. Download Datasets: Acquire the necessary datasets for training and testing:

   • MUSIC-AVQA: https://gewu-lab.github.io/MUSIC-AVQA/
   • AVQA: http://mn.cs.tsinghua.edu.cn/avqa/

Feature Extraction: Preparing Your Data for TSPM

Feature extraction converts raw data into a format suitable for the TSPM model. Run these scripts in the feat_script/extract_clip_feat directory:

• python [email protected]
• python [email protected]
• python extract_token-level_feat.py
• python [email protected]

These scripts extract visual features from the video frames. They are crucial for the model to understand the visual context of questions.

Training the TSPM Model for Optimal AVQA Performance

Customize these training parameters to suit your specific needs:

python -u main_train.py --Temp_Selection --top_k 10 \
--Spatio_Perception \
--batch_size 64 --epochs 30 --lr 1e-4 \
--num_workers 12 --gpu 0,1 \
--checkpoint TSPM \
--model_save_dir models

Key Parameters Explained:

• --Temp_Selection: Enables the temporal selection module.
• --Spatio_Perception: Enables the spatial perception module.
• --top_k 10: Selects the top 10 temporal segments.
• --batch_size: Set batch size as per available GPU memory.
• --epochs: Set the number of training epochs.
• --lr: The learning rate to fine-tune your learning process.
• --gpu: Selects the GPUs to utilize your resources efficiently.

Audio Visual Question Answering: Testing and Results

After training, evaluate your model with the following command:

python -u main_test.py --Temp_Selection --top_k 10 \
--Spatio_Perception \
--batch_size 1 --gpu 1 \
--checkpoint TSPM \
--model_save_dir models \
--result_dir results

Ensure your batch size remains small for the testing phase. Results will be saved in the specified result_dir. Understanding and analyzing these results lets you know the overall accuracy.
