## 🧩 Introduction
This is the code base for our paper on [Learning Fused State Representations for Control from Multi-View Observations]. we propose **M**ulti-view **F**usion **S**tate for **C**ontrol (**MFSC**), firstly incorporating bisimulation metrics learning into MVRL to learn task-relevant representations. Furthermore, we propose a multiview-based mask and latent reconstruction auxiliary task that exploits shared information across views and improves MFSC’s robustness in missing views by introducing a mask token.

## ⚒️ Installation
For installation and setup instructions for each environment, please refer to the corresponding subdirectories under envs/ or their README files. You may also refer to the setup guidelines from [Keypoint3D](https://github.com/buoyancy99/unsup-3d-keypoints) and [DBC](https://github.com/facebookresearch/deep_bisim4control) for additional reference and compatibility.

## 📖 Run Experiments
We evaluate our method on a set of 3D manipulation environments **Meta-World**, a high degree of freedom 3D locomotion environment **PyBullet's Ant**, and a more realistic multi-view highway driving scenario, **CARLA**. 

To train MFSC from scratch on each benchmark, simply execute the corresponding .sh script located in its respective directory:
```
# Meta-world
$ bash run.sh

# Pybullet's Ant
$ bash run.sh

# CARLA
bash run_local_carla096.sh
```

## 🚀 Checkpoints and Original Data
We have made all original training log data, along with intermediate model checkpoints, available in our [Hugging Face repository](https://huggingface.co/datasets/Arya87/MFSC_ICML_2025). We hope this resource is helpful for your experiments and further research.
