# Cortical Policy: A Dual-Stream View Transformer for Robotic Manipulation
|
| 11 |
+
|

+
[](https://arxiv.org/pdf/2603.21051)
|
| 13 |
+
[](https://github.com/iLearn-Lab/ICLR26-Cortical_Policy)
|
| 14 |
+
|
| 15 |
+
**Official pretrained weights for Cortical Policy (ICLR 2026).** This model integrates static and dynamic visual streams to enhance spatial reasoning and dynamic adaptation for robotic manipulation.

+
## 📂 Repository Structure
|
| 19 |
+
|
| 20 |
+
This repository contains the necessary checkpoints to run and evaluate the Cortical Policy framework. The weights are organized into two main categories:
|
| 21 |
+
|
| 22 |
+
* **`dynamic_view_stream_backbone_weights/`**: Contains the pretrained weights for the Gaze Model (dynamic-view stream), pre-trained on Ego4D and fine-tuned for position awareness.
|
| 23 |
+
* **`policy_weights/`**: Contains the final trained policy checkpoints (`model.pth`) along with the corresponding YAML configuration files (`exp_cfg.yaml`, `mvt_cfg.yaml`).
