+# Crossway Ducks
+
+This is the dataset repo for real world experiments presented in [ICRA'24](https://2024.ieee-icra.org/) paper [Crossway Diffusion: Improving Diffusion-based Visuomotor Policy via Self-supervised Learning](https://arxiv.org/abs/2307.01849). 
+
+These datasets are collected in the same format as [robomimic](https://robomimic.github.io/docs/datasets/overview.html). 
+To train on this dataset (and your own datasets), please modify your config file as follows:
+1. Change `dataset_path` to the path of `hdf5` file.
+2. Use the following `shape_meta`.
+
+```
+shape_meta:
+  action:
+    shape:
+    - 4
+  obs:
+    pos:
+      shape:
+      - 4
+      type: low_dim
+    camera0:
+      shape:
+      - 3
+      - 120
+      - 160
+      type: rgb
+    camera1:
+      shape:
+      - 3
+      - 120
+      - 160
+      type: rgb
+```
+
+For the training and evaluation code, please visit our [github repo](https://github.com/LostXine/crossway_diffusion).
