 This is the dataset repository for SCAN MCD splits. In total, there are three splits - mcd1, mcd2, and mcd3
 
+SCAN is a set of simple language-driven navigation tasks for studying compositional learning and zero-shot generalization. The SCAN tasks were inspired by the CommAI environment, which is the origin of the acronym (Simplified versions of the CommAI Navigation tasks).
+
+The relevant SCAN paper is: 
+
+[Generalization without systematicity: On the compositional skills of sequence-to-sequence recurrent networks](https://arxiv.org/pdf/1711.00350). ICML 2018.
+
+The relevant MCD split paper is: 
+
+[Measuring Compositional Generalization: A Comprehensive Method on Realistic Data](https://arxiv.org/pdf/1912.09713). ICLR 2020.
+

 You can load them by:
 ```datasets.load_dataset("Punchwe/SCAN_MCDSplits", name="mcd1", split="train")```
