+There are 2 variants of the dataset based on number of variables used -
+2 variables and 3 variables which can be found in the respective zip files.
+Once you extract any of them you will see the following tree -
+
+├── char_only
+│   └── metadata.csv
+│   └── *.png
+├── counting
+│   └── metadata.csv
+│   └── *.png
+├── icon_only
+│   └── metadata.csv
+│   └── *.png
+├── icon_partial
+│   └── metadata.csv
+│   └── *.png
+└── [two/three]-vars.txt
+
+The char_only, icon_only, icon_partial, counting points to the
+symbolic, visual, visual-symbolic and counting datasets mentioned in the paper
+respectively. Each of them consist of the following metadata -
+1. file_path to corresponding image
+2. solution to variable
+3. mapping to symbolic variable (in case of visual, visual-symbolic, counting dataset)
+
+The base equations which are used to create the same are attached in the respective .txt file in the root level directory.
