 ## Dataset Summary
+The data was obtained from the updated Google Drive link shared by the authors on Feb 15, 2023, 
+see the [commit](https://github.com/UCSD-AI4H/PathVQA/commit/117e7f4ef88a0e65b0e7f37b98a73d6237a3ceab)
+in the GitHub repository. This version of the dataset contains a total of 5,004 images and 32,795 question-answer pairs. 
+Out of the 5,004 images, 4,289 images are referenced by a question-answer pair, while 715 images are not used.
+Furthermore, there are several duplicates, i.e. there are some image-question-answer triplets which occur

+triplets, the dataset contains 32,632 question-answer pairs on 4,289 images.
