Copied from Reddit FYI.<p>As the second author of the paper, I have to say &quot;Wrong Guess&quot;, :), we didn&#x27;t try the other 18. The story is as follows. We had this idea in early March as a reasoning component of our bigger (and cool) neural system. In early May my student intern (the first author) decided to implement it, but he said &quot;why don&#x27;t we try this on a couple of hard bAbi tasks on which Memory Net failed？&quot;, and then we are here. That said, I don&#x27;t mean Neural Reasoner can easily solve them without any model tweaking, considering some of them are formulated slightly differently from the two we tried . But more importantly, it was never our goal to nail an artificial data set.
