Query: Interactive Model with Structural Loss for Language-based Abductive
  Reasoning   The abductive natural language inference task ($\alpha$NLI) is proposed to
infer the most plausible explanation between the cause and the event. In the
$\alpha$NLI task, two observations are given, and the most plausible hypothesis
is asked to pick out from the candidates. Existing methods model the relation
between each candidate hypothesis separately and penalize the inference network
uniformly. In this paper, we argue that it is unnecessary to distinguish the
reasoning abilities among correct hypotheses; and similarly, all wrong
hypotheses contribute the same when explaining the reasons of the observations.
Therefore, we propose to group instead of ranking the hypotheses and design a
structural loss called ``joint softmax focal loss'' in this paper. Based on the
observation that the hypotheses are generally semantically related, we have
designed a novel interactive language model aiming at exploiting the rich
interaction among competing hypotheses. We name this new model for $\alpha$NLI:
Interactive Model with Structural Loss (IMSL). The experimental results show
that our IMSL has achieved the highest performance on the RoBERTa-large
pretrained model, with ACC and AUC results increased by about 1\% and 5\%
respectively.
