Task: Question Answering
Input (English): In this subsection, we see the influence of each component of a model on performance by removing or replacing its components. the SNLI dataset is used for experiments, and the best performing configuration is used as a baseline for modifications. We consider the following variants: (i) models that use plain stacked LSTMs, (ii) models with different INLINEFORM0 , (iii) models without INLINEFORM1 , and (iv) models that integrate lower contexts via peephole connections. 
 Question: What were the baselines?
Output (English): (i) models that use plain stacked LSTMs (ii) models with different INLINEFORM0 (iii) models without INLINEFORM1 (iv) models that integrate lower contexts via peephole connections
