Question: Which baselines did they compare against?

Evidence:
raw_evidence: FLOAT SELECTED: Table 1: The comparison of various models on different sentence classification tasks. We report the test accuracy of each model in percentage. Our SATA Tree-LSTM shows superior or competitive performance on all tasks, compared to previous treestructured models as well as other sophisticated models. ?: Latent tree-structured models. †: Models which are pre-trained with large external corpora.
Our experimental results on the SNLI dataset are shown in table 2 . In this table, we report the test accuracy and number of trainable parameters for each model. Our SATA-LSTM again demonstrates its decent performance compared against the neural models built on both syntactic trees and latent trees, as well as the non-tree models. (Latent Syntax Tree-LSTM: BIBREF10 ( BIBREF10 ), Tree-based CNN: BIBREF35 ( BIBREF35 ), Gumbel Tree-LSTM: BIBREF11 ( BIBREF11 ), NSE: BIBREF36 ( BIBREF36 ), Reinforced Self-Attention Network: BIBREF4 ( BIBREF4 ), Residual stacked encoders: BIBREF37 ( BIBREF37 ), BiLSTM with generalized pooling: BIBREF38 ( BIBREF38 ).) Note that the number of learned parameters in our model is also comparable to other sophisticated models, showing the efficiency of our model.
