-\begin{table}[h]
-\caption{Overall comparison of error rates ($\pm$ std.err.) on 62 character classes (10 digits +
-26 lower + 26 upper), except for last columns -- digits only, between deep architecture with pre-training
-(SDA=Stacked Denoising Autoencoder) and ordinary shallow architecture 
-(MLP=Multi-Layer Perceptron). The models shown are all trained using perturbed data (NISTP or P07)
-and using a validation set to select hyper-parameters and other training choices. 
-\{SDA,MLP\}0 are trained on NIST,
-\{SDA,MLP\}1 are trained on NISTP, and \{SDA,MLP\}2 are trained on P07.
-The human error rate on digits is a lower bound because it does not count digits that were
-recognized as letters. For comparison, the results found in the literature
-on NIST digits classification using the same test set are included.}

-\caption{Relative change in error rates due to the use of perturbed training data,
-either using NISTP, for the MLP1/SDA1 models, or using P07, for the MLP2/SDA2 models.
-A positive value indicates that training on the perturbed data helped for the
-given test set (the first 3 columns on the 62-class tasks and the last one is
-on the clean 10-class digits). Clearly, the deep learning models did benefit more
-from perturbed training data, even when testing on clean data, whereas the MLP
-trained on perturbed data performed worse on the clean digits and about the same
-on the clean characters. }

-\caption{Test error rates and relative change in error rates due to the use of
-a multi-task setting, i.e., training on each task in isolation vs training
-for all three tasks together, for MLPs vs SDAs. The SDA benefits much
-more from the multi-task setting. All experiments on only on the
-unperturbed NIST data, using validation error for model selection.
-Relative improvement is 1 - single-task error / multi-task error.}
