Reproducibility Variable Result LLM Response
Research Type Experimental Our experiments show that even without default augmentations, we can learn an augmentation policy that achieves strong performance with that of previous works. Extensive ablation studies show that the regularized gradient matching is an effective search method for data augmentation policies. Our code is available at: https://github.com/MSU-MLSys-Lab/Deep AA.

Pseudocode No The paper includes mathematical equations for its formulation but does not provide any structured pseudocode or algorithm blocks.
Open Source Code Yes Our code is available at: https://github.com/MSU-MLSys-Lab/Deep AA.
Open Datasets Yes We evaluate the performance of Deep AA on three datasets CIFAR-10, CIFAR-100, and Image Net and compare it with existing automated data augmentation search methods
Dataset Splits No The paper mentions training on 'a subset of 4,000 randomly selected samples from CIFAR-10' for policy search and constructing 'a validation batch by sampling a batch of original data from the validation set'. However, it does not explicitly state the specific train/validation/test dataset split percentages or sample counts for the overall experiments.
Hardware Specification No The paper does not provide specific details about the hardware used for running the experiments, such as GPU models, CPU types, or cloud computing instance specifications.
Software Dependencies No The paper mentions using the 'Adam optimizer' and specific neural network architectures like 'Wide-Res Net-28-10' and 'Res Net-50', but it does not specify version numbers for any software libraries (e.g., PyTorch, TensorFlow, CUDA) or programming languages used.
Experiment Setup Yes We first train the network on a subset of 4, 000 randomly selected samples from CIFAR-10. We then progressively update the policy network parameters θk (k = 1, 2, , K) for 512 iterations for each of the K augmentation layers. We use the Adam optimizer (Kingma & Ba, 2015) and set the learning rate to 0.025 for policy updating. The evaluation configurations are kept consistent with that of Fast Auto Augment. ...we use step learning rate scheduler with a reduction factor of 0.1, and we train and evaluate with images of size 224x224. ...The best found parameters are summarized in Table 8 in Appendix. (Table 8 provides Learning Rate, Weight Decay, Epoch for CIFAR-10/100 with Batch Augmentation).
