Data augmentation pytorch shift

WebSep 27, 2024 · Now, if we augment the data on the fly (with random transformations) using PyTorch, then each epoch has the same number of iterations n. If we concatenate 5 epochs consécutive to create a large epoch (or call it whatever you want), then the total number of iterations in this large epoch is 5n. Thus it is roughly equivalent to static augmentation. WebAug 4, 2024 · 1 Answer. Sorted by: 1. A transformation will typically only be faster on the GPU than on the CPU if the implementation can make use of the parallelism offered by the GPU. Typically anything that operates element-wise, or row/column-wise can be made faster on GPU. This therefore concerns most image transformations.
