WebNov 23, 2024 · The scratch version of AlexNet profits most from data augmentation. The reason is probably that it consists of most parameters to train and therefore larger datasets are very helpful. The fine-tuned CNN models hardly profit from data augmentation for the considered datasets. One reason is that the performances of the fine-tuned CNN … The third trick they used is data augmentation. We want our neural networks to generalize well, so, we augment our data by doing some simple operations and on-the-fly i.e. the augmented image is generated while training (just like in AlexNet). AlexNet uses image translations and horizontal reflection. Out of … See more Due to paucity of GPU memory at the time the network was designed, it had to be trained by combining 2 GPUs. 1. Our input is 224x224x3images. (In the paper, it is given 150,528-dimensional, which is a bit confusing) 2. Next, … See more This is one of the neat tricks they used.
