CNNs trained from scratch lag significantly behind pretrained models

An experiment comparing two Convolutional Neural Networks (CNNs) on the Food-101 dataset revealed the significant advantage of using pretrained weights. TinyVGG, trained from scratch, achieved only 23% accuracy after 30 epochs, while ResNet50, utilizing pretrained weights from ImageNet and only training a classifier head, reached over 65% accuracy in the same timeframe. The initial training epoch showed a stark difference, with TinyVGG at 2% and ResNet50 at 52% accuracy, highlighting the value of prior knowledge embedded in pretrained models. AI

IMPACT Demonstrates the critical importance of transfer learning and pretrained weights in achieving high performance in image classification tasks.
