Transfer learning is a technique where you can use a neural network trained to solve a particular type of problem and with a few changes, you can reuse it to solve a related problem. To keep our dataset small, we will use 40% of the original training data (25,000 images) for training, 10% for validation, and 10% for testing. This lesson is part 2 of a 3-part series on advanced PyTorch techniques: Training a DCGAN in PyTorch (last week's tutorial); Training an object detector from scratch in PyTorch (today's tutorial); U-Net: Training Image Segmentation Models in PyTorch (next week's blog post); Since my childhood, the idea of artificial intelligence (AI) has fascinated me (like every other kid).
