Reshaping with pd.DataFrame.stack and pd.DataFrame.unstack

Before we jump into the terms stacking and unstacking, let’s take a step back and compare two tables of data. Do you notice anything different about:

	a	b	c
x	1	2	3
y	4	5	6

Table 7.1: A table in wide format

compared to:

x	a	1
x	b	...

Modern Computer Vision with PyTorch

Modern Computer Vision with PyTorch

This book provides a hands-on approach to solving over 30 prominent real-world computer vision problems using PyTorch 2.x on actual datasets. Here you'll learn to build a neural network from scratch and optimize hyperparameters, perform image classification, multi-object detection, segmentation, and more. You'll also explore facial expression manipulation and combining CV with NLP and RL techniques, build generative AI applications, and take your model to production on AWS. By the end of this book, you'll master modern NN architectures and confidently solve real-world CV problems.
