Chapter 5. Data Analysis – Correlation

Correlation is a good technique to use on your dataset. Correlation helps us to establish basic relationships between data items.

In this chapter, we look at tools available in R for correlation:

A basic correlation
Visualizing correlations
Covariance
Pearson correlation
Polychoric correlation
Tetrachoric correlation
A heterogeneous correlation matrix
Partial correlation

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.
