Convolutional neural networks are a class of neural network that resolve the high-dimensionality problem we alluded to in the previous section, and, as a result, excel at image-classification tasks. It turns out that image pixels in a given image region are highly correlated—they tell us similar information about that specific image region. Accordingly, using convolutional neural networks, we can scan regions of an image and summarize that region in lower-dimensional space. As we'll see, these lower-dimensional representations, called feature maps, tell us many interesting things about the presence of all sorts of shapes—from the simplest lines, shadows, loops, and swirls, to very abstract, complex forms specific to our data, in our case, cat ears, cat faces, or tortillas—and do this in fewer dimensions than the original...

Overview of this book
Machine learning is transforming the way we understand and interact with the world around us. This book is the perfect guide for you to put your knowledge and skills into practice and use the Python ecosystem to cover key domains in machine learning. This second edition covers a range of libraries from the Python ecosystem, including TensorFlow and Keras, to help you implement real-world machine learning projects.
The book begins by giving you an overview of machine learning with Python. With the help of complex datasets and optimized techniques, you’ll go on to understand how to apply advanced concepts and popular machine learning algorithms to real-world projects. Next, you’ll cover projects from domains such as predictive analytics to analyze the stock market and recommendation systems for GitHub repositories. In addition to this, you’ll also work on projects from the NLP domain to create a custom news feed using frameworks such as scikit-learn, TensorFlow, and Keras. Following this, you’ll learn how to build an advanced chatbot, and scale things up using PySpark. In the concluding chapters, you can look forward to exciting insights into deep learning and you'll even create an application using computer vision and neural networks.
By the end of this book, you’ll be able to analyze data seamlessly and make a powerful impact through your projects.
