Neural Network Projects with Python

Overview of this book

Neural networks are at the core of recent AI advances, providing some of the best resolutions to many real-world problems, including image recognition, medical diagnosis, text analysis, and more. This book goes through some basic neural network and deep learning concepts, as well as some popular libraries in Python for implementing them. It contains practical demonstrations of neural networks in domains such as fare prediction, image classification, sentiment analysis, and more. In each case, the book provides a problem statement, the specific neural network architecture required to tackle that problem, the reasoning behind the algorithm used, and the associated Python code to implement the solution from scratch. In the process, you will gain hands-on experience with using popular Python libraries such as Keras to build and train your own neural networks from scratch. By the end of this book, you will have mastered the different neural network architectures and created cutting-edge AI projects in Python that will immediately strengthen your machine learning portfolio.

MLPs

Now that we have completed exploratory data analysis and data preprocessing, let's turn our attention towards designing the neural network architecture. In this project, we will be using MLPs.

An MLP is a class of feedforward neural network, and it distinguishes itself from the single-layer perceptron that we've discussed in Chapter 1, Machine Learning and Neural Networks 101, by having at least one hidden layer, with each layer activated by a non-linear activation function. This multilayer neural network architecture and non-linear activation allows MLPs to produce non-linear decision boundaries, which is crucial in multi-dimensional real-world datasets such as the Pima Indians Diabetes dataset.
