Overview of this book

Thanks to a number of recent breakthroughs, self-driving car technology is now an emerging subject in the field of artificial intelligence and has shifted data scientists' focus to building autonomous cars that will transform the automotive industry. This book is a comprehensive guide to use deep learning and computer vision techniques to develop autonomous cars. Starting with the basics of self-driving cars (SDCs), this book will take you through the deep neural network techniques required to get up and running with building your autonomous vehicle. Once you are comfortable with the basics, you'll delve into advanced computer vision techniques and learn how to use deep learning methods to perform a variety of computer vision tasks such as finding lane lines, improving image classification, and so on. You will explore the basic structure and working of a semantic segmentation model and get to grips with detecting cars using semantic segmentation. The book also covers advanced applications such as behavior-cloning and vehicle detection using OpenCV, transfer learning, and deep learning methodologies to train SDCs to mimic human driving. By the end of this book, you'll have learned how to implement a variety of neural networks to develop your own autonomous vehicle using modern Python libraries.

Building and compiling our model

We have already read about building and compiling models in Chapter 3, Implementing a Deep Learning Model Using Keras. Let's build a simple neural network, and then we will start building the model. In this section, we will add the layers to be used in our deep learning model:

  1. We will first import the important libraries from Keras:
import tensorflow as tf
from tensorflow import keras
from tensorflow.keras import layers
  1. Let's design the CNN with the following code. We add our first layer as the convolution layer with a filter of 32, kernal_size set to (3,3), and ReLU as our activation function. Then, we add a convolution layer with a filter value of 64 with ReLU as our activation function. Then, we added a maxpooling layer. Finally, we drop out and flatten a dense layer with a filter size of 128 and our ReLU activation function. Finally, we add one more dropout layer:
model = tf.keras.Sequential()

model.add(tf.keras.layers.Conv2D(10, kernel_size...
