Intelligent Projects Using Python

By: Santanu Pattanayak

Overview of this book

This book will be a perfect companion if you want to build insightful projects from leading AI domains using Python. The book covers detailed implementation of projects from all the core disciplines of AI. We start by covering the basics of how to create smart systems using machine learning and deep learning techniques. You will assimilate various neural network architectures such as CNN, RNN, LSTM, to solve critical new world challenges. You will learn to train a model to detect diabetic retinopathy conditions in the human eye and create an intelligent system for performing a video-to-text translation. You will use the transfer learning technique in the healthcare domain and implement style transfer using GANs. Later you will learn to build AI-based recommendation systems, a mobile app for sentiment analysis and a powerful chatbot for carrying customer services. You will implement AI techniques in the cybersecurity domain to generate Captchas. Later you will train and build autonomous vehicles to self-drive using reinforcement learning. You will be using libraries from the Python ecosystem such as TensorFlow, Keras and more to bring the core aspects of machine learning, deep learning, and AI. By the end of this book, you will be skilled to build your own smart models for tackling any kind of AI problems without any hassle.

Building the model

We will build a simple LSTM version of the recurrent neural network, with an embedding layer following the input layer. The embedding layer word vectors are initialized with the pretrained Glove vectors with a dimension of 100, and the layer is defined as trainable, so that the word vector embedding can update itself based on the training data. The dimension of the hidden states and the cell states is also kept as 100. The model is trained using binary cross-entropy loss. To avoid overfitting, ridge regularization is added to the loss function. The Adam optimizer is used for training the model.

The following code snippet shows the function used to build the model in TensorFlow:

def _build_model(self):

with tf.variable_scope('inputs'):
self.X = tf.placeholder(shape=[None, self.sentence_length],dtype=tf.int32,name="X&quot...
