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.

Inference at testing time

The following code can be used to carry out inference on the unlabeled test data:

import keras
import numpy as np
import pandas as pd
import cv2
import os
import time
from sklearn.externals import joblib
import argparse

# Read the Image and resize to the suitable dimension size
def get_im_cv2(path,dim=224):
img = cv2.imread(path)
resized = cv2.resize(img, (dim,dim), cv2.INTER_LINEAR)
return resized

# Pre Process the Images based on the ImageNet pre-trained model Image transformation
def pre_process(img):
img[:,:,0] = img[:,:,0] - 103.939
img[:,:,1] = img[:,:,0] - 116.779
img[:,:,2] = img[:,:,0] - 123.68
return img

# Function to build test input data
def read_data_test(path,dim):
test_X = []
test_files = []
file_list = os.listdir(path)
for f in file_list:
img = get_im_cv2(path + '/' + f)
img = pre_process...
