First published in 1916. According to the Preface: " Having been connected for many years with two of the largest and most successful private detective agencies in this country, both as an operator and as an official, and having been requested to outline briefly and concisely the most modern and up-to-date methods employed by leading detectives and private detective agencies of today, I shall confine myself in these pages to facts and a few personal experiences. I will endeavor to show that any person possessed of average intelligence, and who will use good common sense, can become a successful detective, regardless of his present or previous occupation."

First published in 1920. Job opportunities in aviation soon after World War I. "Any ordinary, active man, provided he has reasonably good eyesight and nerve, can fly, and fly well. If he has nerve enough to drive an automobile through the streets of a large city, and perhaps argue with a policeman on the question of speed limits, he can take himself off the ground in an airplane, and also land—a thing vastly more difficult and dangerous. We hear a great deal about special tests for the flier—vacuum-chambers, spinning-chairs, co-ordination tests—there need be none of these. The average man in the street, the clerk, the laborer, the mechanic, the salesman, with proper training and interest can be made good, if not highly proficient pilots. If there may be one deduction drawn from the experience of instructors in the Royal Air Force, it is that it is the training, not the individual, that makes the pilot."

Saint Smith and Other Stories consists of two novellas and six short stories. "Saint Smith" focuses on Charlie, a would-be experimental film maker, Sarah his traditional Bible-believing mother, and Irene the clever ironic uninhibited German woman he marries. "The Barracks" takes place in basic training at Fort Polk, Louisiana, at the time of the Viet Nam War. The six stories deal with puzzles of human nature and the meaning of life.

Classic Western. According to Wikipedia: "Zane Grey (1872 – 1939) was an American author best known for his popular adventure novels and stories that presented an idealized image of the rugged Old West. As of June 2007, the Internet Movie Database credits Grey with 110 films, one TV episode, and a series, Dick Powell's Zane Grey Theater based loosely on his novels and short stories."

Three classic Christas stories: The Birds' Christmas Carol, The Romance of a Christmas Card, and The Old Peabody Pew. According to Wikiipedia: "Kate Douglas Wiggin (September 28, 1856–August 24, 1923) was an American children's author and educator. Kate Douglas Smith Wiggin was born in Philadelphia, and was of Welsh descent. A graduate of Abbot Academy, Class of 1873, she started the first free kindergarten in San Francisco in 1878 (the Silver Street Free Kindergarten). With her sister in the 1880s she also established a training school for kindergarten teachers... Still devoted to her school, she began to raise money for it through writing, first The Story of Patsy (1883), then The Birds' Christmas Carol (1887). Both privately printed books were issued commercially by Houghton Mifflin in 1889, with enormous success. Ironically, considering her intense love of children, Kate Wiggin had none. Her husband died suddenly in 1889, and Kate took her grief home to Maine. For the rest of her life she struggled with depression, and in order to combat it she traveled as frequently as she could, dividing her time between writing, trips to Europe, and giving public reading for the benefit of various children's charities. Her literary output included popular books for adults, scholarly work on the educational principles of Friedrich Froebel, and of course the classic children's novel Rebecca of Sunnybrook Farm (1903) Wiggin's home in the Salmon Falls section of Hollis, Maine."

Neural Networks and their implementation decoded with TensorFlow About This Book Develop a strong background in neural network programming from scratch, using the popular Tensorflow library. Use Tensorflow to implement different kinds of neural networks – from simple feedforward neural networks to multilayered perceptrons, CNNs, RNNs and more. A highly practical guide including real-world datasets and use-cases to simplify your understanding of neural networks and their implementation. Who This Book Is For This book is meant for developers with a statistical background who want to work with neural networks. Though we will be using TensorFlow as the underlying library for neural networks, book can be used as a generic resource to bridge the gap between the math and the implementation of deep learning. If you have some understanding of Tensorflow and Python and want to learn what happens at a level lower than the plain API syntax, this book is for you. What You Will Learn Learn Linear Algebra and mathematics behind neural network. Dive deep into Neural networks from the basic to advanced concepts like CNN, RNN Deep Belief Networks, Deep Feedforward Networks. Explore Optimization techniques for solving problems like Local minima, Global minima, Saddle points Learn through real world examples like Sentiment Analysis. Train different types of generative models and explore autoencoders. Explore TensorFlow as an example of deep learning implementation. In Detail If you're aware of the buzz surrounding the terms such as "machine learning," "artificial intelligence," or "deep learning," you might know what neural networks are. Ever wondered how they help in solving complex computational problem efficiently, or how to train efficient neural networks? This book will teach you just that. You will start by getting a quick overview of the popular TensorFlow library and how it is used to train different neural networks. You will get a thorough understanding of the fundamentals and basic math for neural networks and why TensorFlow is a popular choice Then, you will proceed to implement a simple feed forward neural network. Next you will master optimization techniques and algorithms for neural networks using TensorFlow. Further, you will learn to implement some more complex types of neural networks such as convolutional neural networks, recurrent neural networks, and Deep Belief Networks. In the course of the book, you will be working on real-world datasets to get a hands-on understanding of neural network programming. You will also get to train generative models and will learn the applications of autoencoders. By the end of this book, you will have a fair understanding of how you can leverage the power of TensorFlow to train neural networks of varying complexities, without any hassle. While you are learning about various neural network implementations you will learn the underlying mathematics and linear algebra and how they map to the appropriate TensorFlow constructs. Style and Approach This book is designed to give you just the right number of concepts to back up the examples. With real-world use cases and problems solved, this book is a handy guide for you.
