Author John Myles White shows you how this powerful class of algorithms can help you boost website traffic, convert visitors to customers, and increase many other measures of success.This is the first developer-focused book on bandit algorithms, which were previously described only in research papers. You’ll quickly learn the benefits of several simple algorithms—including the epsilon-Greedy, Softmax, and Upper Confidence Bound (UCB) algorithms—by working through code examples written in Python, which you can easily adapt for deployment on your own website.Learn the basics of A/B testing—and recognize when it’s better to use bandit algorithmsDevelop a unit testing framework for debugging bandit algorithmsGet additional code examples written in Julia, Ruby, and JavaScript with supplemental online materials

    Why is Christ called the “Son of God”? Discover an answer so simple you’ll wonder why you never saw it before, and so beautiful it’ll take your breath away.

    Too bad her past won't return the favor. Ursula can't remember a single thing from before three years ago, so she has to keep her life simple. All she wants is to earn enough money for rent--and maybe a bit left over for a new pair of boots. But on her eighteenth birthday, all hell breaks loose... quite literally... when a hellhound shifter shows up in her kitchen. Kester's lethally gorgeous, and he's come with a terrifying message: Ursula owes her soul to a demon. No one seems to care that she doesn't remember striking that deal. Thrust into the middle of a war between the gods of fire and night, Ursula fights her way across New York--and through the fae realm--to survive. Along the way, she must reclaim her magical knowledge and her long-forgotten skills with the blade if she wants to escape eternal damnation. This boxed set contains all four books in the Shadows & Flame series. They're urban fantasy with lots of magic, romance, and intrigue.

    Distinguishing agents (e.g., molecules, cells, animals, and species) from their interactions (e.g., chemical reactions, immune system responses, sexual reproduction, and evolution), Flake argues that it is the computational properties of interactions that account for much of what we think of as beautiful and interesting. From this basic thesis, Flake explores what he considers to be today's four most interesting computational topics: fractals, chaos, complex systems, and adaptation.Each of the book's parts can be read independently, enabling even the casual reader to understand and work with the basic equations and programs. Yet the parts are bound together by the theme of the computer as a laboratory and a metaphor for understanding the universe. The inspired reader will experiment further with the ideas presented to create fractal landscapes, chaotic systems, artificial life forms, genetic algorithms, and artificial neural networks.

    A LISP "toolkit" in each chapter explains how to use Common LISP programming and debugging tools such as DESCRIBE, INSPECT, TRACE and STEP.

    Fans of Sheriff Walt Longmire will fall in love with Sergeant Maggie Blackthorne, the spirited protagonist with a tragic past and an acid wit.When Maggie Blackthorne returns to her hometown after nearly twenty years to serve as an Oregon State Police Sergeant, she expects to deal with the usual suspects — drunk drivers, oxy slingers, and the occasional rural scofflaw.But after she stumbles upon the bullet-ridden bodies of twin brothers, she realizes she’s stepped into something much more sinister. With little homicide experience, Maggie and her partner, Trooper Hollis Jones, find themselves thrust into a murder investigation.And when a third man turns up dead, the pair fears it’s only a matter of time before the killer strikes again. As they race to piece together what happened, Maggie and Hollis discover a tangled web of theft, deceit and deals gone bad.Faced with multiple motives and several persons of interest, Maggie and Hollis finally catch a break — but are they willing to risk everything to put the murderer behind bars?
