Learn how to find the unusual, interesting, extreme, or inaccurate parts of your data.Outliers can be the most informative parts of your data, revealing hidden insights, novel patterns, and potential problems. For a business, this can mean finding new products, expanding markets, and flagging fraud or other suspicious activity. Outlier Detection in Python introduces the tools and techniques you'll need to uncover the parts of a dataset that don't look like the rest, even when they're the more hidden or intertwined among the expected bits.In Outlier Detection in Python you'll learn how to:

Use standard Python libraries to identify outliers Pick the right detection methods Combine multiple outlier detection methods for improved results Interpret your results Work with numeric, categorical, time series, and text data

Outlier detection (OD) is a vital tool for everything from financial auditing to network security. OD techniques also work for testing datasets for quality, collection errors, and data drift. This unique guide introduces the core tools of outlier detection like scikit-learn and PyOD, the principal algorithms used in outlier detection, and common pitfalls you might encounter.

It's time we all stopped whining and learned a thing or two from The Toughest Cyclists Ever. Including:Stephen Roche, whose cure for exhaustion was to go up a gear and fight harder, all the way to the ambulance. Eddy Merckx, who hurt himself so badly in breaking the Hour record that, he estimated, he shortened his career by a year. Beryl Burton, who crushed her (male) rival's morale with the offer of a piece of liquorice, before speeding past to victory. Nicole Cooke and Edwig Van Hooydonck, who rejected dope and became legends.The Hardmen tells the stories - the good bits, anyway - of the 40 most heroic Cyclists ever. Their bravery, their panache and their Perfect Amount of Dumb. It reminds us that suffering on a bike liberates us from our daily lives, and that, in the words of Lance Armstrong "pain is temporary, quitting lasts forever"; proof that even assholes can be insightful.
