O’Neil elaborated on a topic she discussed in her book Weapons of Math Destruction — her belief that big data increases inequality and acts as a threat to democracy. “Facebook and Google have so much ...

The key to a solid foundation in data structures and algorithms is not an exhaustive survey of every conceivable data structure and its subforms, with memorization of each's Big-O value and ...

In 1960, a 23-year-old Soviet mathematician named Anatoly Karatsuba stunned the world of mathematics with a revolutionary ...

Big-O, Big-Omega, Big-Theta notations, and their meanings. Basic data structures: Heaps, and Binary Search Trees. Algorithm Design Approaches: Divide and Conquer including analysis using recurrences ...

This tutorial launches a short series introducing data structures and algorithms. In Part 1, you’ll learn what a data structure is and how data structures are classified.

Recall that O (1) is pronounced “Big Oh of 1.” (See Part 1 for a reminder of how time and space complexity measurements are used to evaluate data structures.) ...

Cathy O'Neil, a data scientist and founder of ORCAA Algorithmic Auditing, had a message for the audience at the 2017 TED talks: "We need to demand accountability from our algorithmic overlords." ...

The age of Big Data has generated new tools and ideas on an enormous scale, with applications spreading from marketing to Wall Street, human resources, college admissions, and insurance.

O’Neil is a former hedge-fund quant (a mathematician who creates algorithms to help traders make money) who left Wall Street and wrote a book: “Weapons of Math Destruction: How Big Data ...
