An algorithm is a set of instructions that allows you to solve a problem.

Each instruction is simple and repeatable. It’s important to understand that the instructions work on all similar problems, not just one.

Here’s an algorithm for sorting any set of numbers, to get them into order. Start with 4,3,5,6,2 for example.

The bubble sort algorithm is simple. Compare two numbers. If the first number is higher than the second, switch them. So now it’s 3,4,5,6,2. Next step is to compare positions two and three. If the second is higher than the third (it’s not) switch them. Repeat for the whole string. Then start over. Do it over and over again until you can go the whole way with no switching. Done.

About nine out of 10 US consumers ages 12 to 24 use the Internet. That is not surprising. But more than one-half of those ages 65 to 69 are online as well, and Internet-using 70-to-74-year-olds make up 45% of people that age, according to the Pew Internet & American Life Project.

Pew noted that the biggest increase in Internet use since 2005 was in the 70-to-75-year-old age group; just over one-quarter of them were online in 2005.

Data mining in the credit crisis

Posted in Analytics, Business Intelligence, Data Mining, NYTimes by Pankaj Gudimella on February 2, 2009

In recent months, American Express has gone far beyond simply checking your credit score and making sure you pay on time. The company has been looking at home prices in your area, the type of mortgage lender you’re using and whether small-business card customers work in an industry under siege. It has also been looking at how you spend your money, searching for patterns or similarities to other customers who have trouble paying their bills.
