Computer scientists have invented a highly effective, yet incredibly simple, algorithm to decide which items to toss from a web cache to make room for new ones. Computer scientists have invented a ...

All mainstream credit card numbers obey a mathematical trick designed to catch the most common typos. It’s called the Luhn algorithm, named after IBM researcher Hans Peter Luhn, who patented it in ...

Data security is very important in data transmission. There are many methods to make the data to be secure. One of the methods is by using cryptography algorithm to encrypt the data. Using the ...

We leverage insights from machine learning to optimize the tradeoff between bias and variance when estimating economic models using pooled datasets. Specifically, we develop a simple algorithm that ...

The goal of a numerical optimization problem is to find a vector of values that minimizes some cost function. The most fundamental example is minimizing the Sphere Function f(x0, x1, .. xn) = x0^2 + ...

Recent progress in camera systems, image analysis, and machine learning have made optical-based gesture recognition a more attractive option in most contexts. However, current methods are hindered by ...

A logo for SIEVE, created by Yazhuo Zhang, portrays hotter objects in shades of red and colder ones in shades of blue. Zhang also designed a web site for SIEVE, including a motion graphic ...
