Technical Perspective: Images Everywhere Looking For Models

About 5,000 images per minute are uploaded to the photo-sharing site http://www.flickr.com/; over 7,000,000 a day. Such images often look noisy, blurry, and with the wrong colors or contrast.

Technical Perspective: Complex Financial Products: <i>Caveat Emptor</i>

CDOs are examples of financial derivatives, with a value that depends on the underlying assets with which they are linked. These kinds of complex financial products are the cause célèbre of the financial crisis, and many have called for their regulation or even elimination.

Self-Similarity-Based Image Denoising

The search for efficient image denoising methods is still a valid challenge at the crossing of functional analysis and statistics. In spite of the sophistication of the recently proposed methods, most algorithms have not yet attained a desirable level of applicability.

Embracing Noise or Why Computer Scientists Should Stop Worrying and Learn to Love the Errors

Precision is not required in everything or even most things. Failures are best handled by expecting them all the time, not treating them as exceptions. We should expect errors and handle them routinely. We should stop worrying and learn to love the noise.

Intellectual Amplification via Computing

As the recent performance of IBM's Watson system on the game show Jeopardy! illustrated, the combination of large-scale data, rich algorithm suites and powerful computing are opening new vistas. Vannevar Bush's 1940s vision of a Memex, a device capable of storing, indexing and retrieving data from a broad knowledge base, is now within our reach.

DRAM Errors in the Wild: A Large-Scale Field Study

While a large body of work exists on DRAM in lab conditions, little has been reported on real DRAM failures in large production clusters. In this paper, we analyze measurements of memory errors in a large fleet of commodity servers over a period of 2.5 years.

Technical Perspective: DRAM Errors in the Wild

In order to advance the field, knowledge of the types of memory errors at the system level, their frequencies, and conditions that exacerbate or are unrelated to higher error rates are of critical importance.

Shape the Future of Computing

ACM encourages its members to take a direct hand in shaping the future of the association. There are more ways than ever to get involved.

Get Involved

Communications of the ACM (CACM) is now a fully Open Access publication.

By opening CACM to the world, we hope to increase engagement among the broader computer science community and encourage non-members to discover the rich resources ACM has to offer.
