Computational Complexity and Information Asymmetry in Financial Products
Securitization of cash flows using financial derivatives transformed the financial industry over the last three decades. Derivatives have attracted criticism, but others say problems with derivatives would disappear with use of more accurate financial models, more vigilance by buyers and better governmental oversight.
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.
Crowdsourcing Systems on the World-Wide Web
The practice of crowdsourcing is transforming the Web and giving rise to a new field.
Technical Perspective: Patterns Hidden from Simple Algorithms
Is the number 9021960864034418159813 random? To my limited mind, the string appears random. Is there a way to use some formal mathematics to justify my naïveté?
Poly-Logarithmic Independence Fools Bounded-Depth Boolean Circuits
The question of determining which (weak) forms of randomness "fool" (or seem totally random to) a given algorithm is a basic and fundamental question in the modern theory of computer science. In this work we report progress on this question.
Technical Perspective: Liability Issues in Software Engineering
The paper by LeMétayer et al. addresses one technical issue in a large and serious problem in the production of mass-market software (MMSW), that of the lack of liability by the producers of this MMSW.
Liability Issues in Software Engineering: The Use of Formal Methods to Reduce Legal Uncertainties
This paper reports on the results of a multidisciplinary project involving lawyers and computer scientists with the aim to put forward a set of methods and tools to (1) define software liability in a precise and unambiguous way and (2) establish such liability in case of incident. The overall approach taken in the project is presented through an electronic signature case study. The case study illustrates a situation where, in order to reduce legal uncertainties, the parties wish to include in the contract specific clauses to define as precisely as possible the share of liabilities between them for the main types of failures of the system.

Technical Perspective: Concerto For Violin and Markov Model
In the opening of Sibelius' Violin Concerto, a soloist plays delicately. The orchestra responds in kind. As the piece progresses, soloist and orchestra alternatively perform the main motifs in increasing measures of power and virtuosity, leading to a stirring resolution.
A system for musical accompaniment is presented in which a computer-driven orchestra follows and learns from a soloist in a concerto-like setting. The system's connections with machine learning are highlighted, showing current weaknesses and new possible directions.
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 InvolvedCommunications 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.
