This Algorithm Can ‘Remove’ The Water From Underwater Photos With Stunning Results – Ubergizmo

This Algorithm Can ‘Remove’ The Water From Underwater Photos With Stunning Results – Ubergizmo

We’re not sure how many of you take photos while underwater, but underwater photos is a pretty common thing, especially amongst those who enjoy diving and love documenting their dives and also capturing photos of sealife. However, one of the problems with underwater photography is that sometimes the water can add an unnecessary hue to…

A neural algorithm for a fundamental computing problem

A neural algorithm for a fundamental computing problem

Fly brain inspires computing algorithmFlies use an algorithmic neuronal strategy to sense and categorize odors. Dasgupta et al. applied insights from the fly system to come up with a solution to a computer science problem. On the basis of the algorithm that flies use to tag an odor and categorize similar ones, the authors generated…
A health care algorithm affecting millions is biased against black patients

A health care algorithm affecting millions is biased against black patients

A health care algorithm makes black patients substantially less likely than their white counterparts to receive important medical treatment. The major flaw affects millions of patients, and was just revealed in research published this week in the journal Science. The study does not name the makers of the algorithm, but Ziad Obermeyer, an acting associate…
How an Algorithm Favored Whites Over Blacks for Health Care

How an Algorithm Favored Whites Over Blacks for Health Care

Care for some of the sickest Americans is decided in part by algorithm. New research shows that software guiding care for tens of millions of people systematically privileges white patients over black patients. Analysis of records from a major US hospital revealed that the algorithm used effectively let whites cut in line for special programs…

The Paxos Algorithm, or How to Win a Turing Award

Leslie Lamport Last modified on 23 August 2019 In July 2019 I gave a pair of 1-1/2 hour lectures at a summer school on distributed computing in Saint Petersburg, Russia.  The lectures covered three topics: The Paxos consensus algorithm. TLA+ How to win a Turing award. If you are interested in any of those topics,…
This hand-tracking algorithm could lead to sign language recognition

This hand-tracking algorithm could lead to sign language recognition

Millions of people communicate using sign language, but so far projects to capture its complex gestures and translate them to verbal speech have had limited success. A new advance in real-time hand tracking from Google’s AI labs, however, could be the breakthrough some have been waiting for. The new technique uses a few clever shortcuts…
Hidden Algorithm Flaws Expose Websites to DoS Attacks

Hidden Algorithm Flaws Expose Websites to DoS Attacks

This week, the notorious forum 8chan went down after its infrastructure provider Cloudflare withdrew its services over the forum's radical, violence-promoting content. Cloudflare didn't shut the site down directly, but by removing its protection against distributed denial of service attacks, it could all but guarantee that the forum would crash. But while the classic types…
Faster algorithm could lead to more realistic sounds in VR – Engadget

Faster algorithm could lead to more realistic sounds in VR – Engadget

The solution ultimately involved ditching the traditional approach to calculating sound propagation, which has its roots in the theories of pioneering scientist Hermann von Helmholtz. Instead, the scientists took their cue from composer Heinrich Klein's ability to blend many piano notes into a single sound. It splits vibration modes into individual chords, then performs a…
