Plagiarism: everything but the title

[Update: another plagiarism detected on 2014/12/29; This post originated from Grégory Favre news on the excellent EPFL Infodoc mailing list, and concerns to EPFL papers]

The pressure of publication pushes back the frontiers of laziness. Here, a sole change in a paper title allows the paper to pass through reviews (if there are any reviews in this case, look at Nuit Blanche on peer review).

If you steal from one author it's plagiarism; if you steal from many it's research. (attributed to Wilson Mizner)
The most interesting example i had seen so far was a paper i reviewed on nonsubsampled contourlets (a kind of discretized, directional wavelet). It was entitled "A New Image Denoising Scheme using the Nonsubsampled Contourlet Transform", and  submitted in 2008 to Signal Processing by three authors from one of the two most populated countries in the world. Its content had about 60% overlap with a more standard and authoritative paper on the topic. A big difference reside…

Conference: Fixing mathematical education

[Permission to link to author slides is being asked. Stay tuned, but do not expect too much] Meanwhile, check out Simon Leys (aka Pierre Rickmans) "Le studio de l'inutilité" (or The Hall of uselessness), with a special attention to Leys' talk on 8 Nov. 2005 at l'Université catholique de Louvain, with its nice quote to Flaubert: "I have always tried to live in an ivory tower; but a tide of shit is beating at its walls, threatening to undermine it."

"Modeling is a life skill" (Solomon Garfunkel)
"To be able to use maths at a certain level, it is necessary to learn it at the next level" (Alexandre Borovik)

On April 4h, 2012, a meeting held in IHP, Paris. Under the motto: How to fix our math education (Comment réparer l’enseignement des mathématiques ?). The main incentive was Solomon GARFUNKEL (COMAP Inc., Boston) and David MUMFORD (Brown University) paper "How to fix our math education", New York Times, August 28th, 2011. The p…

Hyperbolets (on WITS: Where is the Starlet)

A new conference is born: UCCV 2013, The 1st IEEE Workshop on User-Centred Computer Vision, due in Florida, Tampa. on January 2013. It has been added to SIVA Conferences.

While the shearlets are enjoying some spread (cf. Shearlets from MIA 2012 or this paper), some of their contributors are involved in hyperbolets, or hyperbolic wavelets, closely related cousins. Here they are (as on WITS: where is the Starlet):
HyperboletsIn short:An example of multi-composite wavelets with hyperbolic scaling lawEtymology:From the hyperbola (wiki entry), with a potential reference (article no available on 2011/05/26) to the parabolic scaling law of the shearletsOrigin:Glenn R. Easley, Demetrio Labate, Vishal M. Patel: Multi-composite wavelet estimation, Proceedings of SPIE Volume 8138, Wavelets and Sparsity XIV, Aug. 2011 (local copy)
Abstract: In this work, we present a new approach to image denoising by using a general representation known as wavelets with composite dilations. These representati…

Dry signal processing:: DATs to FIGs

Signal Processing is very akin to dry fruits: this is the very art of transforming .DAT 's in .FIG 's!/laurentduval/status/192746543349108736

Only that? Sure.
