Kebab principle: digital mafia

[Post to be continued later, I'm just marking space]

I developed the Kebab principle in Strasbourg (Alsace, France), lunching excellent kebabs (with Rotekohl) in Pamukalle II.

I elaborated on the Digital Mafia in another and more gourmet Kebab restaurant in Paris: rue du Paradis, in one Our Kebab franchise (Grand Paris, France).

Stay tuned (teaser)

Kultur Pop 49 : syzygy

Kultur Pop ? Il s'agit de compilations de génériques musicaux d'émissions de radio (surtout culturelles, France Culture/France Inter, et parfois des intruses), émissions et musiques qui m'ont influencées. 


L
e 49e volume de génériques radiophoniques Kultur Pop, vient donc de paraître. Il est nommé "Syzygy". Cela faisait plusieurs confinements depuis le numéro 48, et tous les précédents disponibles sur "La vertu d'un LA : Kultur Pop". Coïncidence, il contient un morceau du EP de Saycet :
"One Day At Home".

 Kultur Pop 49 "Syzygy" se place sous le signe de la science, dans une conjonction (syzygy ou syzygie). Celle du décès de Michel Alberganti (producteur de radio, journaliste et écrivain) qui anima notamment la passionnante émission "Science-Friction" sur France Culture. Et celle du prix AJSPI (Association des journalistes scientifiques de la presse d’information) du meilleur journaliste scientifique de l'année 2021 décerné au journaliste scientifique Nicolas Martin (avec notamment : Radiographie du coronavirus, Les idées Claires, La Méthode Scientifique).

Tandis :

  • que le rayon de la pandémie s’accroît,
  • que le volume de la crédibilité dite scientifique se dissipe dans les vapeurs vaccinales,
  • que toute attestation atteste de la fragilité attestant les propos ci-dessus,

nous écouterons :

  • Kultur Pop #49-01 Juke-Box (ex-Métronomique), France Culture : David Axelrod, Holy Thursday 
  • Kultur Pop #49-02 Science Friction, fin, France Culture : Readymade FC (Jean-Philippe verdin) Interlude 01 
  • Kultur Pop #49-03 De beaux lendemains - début, France Culture : O. Lamm, Kopavogur Revisited & Tennis / Piano In Kyoto
  • Kultur Pop #49-04 Heureux qui comme Ulysse (France Inter) et La démarche scientifique, Le journal des sciences (France Culture) : Saycet, Chromatic bird

Hurricane Turtle: AA (the Word is a World)

From ancient traditions, the hurricane turtle was the world. Since recent outcrops, Hurricane Turtle is the word. A band with no less than Pierre Cherbero (Chant / Orgue), Seb "iep" Arruti (Trombone), Sylvain Téjérizo (Saxophone), Julien Dubois (Basse), Olivier Léani (Batterie). No more. 

They just released AA. A beginning. A gambling song:


Lyrics are here. They are:


#Song: AA

I used to play cards as a loving game
Cupidon strikes me right on time
In front of me the victime is a lame
He’s gonna fall on the magician that I am

I’m a gambler not a lover 
My rocket looks like the better
My deck is full of red hearts
But you know, he won’t see coming that part

AA got bullets in my hands now
All-In, what you gonna do now
AA got bullets with my aces now
I’m All-In cut it out

(Solo Saxophone)

Did I dream what I just saw there
The mo-fo kept the seven and a two for a full
My aces are just ashamed and he calls it
My finger on a trigger that I pull

AA got bullets in my hands now
All-In, what you gonna do now
AA got bullets with my aces now
I’m All-In cut it out

(Solo Trombone)

AA got bullets in my hands now
All-In, what I’m gonna do now
AA feel just like a fish now
Got myself the sneakiest bad beat!

(Theme)

Take it on, boys

SPOQ: norm ratio sparsity restoration (how I discovered sparsity and stopped worrying about it)

[TL;DR] How I discovered sparsity and stopped worrying about it

This is a journey into sparsity. The story started in 2009, in the South of France, and the nice island of Porquerolles. Here, clear blue water.

France, Porquerolles, plage Notre-Dame    
 
There was a workshop organized in June called Porquerolles 2019: Approximation and optimization in image restoration and reconstruction. A bunch of first class researchers were there: 
Amel Benazza-Benyahia, Jérôme Bolte, Antonin Chambolle, Caroline Chaux, Philippe Ciuciu, Albert Cohen, Patrick Louis Combettes, Claude Comtat, Christine de Mol, Alvaro R. De Pierro, Michel Defrise, Ron DeVore, Jalal Fadili, Mario Figueiredo, Massimo Fornasier, Jacques Froment, Yves Goussard, Gabor Herman, Jérome Idier, Dirk Lorenz, Russell Luke, Francois Malgouyres, Pierre Maréchal, Ali Mohammad-Djafari, Stanley Osher, Valérie Perrier, Jean-Christophe Pesquet, Gabriel Peyré, Aleksandra Pizurica, Andrew Reader, Elena Resmerita, Marc Sigelle, Gabriele Steidl, Marc Teboulle, Joel Trussell, Michael Unser, Dimitri Van de Ville, Isao Yamada
The program was wonderful. The trade-off between sea, science and sun was so easy. At that time, I had been working mostly with signals and images, processing them with sparsity-promoting decompositions: complex orthogonal/biorthogonal dual-tree wavelets with interesting covariance properties able at multichannel/multicomponent image denoising, tighly oversampled complex filter banks. We wanted to have data become sparser through a projection on some vector basis, union of bases or frames. Yet, what sparsity really meant was not fully clear to me. The count measure $\ell_0$ of course, but it is not practically usable for several reasons. 



[TO BE CONTINUED, THEN MATERIALS]

So: SPOQ means, in Swedish, "Svenskt Pediatriskt Ortopediskt Qvalitetsregister(Swedish Pediatric Orthopaedic Quality register)

And Mr SPOQ (at BandCamp, and...) is a german electronic music artist (from Aschaffenburg, Germany) as well. In his Cinnamon album, there is a tune called "Distance" (at BandCamp). And mathematically speaking, norms and distances are somewhat related.

But how does all the above relate to our SPOQ (SPOQ Lp-Over-Lq Regularization for Sparse Signal Recovery applied to Mass Spectrometry) algorithm? Later, it is way too late. 


L0 sparsity count index, L1-norm non-smooth convex proxy, L1/L2-norm ratio and Lp/Lq quasinorm/norm ratio smooth non-convex penalties.


Abstract: Underdetermined or ill-posed inverse problems require additional information for sound solutions with tractable optimization algorithms. Sparsity yields consequent heuristics to that matter, with numerous applications in signal restoration, image recovery, or machine learning. Since the 
0

 count measure is barely tractable, many statistical or learning approaches have invested in computable proxies, such as the 1
 norm. However, the latter does not exhibit the desirable property of scale invariance for sparse data. Generalizing the SOOT Euclidean/Taxicab 1
/
2
 norm-ratio initially introduced for blind deconvolution, we propose SPOQ, a family of smoothed scale-invariant penalty functions. It consists of a Lipschitz-differentiable surrogate for p
-over-
q
 quasi-norm/norm ratios with p]0,2[
 and q2
. This surrogate is embedded into a novel majorize-minimize trust-region approach, generalizing the variable metric forward-backward algorithm. For naturally sparse mass-spectrometry signals, we show that SPOQ significantly outperforms 0
1
, Cauchy, Welsch, and \celo penalties on several performance measures. Guidelines on SPOQ hyperparameters tuning are also provided, suggesting simple data-driven choices.

  • Chants des confins, jour 72 : Frankie Goes To Hollywood - Welcome to the pleasure dome
Life goes on days after day, the animals are winding me up, the jungle call
Shooting stars never stop, even when they reach the top
One of these days 
I'm going to cut you into little pieces
  • Chants des confins, jour 70 : Télépopmusik - Breathe
Another day, Just believe
Another day, Just breathe

No trouble, no trouble in thy breast
  • Chants des confins, jour 68 : Villagers of Ioannina City - Age Of Aquarius

  • Chants des confins, jour 65 : Mano Negra - Sidi'h'Bibi (album et live Chez Les Nuls L'Émission)
Ana m'rid ana m'rid
Hata m'rid mabia
And my skin was cool, And my heart sang
And when I said to myself that I will never go down

And there's a weepy old willow
He really knows how to cry
See the blind man shooting at the world
Bullets flying, oo-ooh taking toll
  • Chants des confins, jour 61 : The Kyteman Orchestra - PaDaDe (The Jam Sessions)
PaDaDe, PaDaDe, PaDaDe, PaDaDe, PaDaDe, PaDaDe, 
Part of the point in me doesn't know where to go, what I guess, it is all, just a show
  • Chants des confins, jour 60 : Dominique A (puis Alain Bashung) - Immortels
Avais-tu deviné que des dieux se cachaient

Surely I'm a pionner
Constellations stay the same

La station en verticale
Pour tout vous dire c'est un fiasco
With love
  • Chants des confins, jour 54 : Sting - Fragile (Pat Metheny, Nils Landgren, Esbjörn Svensson, Michael Brecker, Lars Danielsson, Wolfgang Haffner; Jazz Baltica 2003)

  • Chants des confins, jour 52 : Ilene Barnes- Times
Do you ever go to shows
With their eyes to see?

  • Chants des confins, jour 51 : Marillion - Incubus
[and the other lyrics]
You who wiped me from your memory like a greasepaint mask, Just like a greasepaint mask
But now I'm the snake in the grass, the ghost of film reels past

But was that love in your eye I saw or the reflection of mine?
I'll never really know for sure, you never really gave me time
Darkness encloses
And the candle seems to expire
It's gonna be everything you've ever dreamed
It's gonna be who

  • Chants des confins, jour 47 : Osiris - Is It Time (rare Bahrain progressive rock)
People are faces that rarely smile
It's dark, but the brightness is blinding
See the blind man
Shooting at the world
Did you see the redness block your part?
Did the scissors cut a way to your heart?
Through the ages she's heading west
From far away

  • Chants des confins, jour 43 : Suzanne Vega - Luka
I think it's because I'm clumsy
I try not to talk too loud
A reclining figure, Made of brass and steel
It's a perfect mixture, How I think and feel
But how can we still be friends
When seeing you only breaks my heart again?
Die Zeit ist reif für ein bisschen Zärtlichkeit
Irgendwie irgendwo irgendwann
Stand by to stand by
Ain't no need to worry today
A bottle of whisky, And a new set of lies
Blinds on a window, And a pain behind the eyes
  • Chants des confins, jour 37 :  Microfilm - Dpt4
Witness Flight Lieutenant William Terrance Decker, Royal Flying Corps, returning from a patrol somewhere over France. The year is 1917. The problem is that the Lieutenant is hopelessly lost.
Lieutenant Decker will soon discover that a man can be lost not only in terms of maps and miles, but also in time, and time in this case can be measured in eternities. [Lyrics from the Twilight Zone, teleplay by Richard Matheson]
Vous pouvez m'appeler la nuit chez moi [...]
J'ai mangé, et j'ai eu envie de pleurer
A new warmth stirs within the center of the earth
I am alone here no more

The clock
Tik-tok
  • Chants des confins, jour 33 : Barclay James Harvest - 1978 Live Tapes, Mockingbird
There's a mocking bird
Singing songs in the trees
  • Chants des confins, jour 32 : Nancy Sinatra & Lee Hazlewood - Summer Wine
I walked in town on silver spurs that jingled to
A song that I had only sang to just a few
See the beast, choose the truth, follow your instinct
Cross the threshold, be an animal again

Freak out
I move with the crowd
It might be to late, To change where we're goin'
But in your own mind, You can always be free
Word are flowing out like and less rain into a paper cup,
They slither while they pass, they sleep across the Universe. [Jai Guru Deva Om: glory to the shining remover of darkness]
Ad te suspiramus, gementes et flentes in hac lacrimarum valle.
Eia, ergo, advocata nostra, illos tuos misericordes oculos ad nos converte.
  • Chants des confins, jour 26 : Yaron Herman - No Surprises (#Radiohead cover)
Bring down the government
They don't, they don't speak for us
  • Chants des confins, jour 25 : Samaris - Góða Tungl (from Steingrímur Þorsteinsson)
Góða tungl um loft þú líður,
Ljúft við skýja silfur skaut.
  • Chants des confins, jour 24 : Bel Canto (with the beautiful voice of Anneli Drecker) - Rumour
I bless the sunshine and no shadows haunt my walls
Blue is a state of mind, Blue makes you colourblind


  • Chants des confins, jour 23 : Sinéad O'Connor (and The Chieftains) - Factory Girl
Going back to the factory
Their work to begin

When the dog bites, When the bee stings
When I'm feeling sad, I simply remember my favorite things
[This multi-instrumentalist is so expressive that she makes me feel she sings]
[And she does. Titles are self-explanatory]

[Quote attributed to Plato: "We can easily forgive a child who is afraid of the dark;
the real tragedy of life is when men are afraid of the light."]
Now he rode East and he rode West, He rode North and South also
Until he came to a wide open plain, It was there that he spied his lady-o
We promised the world we'd tame it, what were we hoping for?
A sense of purpose and a sense of skill, a sense of function but a disregard
Dans les ruines de l'école où brûle un tableau noir
Une craie s'est brisée en écrivant : espoir. Kill the kid
[Instrumental. Title from an Greek legend about someone who buried a treasure after being defeated. The Oracle of Delphi advised researchers to look under every stone]
"(Toilet) Paper late!" cried a voice in the crowd
"Old man dies!" The note he left was signed 'Old Father Thames'
April, come she will, May, she will stay.
June, she'll changed her tune,  July, she will fly.
Yes ready for sorrow, And ready to suffer
Yes ready to fight 'til death

[Instrumental. Comment from Ernest Melton: "But it’s really a message to myself that, at the end of the day, I don’t have to be a slave to trivial stuff in my life. That’s all it is."]
(version instrumentale)
Neventi vad d'ar Vretoned! [Heureuse nouvelle aux Bretons !]
Ha malloz-ru d'ar C'hallaoued! [Et malédiction rouge aux Français !]
From Big West
That never change
Yes, I love the ground on where he goes
And still I hope

Aamulla varhain kun aurinko nousi (Early in the morning when the sun rose)
Yö oli kaunis ja äänesi hellä (The night was beautiful and your voice so tender)
Everyday that I awake, I must be mindful
That everyday is all I have to call my own
Il est perdu dans la nuit, La lune, la lune
houd uw kanneke proper Dianneke, houd uw kanneke vaste (x2)
But the cardboard-filled windows and old men on the benches
Tell you now that the whole town is empty
#plik 
#clank
I wake up crying
You're making rain
But now I'm safe in the eye of the tornado
I can't replace the lies, that let a 1000 days go
I'd be crazy not to follow
Follow where you lead your eyes
