Deep XOR

February 26th, 2017 No comments

Since deep learning is so hot nowadays, I put together a notebook with a little exercise I undertook to have a better understanding of how neural networks work: modeling a XOR gate using a feedforward network with a single hidden layer. I named it Deep XOR.

The derivation of all necessary equations and their implementation in numpy are included. Hopefully it may help other practitioners too.

2016

December 31st, 2016 No comments

Years are starting to pass by at high speeds. Not light speed, not hyperloop speed, but maybe high-speed-trains speed. My first year in Oakland is waiving goodbye, and while crazy shit has happened in the world this year, I certainly can’t complain of who and what is around me. I feel extremely privileged and thankful for having had the opportunity to be on this fast-paced ride that only stops once. Let’s keep moving.

List of things that gave meaning to this little (highly probably simulated) life:

  • Cover of Time Travelers by Riverside
  • Performance with Los Pandejos at the Pandora Music Analyst Fest
  • I join Arkaen, a new metal band from Concord that will save the world
  • My music structure analysis algorithms make it to the new Harmonix Music VR game by the developers of Rock Band
  • First time skiing in Tahoe like a real white male in his 30s who works in tech
  • Dagstuhl Seminar in Germany
  • Nathalie studies in Oxford and I visit her and it is more magical than Hogwarts
  • Trip to Barcelona to do some tourism
  • La Bossa d’Urina Aznar Spring World Tour 2016
  • Organized the BISH Bash at Pandora (Los Pandejos also play there)
  • Mom visits the Bay Area!

  • Freak Kitchen features the cover I made a few years ago in their page
  • Pliny The Elder becomes my favorite beer
  • Jordan Rudess invites me to his backstage room to talk and play with some of his newest toys
  • We record our first demo with Arkaen
  • James Hetfield suddenly shows up in a Corrosion of Conformity show and reminds me how awesome the Bay Area is
  • Cover of England by The National (for Natis)
  • One of my dreams come true: cover of The Beginning and The End by Anathema WITH JORDAN RUDESS
  • Cover of Anna Molly by Incubus with some of the titans of Sargon
  • Cover of The Last Goodbye (The Hobbit) with the titans Andy Feehan et al.
  • ICML in NYC: organized the Music Discovery Workshop
  • Cover of Mother by Pink Floyd with the titan Alek Darson
  • I buy a second-hand Mesa/Boogie Mark-III
  • Nat comes back from Oxford and is ready to take over Berkeley
  • Another Winter in Lima
  • First time surfing (in Miraflores!)
  • ISMIR in NYC: presented this paper and organized the JAM session.
  • Cover of the Dragon Ball intro with The Only Deer Alive
  • First Arkaen show
  • Sister visits me in Oakland
  • I give a long talk at the Stanford Biostat Seminar about deep learning and music
  • Los Pandejos Show @ Pandora Performs (The Fillmore)
  • Cover of The Pretender by Foo Fighters with the titans Alek Darson et al.
  • Post-Trump election anti-depression concert by Los Pandejos
  • Thanksgiving in Miami with Natis’ family, sister, mom, and Eliseu (first intra family encounters are a success!)
  • I give a talk at the Seminar of Music Knowledge Extraction using Machine Learning at UPF, Barcelona
  • NIPS in Barcelona
  • Another dream comes true this year: Venga Monjas Videoclip for La Bossa d’Urina (EPIC)
  • La Bossa d’Urina La Vida Secreta d’en Follet Tortuga Winter World Tour 2016 (most extensive World Tour we’ve made so far)
  • Natis is among the top two students in her Torts class, because she is the titanest (congrats!)
  • Christmas and New Years Eve in Barcelona

Happy 2017 titanics!

New Official Video for Es Tarde by La Bossa d’Urina

December 24th, 2016 No comments

The titans of Venga Monjas, our long-term idols, made the new video of La Bossa d’Urina and it is the most perfect video on Earth and probably all our Milky Way. Here you have it:

La Bossa d’Urina’s Upcoming World Tour

November 30th, 2016 No comments

We did it. We managed to squeeze 7 shows in 21 days all around the world. More specifically, eastern Catalonia.

This time the tour is named after our lifetime hero: Master Roshi (aka Follet Tortuga in Catalan), who wrote the Pillars Of The Earth, saved the world several times, and I’m sure he will save it again during the Trumpocalypse.

Here you have the dates with the locations, see you there, brave titans:

Dragon Ball – Bola de Drac – Cover with The Only Deer Alive

September 30th, 2016 No comments

Here it is titanics. The song we grew up with. The song that made us humans. The song that made us wanna search for Dragon Balls instead of fucking Pokémons. Here it is for you, titans, in all it’s glory (in Japanese, Polish, or Catalan).

Guitars, Bass, Drums, Keyboards, Mixing, and Everything Else: The Only Deer Alive. WHAT A TITAN, RIGHT?

Teaming up with Alek Darson for Pink Floyd cover

July 15th, 2016 No comments

Oh, titanics. The day has come I teamed up with one of the greatest (if not The Greatest) guitarist I’ve ever performed with: Alek Darson. Given the interesting times we live in, we found it appropriate to cover this magnificent classic by Pink Floyd. Hope you enjoy it as much as we did making it!

Also: more covers with Alek to come. YES. Alright!

Anna Molly – Cover with 3/4 of Sargon

June 24th, 2016 No comments

The legend was true: Sargon (or rather, 3/4 of it) is back! Now that the EU got smaller, we decided to reunite for this silly cover of Anna Molly, by Incubus. If you look carefully, you will suddenly see some younger versions of ourselves. They’re not our children, it’s just high quality photoshop skills. Enjoy!

Anathema cover with Jordan Rudess!

May 15th, 2016 No comments

When The Wizard Titan Jordan Rudess saw my Anathema cover decided that he wanted to give it some GeoShred love. So we worked together to create this little piece of video that I absolutely love. I hope you enjoy it Titans!

Wizard power! GeoShred power! Dream Theater powerrrrr

The Beginning And The End – Anathema Cover

May 13th, 2016 No comments

Alright: another cover released to make the world a better place. Thank you Anathema for making my life much better since… I don’t know, probably since early 2000s (that’s roughly half the time I’ve been alive).

Enjoy titanics!

England – Cover by The National

April 25th, 2016 No comments

I love this song. So much. I tried to cover it, but of course this doesn’t compare to the original in any possible sense. Maybe in the title. And the chords (almost). Regardless, this is for Natishrimpers The Llama, who lives in that beautiful country surrounded by hobbits and muggles. Miss you guapa.
