The Seven Deadly Sins of AI Predictions – MIT Technology Review

“Performance versus competence” and “Suitcase words”. Did I mention the slides to HORSE2017 have been posted: http://c4dm.eecs.qmul.ac.uk/horse2017/

Mistaken extrapolations, limited imagination, and other common mistakes that distract us from thinking more productively about the future.

HORSE2017 talks posted online

I have now posted the slides to all talks contributed at HORSE2017, and the videos where possible. The new A/V system in that room had a catastrophic error for the afternoon talks, so those are lost to time, unfortunately.

I wish to thank all presenters of the day, as well as the warm group of attendees. I also wish to thank my colleagues in the Machine Listening Lab for supporting the event.

A Derp Deep Learning Ditty

I decided to try something new: I will start a timer and then begin looking through and judging material generated by folk-rnn, recording my observations as I go, until I find something that is worth working with. How long will it take? How many transcriptions will I have to discard? How hard will it be to pick a good cherry? How much will I have to change the computer-generated material?

18h00
I open the folk-rnn v3 session book volume 4 of 4 and scroll randomly to transcription #8588:

M:4/4

Looks like we have ourselves a reel. It has an AABB form. There are no counting errors. I like the held over note in the first bar, and some of the sycopation. But what’s the c# doing in bar 3? It is natural in bars 2, 6-8. And bar 14 has a G#. Pulling to A major? Do I even have that note on my D/G diatonic accordion? (Yes, under one of those top-most accidental buttons.)

18h15

After futzing around for 15 minutes, I don’t think #8588 is salvageable. It feels like incoherent noodling. It’s a failure. Let’s go to the next one, transcription #8589:

M:4/4

The first 8 bars are in G, and the second are in Eminor. The transcription seems to be missing repeats though. Let’s remove the pickup and add repeats at the expected places, bars 8 and 16.

18h27

I have been futzing around with each section. The A melody is really boring. Can it be made more animated?

18:35

Wait a second. That boring three note figure in the A part can be in G or E minor. The alternation of G and Em sounds so cheesy. Like a Leonard Cohen song. Let’s use it. I make only a very minor change to bar 4, and add a simple chord progression. I play slowly to increase the cheese. The A part is finished.

19:00

The B part needs the most work I think. I keep the main idea of the melody, but change it’s ending in bar 10. That also changes bars 13-14. I compose bars 11-12 anew, and vary it in bars 15-16. Finally, I add a second ending to take us back to the A part. I add a chord progression, more complex than the A part.

19h30

We have arrived at a really sappy song (which I call “A Derp Deep Learning Ditty”) in an hour and a half, looking at only two folk-rnn v3 transcriptions. Let’s learn it, record it, and make a corny video to accompany (complete with a rap chorus).

Here it is without the rap:

Machine Learning and Human Behavior Postdoc positions

This looks like a fantastic opportunity!

Please apply by October 26, 2017

Emilia Gómez leads a novel research initiative inside the European Commission’s Joint Research Centre, on the topic of machine learning and human behaviour. Music will be an important aspect and use case of the project.

In this context, three postdoc positions in the area of machine learning and human behavior are open for appointment from January 1, 2018, at the Joint Research Centre (European Commission) in Seville, Spain. The fully funded positions are available for a period of three years.

The Joint Research Centre (JRC) is the European Commission’s science and knowledge service which employs scientists to carry out research in order to provide independent scientific advice and support to EU policy. The JRC Centre for Advanced Studies (JRC-CAS) was established to enhance the JRC’s capabilities to meet emerging challenges at the science-policy interface. JRC-CAS is now launching a three year interdisciplinary project to understand the potential impact of machine learning in human behavior and societal welfare. It will be carried out at JRC centre in Seville, Spain. There will be close collaboration with the Music Technology Group and the Department of Information and Communication Technologies of Universitat Pompeu Fabra  in Barcelona, Spain.

The project will (1) provide a scientific understanding of machine vs human intelligence; (2) analyze the influence of machine learning algorithms into human behavior (3) identify issues that may require a policy intervention. Music will be an important use case in the project. We are looking for postdoctoral researchers to join this challenging endeavour.

Particular areas of interests:

  • Fairness, accountability, transparency, explainability of machine learning methods.
  • Social, ethical and economic aspects of artificial intelligence.
  • Human-computer interaction and human-centered machine learning.
  • Digital and behavioural economy.
  • Application domains: music, arts, transport, social networks, health, energy.

We are looking for highly motivated, independent, and outstanding postdoc candidates with a strong background in machine learning and/or human behavior. An excellent research track record, ability to communicate research results and involvement in community initiatives is expected. Candidates should have EU/EEA citizenship.
The JRC offers an enriching multi-cultural and multi-lingual work environment with lifelong learning and professional development opportunities, and close links to top research organizations and international bodies around the world. Postdoctoral researchers receive a competitive salary and excellent working conditions, and will define their own research agenda inline with the project goals.

JRC-Seville is located in Cartuja 93 scientific and technological park. Seville is the fourth-largest city in Spain. With more than 30 centuries of history (gateway of America for two centuries, main actor in the first circumnavigation of the Earth),  three UNESCO World Heritage Sites, and privileged climate, it combines its historical and touristic character with a consolidated economic development and innovation potential.

You may obtain further information about the scientific aspects of the Postdoc positions from Dr. Emilia Gómez (project scientific leader: emilia.gomez@upf.edu) and at the following web pages http://recruitment.jrc.ec.europa.eu/?site=SVQ&type=AX&category=FGIV and https://ec.europa.eu/jrc/en/working-with-us/jobs.

folk-rnn (v2) tune #4542

As the world’s foremost interpreter of folk-rnn-generated tunes, I bring you another nice tune I have found. Tune #4542 can be found in the folk-rnn v2 Session Book Vol. 2 of 10. Here it is as output by the system:

4542_orig

I recently came across this tune when I randomly opened The Endless folk-rnn Traditional Music Session. It often happens that when I look at that page I find something interesting. Here is the synthesis of the tune above as I heard it:

The tune has an AABB structure with 8 measures for each part. folk-rnn chose a 3/4 meter, but most of the transcription is better expressed by 6/8. There is a minor miscounting error in bar 16, but everything else is counted ok.

I am drawn to this tune because of its lilt. It goes up and down and takes all kinds of twists and turns that make it hard for me to catch my breath. And once I do catch my breath the melody resolves. I really like the change in bar 11 from 2 groups of 3 quavers to 3 groups of 2 quavers. This creates a nice contrast.

Nonetheless, there are some things I change to make the tune better. I change the meter to 6/8. I drop the first measure of the B part down an octave, and add a second ending on the A part to help the transition. I change bar 10 to accelerate back to the upper register, and change bar 11 as a gradual descent. I finally add a harmonic progression that fits on my diato, and voilà!

And here I play the 6/8 piece with a 2/4 feel. Enjoy!
