Machine learning and the arts: A creative continuum

Sketch a doodle of a drum or a saxophone to conjure a multi-instrumental composition. Look right into a webcam, communicate, and watch your mouth go bouncing throughout the display screen — the enter for a collection of charmingly clunky chain reactions.

That is what guests to the MIT Lewis Music Library encounter after they work together with two new digital installations, “Doodle Tunes” and “Sounds from the Mouth,” created by 2022-23 Center for Art and Technology (CAST) Visiting Artist Andreas Refsgaard in collaboration with Music Know-how and Digital Media Librarian Caleb Corridor. The residency was initiated by Avery Boddie, Lewis Music Library division head, who acknowledged Refsgaard’s aptitude for revealing the playfulness of rising applied sciences. The intricacies of coding and machine studying can appear formidable to newcomers, however Refsgaard’s apply as a inventive coder, interplay designer, and educator seeks to open the sphere to all. Encompassing workshops, an artist speak, class visits, and an exhibition, the residency was infused along with his distinctive humorousness — a mix of full of life eccentricity and easygoing relatability.

Machine Studying and the Arts with MIT CAST Visiting Artist Andreas Refsgaard

Studying by means of laughter

Refsgaard, who relies in Copenhagen, is a real maverick of machine studying. “I’m within the methods we will categorical ourselves by means of code,” he explains. “I prefer to make unconventional connections between inputs and outputs, with the pc serving as a translator — a instrument may help you play music along with your eyes, or it’d generate a love poem from a photograph of a burrito.” Refsgaard’s explicit spin on innovation isn’t about straight fixing issues or launching world-changing startups. As a substitute, he merely seeks to “poke at what will be accomplished,” offering accessible open-source templates to immediate new inventive concepts and purposes.

Programmed by Refsgaard and that includes a customized set of sounds created by Corridor, “Doodle Tunes” and “Sounds from the Mouth” show how unique compositions will be generated by means of a mixture of spontaneous human gestures and algorithmically produced outputs. In “Doodle Tunes,” a machine studying algorithm is skilled on a dataset of drawings of various devices: a piano, drums, bass guitar, or saxophone. When the person sketches considered one of these pictures on a touchscreen, a sound is generated; the extra devices you add, the extra complicated the composition. “Sounds from the Mouth” works by means of facial monitoring and self-capturing pictures. When the participant faces a webcam and opens their mouth, an autonomous snapshot is created which bounces off the notes of a piano.

Libraries, limitless

Saxophone squeals and digital drum beats aren’t the one sounds issuing from the areas the place the tasks are put in. “My workplace is shut by,” says Corridor. “So after I all of a sudden hear laughter, I do know precisely what’s up.” This new sonic dimension of the Lewis Music Library suits with the ethos of the surroundings as a complete — designed as a campus hub for audio experimentation, the library was by no means meant to be wholly silent. Refsgaard’s residency exemplifies a brand new emphasis on progressive programming spearheaded by Boddie, because the technique of the library shifts towards a concentrate on digital collections and music know-how.

“Along with serving as an area for quiet examine and entry to bodily assets, we wish the library to be a spot the place customers congregate, collaborate, and discover collectively,” says Boddie. “This residency was very profitable in that regard. By means of the workshops, we have been capable of join people from throughout the MIT neighborhood and their distinctive disciplines. We had folks from the Sloan Faculty of Administration, from the Schwarzman Faculty of Computing, from Music and Theater Arts, all working collectively, getting messy, creating instruments that typically labored … and typically didn’t.”

Error and serendipity

The combination of error is a key high quality of Refgaard’s work. Occasional glitches are a part of the artistry, they usually additionally serve to softly undermine the hype round AI; an algorithm is simply pretty much as good as its dataset, and that set is inflected by human biases and oversights. Throughout a public artist speak, “Machine Studying and the Arts,” viewers members have been initiated into Refsgaard’s offbeat inventive paradigm, offered with tasks corresponding to (an internet bookstore for AI-produced sci-fi novels), Is it FUNKY? (an try to tell apart between “enjoyable” and “boring” pictures), and Eye Conductor (an interface to play music by way of eye actions and facial gestures). Glitches within the exhibit installations have been frankly admitted (it’s true that “Doodle Tunes” often errors a drawing of a saxophone for a squirrel), and Refsgaard inspired viewers members to recommend potential enhancements.

This open-minded angle set the tone of the workshops “Artwork, Algorithms and Synthetic Intelligence” and “Machine Studying for Interplay Designers,” meant to be appropriate for newcomers in addition to curious consultants. Refsgaard’s visits to music know-how lessons explored the ways in which human creativity might be amplified by machine studying, and how one can navigate the sliding scale between inventive intention and sudden outcomes. “As I see it, success is when contributors interact with the fabric and provide you with new concepts. Step one of studying is to grasp what’s being taught — the following is to use that understanding in ways in which the instructor couldn’t have foreseen.”

Uncertainty and alternative

Refsgaard’s work exemplifies a few of the core values and questions central to the evolution of MIT Libraries — problems with digitization, computation, and open entry. By selecting to make his lighthearted demos freely accessible, he renounces possession of his concepts; a machine studying mannequin may function a studying gadget for a pupil, and it’d equally be monetized by a company. For Refsgaard, play is a manner of partaking with the moral implications of rising applied sciences, and Corridor discovered himself grappling with these questions within the course of of making the sounds for the 2 installations. “If I wrote the sound samples, however another person organized them as a composition, then who owns the music? Or does the AI personal the music? It’s an extremely attention-grabbing time to be working in music know-how; we’re coming into into unknown territory.”

For Refsgaard, uncertainty is the key sauce of his algorithmic artistry. “I prefer to make issues the place I’m stunned by the top outcome,” he says. “I’m in search of that candy spot between one thing acquainted and one thing sudden.” As he explains, an excessive amount of shock merely quantities to noise, however there’s one thing joyful within the risk {that a} machine may mistake a saxophone for a squirrel. The duty of a inventive coder is to repeatedly tune the connection between human and machine capabilities — to search out and comply with the music.
