From February 7 through March 17, 2018, Pilevneli Gallery presented Refik Anadol’s latest project on the materiality of remembering. Melting Memories offered new insights into the representational possibilities emerging from the intersection of advanced technology and contemporary art. By showcasing several interdisciplinary projects that translate the elusive process of memory retrieval into data collections, the exhibition immersed visitors in Anadol’s creative vision of “recollection.”

“Science states meanings; art expresses them,” writes American philosopher John Dewey and draws a curious distinction between what he sees as the principal modes of communication in both disciplines. In Melting Memories, Refik Anadol’s expressive statements provide the viewer with revealing and contemplative artworks that will generate responses to Dewey’s thesis.

Comprising data paintings, augmented data sculptures and light projections, the project as a whole debuts new advances in technology that enable visitors to experience aesthetic interpretations of motor movements inside a human brain. Each work grows out of the artist’s impressive experiments with the advanced technology tools provided by the Neuroscape Laboratory at the University of California, San Francisco. Neuroscape is a neuroscience center focusing on technology creation and scientific research on brain function of both healthy and impaired individuals. Anadol gathers data on the neural mechanisms of cognitive control from an EEG (electroencephalogram) that measures changes in brain wave activity and provides evidence of how the brain functions over time. These data sets constitute the building blocks for the unique algorithms that the artist needs for the multi-dimensional visual structures on display.

Anadol’s installations do not only address a productive espousal of cutting-edge technology and art but also a strong preoccupation with the study of human memory from Ancient Egyptians to Blade Runner 2049. The exhibition’s title, Melting Memories, refers to the artist’s experience with unexpected interconnections among seminal philosophical works, academic inquiries and artworks that take memory as their principal themes. The title further draws attention to the melting of neuroscience and technology into these centuries-long philosophical debates, questioning the emergence of a new space where artificial intelligence is not in conflict with individuality and intimacy.

PROCESS
The data collection process utilized a 32-channel Enobio and standard protocol configuration. Participants were instructed to focus on specific long-term memories during the recording process. A control recording was also conducted to identify artifacts to later filter with adaptive notch filtering and limiting the frequency range.

For analysis we focused on beta (13-17Hz) and theta (3-7Hz) channels, isolating activation points corresponding to short term and long-term (specifically episodic) memory. Our selections were the Fp1, Fp2, F7, F8, P3, P4, C3, C4, T7, T8, O1, and O2 nodes, which were also used to drive noise parameters within the real-time simulation. For scaling we applied Higuchi’s fractal dimension algorithm and used FFT for a moving average. Recurrent neural nets (via EEGLearn) we used on the recording sessions to generate spectral outputs, which were then utilized as height maps for the visual representation pipeline.

VVVV Workflow
Transposing EEG data in to procedural noise forms was a really engaging challenge, both technically and conceptually. In the input data and our mapped representation you can find recurrence and rhythm but also hints of higher dimensional structures. We wanted to do this efficiently and in real time and so working on Melting Memories dovetailed nicely with putting the last touches on FieldTrip, an (at the time pre-release) open source GPU library for HLSL/vvvv. It allowed us to use a composite design pattern to very quickly iterate while producing the aesthetic structures used in the project. This approach enabled us to really explore some deeper procedural functions whilst keeping a completely modular graphics pipeline. This modularity makes it easy and clean to expand on the project’s abstracted content in really interesting ways, such as further integration of machine learning on the source data, evolving rendering techniques and the creation of sculpted physical artifacts.
