abstract = {Exploring the Influence of Spontaneous Dynamics on
Reservoir Computing PerformanceInsights emerging from the
study of brain state-dependent neural dynamics have been
slow to influence the optimization and design of Machine
Learning (ML) and Artificial Intelligence (AI) algorithms.
Analysis of time signals recorded in neuroimaging studies
has demonstrated intricate dynamical patterns inherent to
conscious brain states, with complexity and proximity to
criticality associated with optimal cognitive performance.
While substantial investments are made to enhance the
performance of ML and AI by designing new hardware resources
like GPUs, supercomputers, quantum, and neuromorphic
machines, valuable lessons derived from studying the
state-dependence of the most efficient computer that we
know, the brain, can potentially be better incorporated into
ML workflows to ameliorate performance. ML research has
begun to achieve improved performance and enhanced learning
capabilities using brain-inspired classification algorithms,
e.g. programmed ”wake” or ”sleep” states. However,
to our knowledge, the implications of neuronal dynamics
observed specifically during conscious brain states has not
yet been thoroughly examined nor integrated into the design
or optimization of ML/AI algorithms. Reservoir Computing
(RC) is particularly well-suited for processing time series
data, due to its inherent capacity to capture temporal
dependencies and dynamics, as its echo state properties
amplify and propagate input information over time. To
explore the capacity of various dynamical regimes to
influence the performance of computations, we utilize RC to
solve various cognitive learning tasks implemented in
Neurogym (github.com/neurogym). In order to analyze time
series data from RC, we implement the Peturbational
Complexity Index (PCI) a clinical metric for discriminating
various levels of consciousness, and assess the fractal-like
dimensions making use of Detrended Fluctuation Analysis
(DFA). Furthermore, we analyze the dynamics of the reservoir
on exhibiting scale-invariance, sensitivity to
perturbations, and operating at a critical state, by
computing the Lyapunov exponents. These metrics contribute
to our understanding of how reservoir systems adapt and
organize information during the acquisition of new tasks. In
order to train the RC we make use of high performance
computing (HPC) resources and the L2L framework
(github.com/Meta-optimization/L2L), a Python implementation
of the well known ”Learning to Learn” ML paradigm. Using
RC enables the assessment of the complexity and criticality
of the signals, and the results can be applied in a
reversible manner to guide the network to maintain a
specific complexity and operate near criticality. Our
preliminary results indicate that, in analogy to enhanced
computational properties afforded to the brain during
conscious states, ML algorithms parameterized to support
near-critical and highly complex operational regimes
outperform the same algorithms parameterized with less
”conscious-like” dynamics. This work supports the
hypothesis regarding the utility of reverse engineering
neural principles derived from the study of brain
state-specific dynamics to optimize the computational
prowess of current ML/AI algorithms.* 16. Why would
attending ASSC benefit your career and the ASSC community?
Attending the Association for the Scientific Study of
Consciousness (ASSC) conference presents a valuable
opportunity to enrich both one's career and the ASSC
community. Professionally, participation in ASSC facilitates
networking with leading researchers and practitioners in the
field of consciousness studies, fostering collaborations and
opening avenues for future research endeavors. Engaging with
diverse perspectives and cutting-edge research presented at
the conference broadens one's knowledge and understanding of
consciousness science, contributing to professional growth
and development. Furthermore, active involvement in the ASSC
community through conference participation, presentations,
and discussions allows individuals to contribute their own
insights, research findings, and perspectives, thereby
enriching the collective knowledge base of the community. By
actively participating in ASSC, attendees not only benefit
personally and professionally but also contribute to the
advancement of consciousness research and the broader
scientific community.* 17. How would receipt of the travel
award facilitate your attending ASSC? How are you hoping to
use the travel award? Receiving the travel award would
significantly support my attendance at ASSC by alleviating
financial constraints associated with travel expenses and
childcare arrangements. The award would enable me to cover
the costs of transportation, accommodation, and childcare,
making it feasible for me to participate fully in the
conference activities. A very short justification on how
this work benefits or is linked to the ebrain-Health project
The tools used and advocated on this poster presentation are
the Peturbational Complexity Index (PCI) a measure used in
neuroscience to quantify the complexity (richness and
diversity) of brain responses to perturbations or stimuli,
and assess the long-range connections via fractal-like
dimensions making use of Detrended Fluctuation Analysis
(DFA). Furthermore, the dynamics are analyzed on the
exhibition of scale-invariance, sensitivity to
perturbations, and operating at a critical state, by
computing the Lyapunov exponents. The development and
utilization of these tools within the project are crucial
for enhancing the project's efficacy and achieving its
objectives. By enabling the analysis of simulated outputs
from The Virtual Brain, these tools provide valuable
insights into brain dynamics and their relation to health
conditions in the context of the Digital Twin. They
facilitate a more thorough examination of the relationships
within the simulated functional traces derived from the
output of various instances of the model. Additionally,
their integration within the workflow of Work Package 8
demonstrates the project's commitment to leveraging advanced
computational techniques to advance our understanding of
brain health. This strategic use of tools underscores the
project's broader goal of improving diagnostics and
treatment strategies for neurological disorders. Therefore,
their inclusion serves as a vital component in realizing the
project's overarching objectives. This work benefits
significantly from the discourse at a conference focused on
dynamics by offering valuable insights into the
effectiveness of various analytical methods as tools for
understanding complex dynamic systems. Moreover, it fosters
networking opportunities among researchers with shared
interests, laying the groundwork for future collaborations
and enhancing the project's impact within the scientific
community.},
