Detecting Information Relays in Deep Neural Networks

no code implementations3 Jan 2023 Arend Hintze, Christoph Adami

Deep learning of artificial neural networks (ANNs) is creating highly functional processes that are, unfortunately, nearly as hard to interpret as their biological counterparts.

EEG ERP

Emergence of functional information from multivariate correlations

no code implementations16 Sep 2021 Christoph Adami, Nitash C G

The information content of symbolic sequences (such as nucleic- or amino acid sequences, but also neuronal firings or strings of letters) can be calculated from an ensemble of such sequences, but because information cannot be assigned to single sequences, we cannot correlate information to other observables attached to the sequence.

Information Fragmentation, Encryption and Information Flow in Complex Biological Networks

1 code implementation28 May 2021 Clifford Bohm, Douglas Kirkpatrick, Victoria Cao, Christoph Adami

Assessing where and how information is stored in biological networks (such as neuronal and genetic networks) is a central task both in neuroscience and in molecular genetics, but most available tools focus on the network's structure as opposed to its function.

Can Transfer Entropy Infer Information Flow in Neuronal Circuits for Cognitive Processing?

no code implementations22 Jan 2019 Ali Tehrani-Saleh, Christoph Adami

To infer information flow in any network of agents, it is important first and foremost to establish causal temporal relations between the nodes.

Evolution leads to a diversity of motion-detection neuronal circuits

no code implementations7 Apr 2018 Ali Tehrani-Saleh, Thomas LaBar, Christoph Adami

A central goal of evolutionary biology is to explain the origins and distribution of diversity across life.

Motion Detection

The structure of evolved representations across different substrates for artificial intelligence

no code implementations5 Apr 2018 Arend Hintze, Douglas Kirkpatrick, Christoph Adami

Artificial neural networks (ANNs), while exceptionally useful for classification, are vulnerable to misdirection.

General Classification

The mind as a computational system

no code implementations1 Dec 2017 Christoph Adami

The present document is an excerpt of an essay that I wrote as part of my application material to graduate school in Computer Science (with a focus on Artificial Intelligence), in 1986.

Flies as Ship Captains? Digital Evolution Unravels Selective Pressures to Avoid Collision in Drosophila

no code implementations2 Mar 2016 Ali Tehrani-Saleh, Christoph Adami

Flies that walk in a covered planar arena on straight paths avoid colliding with each other, but which of the two flies stops is not random.

Collision Avoidance

Exploring the coevolution of predator and prey morphology and behavior

no code implementations29 Feb 2016 Randal S. Olson, Arend Hintze, Fred C. Dyer, Jason H. Moore, Christoph Adami

In this model, we observe a coevolutionary cycle between prey swarming behavior and the predator's visual system, where the predator and prey continually adapt their visual system and behavior, respectively, over evolutionary time in reaction to one another due to the well-known "predator confusion effect."

Information-theoretic considerations concerning the origin of life

no code implementations2 Sep 2014 Christoph Adami

Research investigating the origins of life usually focuses on exploring possible life-bearing chemistries in the pre-biotic Earth, or else on synthetic approaches.

Exploring the evolution of a trade-off between vigilance and foraging in group-living organisms

no code implementations8 Aug 2014 Randal S. Olson, Patrick B. Haley, Fred C. Dyer, Christoph Adami

Despite the fact that grouping behavior has been actively studied for over a century, the relative importance of the numerous proposed fitness benefits of grouping remain unclear.

More Bang For Your Buck: Quorum-Sensing Capabilities Improve the Efficacy of Suicidal Altruism

no code implementations2 Jun 2014 Anya Elaine Johnson, Eli Strauss, Rodney Pickett, Christoph Adami, Ian Dworkin, Heather J. Goldsby

Suicidal altruists could use quorum sensing to determine when exploding is most beneficial, but it is challenging to study the selective forces at work in microbes.

Leveraging Evolutionary Search to Discover Self-Adaptive and Self-Organizing Cellular Automata

no code implementations16 May 2014 David B. Knoester, Heather J. Goldsby, Christoph Adami

These results demonstrate that CA are a viable platform for studying the integration of self-adaptation and self-organization, and strengthen the case for using evolutionary algorithms as a component of SASO systems.

Risk aversion as an evolutionary adaptation

no code implementations23 Oct 2013 Arend Hintze, Randal S. Olson, Christoph Adami, Ralph Hertwig

We hypothesize that risk aversion in the equivalent mean payoff gamble is beneficial as an adaptation to living in small groups, and find that a preference for risk averse strategies only evolves in small populations of less than 1, 000 individuals, while agents exhibit no such strategy preference in larger populations.

Evolution of swarming behavior is shaped by how predators attack

7 code implementations22 Oct 2013 Randal S. Olson, David B. Knoester, Christoph Adami

Using an evolutionary model of a predator-prey system, we show that how predators attack is critical to the evolution of the selfish herd.

Predator confusion is sufficient to evolve swarming behavior

1 code implementation14 Sep 2012 Randal S. Olson, Arend Hintze, Fred C. Dyer, David B. Knoester, Christoph Adami

Using an evolutionary model of a predator-prey system, we show that predator confusion provides a sufficient selection pressure to evolve swarming behavior in prey.

The evolution of representation in simple cognitive networks

no code implementations25 Jun 2012 Lars Marstaller, Arend Hintze, Christoph Adami

Representations are internal models of the environment that can provide guidance to a behaving agent, even in the absence of sensory information.
