Adaptive Networks with Noisy Links

Ali H. Sayed

In biological systems, animals exhibit organized behavior that arises from localized interactions. The interaction is implemented through information exchange, either directly or indirectly. Adaptive networks, consisting of a collection of nodes with learn ...

How robot morphology and training order affect the learning of multiple behaviors

Joshua Evan Auerbach

Automatically synthesizing behaviors for robots with articulated bodies poses a number of challenges beyond those encountered when generating behaviors for simpler agents. One such challenge is how to optimize a controller that can orchestrate dynamic moti ...

We propose and validate a model for pedestrian walking behavior, based on discrete choice modeling. Two main types of behavior are identified: unconstrained and constrained. By unconstrained, we refer to behavior patterns which are independent from other i ...

Multiple Heterogeneous Ant Colonies with Information Exchange

Arash Arami, Bijan Rahimzadeh Rofoee

The method of multiple heterogeneous ant colonies with information exchange (MHACIE) is presented in this paper with emphasis on the speed of finding the optimal solution and the corresponding computational complexity. The proposed method which is inspired ...

Moving targets: Collective decisions and flexible choices in house-hunting ants

Roderich Gross

Many decisions involve a trade-off between commitment and flexibility. We show here that the collective decisions ants make over new nest sites are sometimes sufficiently flexible that the ants can change targets even after an emigration has begun. Our fin ...

A Discrete choice framework for acceleration and direction change behaviors in walking pedestrians

Michel Bierlaire, Gianluca Antonini

The walking process is interpreted as a sequence of decisions about where to put the next step. A dynamic and individual-based spatial discretization is used to represent the physical space. A behavioral framework for pedestrian dynamics based on discrete ...

Larger interregional synchrony is associated with greater behavioral success in a complex sensory integration task in humans

Friedhelm Christoph Hummel

Successful behavior depends on effective communication between distant brain regions. Moreover, disturbance of effective communication can cause neurological symptoms like apraxia, dyslexia or object agnosia. Interregional communication can be assessed by ...

A biologically inspired computational model of rodent repre-sentation?based (locale) navigation is presented. The model combines visual input in the form of realistic two dimensional grey-scale images and odometer signals to drive the firing of simulated p ...

To act or not to act. Neural correlates of executive control of learned motor behavior

Friedhelm Christoph Hummel

Successful behavior requires contextual modulation of learned "programs", that is, the retrieval or nonretrieval (inhibition) of behavioral elements depending on situative context. Here we report neural correlates of these elementary aspects of behavior as ...
