Full-text available
We introduce new algebro-topological invariants of directed networks, based on the topological construction of the directed clique complex. The shape of the underlying directed graph is encoded in a way that can be studied mathematically to obtain network invariants such as the Euler characteristic and the Betti numbers. Two different cases illustr...
Article
We introduce an analysis method for electroen-cephalography (EEG) data, focused on Event-Related Potentials (ERPs). Our approach is unsupervised and makes use of a fuzzy clustering algorithm based on the possibilistic framework, and includes a data-driven noise and artifact rejection phase. Our contribution provides a general analysis tool, applica...

Full-text available
Gaze patterns during face perception have been shown to relate to psychiatric symptoms. Standard analysis of gaze behavior includes calculating fixations within arbitrarily predetermined areas of interest. In contrast to this approach, we present an objective, data-driven method for the analysis of gaze patterns and their relation to diagnostic tes...
Article
Objective To explore the possibilities of wearable multi-modal monitoring in epilepsy and to identify effective strategies for seizure-detection. Methods Thirty patients with suspected epilepsy admitted to video electroencephalography (EEG) monitoring were equipped with a wearable multi-modal setup capable of continuous recording of electrocardiog...

Many individuals with autism report that eye contact makes them stressed or uncomfortable. Besides expressing their right to respect for neurodiverse ways of nonverbal communication, some autistic individuals also express the wish to improve their capacity to tolerate eye contact. In the current study, five autistic adults completed a 21- to 28-day...

We investigate the effects of network topology on the dynamical activity of a hierarchically organized network of simulated spiking neurons. With a fixed basic two-by-two grid structure of processing modules each composed by almost 6000 leaky integrate-and-fire neurons and different connectivity schemes in between these modules, we study how the ac...

Conference Paper
Full-text available
A biologically-plausible simulation of a neuronal network is studied as its topology is shaped by its activity by means of an encoding of its connectivity structure as a directed clique complex. Specially defined invariants of this mathematical structure, including the information about synaptic strength, are introduced and show how the initial top...
Conference Paper
Full-text available
We propose a framework for an unsupervised analysis of electroencephalography (EEG) data based on possibilistic clustering, including a preliminary noise and artefact rejection. The proposed data flow identifies the existing similarities in a set of segments of EEG signals and their grouping according to relevant experimental conditions. The analys...

Chapter
Full-text available
The evolution of a simulated feed-forward neural network with recurrent excitatory connections and inhibitory forward connections is studied within the framework of algebraic topology. The dynamics includes pruning and strengthening of the excitatory connections. The invariants that we define are based on the connectivity structure of the underlyin...
Article
Full-text available
We define the notion of a formal connection for a smooth family of star products with fixed underlying symplectic structure. Such a formal connection allows one to relate star products at different points in the family. This generalizes the formal Hitchin connection introduced by the first author. We establish a necessary and sufficient condition t...

Due to the growing presence of ubiquitous data sources and the requirement for shorter and shorter response times, data streaming is steadily becoming the key technology to modern information processing, and this trend is bringing up new challenges. The task is to provide an *online* or *real-time* answer to the following questions, among others: - Segmentation: When does a concept start within a text, and where does it stop? Which objects are interesting in a video, and where are they located? When does a machine start to show a degradation process that will lead to a need for maintenance? Where does a spoken text start to show a certain mood? - Classification: What emotion does this text convey? When are we able to tell apart legitimate visitors from malicious bots by looking at http requests? Does a car in a video sequence violate street rules? Does a sudden street sound indicate that an accident has occurred? When feeling touched, should a robot back up to avoid a collision with a human, or is it simply being taught a new movement? - Forecasting: Will this car trajectory lead to an accident? What will be the traffic intensity on this road in five minutes from now?
