This paper introduces our several preliminary approaches toward understanding temporal soundspace partitioning in bird communities as a self-organizing phenomenon based on behavioral plasticity. First, we describe this phenomenon from our recordings, and show there are asymmetric relationships and the diversity in the temporal avoidance behaviors among the species, using transfer entropy analys...

Many algorithms for temporal video partitioning rely on the analysis of uncompressed video features. Since the information relevant to the partitioning process can be extracted directly from the MPEG compressed stream, higher efficiency can be achieved utilising information from the MPEG compressed domain. This paper introduces a real time algorithm for scene change detection that analyses the ...

Multivoxel pattern analysis of functional magnetic resonance imaging (fMRI) data is continuing to increase in popularity. Like all fMRI analyses, these analyses require extensive data processing and methodological choices, but the impact of these decisions on the final results is not always known. This study explores the impact of four methodological choices on analysis outcomes and introduces ...

We present an automated temporal partitioning applied on the data-path part of an algorithm for the reconfigurable embedded system design. This temporal partitioning, included in a design space exploration methodology, uses trade-offs in time constraint, design size and FPGA device parameters (circuit speed, reconfiguration time). The originality of this partitioning is that it minimize the num...

This paper demonstrates the advantages of using a hybrid reinforcement–modular neural network architecture for non-linear control. Specifically, the method of ACTION-CRITIC reinforcement learning, modular neural networks, competitive learning and stochastic updating are combined. This provides an architecture able to both support temporal difference learning and probabilistic partitioning of th...

The recent introduction of partially-reconfigurable-field-programmable gate arrays (PRFPGAs) has led to the need for new algorithms suited for use with these devices. Although algorithms developed for use with field-programmable gate arrays can be applied to PRFPGAs, these algorithms do not take advantage of features available in these new devices. This paper examines the applicability of PRFPG...

We present a control strategy for an autonomous vehicle that is required to satisfy a rich mission specification over service requests occurring at the regions of a partitioned environment. The overall mission specification consists of a temporal logic statement over a set of static, a priori known requests, and a servicing priority order over a set of dynamic requests that can be sensed locall...

Introduction Qualitative spatial reasoning is a valid support for inferring relationships in geographical spaces. In particular, qualitative inferences are cognitively more expressive than quantitative ones, and support reasoning mechanisms in the absence of complete spatial knowledge (Cohn 1997). In geographical space, reasoning on spatial entities is supported by representations that mainly i...

Joins are the most expensive and performance-critical operations in relational database systems. In this thesis, we investigate processing techniques for joins that are based on a temporal intersection condition. Intuitively, such joins are used whenever one wants to match data from two or more relations that is valid at the same time. This work is divided into two parts. First, we analyse tech...

Reasoning about the location of regions in 2-dimensional space is necessarily based on nite approximations to such regions. These nite approximations are often derived by describing how a region (the gure) relates to a frame of reference (the ground). The frame of reference generally consists of regions, or cells, forming a partition of the space under consideration. This paper presents a new a...
