Social roles in hierarchical models for human activity recognition
We present a hierarchical model for human activity recognition in entire multi-person scenes. Our model describes human behaviour at multiple levels of detail, ranging from low-le...

Delta-Dual Hierarchical Dirichlet Processes: A pragmatic abnormal behaviour detector
In the security domain a key problem is identifying rare behaviours of interest. Training examples for these behaviours may or may not exist, and if they do exist there will be fe...

Behaviour Recognition using the Event Calculus
We present a system for recognising human behaviour given a symbolic representation of surveillance videos. The input of our system is a set of timestamped short-term behaviours, t...

Permissive strategies: from parity games to safety games
It is proposed to compare strategies in a parity game by comparing the sets of behaviours they allow. For such a game, there may be no winning strategy that encompasses all the be...

Weighted automata with discounting
: We investigate weighted automata with discounting and their behaviours over semirings and finitely generated graded monoids. We characterize the discounted behaviours of weighted...

On the Observable Behaviour of Composite Components
The crucial strength of the component paradigm lies in the possibility to encapsulate behaviours. In this work, we focus on the observable behaviour of composite components which ...

Simulating a computational grid with networked animat agents
Computational grids are now widespread, but their large-scale behaviour is still poorly understood. We report on some calculations of loading, scaling and utilisation behaviours o...

Symbolic Model Based Testing for Component Oriented Systems
In a component oriented approach, components are designed, developed and validated in order to be widely used. However one cannot always foresee which specific uses will be made o...

Towards a Monitoring Framework for Agent-Based Contract Systems
The behaviours of autonomous agents may deviate from those deemed to be for the good of the societal systems of which they are a part. Norms have therefore been proposed as a means...

Detecting Execution Failures Using Learned Action Models
reason with abstracted models of the behaviours they use to construct plans. When plans are turned into the instructions that drive an executive, the real behaviours interacting w...
