a Multi-Perspective Approach to Anomaly Detection for Self -Aware Embodied Agents

Abstract: This paper focuses on multi-sensor anomaly detection for moving cognitive agents using both external and private first-person visual observations. Both observation types are used to characterize agents motion in a given environment. The proposed method generates locally uniform motion models by dividing a Gaussian process that approximates agents displacements on the scene and provides a Shared Level (SL) self-awareness based on Environment Centered (EC) models. Such models are then used to train in a semi-uns… Show more

“…In a lot of existing approaches, this is done offline by trying to take into account a large amount of possible situations. These systems have impressive results in particular environments and situations; nonetheless, they can be totally disoriented in other situations [3,4,10]. Machine learning is one of the promising research areas that try to solve this kind of problems.…”

“…Recent developments in signal processing and machine learning techniques can be useful to design autonomous systems equipped with a self-awareness module to make it possible to compare how much the current realization is similar to a previous experience of the same type while a given task is executed. The capability of predicting task evolution in normal conditions (i.e., when the task follows the rules learned in the previous experience) and jointly detecting abnormal situations that can rise based on such self-awareness is an important task that allows autonomous systems to increase their situational awareness and the effectiveness of the decision making submodules [2], [3]. Models of different self-awareness layers can be integrated in order to buildup a structured and multi-modal self-aware behavior for an agent.…”

“…In [3] a self-awareness model was introduced that consists of two layers: Shared Level (SL) and Private Layer (PL). The analysis of observed moving agents for learning the models of normal/abnormal dynamics in a given scene from an external viewpoint, represents an emerging research field [4][5][6][7][8][9][10][11][12].…”

“…Self-awareness models make it possible for an agent to evaluate whether faced situations at a given time correspond to previous experiences. Self-aware computational models have been studied and several architectures have been introduced [1,2,3,4]. Such models have to provide a framework where autonomous decisions and/or teleoperation by a human can be integrated as a capability of the device itself to dynamically evaluate the contextual situation [3].…”
