The Representation of Events in Multiagent Domains
نویسنده
چکیده
The purpose of this paper is to construct a mode! of actions ar,d events suited to reasoning about domains involving multiple agents or dynamic environments. A mode! is constructed that provides for simultaneous action, and the kind of facts necessary for reasoning about such actions are described. A model-bssed foul O~~Z~J~J~OIC.T is introduced to describe how actions affect the world. No frame axioms or syntactic frame rules are involved in the specification of any given action, thus allowing a proper mode!-theoretic semantics for the representation. Some serious deficiencies with existing approaches to reasoning about multiple agents are also identified. Finally, it is shown how the law of persistence, together with a notion of causality, makes it possible to retain a simp!e mode! of action while avoiding most of the difficulties associated with the frame problein.

Deep Unsupervised Domain Adaptation for Image Classification via Low Rank Representation Learning
Domain adaptation is a powerful technique given a wide amount of labeled data from similar attributes in different domains. In real-world applications, there is a huge number of data but almost more of them are unlabeled. It is effective in image classification where it is expensive and time-consuming to obtain adequate label data. We propose a novel method named DALRRL, which consists of deep ...
متن کاملImage Classification via Sparse Representation and Subspace Alignment
Image representation is a crucial problem in image processing where there exist many low-level representations of image, i.e., SIFT, HOG and so on. But there is a missing link across low-level and high-level semantic representations. In fact, traditional machine learning approaches, e.g., non-negative matrix factorization, sparse representation and principle component analysis are employed to d...
متن کاملChoosing appropriate theories for understanding hospital reporting of adverse drug events, a theoretical domains framework approach
Adverse drug events (ADEs) may cause serious injuries including death. Spontaneous reporting of ADEs plays a great role in detection and prevention of them, however, underreporting always exists. Although several interventions have been utilized to solve this problem, they are mainly based on experience and the rationale for choosing them has no theoretical base. The vast variety of behavioral ...
