Knowledge-Based Spatiotemporal Abstraction
We present a case study of reusing the same problemsolving method for the related tasks of temporal abstraction and linear-space abstraction. The method, known as knowledge-based temporal abstraction, abstracts high-level concepts from time-stamped raw data, and was evaluated primarily in clinical domains. We applied this method to the domain of traffic control, in which the monitoring task req...
متن کاملKnowledge-based temporal abstraction in clinical domains
We have defined a knowledge-based framework for the creation of abstract, interval-based concepts from time-stamped clinical data, the knowledge-based temporal-abstraction (KBTA) method. The KBTA method decomposes its task into five subtasks; for each subtask we propose a formal solving mechanism. Our framework emphasizes explicit representation of knowledge required for abstraction of time-ori...
متن کاملA Framework for Knowledge-Based Temporal Abstraction
A new domain-independent knowledge-based inference structure is presented, specific to the task of abstracting higher-level concepts from time-stamped data. The framework includes a model of time, parameters, events, and contexts. A formal specification of a domainÕs temporal-abstraction knowledge supports acquisition, maintenance, reuse, and sharing of that knowledge. The knowledge-based tempo...
متن کاملKnowledge-Based Linear Programming
We introduce a class of linear programs with constraints in the form of implications. Such linear programs arise in support vector machine classification, where in addition to explicit datasets to be classified, prior knowledge such as expert’s experience in the form of logical implications, are imposed on the classifier. The overall problem can be viewed either as a semi-infinite linear progra...
متن کاملKnowledge-Based Temporal Abstraction in Clinical-Management Tasks
We describe a general method for abstracting higherlevel, interval-based concepts from time-stamped clinical data, the knowledge-based temporal-abstraction [KBTA] method. We focus on the knowledge representation, knowledge acquisition and knowledge reuse and sharing aspects of the KBTA method. We describe five mechanisms which solve the five tasks composing the KBTA method, and four types of kn...
