Healthcare has and continues to be an integral component in people's lives, especially for the rising elderly population. One such healthcare program that provides for the needs of the elderly is Medicare. It is important that any such program be affordable but, unfortunately, this is not always the case. Out of the many possible factors for the rising cost of healthcare, fraud is a major contributor,...
Elastic systems utilize both human and machine working units to accomplish tasks that are eligible for crowdsourcing. The quality in the results of work completed by either type of computing unit is tantamount on the characteristics they bear. In this paper we draw parallels from our previous work into looking at the suitability of working units in completing viable tasks in crowdsourcing. We seek...
Machine learning models deployed in real world applications, operate in a dynamic environment where the datadistribution can change constantly. These changes, calledconcept drifts, cause the performance of the learned modelto degrade over time. As such it is essential to detect andadapt to changes in the data, for the model to be of any realuse. While, model adaptation requires labeled data (for retraining),...
One of the deficiencies in Z tools is that there is limited support for model checking Z specifications. It is found that building a model checker directly for a Z specification will take considerable effort and time due to an abstraction of the language. Translating a specification input on the Z language into a specification with language that an existing model checker tool accepts is an alternative...
In the last years, the large availability of data and schema models formalized through different languages has demanded effective and efficient methodologies to reuse such models. One of the most challenging problem consists in integrating different models in a global conceptualization of a specific knowledge or application domain. This is a hard task to accomplish due to ambiguities, inconsistencies...
