This paper presents our solution for the i2b2 sentiment classification challenge. Our hybrid system consists of machine learning and rule-based classifiers. For the machine learning classifier, we investigate a variety of lexical, syntactic and knowledge-based features, and show how much these features contribute to the performance of the classifier through experiments. For the rule-based class...

This paper deals with recognition of isolated words by hybrid approach. The brief description of the principles of hybrid recognition is introduced, the recognition phases and feature optimisations are introduced. The report is concluded by practical part with performance results.

Maltese is a morphologically rich language with a hybrid morphological system which features both concatenative and non-concatenative processes. This paper analyses the impact of this hybridity on the performance of machine learning techniques for morphological labelling and clustering. In particular, we analyse a dataset of morphologically related word clusters to evaluate the difference in re...

We re-examine the basic hybrid control set-up of a continuous plant in a closed feedback loop with a finite state control automaton and an interface consisting of an A/D map and a D/A map. We address the question of how dynamic specifications can be formulated independently of a particular A/D map, and of the effect of refining an A/D map. The main contribution of this paper is that it extends ...

Big data technology has gained attention in all fields, particularly with regard to research and financial institutions. This changed the world tremendously. Researchers scientists are currently working on its applicability different domains such as health care, medicine, stock market, among others. The being generated at an unexpected pace from multiple sources like social media, care contexts...

We have developed a hybrid system safety prover, implemented in Coq using the abstraction method introduced by [2]. The development includes: a formalisation of the structure of hybrid systems; a framework for the construction of an abstract system (consisting of decidable “over-estimators” of abstract transitions and initiality) faithfully representing a concrete hybrid system; a translation o...
