Clinical Assistant Diagnosis for Electronic Medical Record Based on Convolutional Neural Network
Automatically extracting useful information from electronic medical records
along with conducting disease diagnoses is a promising task for both clinical
decision support(CDS) and neural language processing(NLP). Most of the existing
systems are based on artificially constructed knowledge bases, and then
auxiliary diagnosis is done by rule matching. In this study, we present a
clinical intelligent decision approach based on Convolutional Neural
Networks(CNN), which can automatically extract high-level semantic information
of electronic medical records and then perform automatic diagnosis without
artificial construction of rules or knowledge bases. We use collected 18,590
copies of the real-world clinical electronic medical records to train and test
the proposed model. Experimental results show that the proposed model can
achieve 98.67\% accuracy and 96.02\% recall, which strongly supports that using
convolutional neural network to automatically learn high-level semantic
features of electronic medical records and then conduct assist diagnosis is
feasible and effective.Comment: 9 pages, 4 figures, Accepted by Scientific Report
Relative Well-Posedness of Constrained Systems with Applications to Variational Inequalities
The paper concerns foundations of sensitivity and stability analysis, being
primarily addressed constrained systems. We consider general models, which are
described by multifunctions between Banach spaces and concentrate on
characterizing their well-posedness properties that revolve around Lipschitz
stability and metric regularity relative to sets. The enhanced relative
well-posedness concepts allow us, in contrast to their standard counterparts,
encompassing various classes of constrained systems. Invoking tools of
variational analysis and generalized differentiation, we introduce new robust
notions of relative coderivatives. The novel machinery of variational analysis
leads us to establishing complete characterizations of the relative
well-posedness properties with further applications to stability of affine
variational inequalities. Most of the obtained results valid in general
infinite-dimensional settings are also new in finite dimensions.Comment: 25 page
