Fuzzy Methods in Medical Research and Patient Care – in Memoriam Lotfi A. Zadeh

Klaus-Peter Adlassnig

Medical University of Vienna, Austria

Abstract To digitize medical knowledge, one needs to discern, formalize, and represent medical entities and their inter-relationships. Medical entities such as fever or hypoxemia are characterized by linguistic uncertainty. The unsharpness of boundaries in these linguistic terms is modeled by fuzzy sets. Relationships between medical entities are characterized by propositional uncertainty, which is due to the incompleteness of medical conclusions. Propositional uncertainty is modeled by truth values between zero and one. When measurements map into fuzzy sets, the results are combined with truth values of medical propositions, and logical conclusions are drawn. One method is the compositional rule of fuzzy inference, in several forms and successively.  Fuzzy automata offer an interesting way to calculate “fuzzy states” of patients in a clear and clinically comprehensible manner. These states represent physiological or pathophysiological states—based on measured patient data—and allow for grades of “health” or “illness”. States are characterized by linguistic terms and state transitions are described by linguistic instructions. If medical devices need to be controlled, but control rules are heuristic, then fuzzy control yields powerful solutions. It might be advisable to follow an open-loop control cycle, with a human physician carefully examining the control output and performing the actual control.  Arden Syntax is a medical knowledge representation and processing language, issued and supported by Health Level Seven (HL7) International, a standard developing organization for health IT standards. In 2013, the Health Level Seven Arden Syntax for Medical Logic Systems, version 2.9, including fuzzy methodologies, was issued by HL7 and approved by the American National Standards Institute.

Multiagent Smart Communication based on CI Technology


Beijing Institute of Technology, China

Abstract: The presenters’ group has been studying on humans-robots interaction based on Computational Intelligence in the frame work of multiagent smart society, where a concept of Fuzzy Atmosfield (FA) is proposed to express the atmosphere in humans-robots communication. The FA is characterized by a 3D fuzzy cubic space with “friendly-hostile”, “lively-calm”, and “casual-formal” based on a cognitive science experiment and PCA. To understand easily such movement of the atmosphere, a graphical representation method is also proposed. To illustrate the FA and its visualization method, a demonstration scenario “enjoying home party by five eye robots and four humans” is introduced/demonstrated. Then, a visualization method of users’ emotion information is proposed for long distance interaction such as telecommuting and distance learning, where 3D emotion vectors in Affinity Pleasure-Arousal space are illustrated by using shape-brightness-size (SBS) figure. It gives users easily understandable emotional profile information, and provides administrator strategic suggestion to improve the interaction between the users and the system. In the matching experiment between 7 basic emotions and 7 SBS figures for 8 subjects, 83.93% matching is achieved, and the administrator finds contents improvement hint in the questionnaire of emotions for 5 reading-text-tasks by 8 subjects. It is planning to be implemented in a language learning application to provide a more comfortable learning experience by contents selection based on user’s emotion.

Keynote Speech 5:

Artficial Intelligence and Clinical Decision Support

Klaus-Peter Adlassnig

Medical University of Vienna, Austria

Abstract: Health information technology (IT) systems gather, store, transfer, and display the medical data of patients in a computerized and structured form. Examples are patient history data, signs collected during the physical examination, laboratory test results, and findings from clinical investigations (imaging, endoscopy, histology, genetic, and others). These describe the present or previous states of a patient’s health (or illness).

To draw conclusions about patient care based on these data in a partly or fully automated manner, one needs what is generally known as medical knowledge. One also needs this medical knowledge in a computerized and structured form. How to interpret a patient’s symptoms or laboratory data, how to administer medication but avoid adverse drug events, how to detect any worsening of the disease or identify chronic disease, and how to monitor and curb healthcare-associated infections at the medical institution—all of these are examples of smaller or larger cutouts of the large body of medical knowledge.

Combining digitized patient medical data with digitized medical knowledge to generate diagnostic, therapeutic, prognostic, or patient management suggestions is currently referred to as clinical decision support. In former times, such methods or systems were known as computer-assisted diagnosis and therapy, medical expert systems, or artificial intelligence in medicine. Now, the latter also includes machine learning in various forms.

Artificial Intelligence in Infection Control – Healthcare Institutions Need Intelligent Information and Communication Technologies for Surveillance and Benchmarking

Walter Koller, MD

Medical University of Vienna, Austria

Abstract:   Modern healthcare and medicine depend on the implementation of best practice, which includes surveillance of, and benchmarking with, predefined quality indicators. Given the automated analysis of microbiological findings and automated surveillance of healthcare-associated infections (HAIs), we put forward arguments in favor of the increasing use of intelligent information and communication technologies for the assessment and surveillance of infection. With MOMO, a modern microbiology analytics software, as well as with MONI, a fully automated detection and monitoring system for HAIs, we registered a much greater precision of analytics and surveillance. The time taken by these systems was much less than that needed for conventional surveillance. We registered the need for timely amendments and adaptations concerning new input categories or new reporting outputs as desired by clinicians, administrators, and health authorities. Intelligent information and communication technologies are thus becoming indispensable in the construction of affordable “safety nets” for quality assurance and benchmarking, based on fully automated and intelligent data and knowledge management. These, in turn, constitute the backbone of high-level healthcare, patient safety, and error prevention.

Visualizing and Understanding Neural Networks 

Anh Nguyen

Auburn University, USA

Abstract: Understanding a deep learning model’s inner-workings and decisions is increasingly important, especially for life-critical applications e.g. in medical diagnosis or criminal justice. In this talk, I will discuss our recent findings of some interesting failures of state-of-the-art image classifiers. For example, simply randomly rotating and randomly placing a familiar, training-set object in front of the camera is sufficient to bring the classification accuracy from 77.5% down to 3%. Such notorious brittleness of neural networks, therefore, begs for better explanations of why a model makes a decision. In this quest, I will share some recent work showing that interpretability methods are unreliable, being sensitive to hyperparameters and how harnessing generative models to synthesize counterfactual intervention samples can improve the robustness and accuracy of the attribution methods.

Biography: Anh completed his Ph.D. in 2017 at the University of Wyoming, working with Jeff Clune and Jason Yosinski. He is an Assistant Professor in Computer Science at the Auburn University, USA.

Keynote Speech 9: “Meta heuristic approaches to imputing for Imbalanced Data Set” 

Junzo Watada

Universiti Teknologi PETRONAS, Seri-Iskandar, Perak Malaysia

ABSTRAT: Since 2011, we worked on imbalanced production data to forecast the product deficit without opening products, that is, by using a few features obtained. The sample number is quite large, but deficit products are not so many. The task is to impute some unknow values from imbalanced data set which optimize the result. Almost all the samples are good products. The given data set was imbalanced. In this talk we will report the successful approach to impute or forecast the values of given data.
