- Abstract
El proyecto consiste en el diseño, desarrollo e integración de diferentes modelos de avatares virtuales con algoritmos de inteligencia artificial (IA) conversacional. El principal objetivo es conseguir un avatar inteligente para facilitar el seguimiento con pacientes que sufren enfermedades mentales, como también el seguimiento clínico de los pacientes. Gracias a la plataforma OMNIVERSE de NVIDIA, concretamente Audio2face, se ha conseguido el desarrollo de la animación facial del modelo diseñado, como también, la integración con un sistema de IA. Se ha llegado a disponer de un avatar realista integrado en un entorno metaverso. El modelo es capaz de comunicarse de manera inteligente con los pacientes. En resumen, un asistente de servicio al paciente impulsado por inteligencia artificial listo para gestionar citas médicas, conversar de forma inteligente, ayudar al médico en la detección de enfermedades y proporcionar recomendaciones para mejorar la experiencia de servicio al cliente. El asistente virtual podrá proporcionar información y responder preguntas relacionadas con la salud y el bienestar. La inteligencia artificial no puede reemplazar la opinión de un médico profesional. Sin embargo, desempeñar un papel útil tanto para el médico como para el paciente. Una posibilidad consiste en preservar todos los datos relevantes captados por el asistente virtual en una base de datos, la cual posteriormente podría ser analizada por el médico designado. Al combinar ambas fuentes, se podría lograr una gestión de enfermedades más eficaz y ágil. El proyecto se enmarca en un mercado en crecimiento como es el de las aplicaciones del metaverso para salud y bienestar, tasado en 6 B$ en 2023, un crecimiento medio de 35,5% CGAR llegando alcanzar los 30 B$ para 2030. La futura comercialización de soluciones se realizará a través de las empresas beHIT y Top Doctors con una previsión de ingresos de 10 M€ para 2027, abriendo una oportunidad de rendimiento de inversión con un VAN de 11 M€, The project consists of the design, development, and integration of different models of virtual avatars with conversational artificial intelligence (AI) algorithms. The main objective is to create an intelligent avatar to facilitate follow-up with patients suffering from mental illnesses, as well as clinical monitoring of patients. Thanks to NVIDIA's OMNIVERSE platform, specifically Audio2face, the facial animation of the designed model has been developed, along with integration with an AI system. A realistic avatar integrated into a metaverse environment has been achieved. The model is capable of intelligent communication with patients. In summary, it is an AI-driven patient service assistant ready to manage medical appointments, engage in intelligent conversations, assist doctors in disease detection, and provide recommendations to enhance the customer service experience. The virtual assistant will be able to provide information and answer questions related to health and well-being. Artificial intelligence cannot replace the opinion of a medical professional. However, it can play a useful role for both the doctor and the patient. One possibility is to preserve all relevant data collected by the virtual assistant in a database, which could later be analyzed by the assigned doctor. By combining both sources, more effective and efficient disease management could be achieved. The project is part of a growing market for metaverse applications in healthcare and wellbeing, estimated to reach $6 billion in 2023, with an average annual growth rate (CAGR) of 35.5%, reaching $30 billion by 2030. The future commercialization of solutions will be carried out through companies like beHIT and Top Doctors, with projected revenues of €10 million by 2027, offering an investment return opportunity with a net present value (NPV) of €11 million and an internal rate of return (IRR) of 202%. The first product is expected to be marketed by March 2024 in the UAE or SA.

- Abstract
The amount of data in medical databases doubles every 20 months, and physicians are at a loss to analyze them. Also, traditional methods of data analysis have difficulty to identify outliers and patterns in big data and data with multiple exposure / outcome variables and analysis-rules for surveys and questionnaires, currently common methods of data collection, are, essentially, missing.Obviously, it is time that medical and health professionals mastered their reluctance to use machine learning and the current 100 page cookbook should be helpful to that aim. It covers in a condensed form the subjects reviewed in the 750 page three volume textbook by the same authors, entitled “Machine Learning in Medicine I-III” (ed. by Springer, Heidelberg, Germany, 2013) and was written as a hand-hold presentation and must-read publication. It was written not only to investigators and students in the fields, but also to jaded clinicians new to the methods and lacking time to read the entire textbooks.General purposes and scientific questions of the methods are only briefly mentioned, but full attention is given to the technical details. The two authors, a statistician and current president of the International Association of Biostatistics and a clinician and past-president of the American College of Angiology, provide plenty of step-by-step analyses from their own research and data files for self-assessment are available at extras.springer.com.From their experience the authors demonstrate that machine learning performs sometimes better than traditional statistics does. Machine learning may have little options for adjusting confounding and interaction, but you can add propensity scores and interaction variables to almost any machine learning method.

- Abstract
The amount of data medical databases doubles every 20 months, and physicians are at a loss to analyze them. Also, traditional data analysis has difficulty to identify outliers and patterns in big data and data with multiple exposure / outcome variables and analysis-rules for surveys and questionnaires, currently common methods of data collection, are, essentially, missing. Consequently, proper data-based health decisions will soon be impossible.Obviously, it is time that medical and health professionals mastered their reluctance to use machine learning methods and this was the main incentive for the authors to complete a series of three textbooks entitled “Machine Learning in Medicine Part One, Two and Three, Springer Heidelberg Germany, 2012-2013', describing in a nonmathematical way over sixty machine learning methodologies, as available in SPSS statistical software and other major software programs. Although well received, it came to our attention that physicians and students often lacked time to read the entire books, and requested a small book, without background information and theoretical discussions and highlighting technical details.For this reason we produced a 100 page cookbook, entitled'Machine Learning in Medicine - Cookbook One', with data examples available at extras.springer.com for self-assessment and with reference to the above textbooks for background information. Already at the completion of this cookbook we came to realize, that many essential methods were not covered. The current volume, entitled'Machine Learning in Medicine - Cookbook Two'is complementary to the first and also intended for providing a more balanced view of the field and thus, as a must-read not only for physicians and students, but also for any one involved in the process and progress of health and health care.Similarly to Machine Learning in Medicine - Cookbook One, the current work will describe stepwise analyses of over twenty machinelearning methods, that are, likewise, based on the three major machine learning methodologies:Cluster methodologies (Chaps. 1-3)Linear methodologies (Chaps. 4-11)Rules methodologies (Chaps. 12-20)In extras.springer.com the data files of the examples are given, as well as XML (Extended Mark up Language), SPS (Syntax) and ZIP (compressed) files for outcome predictions in future patients. In addition to condensed versions of the methods, fully described in the above three textbooks, an introduction is given to SPSS Modeler (SPSS'data mining workbench) in the Chaps. 15, 18, 19, while improved statistical methods like various automated analyses and Monte Carlo simulation models are in the Chaps. 1, 5, 7 and 8.We should emphasize that all of the methods described have been successfully applied in practice by the authors, both of them professors in applied statistics and machine learning at the European Community College of Pharmaceutical Medicine in Lyon France. We recommend the current work not only as a training companion to investigators and students, because of plenty of step by step analyses given, but also as a brief introductory text to jaded clinicians new to the methods. For the latter purpose, background and theoretical information have been replaced with the appropriate references to the above textbooks, while single sections addressing'general purposes','main scientific questions'and'conclusions'are given in place.Finally, we will demonstrate that modern machine learning performs sometimes better than traditional statistics does. Machine learning may have little options for adjusting confounding and interaction, but you can add propensity scores and interaction variables to almost any machine learning method.

- Abstract
Enormous advances in information technology have permeated essentially all facets of life in the past two decades. Formidable challenges remain in fostering tools that enhance productivity but are sensitive to work practices. Cognitive Informatics (CI) is the multidisciplinary study of cognition, information and computational sciences that investigates all facets of human computing including design and computer-mediated intelligent action, thus is strongly grounded in methods and theories from cognitive science. As an applied discipline, it has a close affiliation with human factors and human-computer interaction, and provides a framework for the analysis and modeling of complex human performance in technology-mediated settings and contributes to the design and development of better information systems. In recent years, CI has emerged as a distinct area with special relevance to biomedicine and health care. In addition, it has become a foundation for education and training of health informaticians, the Office of the National Coordinator for Health Information Technology initiating a program including CI as one of its critical elements to support health IT curriculum development. This book represents a first textbook on cognitive informatics and will focus on key examples drawn from the application of methods and theories from CI to challenges pertaining to the practice of critical-care medicine (CCM). Technology is transforming critical care workflows and re-organizing patient care management processes. CCM has proven to be a fertile test bed for theories and methods of cognitive informatics. CI, in turn, has contributed much to our understanding of the factors that result in complexity and patient errors. The topic is strongly interdisciplinary and will be important for individuals from a range of academic and professional backgrounds, including critical care specialists, psychologists, computer scientists, medical informaticians, and anthropologists.

- Abstract
Computer technology has impacted the practice of medicine in dramatic ways. Imaging techniques provide noninvasive tools which alter the di agnostic process. Sophisticated monitoring equipment presents new levels of detail for both patient management and research. In most of these tech nology applications, the computer is embedded in the device; its presence is transparent to the user. There is also a growing number of applications in which the health care provider directly interacts with a computer. In many cases, these appli cations are limited to administrative functions, e.g., office practice man agement, location of hospital patients, appointments, and scheduling. Nevertheless, there also are instances of patient care functions such as results reporting, decision support, surveillance, and reminders. This series, Computers and Medicine, will focus upon the direct use of information systems as it relates to the medical community. After twenty-five years of experimentation and experience, there are many tested applications which can be implemented economically using the current generation of computers. Moreover, the falling cost of computers suggests that there will be even more extensive use in the near future. Yet there is a gap between current practice and the state-of-the-art.

- Abstract
Traditional machine learning methods amongst others segment an image into different regions on basis of pixel attributes. One of the most well known methods are clustering and thresholding algorithms. Convolutional neural networks are designed to imitate the human visual cortex by applying convolutional filters in form of layers to the input images. That way, deep features are extracted. Since this process is often referred to a “black box” behaviour because it is unknown what is going on inside the model, deep learning interpretability methods are introduced that highlight parts of an image that are important for the algorithm’s classification process. Experiments show that it is possible to establish links between segmented regions extracted by traditional methods and deep features extracted by CNNs. These results rely heavily on the DL interpretability method used and the type of dataset. This extended TFM is carried out in cooperation with a research group from the AMRITA University – school of medicine in India, focusing on biomedical image processing and computer vision.

- Abstract
Skin cancer is a major public health issue with millions of cases diagnosed around the world. Melanoma is the most mortal form of skin cancer and causes the highest percentage of deaths. Although the mortality rate for melanoma is significant, when an early diagnosis is made more than the 95% of people survive. Therefore, a neural network image classification would be significantly helpful during diagnosis. Artificial neural networks have become a popular machine learning model due to the ability to make nonlinear and complex relationships between thousands of variables. In fact, on occasion convolutional neural networks pattern detection abilities surpass their human counterparts. The main objective of this thesis is to design a convolutional neural network which is able to distinguish melanoma from other skin lesions with a high rate of accuracy. Neural networks were trained and tested using images from HAM10000 dataset. Using a replicated factorial fractional design of experiments, we have realized the importance of balance in classification. Using different oversampling methods we have obtained a F1-score of 84% in the test data. As a result, we have demonstrated that it is possible to classify melanoma with greater precision. In fact, these results appear to be better than the usual results achieved through multi-class classification. Furthermore, we believe that with more computational capabilities better results could be reached, El càncer de pell és un problema important de salut pública, amb milions de casos diagnosticat sarreu del món. El melanoma és la forma més mortal de càncer de pell, responsable de la immensa majoria de les morts per càncer de pell.

Health coaching is a promising approach to support self-management of chronic conditions like type 2 diabetes; however, there aren’t enough coaching practitioners to support those in need. Advances in Artificial Intelligence (AI) and Machine Learning (ML) have the potential to enable innovative, automated health coaching interventions, but important gaps remain in applying AI and ML to coaching interventions. This thesis aims to identify computational approaches and interactive technologies that enable automated health coaching systems. First, I utilized computational approaches that leverage individuals’ self-tracking and health data and used an expert system to translate ML inferences into personalized nutrition goal recommendations. The system, GlucoGoalie, was evaluated in multiple studies including a 4-week deployment study which demonstrated the feasibility of the approach. Second, I compared human-powered and automated/chatbot approaches to health coaching in a 3-week study which found that t2.coach — a scripted, theoretically-grounded chatbot designed through an iterative, user-centered process — cultivated a coach-like experience that had many similarities to the experience of messaging with actual health coaches, and outlined directions for automated, conversational coaching interventions. Third, I examined multiple AI approaches to enable micro-coaching dialogs — brief coaching conversations related to specific meals, to support achievement of nutrition goals — including a knowledge-based system for natural language understanding, and a data-driven, reinforcement learning approach for dialog management. Together, the results of these studies contribute methods and insights that take steps towards more intelligent conversational coaching systems, with resonance to research in informatics, human-computer interaction, and health coaching.

Breast cancer is considered one of the deadliest cancers among females. Despite the advanced achievement in the field of medical imaging analysis, a few early research works proposed semi-automatic machine learning algorithms that were complex and computationally expensive. Recently, developing a system based on deep learning concepts was the center of the attention to analyze mammograms, which is the golden standard imaging technique to diagnose the existence of an abnormality in breast tissues. Systems based on deep learning are still considered to be limited due to insufficient datasets. In this study, numerous experiments were made on small size ROI samples of mammogram images in the CBIS-DDSM dataset to find the best configuration of a pre-trained Convolutional Neural Network with ImageNet dataset. The main training concept is about extracting standard features automatically by striding filters over the input matrix (mammogram). Thus, a larger number of inputs lead to recognize a useful pattern to classify the abnormality. The pre-trained models along with data augmentation algorithms are applied to minimize the dataset challenge in the breast cancer diagnosing field. On the other hand, image preprocessing techniques helped to enhance the image inputs. The study addresses two pre-trained models VGG16 and ResNet50, both were fine-tuned in different depths and hyper-parameters. The experimental results obtained with good performance used a VGG16 pre-trained model after fine-tuning the last fully connected layer. The proposed VGG16 model outperformed other deep learning algorithms with an F1 score and AUC of 82% when classifying the abnormality type into calcification/ mass. The model has also a high score with a mean AUC equal to 0.80 when classifying the mammograms into four classes: benign calcification, malignant calcification, benign mass, and malignant mass. The final application in this study tries to assist radiologists to accomplish more precise decision on the abnormality pathology of breast lesions present in full mammogram images. The application also helps in reducing diagnosing time hence increasing the early detection time. Keywords: CNN, Transfer Learning, Breast Abnormality, Classification, Mammograms, Calcification, Mass. ÖZ: Göğüs kanseri, kadınlar arasında ölümcül kanserlerden biri olarak kabul edilir. Tıbbi görüntüleme analizi alanındaki gelişmiş başarıya rağmen, birkaç araştırma çalışması, karmaşık ve hesaplama açısından pahalı olan, yarı otomatik makine öğrenim algoritmaları önermişlerdir. Son zamanlarda, derin öğrenme kavramlarına dayalı bir sistem geliştirmek ilgi odağı olmuştur. Bununla birlikte, bu sistemler, çoğunlukla mamografi görüntülerini analiz eder ve meme anormalliğinin varlığını teşhis etmek için altın standart, mevcut veri setlerinin yetersiz olması nedeniyle hala sınırlı olduğu düşünülmektedir. Bu çalışmada, ImageNet veri kümesiyle önceden eğitilmiş evrişimli sinir ağına dayalı bir transfer öğrenme modelinin en iyi modelini bulmak için, CBIS-DDSM veri kümesindeki mamogram görüntülerinin küçük boyutlu ROI örnekleri üzerinde çok sayıda deney yapılmıştır. Eğitim veri seti, giriş matrisi (bir mamogram görüntüsü) üzerinden filtreler ilerletilerek standart özelliklerin otomatik olarak çıkarılmasında kullanılır. Bu nedenle, daha fazla sayıda girdi, anormalliği sınıflandırmak için kullanışlı bir modelin ortaya çıkmasına yol açar. Göğüs kanseri teşhisi alanında veri seti elde etme zorluğunu en aza indirmek için uygulanan veri büyütme algoritmalarıyla birlikte önceden eğitilmiş modellerin kullanımı sağlandı. Öte yandan, görüntü ön işleme teknikleri görüntü girdilerini istenen forma getirmek için uygulandı. Bu çalışmada, önceden eğitilmiş iki ana model senaryosu ele alınmıştır; VGG16 ve ResNet50. Her ikisi de farklı derinliklerde ve hiper parametrelerinde ince ayarlamalar yapılarak uygulanmıştır. Önceden eğitilmiş VGG16 modeli ile, deneysel çalışmalarımız sonucunda, son tam bağlı katmanı üzerinde ince ayarlar yapıldıktan sonra, iyi performans değerleri elde edilmiştir. Önerilen VGG16 modeli, anormallik türünü kalsifikasyon / kütle olarak sınıflandırmasını yaparken, F1 skoru ve AUC değeri %82 olarak elde edilmiş, diğer derin öğrenme algoritmalarından daha iyi performans göstermiştir. Model ayrıca mamogramları dört grupta sınıflandırırken, ortalama AUC değeri %80 olarak hesaplanmış ve yüksek bir performans elde edilmiştir. Önerilen model ile, “iyi huylu kalsifikasyon”, “kötü huylu kalsifikasyon”, “iyi huylu kitle”, ve “kötü huylu kitle” sınıflandırması yapılmıştır. Radyologların meme lezyonlarının anormal patolojisi hakkında daha kesin karar vermelerine yardımcı olmak için nihai bir uygulama yapılmış ve tam mamografi görüntüsü göstermektedir. Uygulama aynı zamanda teşhis süresinin azaltılmasına ve dolayısıyla erken tespit süresinin artmasına da yardımcı olur.

The increasing availability of microbiome survey data has led to the use of complex machine learning and statistical approaches to measure taxonomic diversity and extract relationships between taxa and their host or environment. Accurately representing microbiome community structure has notable implications in medicine because recent work has demonstrated bidirectional interplay between microbiota and various organ systems. However, many approaches inadequately account for difficulties inherent to microbiome data, such as (1) insufficient sequencing depth resulting in sparse count data, (2) a large feature space relative to sample space, resulting in data prone to overfitting, and (3) library size imbalance, requiring normalization strategies that lead to compositional artifacts. Still, there exist approaches from other domains (e.g., natural language processing) that may be well-equipped at fitting microbiome data and may provide meaningful features that capture relevant aspects of the data. Two methods in particular are topic models and word embeddings, which characterize word co-occurrence as topics and capture semantic and lexical information of each word based on the word's neighbors, respectively. In this work, we show that a topic model can represent microbiome abundance data as topics, capturing ``subcommunity'' structure from co-occurrence patterns among taxa, whereas word embeddings can represent a nucleotide subsequence as a dense, numeric vector that encapsulates the nucleotide neighborhood in which the subsequence exists. Specifically, we present two approaches, both of which are applied to 16S rRNA amplicon surveys. First, we utilize a topic model approach. We show that library-size normalization is unnecessary and, by exploiting topic-to-topic correlations, the topic model can successfully capture complex signals such as dynamic time-series behavior of taxonomic subcommunities. In addition, we present themetagenomics to demonstrate that topic features are flexible for downstream analysis. We link taxonomic co-occurrence to their predicted functional content by leveraging gene function prediction algorithms and a fully Bayesian multilevel regression model. Second, we use Skip-Gram word2vec and a recent sentence embedding approach to embed nucleotide sequences. Our results show that embedding sequences results in meaningful representations that can be used for exploratory analyses or for downstream machine learning applications that require numeric data. The sequence embeddings can preserve relevant information about the sequencing data such as k-mer context, sequence taxonomy, and sample class. The insights we provide are applicable to various types of count data that extend beyond the microbiome sequencing domain. These include ecological presence/absence surveys, RNAseq gene expression studies, metagenomic or whole genome sequencing studies, proteomic or metabolic research, text-based studies, and econometrics. In addition, our approaches for exploring the sequence embedding space are applicable to any type of text-base research, including genetics and natural language processing, as well applications utilizing deep learning, where embedding layers are used to encode text for deeper layers of the network. Lastly, our simulation approaches and evaluation of normalization techniques are generalizable, such that aspects of these strategies could be applied to microbiome studies and work consisting of compositional data other than 16S rRNA amplicon surveys.

Ankara : The Department ofIndustrial Engineering, Bilkent University, 2012. Thesis (Master's) -- Bilkent University, 2012. Includes bibliographical references leaves 54-56. In this research a prediction model for cellular uptake efficiency of nanoparticles (NPs), which is the rate of NPs adhered to the cell surface or entered into the cell, is investigated via Artificial Neural Network (ANN) method. Prediction of cellular uptake rate of NPs is an important study considering the technical limitations of volatile environment of organism and the time limitation of conducting numerous experiments for thousands of possible variations of different variables that have an impact on NP uptake rate. Moreover, this study constitutes a basis for the targeted drug delivery and cell-level detection, treatment and diagnoses of existing pathologies through simulating experimental procedure of NP-Cell interactions. Accordingly, this study will accelerate nano-medicine researches. The research focuses on constructing a proper ANN model based on multilayered feed-forward back-propagation algorithm for prediction of cellular uptake efficiency which depends on NP type, NP size, NP surface charge, concentration and time. NP types for in-vitro NP-healthy cell interaction analysis are polymethyl methacrylate (PMMA), silica and polylactic acid (PLA) all of whose shapes are spheres. The proposed ANN model has been developed on MATLAB Programming Language by optimizing number of hidden layers, node numbers and training functions. The data sets for training and testing of the network are provided through in-vitro NP-cell interaction experiments conducted by a Nano-Medicine Research Center in Turkey. The dispersion characteristics and cell interactions of the different nanoparticles in organisms are explored through constructing and implementing an optimal prediction model using ANNs. Simulating the possible interactions of targeted nanoparticles with cells via ANN model could lead to a more rapid, more convenient and less expensive approach in comparison to numerous experimental variations.
