What is KNOWLEDGE DISCOVERY? What does KNOWLEDGE DISCOVERY mean? KNOWLEDGE DISCOVERY meaning - KNOWLEDGE DISCOVERY definition - KNOWLEDGE DISCOVERY explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. nowledge discovery describes the process of automatically searching large volumes of data for patterns that can be considered knowledge about the data. It is often described as deriving knowledge from the input data. Knowledge discovery developed out of the data mining domain, and is closely related to it both in terms of methodology and terminology. The most well-known branch of data mining is knowledge discovery, also known as knowledge discovery in databases (KDD). Just as many other forms of knowledge discovery it creates abstractions of the input data. The knowledge obtained through the process may become additional data that can be used for further usage and discovery. Often the outcomes from knowledge discovery are not actionable, actionable knowledge discovery, also known as domain driven data mining, aims to discover and deliver actionable knowledge and insights. Another promising application of knowledge discovery is in the area of software modernization, weakness discovery and compliance which involves understanding existing software artifacts. This process is related to a concept of reverse engineering. Usually the knowledge obtained from existing software is presented in the form of models to which specific queries can be made when necessary. An entity relationship is a frequent format of representing knowledge obtained from existing software. Object Management Group (OMG) developed specification Knowledge Discovery Metamodel (KDM) which defines an ontology for the software assets and their relationships for the purpose of performing knowledge discovery of existing code. Knowledge discovery from existing software systems, also known as software mining is closely related to data mining, since existing software artifacts contain enormous value for risk management and business value, key for the evaluation and evolution of software systems. Instead of mining individual data sets, software mining focuses on metadata, such as process flows (e.g. data flows, control flows, & call maps), architecture, database schemas, and business rules/terms/process.

09:10
Andreas Holzinger promotes a synergistic approach by integration of two areas to understand intelligence to realize context-adaptive systems: Human-Computer Interaction (HCI) & Knowledge Discovery/Data Mining (KDD). Andreas has pioneered in interactive machine learning (iML) with the human-in-the-loop. Andreas Holzingers’ goal is to augment human intelligence with artificial intelligence to help to solve problems in health informatics. Due to raising legal and privacy issues in the European Union glass box AI approaches will become important in the future to be able to make decisions transparent, re-traceable, thus understandable. Andreas Holzingers’ aim is to explain why a machine decision has been made, paving the way towards explainable AI. 00:34 [1] June-Goo Lee, Sanghoon Jun, Young-Won Cho, Hyunna Lee, Guk Bae Kim, Joon Beom Seo & Namkug Kim 2017.

Reda Alhajj Department of Computer Science, the University of Calgary CANADA Title Facilitating Big Data Analysis Using Limited Computing Resources Abstract The rapid development in technology and social media has gradually shifted the focus in research, industry and community from traditional into dynamic environments where creativity and innovation dominate various aspects of the daily life. This facilitated the automated collection and storage of huge amount of data which is necessary for effective decision making. The value of data is increasingly realized and there is a tremendous need for effective techniques to maintain and handle the collected data starting from storage to processing and analysis leading to knowledge discovery. This talk will focus on techniques and structures which could maximize the benefit from data beyond what is traditionally supported. We emphasize on data intensive domains which require developing and utilizing advance computational techniques for informative discoveries. We describe some of our accomplishments, ongoing research and future research plans. The notion of big data will be addressed to show how it is possible to process incrementally available big data using limited computing resources. The benefit of various data mining and network modeling mechanisms for data analysis and prediction will be addressed with emphasize on some practical applications ranging from forums and reviews to social media as effective means for communication, sharing and discussion leading to collaborative decision making and shaping of future plans.

Data mining
 
47:46
Data mining (the analysis step of the "Knowledge Discovery in Databases" process, or KDD), an interdisciplinary subfield of computer science, is the computational process of discovering patterns in large data sets involving methods at the intersection of artificial intelligence, machine learning, statistics, and database systems. The overall goal of the data mining process is to extract information from a data set and transform it into an understandable structure for further use. Aside from the raw analysis step, it involves database and data management aspects, data pre-processing, model and inference considerations, interestingness metrics, complexity considerations, post-processing of discovered structures, visualization, and online updating. The term is a misnomer, because the goal is the extraction of patterns and knowledge from large amount of data, not the extraction of data itself. It also is a buzzword, and is frequently also applied to any form of large-scale data or information processing (collection, extraction, warehousing, analysis, and statistics) as well as any application of computer decision support system, including artificial intelligence, machine learning, and business intelligence. The popular book "Data mining: Practical machine learning tools and techniques with Java" (which covers mostly machine learning material) was originally to be named just "Practical machine learning", and the term "data mining" was only added for marketing reasons. Often the more general terms "(large scale) data analysis", or "analytics" -- or when referring to actual methods, artificial intelligence and machine learning -- are more appropriate.

Symmetry Group-based Learning for Regularity Discovery from Real World Patterns
 
01:14:14
Google Tech Talks December 15, 2008 ABSTRACT We explore a formal and computational characterization of real world regularity using discrete symmetry groups (hierarchy) as a theoretical basis, embedded in a well-defined Bayesian framework. Our existing work on "A Computational Model for Periodic Pattern Perception Based on Frieze and Wallpaper Groups" (TPAMI 2004), 'Near-regular texture analysis and manipulation' (SGIGRAPH 2004), and "A Lattice-based MRF Model for Dynamic Near-regular Texture Tracking" (PAMI 2007) already demonstrate the power of such a formalization on a diverse set of real problems, such as texture analysis, synthesis, tracking, perception and manipulation in terms of regularity. Symmetry and symmetry group detection from real world data turns out to be a very challenging problem that has been puzzling computer vision researchers for the past 40 years. Our novel formalization will lead the way to a more robust and comprehensive algorithmic treatment of the whole regularity spectrum, from regular (perfect symmetry), near-regular (deviations from symmetry), to various types of irregularities. The recent results of the proposed methodology will be illustrated in this talk by several real world applications such as deformed lattice detection, rotation and glide-reflection detection, gait recognition, grid-cell clustering, symmetry of dance, automatic geo-tagging and image de-fencing. Speaker: Yanxi Liu Yanxi Liu received her B.S. degree in physics/electrical engineering and her Ph.D. degree in computer science for group theory applications in robotics (UMass Amherst). Her postdoctoral training was performed in LIFIA/IMAG, Grenoble, France.

Intelligible Models for HealthCare: Predicting Pneumonia Risk and Hospital 30-day Readmission
 
23:58
Authors: Rich Caruana, Yin Lou, Johannes Gehrke, Paul Koch, Marc Sturm, Noemie Elhadad Abstract: In machine learning often a tradeoff must be made between accuracy and intelligibility. More accurate models such as boosted trees, random forests, and neural nets usually are not intelligible, but more intelligible models such as logistic regression, naive-Bayes, and single decision trees often have significantly worse accuracy. This tradeoff sometimes limits the accuracy of models that can be applied in mission-critical applications such as healthcare where being able to understand, validate, edit, and trust a learned model is important. We present two case studies where high-performance generalized additive models with pairwise interactions (GA2Ms) are applied to real healthcare problems yielding intelligible models with state-of-the-art accuracy. In the pneumonia risk prediction case study, the intelligible model uncovers surprising patterns in the data that previously had prevented complex learned models from being fielded in this domain, but because it is intelligible and modular allows these patterns to be recognized and removed. In the 30-day hospital readmission case study, we show that the same methods scale to large datasets containing hundreds of thousands of patients and thousands of attributes while remaining intelligible and providing accuracy comparable to the best (unintelligible) machine learning methods.

Recent Advances in Data Assimilation
 
01:00:47
The improvement in numerical weather prediction in the last three decades is due to improvements in atmospheric models, observations and data assimilation (the science of combining forecasts and observations to create model initial conditions). In recent years, the Ensemble Kalman filter has become the most advanced approach for performing data assimilation. I will introduce data assimilation, Ensemble Kalman filters and new advances that extend their usefulness. In addition, I will show application of these algorithms to real and simulated observation examples, illustrating the potential of these new approaches. The results include seven years of global ocean data assimilation, estimation of surface carbon, heat and moisture fluxes from atmospheric data assimilation, and a comparison of fourdimensional variational data assimilation (4D-Var) and an Ensemble Kalman filter for a simple "coupled ocean-atmosphere model". About Dr. Eugenia Kalnay Eugenia Kalnay is a Distinguished University Professor in the Department of Atmospheric and Oceanic Science at the University of Maryland. For ten years she served as Director of the Environmental Modeling Center within the National Weather Service, which is a pioneer in both the fundamental science and practical applications of numerical weather prediction. In 2009, Dr. Kalnay won the prestigious World Meteorological Organization IMO Prize. Her work on the impact of land use on climate change was chosen by Discovery Magazine as one of the top 100 science results of the year, and her seminal paper on reanalysis is the most cited paper in geosciences. Dr. Kalnay was the first woman to obtain a doctorate from the MIT Department of Meteorology (1971) and the first female professor there. Her current research interests lie in data assimilation, numerical weather prediction, coupled ocean-atmosphere modeling and climate change. This lecture is part of the seminar series at NASA Jet Propulsion Laboratory's Center for Climate Sciences. Lecture Date: February 15, 2012 http://climatesciences.jpl.nasa.gov

"A Systems Approach to Data Privacy in the Biomedical Domain" (CRCS Lunch Seminar)
 
01:10:06
CRCS Privacy and Security Lunch Seminar (Wednesday, May 13, 2009) Speaker: Bradley Malin Title: A Systems Approach to Data Privacy in the Biomedical Domain Abstract: The healthcare community has made considerable strides in the development and deployment of information systems, with particular gains in electronic health records and cheap genome sequencing technologies. Given the recent passage of the American Recovery and Reinvestment Act of 2009, and the HITECH Act in particular, advancement and adoption of such systems is expected to grow at unprecedented rates. The quantity of patient-level data that will be generated is substantial and can enable more cost-effective care as well as support a host of secondary uses, such biomedical research and biosurveillance. At the same time, care must be taken to ensure that such records are accessed and shared without violating a patient's privacy rights. The construction and application of data privacy technologies in the biomedical domain is a complex endeavor and requires the resolution of often competing computational, organizational, regulatory, and scientific needs. In this talk, I will introduce how the Vanderbilt Health Information Privacy Laboratory builds and applies data privacy solutions to support various biomedical settings. Our solutions are rooted in computational formalisms, but are driven by real world requirements and, as such, draw upon various tools and techniques from a number of fields, including cryptography, databases and data mining, public policy, risk analysis, and statistics. Beyond a high-level overview, I will delve into recent research on how we are measuring and mitigating privacy risks when sharing patient-level data from electronic medical and genomic records from the Vanderbilt University Medical Center to local researchers and an emerging de-identified repository at the National Institutes of Health. Bio: Brad Malin is an Assistant Professor of Biomedical Informatics in the School of Medicine and an Assistant Professor of Computer Science in the School of Engineering at Vanderbilt University. He is the founder and director of the Vanderbilt Health Information Privacy Laboratory (HIPLab), which focuses on basic and applied research in a number of health-related areas, including primary care and secondary sharing of patient-specific clinical and genomic data. His research has received several awards of distinction from the American and International Medical Informatics Associations and the HIPLab is currently supported by grant funding from the National Science Foundation, National Institutes of Health, and Veterans Health Administration. For the past several years, he has directed a data privacy research and consultation team for the Electronic Medical Records and Genomics (eMERGE) project, a consortium sponsored by the National Human Genome Research Institute. He has served as a program committee member and workshop chair for numerous conferences on data mining, privacy, and medical informatics. He has also edited several volumes for Springer Lecture Notes in Computer Science, a special issue for the journal Data and Knowledge Engineering, and is currently on the editorial board of the journal Transactions on Data Privacy. He received a bachelor's in biology (2000), master's in knowledge discovery and data mining (2002), master's in public policy & management (2003), and a doctorate in computation, organizations & society (2006) from the School of Computer Science at Carnegie Mellon University.

Author Sagar Gajera, Manmay Badheka, L J Institute of Engineering and Technology, Ahmedabad, India {sdgajera14, manmaybadheka}@gmail.com ABSTRACT In Present, so many techniques are available which can be applicable to wide range of datasets. They provide effective way to mine frequent pattern from the datasets. Most of them use different kind of data structures for the processing which provide variations in requirement of time and space. Generally, traditional techniques are restricted to the narrow area or provide effective results only in the specific environment. So, it requires continuous optimization and updation. Dynamic data structure and mapping shows more effectiveness compared to the traditional techniques in terms of time and space requirement for processing.

Title: Applications of genomics and future prospects 2nd International Conference on Genomics & Pharmacogenomics, September 08-10, 2014, Doubletree by Hilton Hotel Raleigh-Brownstone-University, USA OMICS International: http://omicsonline.org Vaccine Conferences: http://conferenceseries.com/immunology-conferences.php Global Medical Conferences: http://conferenceseries.com Global Pharmaceutical Conferences: http://pharmaceuticalconferences.com Global Cancer Conferences: http://cancersummit.org Global Diabetes Conferences: http://diabetesexpo.com Global Dental Conferences: http://dentalcongress.com Global Nursing Conferences: http://nursingconference.com Abstract: Applications of genomics include clinical genetics, disease gene discovery, identifying gene regulatory systems, and Evolutionary analysis. The two areas of paramount interest are (a) vaccine development for preventing infections which are major killers such as the malaria parasites and HIV virus, and (b) cancer genomics. A comprehensive analysis of the cancer genome remains a daunting challenge. There is no single technology at present that will detect all the types of abnormality-deletions, rearrangements, point mutations, frame shift insertions, amplifications, imprinting, and epigenetic changes implicated in cancer. Microarrays and gene chip analysis, however, are beginning to unveil some key genomic drivers. Many clinical trials now include genomic profiles of cancer patients as prognostic and diagnostic indicators, which are playing an increasing role in defining pharmacogenomics. Genomic profiles are useful in monitoring where and how the cancer genome has been hit during molecularly targeted therapies. Data-Mining and sharing these data should eventually help to better integrate the genotypic and phenotypic changes that occur in a during cancer’s progression. Genetic variability revealed in the newly sequenced malaria genomes indicates new challenges in efforts to eradicate the parasite, but also offers a clearer and more detailed picture of its genetic composition, providing an initial roadmap in the development of pharmaceuticals and vaccines to combat malaria. Recent studies have focused attention on Plasmodium vivax, a species of malaria that afflicts humans and the most prevalent human malaria parasite outside Africa, and Plasmodium cynomolgi, a close relative that infects Asian Old World monkeys. However, what has been revealed is both bad and good. The bad news is that there is significantly more genetic variation in P. vivax than what had been expected, which increases the likelihood of the pathogen evading whatever drugs and vaccines we may use. The good news is that we have gained greater knowledge of the challenges we will be facing and we can move forward with more confidence in designing more effective remedies. Research at The Sanger Institute in the U.K. has produced the world’s largest resource of malaria parasite genomic data, comprising over 3,000 genomes to date. The level of detail, both genomic and geographical, afforded by this project has enabled new levels of genetic analysis. The relationship between clinical research and genomics is at a turning point in malaria, offering much promise for future advances.

Query Model for Image Search based on User Clicks and NN Features - Dmitry Krivokon
 
04:22
Yandex School of Data Analysis Conference Machine Learning: Prospects and Applications https://yandexdataschool.com/conference We consider a problem of improving the quality of a query-based image search engine by using user click data. The primary purpose of an image search engine (SE) is to assist in finding images that are relevant to the text query entered by a user (such SEs should not be confused with content base image retrieval [10]). The resulting images ideally should be sorted by their relevance in descending order, hence the main task of the SE is to determine the relevance (or rank [3]) of a particular image to the particular query. A lot of information about image relevance to the query can be deduced from the actions performed by a user while browsing the results of the SE. User clicks on a specific result can be considered as a strong signal of the image relevance. The abundance of this data in large SEs leaves a lot of space for different strategies for its adaptation to the ranking problem [2, 4]. We propose to use click data to construct a vector space representation of a query based on the content of the images on which the user clicked viewing the results of the search engine for the query. Document [8] and query models [9] are popular means to solve classification and cluster- ing problems, however, we apply our technique to directly compare a query and some image to understand their “similarity” to each other. To represent the content of an image we use one of the final layers of deep convolutional neural network [6] trained on the standard ImageNet data- set [1]. Essentially this representation is just a 100-dimensional vector of real values. Usage of this type of features became a generally accepted practice in various tasks of image classification and recognition. Besides, they are also generally used as the basis for image search engines that find images visually similar to the “query” image [10]. Such successful applications motivated our approach. Our query model is constructed by aggregating the feature vectors of all clicked images for a particular query. Having such a model, which by design resides in the same vector space as the image features used for its construction, allows for calculation of the direct distance between a query and a specific image. This distance can be used as a feature in a search engine ranker [2] or can be used to re-rank the top ranked images returned by such ranker [2, 5]. Having huge amounts of historical click data allows mitigation of the negative effects of noise that is naturally present in user data and even in the responses of the neural network. In addition, we use not only the features of a specific image on which users clicked but also the features of the image duplicates [7] found in the search engine database. That leads to even better quality of the resulting model. We analyze and compare several aggregation strategies and show the performance of our approach on standard type datasets by measuring NDCG [3] and MSE metrics. 1.

Deep Learning for Multimedia Data: Teaching Computers to Sense Omar Florez Intel Labs. California USA email: [email protected] Schedule:Wed [email protected]:00, Room: A For the past few years, deep learning has been making rapid progress in both techniques and applications; significant performance gains were reported using deep learning in automatic speech recognition and image recognition over hand-optimized feature representations. Advances in smartphones, tablets, and wearables have made possible to sense a rich collection of user data, examples include audio, images, and video. This information allows us to infer user contexts such as faces, semantic locations, activities, and mood states enabling better and personalized user experiences. This explains the growing interest of industry (Intel, Facebook, Google, NVIDIA, Spotify, Netflix, Baidu, etc.) trying to take advantage of deep learning capabilities in recent years. In several image and speech tasks, the success of deep learning is due to its ability to learn representations from noisy and unstructured data. Context sensing faces the same problem therefore we believe applications of deep learning in this domain can be advantageous. During this talk we will try bringing together researchers and applicants to discuss some of the deep learning algorithms and capabilities for multimedia and context domains as well as explore possible new research areas.
