Data Curation in the Biomedical Sciences: from Text to Databases to Knowledge Discovery

Abstract: Knowledge discovery in the biomedical sciences depends on accurate, consistent representation of data in knowledgebases. Over the past two decades the biocuration community, including the Model Organism Databases (MODs) and the Gene Ontology Consortium (GOC) (http://geneontology.org/), have been at the forefront of biological knowledge management. The vast and rapidly increasing amount of biomedical data, however, makes biocuration a very challenging task. In my talk, I’ll discuss methods we’ve employed at WormBase (https://wormbase.org) and the GOC to help meet these challenges, with specific emphasis on the use of: 1) text mining tools, such as Textpresso (http://textpresso.org/), to identify suitable papers and evidence sentences for curation, 2) controlled vocabularies and ontologies to model biological data, and 3) data capture, visualization, and analysis tools to engage users and foster knowledge discovery.

Bio: Kimberly Van Auken, Ph.D. is a Database Curator for WormBase, the online database housing the genetics, genomics and biology of Caenorhabditis elegans and other nematodes. She serves as an ontology editor and co-manager of the Annotation Working Group for the Gene Ontology Consortium and is a member of the editorial board for ‘Database: The Journal of Biological Databases and Curation’.

Fast Time to Value – Splunk brings Machine Learning to Machine Data

Abstract: Splunk has been quietly developing use cases that offer companies visibility for their Machine Learning Data. Best known for their Security SIEM tool, which is considered a leading product in the security industry, more recently Splunk has introduced products to fit IT Operations Analytics use cases. By weaving machine learning into auto-baselining “normal” from “abnormal” activity throughout the data center, Splunk has been able to provide high-value data science to problems that were previously solved by anecdotal experience or gut instinct. Last year, Splunk launched their Machine Learning Toolkit which allowed Splunkers to leverage machine learning libraries to make reliable analysis and predictions with complex datasets. From linear regression to cluster analysis and outlier detection, Splunk provides the ability to automatically determine the accuracy of the models that are built. Splunk includes a development API where interested data scientists can plug in new ML algorithms and expose them in the toolkit. This talk will give you an overview of Splunk, what’s included in the toolkit, and how Industry is using it. You will also see how customers with no data science experience can deploy the tool to leverage Machine Learning with their data and how to utilize the dev API. In addition we will answer any questions about use cases seen and lessons learned.​

Data Science Applications in Healthcare: Improving Access, Performance, and Resource Deployment

Abstract: Large healthcare systems collect a wealth of data related to nearly all contact with patients, yet frequently struggle with the translation into useful knowledge. As organizations shift away from a model of fee-for-service and towards a new paradigm of accountable care, it will be increasingly important that they can a) preserve or improve access for patients, and b) assess performance on scales from the individual physician up to the entire system. Problems involving missing data, forecasts of operations or performance, and the added value of partnering with nearby institutions all present opportunities for the application of novel solutions to some of the most challenging issues in the contemporary healthcare environment. In this talk, Eric will outline current efforts at PAMF to model and forecast access in primary and specialty care, as well as assess the performance of surgeons and hospitalists operating in local hospitals. He will also discuss forecasting performed on behalf of a major solid organ transplant center in attempts to assure regulatory compliance and outperform the competition on standard metrics.

Philip Beesley | Professor in Architecture at the University of Waterloo, Professor of Digital Design and Architecture & Urbanism at the European Graduate School | LinkedIn

Sentient Architecture

Abstract: Philip Beesley of Waterloo Architecture will present recent work by the Living Architecture Systems group that explores a new generation of sentient architectural environments. Working with artists, engineers and scientists, the research collective combines the crafts of lightweight textile structures, dense arrays of distributed computer controls with machine learning, and artificial-life chemistry. New architectural installations within the collaboration feature dense reticulated grottos with breathing, reactive, near-living qualities. Thin layers of hovering filters are tuned for delicate kinetic and chemical responses in the form of expanded physiologies, beckoning and sharing space with viewers.

The presentation will suggest that conception of buildings can move from classical ideas of a static world of closed boundaries toward the expanded physiology and dynamic form of a metabolism. The architecture of historical Humanism encouraged stripped surfaces supporting free human action. The systems that appear within life-giving forests and jungles seem opposite to the rigid, stable enclosures of classically defined building. Instead of valuing resistance and closure, design for thermal exchange could result in new form-languages based on maximum interaction. Architecture could be founded on adaptation and uncertainty where acquiring and shedding heat play in uneven cycles. The kind of diffusive forms seen in reticulated snowflakes and the microscopic manifolds of mitochondria have a common form-language of radical exfoliation. Their increased surface areas can make their reaction-surfaces potent. These kinds of forms offer delicacy, resonance and resilience.

Writ large, these forms speak of involvement with the world. A new city designed to easily handle unstable conditions of shedding heat and cooling and then rapidly warming up and collecting heat again might well look like a hybrid forest where each building is made from dense layers of ivy-like filters and multiple overlapping layers of porous openings. A building system using an expanded range of reticulated screens and canopies is implied, constructed from minutely balanced filtering layers that can amplify and guide convective currents encircling internal spaces.

Bio: Philip Beesley, MRAIC OAA RCA, is a practicing visual artist, architect, and Professor in Architecture at the University of Waterloo and Professor of Digital Design and Architecture & Urbanism at the European Graduate School.

He serves as the Director for the Living Architecture Systems Group, and as Director for Riverside Architectural Press. His Toronto-based practice, Philip Beesley Architect Inc., operates in partnership with the Europe-based practice Pucher Seifert and the Waterloo-based Adaptive Systems Group, and in numerous other collaborations. The studio’s methods incorporate industrial design, digital prototyping, and mechatronics engineering. Beesley frequently collaborates with artists, scientists and engineers. Recent projects include a series of hybrid fabrics developed with Atelier Iris van Herpen, curiosity-based machine learning environments developed with Rob Gorbet and Dana Kulic of the Adaptive Systems Group, and synthetic metabolisms developed with Rachel Armstrong of the University of Newcastle. His most recent collaboration with Iris Van Herpen has translated a shared sensibility for subtle materials, electricity, and chemistry into a collection of highly complex and diverse textile and haute couture collections.

His research focuses on responsive and distributed architectural environments and interactive systems, flexible lightweight structures integrating kinetic functions, microprocessing, sensor and actuator systems, with particular focus on digital fabrication methods and sheet-material derivations. Beesley has authored and edited sixteen books and proceedings, and has appeared on the cover of Artificial Life (MIT), LEONARDO and AD journals. Features include national CBC news, Vogue, WIRED, and a series of TED talks. His work was selected to represent Canada at the 2010 Venice Biennale for Architecture, and has received distinctions including the Prix de Rome, VIDA 11.0, FEIDAD, Azure AZ, and Architizer A+.

Dan Putler | Chief Scientist at Alteryx | LinkedIn

Projecting Election Polling Results to Small Geographic Areas

Abstract: Election polling generally provides a useful means of predicting voter behavior nationally and at the state level. However, due to limited sample sizes and the cost associated with polling, understanding and predicting voter behavior at a “hyper local” level is not generally done – but this information would be invaluable for better focusing grassroots campaign activities such as door-to-door canvasing, get out the vote efforts, and yard signs and other outdoor media. In this work we set out to develop a model to make election predictions at a very localized level. Our solution to the problem accomplishes this in two parts: the first is the creation of a predictive model of voter choice based on both local area factors (such as county level Partisan Voting Index values) as well as individual demographic/socioeconomic characteristics; and the second is estimating the number of individuals that fall into specific demographic/socioeconomic profiles within each small geographic unit.
Our final model predicts voting outcomes at the census tract level (which typically have populations of around 4000 people), the results of which will be available for the public to explore in an interactive web app on the Alteryx Gallery. In this talk we will be looking at the approach and methodologies used to develop these predictions around the upcoming election, which were implemented using a combination of R and Alteryx. In addition, if time permits, an assessment of the predictive capability of the approach relative to the actual November 8 election results at the county level (the lowest level of geography for which election returns are generally available) will be presented.

Bio: Dr. Dan Putler is the Chief Scientist at Alteryx, where he is responsible for developing and implementing the product road map for predictive analytics. He has over 30 years of experience in developing predictive analytics models for companies and organizations that cover a large number of industry verticals, ranging from the performing arts to B2B financial services.

Learning Representations for Large-Scale Networks

Abstract: Recent successes in big data analytics and representation learning have drawn lots of attention. While deep learning techniques have demonstrated their great power in image, text, and speech data, finding methods of learning useful representations for discrete networked data remains a major challenge. In this talk, Dr. Mei will introduce recent progress made by his research group in learning the representations for large-scale network data. He will introduce efficient algorithms that embed nodes into a continuous vector space so that the local and global structural information is preserved. By further projecting the representation to a 2D space, we are able to visualize millions of high-dimensional data points meaningfully on a single slide. Learning the representation of a network as a whole demonstrates that the topological structure of a network has a predictive power for its growth.

Bio: Qiaozhu Mei is an associate professor at the School of Information, University of Michigan. He is widely interested in data mining, machine learning, information retrieval and their applications to the Web, natural language, social networks, and health informatics.

Machine Learning for Human Decision Making

Abstract: In many real-life settings human judges are making decisions and choosing among many alternatives: Medical doctor deciding a treatment for a patient, criminal court judge making a decision about a defendant, a crowd-worker labeling an image, and a student answering a multiple-choice question. Gaining insights into human decision making is important for determining the quality of individual decisions as well as identifying human mistakes and biases.

In this talk we discuss the question of developing machine learning methodology for estimating the quality of individual judges and obtaining diagnostic insights into how various judges decide on different kinds of items. We develop a series of increasingly powerful hierarchical Bayesian models, which infer latent groups of judges and items with the goal of obtaining insights into the underlying decision process. We apply our framework to a wide range of real-world domains, and demonstrate that our approach can accurately predict judge’s decisions, diagnose types of mistakes judges tend to make, and infer true labels of items.
