Positions for PostDoctoral FellowsThe Alberta Innovates Centre for Machine Learning is looking to hire strong researchers as postdoctoral fellows (PDFs), for various projects, both application pull and technology push; see also the 1page ad (PNG PDF); this page is http://webdocs.cs.ualberta.ca/~rgreiner/index1.php?section=PostDoc15If you are interested in any of the positions mentioned below (note the Other category), please email ...
Use 'PDF Medical Informatics' as the subject of your email. While we have funding for some of these positions, it is always helpful if you have funding to bring in (part of) your salary from some external sources (eg, a PostDoctoral Fellowship).

Proteome AnalystThe Proteome Analyst system can analyse a set of peptide sequences (proteins) in a given proteome and return the general function, and subcellular location, of each protein, as well as a functional summary for the entire proteome. The current version first maps each novel protein to a set of attributes -- namely the tokens that appear in certain fields of the (known proteins) homologs found by Blast -- then finds the general function (resp., subcellular location) most associated with this token-set, based on a learned classifier. We are looking for a researcher (summer student, grad student, postdoctoral fellow) to help us extend Protein Analysis in several ways:
Project Webpage Budgeted LearningLearning tasks typically begin with a data sample --- eg, symptoms and test results for a set of patients, together with their clinical outcomes. By contrast, many real-world studies begin with no actual data, but instead with a budget --- funds that can be used to collect the relevant information. For example, one study has allocated $30 thousand to develop a system to diagnose cancer, based on a battery of patient tests, each with its own (known) costs and (unknown) discriminative powers. Given our goal of identifying the most accurate classifier, what is the best way to spend the $30 thousand? Should we indiscriminately run every test on every patient, until exhausting the budget? Or, should we selectively, and dynamically, determine which tests to run on which patients? We call this task budgeted learning. There are many open questions, both theoretic and empirical.
Learning and Validating Belief NetsBayesian belief nets (BN) are becoming the preferred tool for a wide variety of tasks, ranging from sensor fusion to information retrieval. We are currently developing and experimenting with various tools for learning these BNs from training data. We are looking for a student to help us here, both in developing and implementing these learning system, and also in running careful experiments to help us compare these different approaches. We also plan to investigate ways to learn, and use, Probabilistic Relational Models --- extension to belief nets that allow the representation of relationships. We will also explore ways to compute and use "variance" around the belief net response; see webpage: extending the work on "mixture using variance" and perhaps a variance-based model of value-of-information.
OtherWe are always open to ideas, especially ones that are motivated by medical tasks... perhaps related to Patient-Specific Survival Prediction ... or covariate shift? ... or "large p, small n"? ...) Here, you need to motivate the task, by explaining why it is relevant to some real (medical?) problem, and why it involves good science to solve! |
