Speech Title: Role of Deep Learning and Artificial Intelligence in Clinical Decision Support for Imaging
Abstract: With the advent of new machine learning techniques, the field of automated clinical decision support is poised for a new growth. Previously, the decision support systems have been predominantly rule-based and built on fixed pre-determined associations from clinical knowledge. The IBM AALIM system pioneered a new direction in evidence-based medicine using the concept of patient-data driven learning by exploiting the consensus opinions of other physicians who have looked at similar patients. With the advent of deep learning methods, learning-based decision support can be combined with clinical knowledge-driven techniques to define the next generation of clinical decision support systems.
In this talk, I will discuss the role of deep learning techniques in decision support giving examples in radiology and cardiology imaging. I will also describe the IBM Medical Sieve Radiology Grand Challenge, a worldwide collaborative research effort across IBM research labs that is expanding patient data and knowledge-driven learning to define new clinical decision support systems for radiologists that will one day serve as their cognitive assistants.

Speech Title: Privacy-Preserving Big Data Computing in Clouds

Abstract: With the rapid increase in popularity and variety of big data analytics in cloud environments, privacy disclosure has become a major concern that obstacles the widespread of big data analytics in clouds. Privacy-preserving computing (PPC) has shown to be effective in eliminating this concern. It achieves secure distributed computing on big data in clouds by trading off the utility (accuracy) of the data to be shared (published), either original or final (results). In this talk, I will first address the research challenges of privacy-preserving computing in the cloud computing environment and big data analytics, and then give an overview of the existing work based on data protection techniques and output security levels. I will then introduce our recent work on privacy-preserving statistical and set operations on annoymised and randomized data, structural information protection in hypergraph data publishing, privacy-preserving recommendation, and privacy-preserving clustering. Finally I will conclude the talk by presenting some interesting open problems in privacy-preserving combinatorial optimization currently my team is working on.

NONG YE, Professor
School of Computing, Informatics, and Decision Systems Engineering
Arizona State University, USA

Dr. Ye is a full professor at Arizona State University. Her past and current research has received over $8M external funding support and has produced eighty-five journal papers and five books, including Data Mining: Theories, Algorithms, and Examples. Her recent research focuses on developing data mining algorithms to discover multivariate data associations for capturing both partial-value and full-value variable associations as well as both individual and interactive effects of multiple variables. New algorithms have been applied to cyber attack detection, engineering retention and education, and energy systems modeling.

Speech Title: Learning Partial-Value Variable Associations

Abstract: Existing data analytic techniques are mostly based on building the same one model of variable relations over the full ranges of all variable values, although relations of variables may exist only for certain values of variables or different relations exist for different values of variables. This speech introduces and describes the Partial-Value Association Discovery (PVAD) algorithm which discovers variable relations/associations that exist in partial ranges of variable values from large amounts of data in a computationally efficient way. The PVAD algorithm allows building a structural model of partial- and full-value variable associations in multiple layers that captures individual and interactive effects of multiple variables by learning from data. The applications of the PVAD algorithm to cyber attack detection and engineering retention are also presented

Speech title: Approximation and Sampling in Big Data and Big Learning 

Abstract: In this talk, we cover state of the art sampling techniques in big data and big learning era. One example is to enable both efficient and accurate approximations on arbitrary sub-datasets of a large dataset. Due to the prohibitive storage overhead of caching offline samples for each sub-dataset, existing offline sample based systems provide high accuracy results for only a limited number of sub-datasets, such as the popular ones. On the other hand, current online sample based approximation systems, which generate samples at runtime, do not take into account the uneven storage distribution of a sub-dataset. They work well for uniform distribution of a sub-dataset while suffer low sampling efficiency and poor estimation accuracy on unevenly distributed sub-datasets. 
To address the problem, we develop a distribution aware method called Sapprox. Our idea is to collect the occurrences of a sub-dataset at each logical partition of a dataset (storage distribution) in the distributed system, and make good use of such information to facilitate online sampling. There are three thrusts in Sapprox. First, we develop a probabilistic map to reduce the exponential number of recorded sub-datasets to a linear one. Second, we apply the cluster sampling with unequal probability theory to implement a distribution-aware sampling method for efficient online sub-dataset sampling. Third, we quantitatively derive the optimal sampling unit size in a distributed file system by associating it with approximation costs and accuracy. We have implemented Sapprox into Hadoop ecosystem as an example system and open sourced it on GitHub. Our comprehensive experimental results show that Sapprox can achieve a speedup by up to a factor of 20 over the precise execution.
