Title of talk: How Self-Organizing Maps Empower Convolutional Neural Networks

Abstract: One of the main challenges in representation learning is to deal with high-dimensional, unstructured data for classification, where the inherent complex relationship among points can be understood toward a representation into a significantly lower dimension, viz Euclidean spaces. The challenge becomes more prevalent when dealing with various types of heterogeneous data. This talk discusses a systematic, generalized method that uses self-organizing maps (SOMs) to represent higher dimensions onto a two- dimensional grid. Afterwards, a convolutional neural network (CNN) is applied to predict or classify samples such as documents or disease states of various types. Integration of multi-omics data for prediction of cancer subtypes and detection of biomarkers will be discussed. In addition, the talk will show the use of information about semantically- similar words around mapped via a SOM, followed by prediction of spam reviews via a CNN.

Title of talk: Closed vs Open Systems

Abstract: The marketing of computing systems in the early days included the bundling of basic software support. This included the operating system, the compilers and libraries as well as training manuals. This model was subjected to a monopoly What has happened now is that closed systems are marketed today that have the software, including privacy compromising bugs and tracking sub-systems, built into them. All the software applications created by independent software houses are installed via the operating system of the closed system and the device maker imposes a percent charge. There is no move anywhere to un-bundle software, including the applications and the hardware. In this talk, we will examine the philosophy of moving away from such closed systems to improve innovation and hence create better systems.

Title of Talk: Data Analysis using Bayesian Networks

Abstract:  Bayesian networks are widely used as a data analysis tool in diverse areas, including finance, medicine, and sports. In this talk, I will review Bayesian networks and discuss their use and advantages for data analysis. I will then focus on our recent work on learning the graphical structure of a Bayesian network from discrete data based on learning *all* near-optimal networks. Our approach allows us to identify features such as edges between variables with high confidence and has led to improved data analysis algorithms both in terms of accuracy and scale. The talk will be aimed at a general audience.

Title of Talk: Error-Resilient Collaborative Intelligence

Abstract: Edge-cloud Collaborative Intelligence (CI) is a framework in which AI models are distributed between the edge devices and the cloud. Typically, the front-end of an AI model is deployed on an edge device, where it performs initial processing and feature computation. These intermediate features are sent to the cloud, where the back-end of the AI model completes the inference. CI has been shown to have the potential for energy and latency savings compared to the more typical cloud-based or fully edge-based AI model deployment. However, new challenges arise from the fact that there is now an error-prone channel in the information pathway of the distributed AI model. The focus of this talk is error resilience in CI systems. I will describe certain properties of intermediate features from deep neural networks that make error-resilient CI possible. I will also present an overview of recent work on tensor completion for recovery of missing data in packet-based transmission of deep feature tensors, along with promising avenues for future work.

Title of Talk: Data Visualization for Empowerment and Inclusion

Abstract: In this talk I touch on a few moments in my research history that have changed my way of thinking and gradually leading me to become passionate about – data visualization for empowerment and inclusion. I have chosen moments that are memorable to me because they have changed the way I think. I will step through my process of discovering the importance of thinking about how to make visualizations more empowering, more engaging, and more expressive, and how may lead to developing visualizations that work better for us as externalizations. I will relate these points to discussions and data feudalism and the importance of us staying connected to our data heritage.

Title of Talk: Challenges in Building Grass Roots Wireless Sensor Networks

Abstract: We will describe our experiences over the last two decades with building real systems of wireless sensors using off-the-shelf, and generally inexpensive, components. Even today, with a diverse set of sensor offerings and protocols, one does not always find a good fit for particular applications. Rethinking an application from the wireless sensor network point of view usually involves considerations related to: a) energy supply limitations, b) data transfer limitations, and c) protocol flexibility.  At the same time, any solution has to fit within the meagre resources of a, generally, low end computational platform.  For energy considerations, we will present protocol-level mechanisms and energy harvesting strategies. For data transfer limitations, we will outline the potential benefit of in-network processing, namely as various forms of data aggregation.  Finally, for protocol flexibility, we will introduce an expressive rule-based cross-layer forwarding rule system, that captures a vast set of low-level protocol mechanisms while being resource conscious.

Title of Talk: Digitalization of Software Development via Virtual Reality

Abstract: In the new age of information technology, enterprises are following the trend of digital transformation to foster innovations by converting their operation models. While software product line engineering (SPLE) promises huge increase of productivity by means of mass production, the lack of support for interactive software customization has become one of the major obstacles that slows down advancements in software industry. This talk will first highlight the benefits of SPLE for developing a diversity of similar systems and then discuss the ability of VR for creating digital counterparts of real-word entities before exploring the potentials of digitalizing software development by allowing the virtual representation of software developers to assist software clients “ordering” software products online according to their need.

Title of Talk:  Storage Systems for the Edge

Abstract: The advent of the Internet of Things (IoT) has led to a large amount of generated data, new requirements for real-time processing, and the proliferation of distributed heterogeneous computing resources. In emerging scenarios, such as Smart Cities and Industry 4.0, files, videos, and pictures are produced by sensors on the edges of the Internet.  Transporting this data over Internet links to cloud data centers for processing and storage places several bandwidth requirements on the network and is not compatible with applications that require low latency. Edge computing has emerged as an alternative approach that leverages small regional data centers, from a few computers to a few racks, at the Internet edges to carry out processing tasks and store data. This proximity to the location of data generation enables new systems that provide low latency and reduce network load.  In this talk, I will describe recent research on distributed storage systems designed to simplify the deployment of novel applications on a hierarchy of data centers that span from the edge of the network for the wide-area cloud.
