DEA under Big Data: Data Enabled Analytics and Network Data Envelopment Analysis
Prof. Joe Zhu
Worcester Polytechnic Institute, USA
Abstract
This talk proposes that data envelopment analysis (DEA) should be viewed as a method (or tool) for data-oriented analytics in performance evaluation and benchmarking. While computational algorithms have been developed to deal with large volume of data (decision making units, inputs, and outputs) under the conventional DEA, valuable information hidden in big data that are represented by network structures should be extracted by DEA. These network structures, e.g., transportation and logistics systems, encompass a broader range of inter-linked metrics that cannot be modelled by the conventional DEA. It is proposed that network DEA is related to the value dimension of big data. It is shown that network DEA is different from the standard DEA, although it bears the name of DEA and some similarity with the conventional DEA. Network DEA is big Data Enabled Analytics (big DEA) when multiple (performance) metrics or attributes are linked through network structures. These network structures are too large or complex to be dealt with by the conventional DEA. Unlike the conventional DEA that are solved via linear programming, general network DEA corresponds to nonconvex optimization problems. This represents opportunities for developing techniques for solving non-linear network DEA models. Areas such as transportation and logistics system as well as supply chains have a great potential to use network DEA in big data modeling.

Keynote 2:
Modern Sliding Mode Control with Application to Connected and Automated Vehicles
Prof. Antonella Ferrara
(IEEE Fellow)
University of Pavia, Italy
Abstract
Sliding Mode Control is a nonlinear control methodology based on the use of a discontinuous control input which forces the controlled system to switch from one structure to another, evolving as a variable structure system. This structure variation makes the system state reach in a finite time a pre-specified subspace of the system state space where the desired dynamical properties are assigned to the controlled system. In the past years, an extensive literature has been devoted to the developments of Sliding Mode Control theory. This kind of methodology offers a number of benefits, the major of which is its robustness versus a significant class of uncertaintiesduring the sliding mode. Yet, it presents a crucial drawback, the so-called chattering, which may disrupt or damage the actuators and induce unacceptable vibrations throughout the controlled system. This limits the practical applicability of the methodology, especially in case of mechanical or electromechanical plants. This drawback has been faced by the theoretical developments of the last two decades. They will be reviewed in this talk, illustrating how the “modern” results can beprofitably used to solve practical control problems in complex systems as the automotive ones. The talk will develop starting from single vehicle control and coming to discuss formation control of fleets of connected and automated vehicles (CAVs), with the aim of producing a beneficial impact on road traffic..

Deepening Smart Data: Quality data to enhancing Deep Learning applications
Prof. Francisco Herrera
University of Granada, Spain
Abstract
In the last years, deep learning methods and particularly Convolutional Neural Networks (CNNs) have exhibited excellent accuracies in many image and pattern classification problems, among others.
The strengthening smart data to get quality datais the foundation for good data analytics in general. It is very important for getting a good deep learning model from an applied point of view. Consolidating smart data requires a data preprocessing analysis to adapt the raw data to fulfill the input demands of each learning algorithm.
In contrast to the classical classification models, the high abstraction capacity of CNNs allows them to work on the original high dimensional space, which reduces the need for manually preparing the input. However, a suitable data preprocessing is still important to improve the quality of the model.One of the most used preprocessing techniques with CNNs is data augmentation for small image data sets, which increases the volume of the training data set by applying several transformations to the original input. There are other data guided preprocessing procedures for specific problems, like image brightness or contrast, noise adaptation, among others.
In this talk we present the connection between deepening smart data and heightening deep learning, focused on some applications enhancing. Among them, we will present some video surveillance applications and the best result in the MNIST problem with only 10 errors.

Privacy and safety in cyber-physical systems
Prof. Dimitri Lefebvre
University of Le Havre Normandie, France
Abstract
In recent years, the tremendous growth of computer technology has led to the proliferation of highly complex cyber-physical systems, in particular in Industry 4.0 and Internet of Things. Such systems exhibit behaviors determined by the asynchronous occurrence of certain events and are termed Discrete Event Systems(DES). Examples of DES are encountered in many traditional application domains, such as automated manufacturing, computer networks, transportation, as well as in emerging areas like healthcare, or management of technical, human and financial resources.
A significant research effort has been devoted to DES in order to address a series of difficult problems that are often combinatorial in nature, and require advances methodologies The aim of this talk is first to give some basic modeling notions to represent DES in order to address a large variety of problems for cyber-physical systems. Then, some privacy,and safety issues are discussed. On one hand, opacity is presented to increase privacy and cyber-security. On the other hand, fault diagnosis illustrates how it is possible to detect and isolate some faults in the system based on its observations. Performance evaluation is introduced to provide a detailed analysis of such properties.
Finally, a list of open questions and future challenges is proposed.
