Title of lecture: "Practical Hyperparameter Optimization for Deep Learning"
Abstract. While the training parameters of machine learning models are adapted during the training phase, the values of the hyperparameters (or meta-parameters) are specified before the learning phase. For a given dataset, we would like to find the optimal combination of hyperparameter values, in a reasonable amount of time. This is a challenging task because of its computational complexity. We present an integrated view of methods used in hyperparameter optimization of learning systems, with an emphasis on computational complexity aspects. Our thesis is that we should solve a hyperparameter optimization problem using a combination of techniques for: optimization, search space and training time reduction. Case studies from real-world applications illustrate the practical aspects. In previous work, we introduced the Weighted Random Search (WRS) method, a combination of Random Search and probabilistic greedy heuristic. This method outperforms many state-of-the-art hyperparameter optimization methods. We discuss practical applications of WRS in deep learning model optimization.

Title of lecture: "Land of the Giants ... AI Chips" : PDF
Abstract. This presentation will start with a brief historic overview of Artificial Intelligence (AI), explaining the earlier AI waves. Afterwards, the focus of the second part will be on the rapid rise of AI, narrowing it down to Deep Learning, currently perceived as an ubiquitous solution for a wide range of applications. This trend has had, and continues to have, massive financial support and vast substantial implications, which will be mentioned alongside the current “Cambrian explosion” of AI start-ups. The third part will be targeting a sub-class of these AI start-ups, namely those working on designing and building AI chips. These will be classified—into cloud and edge AI hardware—analyzed, and put into context. The fast pace growing number of players in this deceptively esoteric research field will be identified, and their latest results will be surveyed. Finally, we will comment on forthcoming trends of AI hardware while pinpointing its growth potential in the wider context of rebooting and quantum computing seen through larger and larger investments (triggered by the expected demise of Moore’s law).

Title of lecture: "Erratic Extremists Induce Dynamic Consensus: A New Model for Opinion Dynamics" : PDF
Abstract. A society of agents, with ideological positions, or "opinions" expressed as real values ranging from −∞ (the "far left") to +∞ (the "far right"), is considered. At fixed (unit) time intervals agents repeatedly reconsider and change their opinions if and only if they find themselves at the extremes of the range of ideological positions. Extremist agents are erratic: they become either more radical, and move away from the positions of other agents, with probability ε, or more moderate, and move towards the positions held by peers, with probability (1−ε). The change in the opinion of the extremists is one unit on the real line. We prove that the agent positions cluster in time, so that non-extremist agents are eventually located within a unit interval. However, the “consensus opinion” is dynamic. Due to the extremists' erratic behavior the clustered opinion set performs a sluggish random walk on the entire range of possible ideological positions (the real line). The inertia of the group, i.e. the reluctance of the society's agents to change their consensus opinion, increases with the size of the group. The extremists perform biased random walk excursions to the right and left and, in time, their actions succeed to move the society of agents in random directions. The "far left" agent effectively pushes the group consensus toward the right, while the "far right" agent counter-balances the push and causes the consensus to move toward the left. We believe that this model, and some of its variations, has the potential to explain the real world swings in societal ideologies that we see around us. (Joint work with Dmitry Rabinovich)

Title of lecture: "Trends and challenges of cyber-social-technological-cognitive approach in ecosystems" : PDF
Abstract. This lecture aims to provide an international forum to discuss the main ideas about cyber-social-technological-cognitive approach present in indifferent ecosystems. Nowadays, investments that promote disruptive technologies and digital transformation accompanied by advances in Industry 4.0 enable the development of intelligent and smart systems in different domains. The hyperspace allows the interconnection of multiple spaces of computers and networks which are interlinked with each other in cyber, social, technological and cognitive domains.
In the Cyber Domain many digital platforms in the hyperspace collaborate with Internet of the Things (IoT), Internet of Computers (IoC), Internet of the Services (IoS), allowing the integration, interconnection and interaction of people, computers and networks. e-crowd cloud and data bases facilitates the storage media and the interconnections among actors participating in the different interconnected networks. Especially holographic data, semantic sensors, intelligent supervisory control and cooperative actuators all play an important role in dynamic monitoring and decision systems.
In Social Domain it is perceived that many of the social management networks are used by citizens who wish to express their opinion or interact with other people participating in the network. Also, companies or public and private institutions are providing public service and supporting main activities, developing forums and crowd applications to share protocols, knowledge, regulations, ideas, procedures, among other things. In this context legal, cultural, structural, and environmental factors are managed involving companies’ goals and objectives, structure, standards, values for the community, culture and socialization of services.
In Technological Domain Industry 4.0 and digital transformation provides a set of technologies participating in the strategic, business and operational levels. At strategic and business level network technologies such as LAN, WAN, WLAN enable efficient communication and networking in the cyber space for companies and institutions linked. Artificial intelligence (AI) allows the community members display their capabilities, skills, expectations and knowledge, generating heuristics that are mapped in the cyber space as models, methods, techniques, tools and practices. In this way, community learning is shared in the ecosystem. Cybersecurity helps in the transactions, and in the protection of data and information. At operational level automation of physical processes allows real time control of events at operational level activities. Internet of things (IoT) can perceive and sensitize a physical object to be mapped later on the cyber space by technologies such as wireless sensors working at real time, physical data sensors, environmental sensors, equipment and mobile device sensors. Robotics and teleoperation allows acting on fixed and mobile equipment optimizing and making the operation of automated systems more flexible. Drones as aerial vehicles allow a close monitoring of any movements made in a site and its surroundings. Positioning technologies such as passive tags, RFID systems and GPS ensure traceability of products and services, also the transportation media used.
In Cognitive Domain the available knowledge provided by a person, a group, or a community of actors can be stored in the cyber space facilitating the classification and management of social, structural and intellectual capital of each organization participating in the ecosystem. Intellectual capital considers the knowledge of the progress of both intellectual and social capital of the community allowing planning the training needs for different actors.
In this context, we have the opportunity to analyse and discuss trends in some of the main conceptual models and architectures that integrate relevant attributes in hyperspace in different ecosystems, like green energy systems, smart cities, We-Media, among others. In particular, it is important to highlight the role of the Internet of Services (IoS) as it stands out as an ecosystem that takes over complex collaborative applications using interoperable resources across platforms and cloud storage. It also addresses advances in Artificial Intelligence (AI), neuroscience, and cognitive sciences that enable the development of Human Body Communication (HBC) and Human Information Processing (HIP) and thus open the door to multiple applications in the Internet of the People (IoP) domain.

Title of lecture: "Methodologies for Solving Complex Multi-Objective Combinatorial Problems in Engineering: An Evolutionary Approach Applied to Computer Networks" : PDF
Abstract. In real problems in Engineering, solving a problem is not enough; the solution of the problem must be the best solution possible. In other words, it is necessary to find the optimal solution. The solution is the best possible solution because in the real world this problem may have certain constraints by which the solutions found may be feasible, that is, they can be implemented in practice and, unfeasible or that they cannot be implemented. Some of these problems in engineering can be MOP (Multi-Objective Optimization Problem). A general MOP includes a set of n parameters (decision variables), a set of k objective functions and a set of m restrictions. The objective and restriction functions are functions of the decision variables where is possible to obtain a set of optimal values.
Then the MOP can be expressed as:
Optimize y = f(x) = (f1(x), f2(x), ... , fk(x))
Subject to e(x) = (e1(x), e2(x), ... , em(x)) 0
Where x = (x1, x2, ... , xn) X
y = (y1, y2, ... , yk) Y
The method evolutionary algorithm (EA) refers to searching and optimization techniques based on the evolution model proposed by Charles Darwin. Genetic algorithms are used in several areas especially for searching and optimizations. In the real case the algorithm is implemented by choosing a coding for the possible solutions to the problem. The coding is done through chains of bits, numbers or characters that represent the chromosomes. The crossing and mutation operations are applied in a very simple way through functions of vector value manipulation. The EAs are interesting given the fact that at first glance they seem especially apt to deal with the difficulties presented by MOPs. The reason for this is that they can return an entire set of solutions after a simple run and they do not have any other of the limitations of traditional techniques. In addition, some researchers have suggested that the EAs would behave better than other blind searching techniques.

Title of lecture: "Recent advances in data dimensionality reduction using multidimensional scaling" : PDF
Abstract. Human participation plays an essential role in most decisions when analyzing data. The huge storage capacity and computational power of computers cannot replace the human flexibility, perceptual abilities, creativity, and general knowledge. A proper interaction between human and computer is essential. Moreover, such an interaction is one of the areas in computer science that has evolved a lot in recent years. Real data in technologies and sciences are often high-dimensional. So it is very difficult to understand these data and extract patterns. One way of such an understanding is to make a visual insight into the data set. Here, a hopeful view may be put on the visualization of multidimensional data. The goal of visualization methods is to represent the multidimensional data in a low-dimensional space so that certain properties (e.g. clusters, outliers) of the structure of the data set were preserved as faithfully as possible. The dimensionality reduction or visualization methods are recent techniques to discover knowledge hidden in multidimensional data sets. Multidimensional scaling (MDS) is one of the most popular methods for a visual representation of multidimensional data. Low-dimensional visualization requires holding proximities between multidimensional points (observations) as much as possible. MDS requires estimating the coordinates of new points in a lower-dimensional space by minimizing some stress function. The stress function has many local minima often, and iterative algorithms are used for its minimization. Various attempts are made to the global minimum of the stress function still now. Classical approaches to minimize the stress reached their limits. New viewpoint to the problem is necessary, including its formulation and ways of solving. A novel geometric interpretation of the stress function and multidimensional scaling in general (Geometric MDS) has been proposed. Following this interpretation, the step size and direction forward the minimum of the stress function are found analytically for a separate point without reference to the analytical expression of the stress function, numerical evaluation of its derivatives and the linear search. It is proved theoretically that the direction coincides with the steepest descent direction, and the analytically found step size guarantees the decrease of stress in this direction. A strategy of application of the discovered option to minimize the stress function is presented and examined. It is compared with SMACOF version of MDS. The novel geometric approach will allow developing a new class of algorithms to minimize MDS stress, including global optimization and high-performance computing.

Title of lecture: "Consensus in Group Decision Making and Social Networks" : PDF
Abstract. The consensus reaching process is the most important step in a group decision making scenario. This step is most frequently identified as a process consisting of some discussion rounds in which several decision makers, which are involved in the problem, discuss their points of view with the purpose of obtaining the maximum agreement before making the decision. Consensus reaching processes have been well studied and a large number of consensus approaches have been developed. In recent years, the researchers in the field of decision making have shown their interest in social networks since they may be successfully used for modelling communication among decision makers. However, a social network presents some features differentiating it to the classical scenarios in which the consensus reaching processes have been applied. The objective of this talk is to investigate the main consensus methods proposed in social networks and bring out the new challenges that should be faced in this research field.

Title of lecture : "Decision aid, decision advice, decision support: when, why, for whom": PDF
Abstract. We consider complex decision problems which concern difficult situations nd challenges that cannot be adequately represented by simple and traditional decision making models which are based on a straightforward utility maximization, preference analyses, etc. We assume that the complexity of the problem, for instance of strategic planning in a company, calls for an implicit or explicit participation of the humans in the process of conceptualizing, derivation and implementation of decisions which are meant to be not only technically effective and efficient but also to fulfill important more general goals, notably social. For this purpose we will use some solutions advocated in the broadly perceived human centric systems, human-in/on/ot-the loop, etc. Moreover, we will employ the concept of a decision making process that involves more factors and aspects like: the use of own and external knowledge, involvement of various „actors”, aspects, etc., individual habitual domains, non-trivial rationality, different paradigms, etc. In general, we assume that we have a „client”, who may be exemplified by a business owner or manager, and who needs a help in solving his or her problems from an „analyst” who can be a human domain specialist, exemplified by an operations research expert, or an artificial, computer based system, exemplified by an advice giving system (recommender) or a decision support system. We assume that the client has a limited knowledge of formal and algorithmic tools and techniques, and needs an easy to use solution. On the one extreme, we assume that we can have a relatively effective and efficient model for solving it, for instance from a multiple criteria decision making class, and the client involved can provide us with some additional information or data so that we can use the paradigm of decision aid. On the other extreme, we assume two possible situations that, first, the model is practically unavailable but we have either domain knowledge, mostly tacit but maybe even to some extent explicit, or – second – we have enough data to pursue the so called data driven modeling. In both case we resort to the use of some non-model-driven decision suport systems. We also advocate that in some difficult situations in which specifics of a particular customer can be relevant, the paradigm of a decision advice can be employed using some new ideas from recommenders, notably their recent versions which can also provide reasons, rationale and explanations for a particular advice.
