Prof. Věra Kůrková received Ph.D. in topology from Charles University, Prague in 1980 and DrSc (equiv. Prof.) in 1999. Since 1990, she has been a scientist with the Institute of Computer Science, Czech Academy of Sciences. From 2002 to 2008, she was the Head of the Department of Theoretical Computer Science. Her research interests include machine learning, mathematical theory of neurocomputing, inverse problems, nonlinear approximation and optimization. She is an associate editor of the journals Neural Networks, Neural Processing Letters, and in 2008-€“2009 also of IEEE Transactions on Neural Networks. She is the president  the European Neural Networks Society and was the general Chair of conferences ICANNGA 2001 and ICANN 2008. In 2010 she was awarded by the Czech Academy of Sciences the Bolzano Medal for her contributions to mathematics.

Title: Capabilities of Shallow and Deep Networks
Abstract: Although originally biologically inspired neural networks were introduced as multilayer computational models, later shallow architectures (with one hidden layer of computational units) became dominant in applications. Recently, interest in architectures with several layers was revived due to successes of deep convolutional networks. Experimental evidence motivated theoretical research aiming to characterize tasks for which deep networks are more suitable than shallow ones. This lecture will present recent theoretical results comparing capabilities of shallow and deep networks. In particular, it will focus on complexity requirements of shallow and deep networks performing high-dimensional tasks. Connections with the No Free Lunch Theorem, the central paradox of coding theory, and pseudo-noise sequences will be discussed.

Prof. Debjani Chakraborty has been a faculty member of Indian Institute of Technology, Kharagpur since 1997 in School of Management and Department of Mathematics respectively. Dr. Chakraborty received B.Sc. (Mathematics Hons.) in 1987 from University of Calcutta and M.Sc. (1989), Ph.D. (1995) from IIT Kharagpur with CSIR fellowship. She is the recipient of the prestigious Young Scientist Award 1997 in Mathematics from Indian Science Congress Association for her contributions to multi-objective optimization in imprecise and uncertain environment. She has also been awarded the Young Scientist Scheme from Dept. of Science & Technology, Govt. of India in 1997 as an individual scientist. She is a nominated member of the Indian National Science Academy of Science, Allahabad. Her current areas of research include theory and applications of fuzzy logic in optimization, fuzzy geometry, and fuzzy logic in medical science and technology. She has authored more than 120 papers among which more than 70 are in peer-reviewed journals. She has also delivered e-learning through online web and video lecture series on Optimization under NPTEL and MOOC programmes.

rosana

Prof. Rosana Rodríguez-López completed her studies of the bachelor’s degree in Mathematics in 1998 at the University of Santiago de Compostela, Spain, and obtained the Ph.D. degree in Mathematics at the same university in 2005. She is working at the Department of Statistics, Mathematical Analysis and Optimization (Area of Mathematical Analysis), University of Santiago de Compostela (USC), where she is a member of the research group on Nonlinear Differential Equations.
From 2013 to 2016, she was the head of the Department of Mathematical Analysis at USC,  and currently she is the vice dean of the Faculty of Mathematics at this university.
She is author or coauthor of more than 60 papers, several of them on the topic of fuzzy differential equations and published in journals such as Information Sciences or Fuzzy Sets and Systems, and has participated in several conferences in this field.
She has been involved in activities about divulgation of Mathematics for high school students, and is part of the team of founders of CorBi Foundation, whose main aim is to apply mathematics and computation to biomedical problems, neurosciences, etc.

Title: On some properties of the solutions to fuzzy differential equations
Abstract: Fuzzy differential equations can be considered an adequate approach to model phenomena subject to uncertainty. However, the properties of the solutions to this type of equations are strongly related to the method followed to define the notion of solution itself. Several approaches are possible, some of them based on different concepts of derivatives for fuzzy-valued functions (Hukuhara, strongly generalized, or generalized Hukuhara differentiability) and other independent of them.

We present some properties of the solutions (in some simple cases, the explicit expressions) using different approaches, and explore some methods for the existence of solutions satisfying certain conditions, highlighting the differences with respect to the classical case.
