Description: Our time could be defined as the age of Data. With the availability of large amount of data and massive computational resources, the main challenge before data scientists is to get insightful information from the data. Naturally, AI (Artificial Intelligence) and ML (Machine Learning) are two main vehicles in getting the insights. The main type of recently available data is indeed a new, modern and unprecedented form of data. “Modern Data” has unique characteristics such as, extreme sparsity, high correlation, high dimensionality and massive size. Modern data is very prevalent in all different areas of science such as Medicine, Environment, Finance, Marketing, Vision, Imaging, Text, Web, etc.
A major difficulty in dealing with modern data is that many of the old methods that have been developed for analyzing data during the last decades cannot be applied directly to modern data. One major solution, to overcome this challenge, is to effectively use ensemble methods such as deep artificial neural networks. These types of ensemble models are heavily reliant on the deployment of efficient computational methods. Thus, it’s even more imperative to deploy faster, more accurate and robust computational techniques for AI and ML models.
This track covers the application of computational methods for Artificial Intelligence and Machine Learning models.

Description: The majority of humans today live in complex societies, which exist on the basis of extensive cooperation among large numbers of individuals. Recent studies in sociology have focussed on interconnectivity in social relationships and the emergence of new properties within society. As a theoretical tool, social complexity theory serves as a basis for the emergence of macro-level (or Meso level) social phenomena, providing a theoretical platform for hypothesis formation.
The aim of the workshop is to stimulate interdisciplinary research and cooperation to develop complex systems-based approaches aimed at understanding social systems. In general, the workshop will focus on the following questions: What are the patterns in social systems that cannot be explained by the existing theories and data? What kinds of data are needed to better inform the models? What new modeling techniques and methods need to be developed?
One of the immediate outputs of the workshop will be the publication of a special issue in a scientific journal to be determined.
Broad topics in social complexity:

1. Modeling social phenomena such as (but not limited to) – population dynamics, migration patterns, armed conflicts, political movements, natural disasters, etc – and the many possible arrangements of relationships between these discrete phenomena.
2. Modeling for sustainable development goals (poverty, well-being, food security, water, energy, etc.) in rapidly growing urban complex societies. Focusing on the role of modeling in policy and urban planning.
3. Modeling individual and group behavior. New modeling techniques in computational social science.
4. Emergent phenomena of complex social systems: self-organization, regime shifts, tipping points, and resilience.
5. Empirical calibration and validation of computational models for complex social systems.
6. Novel (curated) datasets for understanding complex social systems. The Social Complexity of Digital Data (new metatheory, complex realism in social research).
7. Computational analysis of complex social systems, e.g., network analysis, social media, big data, etc.

Description: Information analysis is nowadays crucial for societies, single citizens in their everyday life (e.g. while travelling, shopping, browsing, communication etc.) as well for businesses and overall economy. The right to be informed is one of fundamental requirements allowing for taking right decisions in a small and large scale (e.g. elections).
However information spreading can be also used for disinformation. The problem of the fake news publication is not new and it already has been reported in ancient ages, but it has started having a huge impact especially on social media users or people watching media news (Internet, newspapers, tv etc.). Such false information should be detected as soon as possible to avoid its negative influence on the readers and in some cases on their decisions.
Another problem and emerging challenge is coming from using automated information analysis and decision support systems (based on Artificial Intelligence (AI) and Machine Learning (ML) advances) as black-box single truth providers. If those information analysis systems are misused, attacked or fooled, their results will also lead to (dis-) information.
The main aim of this workshop is to bring together researchers and scientists computational science who are pioneering (dis-)information analysis methods to discuss problems and solutions in this area, to identify new issues, and to shape future directions for research. Moreover, we invite prospective researchers to send papers concerning (dis-)information detection methods and architectures, explainability of information processing methods and decision support systems as well as their security.
The list of possible topics includes, but is not limited to:

• computational methods for (dis-) information analysis, especially in heterogenous types of data (images, text, tweets etc.)
• detection of fake news detection in social media
• deepfakes analysis
• images and video manipulation recognition
• architectural frameworks and design for (dis-)information detection
• aspects of explainability of information analysis systems and methods (including explainability of ML)
• adversarial attacks on information analysis
• explainability of deep learning
• learning how to detect the fake news in the presence of concept drift
• learning how to detect the fake news with limited ground truth access and on the basis of limited data sets, including one-shot learning
• proposing how to compare and benchmark the fake news detectors
• case studies and real-world applications
• human rights, legal and societal aspects of (dis-)information detection, including data protection and GDPR in practice

The session will be supported by by SocialTruth project (Socialtruth.eu), which has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No. 825477 and will be technically endorsed by IEEE SMC TC on Big Data Computing.

Description: The agricultural sector is facing enormous challenges to increase food production despite limited availability of arable lands, the increasing need for fresh water and the impact of climate change. In a rapidly changing world, natural resources, such as land, water, soil and genetic resources, must be better managed so that more productive and resilient agriculture can be achieved. This workshop is focussed on analytic tools and decision support systems that help to guide actions needed to transform and reorient agricultural systems.
Topics include, but are not limited to:

• Optimisation in agro-ecosystems
• Intelligent irrigation systems
• Integrated sensing technology
• Precision agriculture methods
• Agriculture decision support systems

The area presents significant and challenging difficulties in developing robust predictive tools subject to uncertainties in climate and ecosystem responses, with recommendations needed that are relevant, productive and accurate over multiple decades. Furthermore, expertise in agronomy and economic factors needs to be integrated with modelling and simulation to allow analysis of “whole system” dynamics. Current research efforts are proceeding in algorithm development and innovative computational methods to solve these problems, and deliver outcomes. In the context of an interconnected world – the research has the potential to contribute to climate change adaptation and food security in a global context. Research and tools are needed for decision support for policy responses at a range of levels of responsibility: individual, regional, national and international.

Description: In the late 1960’s, simple data assimilation revolutionarily transformed science in fields based on satellite data. Both NASA and NCAR produced stunningly revolutionary applications. The oil and gas industry jumped on this concept in the early to mid 1970’s creating commercial data assimilation pipeline products by multiple vendors that were used in more than 165 countries in short order. This led to intelligent data assimilation being the normal way to operate a reservoir or pipeline networks by the 1990’s by all of the major oil producers. Since the early 2000’s, government grant agencies (e.g., the National Science Foundation) applied this concept to update numerous fields creating astonishing improvemnts in simulations that continue to this day in many application areas.
A data-driven computational system is the integration of a simulation with dynamically and intelligently assimilated data, multiscale modeling, computation, and a two way interaction between the model execution and the data acquisition methods (see the DDDAS Scientific Community Web Site, http://www.dddas.org). The workshop will present opportunities as well as challenges and approaches in technology needed to enable Data-Driven Computational Science capabilities in applications, relevant algorithms, and software systems. All related areas in Data-Driven Sciences are included in this workshop, including CyberPhysical Systems like HealthKit on iPhones and iPads as well as similar systems developed by Intel, Google, and Microsoft for phones and tablets, Internet of Things (IoT), Cloud of Things (CoT), and Data Intensive Scientific Discovery (DISD).
A recent example is a tranformative way of landing airplanes on time and reduce delays and cancellations is a process known as Time Based Flow Systems (TBFS) [UKNATS]. It spaces planes by space instead of by time. The first of these systems was developed for Heathrow Airport by Lockheed Martin for the British National Air Traffic Services and fully deployed in May, 2015. It has reduced flight cancellations due to wind by exactly 100% and flight delays by approximately 40% during the period of May – August, 2015.

Description: The object of the theory of dynamical systems addresses the qualitative behaviour of dynamical systems as understood from models. Moreover, models are often not perfect and can be improved using data using tools from the field of Data Assimilation. Additionally, the field of Machine Learning is concerned with algorithms designed to accomplish certain tasks whose performance improve with the input of more data.
The intersection of the fields data assimilation, machine learning and dynamical systems is largely unexplored, and the goal of the MLDADS workshop is to bring together contributions from these fields to fill the gap between these theories in the following directions:
(1) Machine Learning for Data Assimilation: how to assist or replace the traditional methods in making forecasts, without the unrealistic assumption (particularly linearity, normality and zero error covariance) of the conventional methods.
(2) Machine Learning for Dynamical Systems: how to analyze dynamical systems on the basis of observed data rather than attempt to study them analytically.
(3) Data Assimilation for Machine Learning and/or Dynamical Systems: how well does the model under consideration (Machine Learning model and/or Dynamical System) represent the physical phenomena.(4) Data Assimilation and Machine Learning for Dynamical Systems: how can tools from the interaction between the theories of Data Assimilation and Machine Learning be used to improve the accuracy of the prediction of dynamical systems.

Description: Meshfree methods are a hot topic in computational sciences and numerical mathematics. Standard computational methods used across many application fields require tessellation in 2D or 3D using triangular or tetrahedral meshes. Tessellation itself is computationally expensive especially in higher dimensions and the result of that computation is again discrete, and physical phenomena are not smoothly interpolated.
The meshfree methods are especially convenient for scattered data processing as they do not require tessellation. They are used not only for interpolation and approximation, but also for a solution of partial and ordinary differential equations, etc. Meshfree methods are scalable to higher dimensions and offer smooth final representation and they lead to a solution of a system of linear equations, in general.
This ICCS 2021 workshop is intended to explore broad computational applicability of the Meshfree methods especially based on Radial Basis Functions across many areas, including theoretical and mathematical aspects of the Meshfree methods.
The aim is also to connect latest theoretical research results with possible computational applications, i.e. put together theory and applications in computational sciences.
Main topics (but not limited to):

• Meshfree methods in engineering problems
• Meshfree methods and differential equations
• Meshfree methods and GIS, CAD/CAM systems
• Meshfree methods in theory and practice
• Meshfree methods and computational and numerical issues
• Meshfree interpolation and approximation methods for large scalar and vector data sets

Description: Modelling and simulation of multiscale systems constitutes a grand challenge in computational science, and is widely applied in fields ranging from the physical sciences and engineering to the life science and the socio-economic domain. Most of the real-life systems encompass interactions within and between a wide range of spatio-temporal scales, and/or on many separate levels of organization. They require the development of sophisticated models and computational techniques to accurately simulate the diversity and complexity of multiscale problems, and to effectively capture the wide range of relevant phenomena within these simulations. Additionally, these multiscale models frequently need large scale computing capabilities as well as dedicated software and services that enable the exploitation of existing and evolving computational ecosystems.
The multiscale modelling and simulation (MMS) workshop aims to provide a forum for multiscale application modellers, framework developers and experts from the distributed infrastructure communities to identify and discuss challenges in, and possible solutions for, modelling and simulating multiscale systems, as well as their execution on advanced computational resources and their validation against experimental data.

Description: Modeling of flow and transport is an essential component of many scientific and engineering applications, with increased interests in recent years. Application areas vary widely, and include groundwater contamination, carbon sequestration, air pollution, petroleum exploration and recovery, weather prediction, drug delivery, material design, chemical separation processes, biological processes, and many others. However, accurate mathematical and numerical simulation of flow and transport remains a challenging topic from many aspects of physical modeling, numerical analysis and scientific computation. Mathematical models are usually expressed via nonlinear systems of partial differential equations, with possibly rough and discontinuous coefficients, whose solutions are often singular and discontinuous. An important step of a numerical solution procedure is to apply advanced discretization methods (e.g. finite elements, finite volumes, and finite differences) to the governing equations. Local mass conservation and compatibility of numerical schemes are often necessary to obtain physical meaningful solutions. Another important solution step is the design of fast and accurate solvers for the large-scale linear and nonlinear algebraic equation systems that result from discretization. Solution techniques of interest include multiscale algorithms, mesh adaptation, parallel algorithms and implementation, efficient splitting or decomposition schemes, and others.
The international workshop on “Simulations of Flow and Transport: Modeling, Algorithms and Computation” (SOFTMAC) has been held 9 years since 2011 within the International Conference on Computational Science (ICCS). The aim of this special issue is to bring together researchers in the aforementioned field to highlight the current developments both in theory and methods, to exchange the latest research ideas, and to promote further collaborations in the community. We invite original research articles as well as review articles describing the recent advances in mathematical modeling, computer simulation, numerical analysis, and other computational aspects of flow and transport phenomena of flow and transport. Potential topics include, but are not limited to:

• advanced numerical methods for the simulation of subsurface and surface flow and transport, and associated aspects such as discretization, gridding, upscaling, multiscale algorithms, optimization, data assimilation, uncertainty assessment, and high performance parallel and grid computing;
• spatial discretization schemes based on advanced finite element, finite volume, and finite different methods; schemes that preserve local mass conservation (such as mixed finite element methods and discontinuous Galerkin methods) are of particular interest;
• decomposition methods for improved efficiency and accuracy in treating flow and transport problems; decomposition methods for nonlinear differential equations and dynamical systems arising in flow and transport; temporal discretization schemes for flow and transport;
• a-priori and a-posteriori error estimates in discretizations and decompositions; numerical convergence study; adaptive algorithms and implementation;
• modeling and simulation of single-phase and multi-phase flow in porous media or in free space, and its applications to earth sciences and engineering;
• modeling and simulation of subsurface and surface transport and geochemistry, and its application to environmental sciences and engineering;
• computational thermodynamics of fluids, especially hydrocarbon and other oil reservoir fluids, and its interaction with flow and transport;
• computational modeling of flow and transport in other fields, such as geological flow/transport in crust and mantle, material flow in supply chain networks, separation processes in chemical engineering, information flow, biotransport, and intracellular protein trafficking, will also be considered.

Description: This is a time of great growth at the intersection of software engineering and computational science, increasingly manifested in the emerging discipline of Research Software. There is a need for members of these communities to share experiences, identify problems, and enumerate common goals to form the basis for an ongoing research agenda. The goal of this workshop is to provide a unique venue for the presentation of results and to facilitate interaction between software engineers and computational scientists. To address this goal, we seek contributions from members of both communities that describe perspectives, research outcomes, and lessons learned (positive or negative) from the development of computational science software.
Specifically, we are interested in the software development and software engineering challenges and enablers relating to: (1) Computational science software applications solve complex software- or data-intensive research problems. These applications range from large parallel models/simulations of the physical world using HPC systems to smaller scale simulations developed by a single scientist or engineer on a desktop machine or a small cluster. (2) Applications domains ranging from humanities to engineering to science. (3) Applications that support scientific research and experiments at scale. Such applications include, but are not limited to, systems for managing and/or manipulating large amounts of data and systems that provide infrastructure for scientific or engineering applications such as libraries or HPC/Cloud software. (4) The process for building, reusing, and publishing software and data used in scientific experiments or engineering innovations. Among others, these processes include agile approaches, open source/open data issues, testing scientific software, and managing software or data repositories for publishing goals.
This workshop will build upon previous SE4Science workshops. Similar to the format of the previous workshops, in addition to presentation and discussion of the accepted papers, we plan to devote significant time during the workshop to discussing important topics that arise from the paper presentations. The goal of these discussions is to (1) develop a joint research plan that can be conducted collectively by workshop participants and (2) development of ideas/draft of position statements to be published externally.

Description: Problems with uncertainty need to be tackled in an increasing variety of areas, from physics, chemistry, engineering, computational biology and environmental sciences to decision making in economics and social sciences. Uncertainty is unavoidable in almost all systems analysis, risk analysis, decision making and modelling and simulation. How uncertainty is handled and quantified shapes the integrity of the analysis, and the correctness and credibility of the solution and the results.
With the advent of exascale computing, big data analytics and scalable AI, larger and larger problems – often requiring hybrid approaches – have to be tackled in a systematic way at scale. The variety of methods and approaches of solving such problems with uncertainties and quantifying the uncertainties become even more important due to the variety and scale of uncertainties in such problems.
The focus of the workshop will be on methods and algorithms for solving problems with uncertainties, stochastic methods and algorithms for solving problems with uncertainties, methods and algorithms for quantifying uncertainties such as dealing with data input and missing data, sensitivity analysis (local and global), dealing with model inadequacy, model validation and averaging, software fault-tolerance and resilience and more.

Description: Given that uncertainty is unavoidable in almost all scientific fields, due to e.g. unknown parameters or simplifying modelling assumptions, uncertainty quantification is an indispensable part in state-of-the-art computational models. In order to build confidence in their results, it is therefore crucial that these models carry their own measure of uncertainty, especially when they are extrapolated beyond the domain in which they were originally calibrated. Also, the oncoming Exascale Computing resources will open up the possibility of solving problems with increased complexity and computational burden, exacerbating the importance (and demands) of reliable uncertainty quantification methods. This thematic track aims to attract research that focuses on new methods, which outperform existing techniques, as well as uncertainty quantification applications to complex problems. Topics of interest include but are not limited to the following:

• Forward and inverse uncertainty quantification;
• Model inadequancy;
• Sensitivity analysis;
• Dimension reduction;
• Surrogate modelling (including machine-learning techniques and reduced-order modelling);
• Case studies showing efficient uncertainty quantification methods;
• Software for uncertainty quantification.
