    • Abstract
      In this tutorial, we will discuss - how we can trust AI models? Put simply, we trust things which behave as we expect them to. We will discuss four key requirements - bias, lineage, explainability and robustness, which go a long way towards trusting an AI model and understanding their behavior. We will discuss few AI trust and governance use-cases and how these use-cases inter-relate with bias, explainability, lineage and robustness requirements. We will provide a brief overview of the research efforts in these four domains and outline some research problems in this space. At IBM, we have been working on building a trusted AI platform and we will also discuss some insights from our experience.

    • Abstract
      The unexpected win of Trump at least has proven one fact that social computing --- personality, values, ethnicity, gender, political view analysis from social media content have immense power and it can change the shape of the world! Facebook and the data analytics company called Cambridge Analytica are at the center of a dispute over the harvesting and use of personal data. The question comes - what to learn from the history? Social Science is on the verge of a paradigm shift that allows us to ask and answer questions that were unthinkable a few decades ago. We can now collect data about human behavior on a scale never before possible and with tremendous granularity and precision, but as always said - great power comes with great responsibility.
      Therefore, Social Computing has been emerging as an independent research problem. Social Computing, mostly deals with a data-driven understanding of complex social networks, which often requires knowledge about graph analysis, data mining, natural language processing, and machine learning. Therefore, this tutorial is formed around five major topics that all fall under the emerging field of computational social science: Psychology and Sociology, Natural Language Processing, Complex Network, Big Data, and Machine Learning and how to use them together to answer few buzzing questions of our times.

    • Abstract
      Widespread use of spatial computing technologies has lead to increasing interest in mining interesting and non-trivial patterns from spatial data. Over the years several works have made progress towards this end by exploring different aspects of the problem of finding patterns from data which is embedded in a geographic space. This talk would focus on one particular pattern family called the spatial co-location patterns which have gained widespread attention due to their potential uses. The talk would cover well known algorithms for mining spatial co-location patterns from large dataset in a time-efficient manner. We would also cover some of the new directions of research being explored in this area.

    • Abstract
      Several key transformations in the macro-environment coupled with recent advances in technology have opened up tremendous opportunities for innovation in the financial services industry. We discuss the implications and ramifications of these macro-environmental trends for data science research. Moreover, we describe novel and innovative IT-enabled applications, use-cases and techniques in retail financial services as well as in financial investment services. Furthermore, this tutorial identifies the research challenges that need to be addressed for realizing the full potential of innovation in financial services. Examples of such research challenges include context-aware analytics over uncertain and imprecise data, data reasoning and semantics, cognitive and behavioural analytics, design of user-friendly interfaces for improved expressiveness in querying financial service providers, personalization based on fine-grained user preferences and financial Big Data processing on Cloud- based infrastructure.

    • Abstract
      Research shows that over the last decade, malware have been growing exponentially, causing substantial financial losses to various organizations. Different anti-malware companies have been proposing solutions to defend attacks from these malware. The velocity, volume, and the complexity of malware are posing new challenges to the anti-malware community. Current state-of-the-art research shows that recently, researchers and anti-virus organizations started applying machine learning and deep learning methods for malware analysis and detection. We have used opcode frequency as a feature vector and applied unsupervised learning in addition to supervised learning for malware classification. The focus of this tutorial is to present our work on detecting malware with (1) various machine learning algorithms and (2) deep learning models. Our results show that the Random Forest outperforms Deep Neural Network with opcode frequency as a feature. Also in feature reduction, Deep Auto-Encoders are overkill for the dataset, and elementary function like Variance Threshold perform better than others. In addition to the proposed methodologies, we will also discuss the additional issues and the unique challenges in the domain, open research problems, limitations, and future directions.
