Jacek Koronacki "Empirical Model Building with Monte Carlo Feature Selection and Interdependence Discovery"
We argue that the model-free Exploratory Data Analysis or Data Mining can be used to advantage as the first stage of a two-stage data-driven causal reasoning process. We illustrate this by example - why our Monte Carlo Feature Selection and Interdependencies Discovery algorithm is a useful tool for such two-stage approach.

Zbigniew Michalewicz was one of the editors-in-chief of the Handbook of Evolutionary Computation and the general chairman of the First IEEE International Conference on Evolutionary Computation held in Orlando, June 1994. In December 2013 Zbigniew was awarded (by the President of Poland, Mr. Bronislaw Komorowski) the Order of the Rebirth of Polish Polonia Restituta – the second highest Polish state decoration civilian for outstanding achievements in the field of education, science, sports, culture, arts, economy, national defence, social activities, the civil service and the development of good relations with other countries.
The talk would cover a few AI-based business applications for transforming data into decisions, based on work done for three companies (NuTech Solutions, SolveIT Software, and Complexica) over the last 20 years. A few general concepts (Adaptive Business Intelligence, Travelling Thief Problem, Larry – the Digital Analyst) would be discussed and illustrated by a few examples. The final part of the talk would present Complexica’s approach for increasing revenue, margin, and customer engagement through automated analysis.
Witold Pedrycz "From Data to Information Granules: Quantitative and Qualitative Facets of AI"
Systems Research Institute, Polish Academy of Sciences, Warsaw, Poland
In retrospect, over years Artificial Intelligence (AI) has exhibited facets of qualitative (symbolic) and sub-symbolic (numeric) knowledge representation, reasoning, and modeling. At the symbolic end of the spectrum of AI constructs, it becomes imperative to form symbols so that they are well aligned (grounded) with real-world experimental data and in this way become a sound abstraction and perception of the world.
In this study, we advocate that information granules, both in terms of their conceptual underpinnings and associated design constructs, offer a required environment supporting a transition from data to a collection of symbols and delivering a required level of abstraction.
The overall functional schemed outline here can be concisely portrayed in the form
data -› structure (clusters) -› granular clusters -› granular schemes of modeling and reasoning
where a buildup of information granules supports generative and discriminative aspects of clusters regarded as generic constructs. While clustering algorithms give rise to numeric constructs (say, prototypes and partition matrices, etc.) and with this regard exhibit a long tradition, a paradigm shift becomes inevitable. We propose here an attractive alternative of symbolic (qualitative) characterization of information granules (clusters), which supports higher levels of interpretability and offers insights into aspects of conceptual stability of structural findings. It also links a level of information granularity (abstraction) with the stability of symbols and emphasizes the duality of interpretation of information granules as exhibiting their duality of symbolic (syntactic) and semantic nature. Those aspects are directly aligned with qualitative modeling and qualitative reasoning researched intensively in the AI domain. We discuss a direction of research aimed at building optimal information granules and their abilities to represent the data. It is argued that when coping with distributed environment (say, multiagent systems), information granules of higher type and higher order become of interest.

Shannon's information theory has served as a bedrock for advances in communication and storage systems over the past five decades. However, this theory does not handle well higher order structures (e.g., graphs, geometric structures), temporal aspects (e.g., real-time considerations), or semantics. We argue that these are essential aspects of data and information that underly a broad class of current and emerging data science applications. In this talk, we present some recent results on structural and temporal information. We first show how to extract temporal information in dynamic networks (arrival of nodes) from its structure (unlabeled graphs). We then proceed to establish fundamental limits on information content for some data structures, and present asymptotically optimal lossless compression algorithms achieving these limits for various graph models.
We use these examples to motivate our view on data science. Our approach brings information to the center of the theoretical foundations of information and data science. In sum, we argue that the unifying theme of data science should be the triad: from data to information to knowledge.

Since the concept of Turing machine has been first proposed in 1936, the capability of machines to perform intelligent tasks went on growing exponentially. Artificial Intelligence (AI), as an essential accelerator, pursues the target of making machines as intelligent as human beings. It has already reformed how we live, work, learning, discover and communicate. In this talk, I will review our recent progress on AI by introducing some representative advancements from algorithms to applications, and illustrate the stairs for its realization from perceiving to learning, reasoning and behaving. To push AI from the narrow to the general, many challenges lie ahead. I will bring some examples out into the open, and shed lights on our future target. Today, we teach machines how to be intelligent as ourselves. Tomorrow, they will be our partners to step into our daily life.
