Title of Speech: Constructive preference learning through robust ordinal regression 

Abstract: We present a constructive preference learning methodology, called Robust Ordinal Regression, for Multiple Criteria Decision Aiding. Identification of Decision Maker’s (DM’s) preferences is a crucial step in decision aiding. It is known that the dominance relation established in the set of alternatives evaluated on multiple criteria is the only objective information that comes from the formulation of a multiple criteria decision problem (ordinal classification, or ranking, or choice – with multiobjective optimization being a particular case). While it permits to eliminate many irrelevant (i.e., dominated) alternatives, it does not compare completely all of them, resulting in a situation where many alternatives remain incomparable. This situation may be addressed by taking into account preferences of the DM. Therefore, decision aiding methods require some preference information elicited from a DM or a group of DMs. This information is used to build more or less explicit preference model, which is then applied on a non-dominated set of alternatives to arrive at a recommendation presented to the DM. In practical decision aiding, the process composed of preference elicitation, preference modeling, and DM’s analysis of a recommendation, loops until the DM accepts the recommendation or decides to change the problem setting. Such an interactive process is called constructive preference learning. We will focus on processing DM’s preference information concerning multiple criteria ranking and choice problems. This information has the form of pairwise comparisons of selected alternatives, and/or comparisons of intensities of preference between pairs of some alternatives. Research indicates that such preference elicitation requires less cognitive effort from the DM than direct assessment of preference model parameters (like criteria weights, comparison thresholds, or trade-offs between conflicting criteria). We will describe how to construct from this input information a preference model being a utility function or an outranking relation, via Robust Ordinal Regression (ROR). An important feature of ROR is identification and use of all instances of the preference model that are compatible with the input preference information – this permits to draw robust conclusions in terms of necessary and possible relations in the set of considered alternatives. The methodology will be presented along with some examples of their application.

Title of Speech: Research Advance in Swarm Intelligence and Fireworks Algorithm 

Abstract: Recently, inspired from the collective behaviors of many swarm-based creatures in nature or social phenomena, swarm intelligence (SI) has been received attention and studied extensively, gradually becomes a class of efficiently intelligent optimization methods. Inspired by fireworks explosion at night, the fireworks algorithm (FWA) was developed in 2010. Since then, several improvements and some applications were proposed to improve the efficiency of FWA. In this talk, after brief introduction of swarm intelligence, the fireworks algorithm is reviewed in detail, then several effective improved fireworks algorithms are highlighted individually. By changing the ways of calculating numbers and amplitudes of sparks in fireworks’ explosion, the improved FWA algorithms become more reasonable and explainable. In addition, the multi-objective fireworks algorithm and the graphic processing unit (GPU) based FWA are also briefly presented, particularly the GPU-based FWA is able to speed up the optimization process considerably. Extensive experiments on IEEE-CEC’s benchmark functions demonstrate that the improved fireworks algorithms significantly increase the accuracy of found solutions, yet decrease the running time dramatically. Finally, some applications of FWA are briefly described, in particular, the applications of FWA to some important optimization problems happened in material engineering filed are highlighted and reviewed in details. I believe that the FWA will find its right way in the field of material engineering in future.

Title of Speech: User Authentication by Means of Handwriting - Recent Advances and Open Problem 

Abstract: User authentication is actually required in many situations in our everyday life. Examples include the login to e-banking or e-mail accounts, the registration to a webshop, or online payments with a credit card. Authentication systems can be broadly classified into the following three categories.
- Knowledge based systems rely on something the user knows (e.g. a password).
- Possession based systems rely on something the user has (e.g. an ID-Card).
- Inherence based systems rely on physiological traits of the user (e.g. a fingerprint).
The present talk is focused on an authentication systems based on handwritten signatures as a physiological trait of users (i.e. we focus on inherence based systems). Signature verification is often based on only few genuine specimens and is thus regarded as a challenging task (even for humans). Yet, the current state-of-the-art achieves a high level of accuracy which is comparable to that of other biometric authentication frameworks. Moreover, with the recent rise of mobile devices equipped with sophisticated touch-sensitive screens, signatures can easily be acquired in a noninvasive way. In this particular scenario several dynamic characteristics, such as writing speed, acceleration, or pen pressure are also available for recognition (known as online signatures). This talk gives a survey on recent methods for online signature verification and provides a comprehensive comparison of two prominent string matching algorithms that can be readily used for signature verification. Moreover, it presents a novel cost model for string matching which turns out to be particularly well suited for the task of signature verification. The talk also provides some use case scenarios of this particular framework and concludes with several open research problems in the field of user authentication by means of handwriting.
