KEYNOTE TALK 1: Classification with Significant Class Imbalance and Applications in Software Personalization

Professor George Thihrintzis, University of Piraeus, Greece

 

ABSTRACT

Classification is a very common supervised machine learning task, in which a piece of data needs to be assigned by the learning algorithm to one of a given number of potential classes of origin. More specifically, in classification, the machine is given a set of training samples for each of which the class of origin is known. The machine is then asked to learn inductively from the given samples and generalize into a rule for assigning data into classes of origin that allows it to classify samples other than the ones used for training. It is the usual assumption of the binary classification problem that the number of training samples available from one class is comparable to the number of training samples available from the other class. However, it is not uncommon in certain applications for the number of training samples from one class to be significantly higher than the number of training samples from the other class. For example, users of recommender systems are very willing to provide examples (samples) of items they like, but are reluctant to provide samples of items they do not like. Similarly, in a protected system, the number of samples of intruders may be relatively limited, while the number of available samples of allowed/legal users may be quite high. Classification problems with class imbalance arise in nature as well. For example, the immune system in vertebrate organisms needs to be able to discriminate between self cells and other antigens, so as to respond accordingly. A high number of samples from the class of self cells are available to train the immune system. On the other hand, the class of antigens is very broad, including cancer cells, cells from other organisms, molecules and other intruding substances, viruses, bacteria, and parasitic worms. The number of available training samples from the class of antigens is very limited when compared to the size and diversity of this class. The imbalance in the number of samples from each class affects the performance of traditional binary classifiers. Indeed, in probabilistic terms, classification problems in which training samples from one class are significantly higher in number than training samples from the other class result in significantly uneven prior probabilities of the two classes. The class from which a higher number of samples is available (target class) will have higher prior probability, while the class from which only a limited number of samples is available (outlier class) will have much lower prior probability. In turn, this affects the posterior probabilities of a sample coming from one or the other class. As a result, a binary classifier will erroneously tend to decide more often that an unknown sample comes from the target class than from the outlier class. In recommender system applications, this would mean that the system would tend to recommend items that the user might not like. Similarly, in a protected system, intruders and other threats might not be recognized. In this presentation, we will discuss one-class classification problems, i.e, classification problems with extreme class imbalance and investigate the applicability of one-class classification methodologies in the design of recommender systems.

KEYNOTE TALK 2: Rethinking Manufacturing as a Search-Based Service

Dr. Bruce Kramer, Senior Advisor - National Science Foundation, USA

 

ABSTRACT

Many industries have been transformed by tools that give users easy access to service providers, but manufacturing services depend on specialized, expert-to-expert, designer-to-manufacturer negotiations. The presentation will attempt to reframe design as a process that can be driven by an intelligent search of the existing store of parts that have already been manufactured. Each of those parts has a detailed 3D geometrical description, an associated manufacturer and a proven process plan that can be depended on to execute reliably with small parametric variations. An effective search strategy would be a critical breakthrough that resolves longstanding and critical problems with the prevailing generative view of design and manufacturing, which depends on perfecting software systems that unambiguously translate the designs of expert designers into the associated machine instructions for producing them. It is suggested that the search-based approach provides an interesting challenge for the machine learning community and a few speculative approaches will be presented.

KEYNOTE TALK 3: The Evolution of Artificial Intelligence and its Impact to Humanity

Prof. Nikolaos Bourbakis, Wright State University, USA

 

ABSTRACT

The recent advances in Artificial Intelligence have triggered the curiosity of a small number of young scientist to change the way that humanity looks like. The idea of a human body that acts only as the host of the brain and does not perform any other action gains popularity among young AI researchers. In this talk I would like to address these challenges and associated issues and every one has the right to think about them.
