Title: Explainable AI through Interpretable Deep Rule-based Learning
Abstract: We are witnessing an explosion of data (streams) being generated and
growing exponentially. Nowadays we carry in our pockets Gigabytes of data in the form
of USB flash memory sticks, smartphones, smartwatches etc. Extracting useful and
human-intelligible/understandable information and knowledge from these big data
streams is of immense importance for the society, economy and science. The
mainstream Deep Learning quickly became a synonymous of a powerful method to
enable items and processes with elements of AI in the sense that it makes possible
human like performance in recognising images and speech. However, the currently used
methods for deep learning which are based on neural networks (recurrent, belief, etc.)
is opaque (not transparent), requires huge amount of training data and computing power
(hours of training using GPUs), is offline and its online versions based on reinforcement
learning has no proven convergence, does not guarantee same result for the same input
(lacks repeatability) and, more importantly, it does not provide insight, transparency (is
a “black-box” type).
In this talk a new, recently introduced approach will be presented which offers highly efficient classifiers, predictive models, etc. but is fully interpretable, transparent and human-intelligible. Moreover, the local optimality as well as the convergence (and respectively, stability) of the proposed systems was theoretically proven and illustrated with examples. The proposed method is prototype-based and non-iterative. It is based on the density and thus it is computationally very efficient (learning on a large amount of images takes few seconds and does not require GPUs or other accelerators as the mainstream deep learning does. However, the performance of the proposed method is on par or better than the competitive alternatives.
The major advantages of this new paradigm is the liberation from the restrictive and often unrealistic assumptions and requirements concerning the nature of the data (random, deterministic, fuzzy), the need to formulate and assume a priori the type of distribution models, membership functions, the independence of the individual data observations, their large (theoretically infinite) number, etc. From a pragmatic point of view, this direct approach from data (streams) to complex, layered model representation is automated fully and leads to very efficient model structures. In addition, the proposed new concept learns in a way similar to the way people learn – it can start from a single example. Thus, the proposed approach is in its nature anthropomorphic.

Title: Technological innovation and its enhancement of cultural heritage
Abstract: The technological revolution which has completely transformed social relations and which has enabled communication and sharing of multimedia formats is also rapidly transforming the field of art and cultural heritage management. This contribution focuses on the innovative use of interactive digital technologies in digital humanities practices. Multimodal interaction modalities have been developed for the exhibition “1525-2015. Pavia, the Battle, the Future. Nothing was the same again”. Visitors could observe and analyze seven ancient tapestries through 3D reconstructions, virtual simulations, eye interaction and gesture navigation, along with transpositions of the tapestries into tactile images that enable the exploration by partially sighted and blind people. Fired by this successful exhibition, a more ambitious project, the 3D reconstruction of Renaissance Pavia, was undertaken. Advanced techniques and innovative applications have led to a resource that has promoted the history of the city and its architectural richness through videos with virtual tours of Renaissance Pavia. In conclusion, an international challenge, namely “Digital Anastylosis of Frescoes (DAF)”, is proposed: the goal is to Develop learning tools that enable digital reconstruction of destroyed frescoes, supporting their restoration, through the solution of ‘puzzles’ formed by their original fragments, often mixed with spurious elements.
