Rule-based Out-Of-Distribution Detection
Out-of-distribution detection is one of the most critical issue in the
deployment of machine learning. The data analyst must assure that data in
operation should be compliant with the training phase as well as understand if
the environment has changed in a way that autonomous decisions would not be
safe anymore. The method of the paper is based on eXplainable Artificial
Intelligence (XAI); it takes into account different metrics to identify any
resemblance between in-distribution and out of, as seen by the XAI model. The
approach is non-parametric and distributional assumption free. The validation
over complex scenarios (predictive maintenance, vehicle platooning, covert
channels in cybersecurity) corroborates both precision in detection and
evaluation of training-operation conditions proximity. Results are available

Cognitive networks: brains, internet, and civilizations
In this short essay, we discuss some basic features of cognitive activity at
several different space-time scales: from neural networks in the brain to
civilizations. One motivation for such comparative study is its heuristic
value. Attempts to better understand the functioning of "wetware" involved in
cognitive activities of central nervous system by comparing it with a computing
device have a long tradition. We suggest that comparison with Internet might be
more adequate. We briefly touch upon such subjects as encoding, compression,
and Saussurean trichotomy langue/langage/parole in various environments.Comment: 16 page
An Integrated Conceptual Environment based on Collective Intelligence and Distributed Artificial Intelligence for Connecting People on Problem Solving
This paper aims to analyze the different forms of intelligence within organizations in a systemic and inclusive vision, in order to conceptualize an integrated environment based on Distributed Artificial Intelligence (DAI) and Collective Intelligence (CI). In this way we effectively shift the classical approaches of connecting people with people using collaboration tools (which allow people to work together, such as videoconferencing or email, groupware in virtual space, forums, workflow), of connecting people with a series of content management knowledge (taxonomies and documents classification, ontologies or thesauri, search engines, portals), to the current approaches of connecting people on the use (automatic) of operational knowledge to solve problems and make decisions based on intellectual cooperation. The best way to use collective intelligence is based on knowledge mobilization and semantic technologies. We must not let computers to imitate people but to support people think and develop their ideas within a group. CI helps people to think together, while DAI tries to support people so as to limit human error. Within an organization, to manage CI is to combine instruments like Semantic Technologies (STs), knowledge mobilization methods for developing Knowledge Management (KM) strategies, and the processes that promote connection and collaboration between individual minds in order to achieve collective objectives, to perform a task or to solve increasingly economic complex problems
Challenges in anomaly and change point detection
This paper presents an introduction to the state-of-the-art in anomaly and
change-point detection. On the one hand, the main concepts needed to understand
the vast scientific literature on those subjects are introduced. On the other,
a selection of important surveys and books, as well as two selected active
research topics in the field, are presented
