+ | The activity in this research theme has mainly focused on the development of methods and algorithms | ||
+ | exploiting ideas and techniques from machine learning, data mining, natural language processing, and artificial | ||
+ | intelligence for extracting novel, useful information and knowledge from data. Many kinds of data have been | ||
+ | considered, ranging from structured data in tabular form (records with numerical and/or categorical attributes) | ||
+ | to unstructured data such as text in natural language, graphs (as diverse as social networks, see | ||
+ | also FORUM theme, gene regulatory networks, and linked data) and multimedia data, including time | ||
+ | series (e.g., electrocardiographic signals), images, videos and 3D data. | ||
+ | The methods and techniques used include support-vector machines, neural networks, | ||
+ | boosting, decision trees, random forests, frequent pattern and association rule mining , inductive logic programming, fuzzy set theory, and evolutionary algorithms. | ||
+ | A particular emphasis has been given to the scalability of the approaches, according to three dimensions: | ||
+ | - the volume of the data that are to be processed; | ||
+ | - the number of processing units available for computation and the distributed nature of both data and algorithms; | ||
+ | - the computational power of the processing units, which may become critical when the proposed approaches must be embedded in appliances, vehicles, or mobile devices, often with tight resource consumption constraints. | ||
