Action detection and temporal segmentation of actions in videos are topics of increasing interest. While fully supervised systems have gained much attention lately, full annotation of each action within the video is costly and impractical for large amounts of video data. Thus, weakly supervised action detection and temporal segmentation methods are of great importance. While most works in this ...

Agent’s meta-reasoning is a computational process that implements agent’s capability to reason on a higher level about another agent or a community of agents. There is a potential for meta-reasoning in multi-agent systems. Meta-reasoning can be used for reconstructing agents’ private knowledge, their mental states and for prediction of their future courses of action. Meta-agents should have the...

Radioiodinated meta iodobenzylguanidine (MIBG) is one of the important radiopharmaceuticals in Nuclear Medicine. [123/131I]MIBG is used for imaging of Adrenal medulla, studying heart sympathetic nerves, treatment of pheochromacytoma and neuroblastoma. For clinical application, radioiodinated MIBG is prepared through isotopic exchange method, which includes replacement of radioactive iodine in a...

This paper presents a web-based system that supports students in their learning of phonetic transcription and production. It allows students to create their own exercises from an integrated database of recordings, according to their specific learning needs. Every recording in the system has been meta-tagged. For example, a cardinal vowel will have, among others, the tags ‘vowel’ and ‘cardinal’....
