About CVC

The Computer Vision Center (CVC) is a non-profit research center established in 1995 by the Generalitat de Catalunya and the UniversitatAutònoma de Barcelona (UAB). Its mission is to carry out cutting-edge research that has the highest international impact in the field of computer vision. It also promotes the transference of knowledge to industry and society.

Computer vision is an exciting research area and an omnipresent technology, essentially empowering machines with the sense of vision. The CVC is a successful marriage between knowledge and innovation. In addition to our cutting-edge scientific achievements, we have established lasting ties with industrial partners and created several spin-off companies.

Research area or group

Research Lab on Image Sequence Evaluation.

Context and Mission

The Computer Vision Center seeks applications to fill a Postdoctoral junior position focused on Information Retrieval and Data Mining.

The selected candidate will collaborate in the project ALETHEIA: Zero Forgetting In Neural Networks: Continual Learning With Anomaly Detection In Image Sequences, on handling misinformation on social media.

The objective of the project is to gain a deep understanding of the phenomenon of dispersion of fake news from start to finish from the perspective of the victims of disinformation. For this, it is proposed to generate a methodology focused on the generation and analysis of data sets (with and without associated verification), applying different techniques and disciplines with a threefold sub-objective: Develop innovative and highly robust models for the characterization of fake news diffusion based on information cascading processes; Generate multimodal data source processing methodologies and tools capable of representing the message in a single vectorial space; and Characterize the messages from a reader's perspective, putting their perception and cognitive response at the centre.
