Elena Kalinina presents a poster at Rovereto Attention Workshop
At Rovereto Attention Workshop (RAW), Elena Kalinina presented a poster entitled "Shared patterns of object categorization in different cognitive processes: Corss-modal decoding vs. Statistical permutation test", a joint work with F.Pedregosa, V.Iacovella, E.Olivetti e P.Avesani. The question of identifying shared activity patterns between different cognitive processes now is getting addressed in more and more studies. In a common way, to answer this question, a classifier is trained to discriminate stimulus categories in one of the processes and tested on the data from the other. However, the success of this approach often depends on the number of trainign examples available. Besides, decoding is often prone to the "curse of dimensionality". The authors proposed as an alternative to reframe the approach as statistical hypothesis testing and applied it to the data of an fMRI experiment that consisted of three cognitive tasks: Perception, Imagery and Visual Search.
Rovereto Attention Workshop is organized every two years by Mind and Brain Center, University of Trento. This year the workshop focused on “Attention and Brain Fluctuations”. The workshop differs from larger conferences in so far as there are a small number of speakers (all invited) and there are no concurrent talks. In addition to the individual talks, there is be a poster session for students, post-docs and young researchers to present their work.
