Beyond Machine Learning: An Fmri Domain Adaptation Model For Multi-Study Integration, Lauryn Michelle Burleigh
LSU Doctoral Dissertations
Traditional machine learning analyses are challenging with functional magnetic
resonance imaging (fMRI) data, not only because of the amount of data that needs to be
collected, adding a particular challenge for human fMRI research, but also due to the change in
hypothesis being addressed with various analytical techniques. Domain adaptation is a type of
transfer learning, a step beyond machine learning which allows for multiple related, but not
identical, data to contribute to a model, can be beneficial to overcome the limitation of data
needed but may address different hypothesis questions than anticipated given the analysis
computation. This dissertation assesses …
The Mechanism Of Directed Forgetting In Visual Working Memory, Katherine Camille Moen
The Mechanism Of Directed Forgetting In Visual Working Memory, Katherine Camille Moen
LSU Doctoral Dissertations
The goal of the current study was to determine if forgetting in visual working memory (VWM) depends on the strength of the memory representations, and to examine different potential mechanisms of directed forgetting in VWM. The strength of memory representations varies depending on factors during encoding and maintenance, which may impact the likelihood of successful forgetting. Experiment 1 manipulated encoding time and cue onset, and utilized eye tracking in order to determine the extent of directed forgetting in VWM. Results support evidence for partial forgetting, and revealed that the strength of memory representations does not impact the likelihood of successful …
