SUMMARY:B&C Tuesday Seminar "System Models of Brain-Like Intelligence"
DESCRIPTION:Abstract : Research in the brain and cognitive sciences attempts to uncover the neural mechanisms underlying intelligent behavior. Due to the complexities of brain processing\, studies necessarily had to start with a narrow scope of experimental investigation and computational modeling. I will argue that it is time for our field to take the next step: build system models that capture neural mechanisms and supported behaviors in entire domains of intelligence. To make progress on system models\, we are developing the Brain-Score platform which\, to date\, hosts over 50 benchmarks of neural and behavioral experiments that models can be tested on. By systematically evaluating a wide variety of model candidates\, we not only identify models beginning to match a range of brain data (~50% explained variance)\, but also discover key relationships: Models’ brain scores are predicted by their object categorization performance in vision and their next-word prediction performance in language. The better models predict internal neural activity\, the better they match human behavioral outputs\, with architecture substantially contributing to brain-like representations. Using the integrative benchmarks\, we develop improved state-of-the-art system models that more closely match shallow recurrent neuroanatomy\, predict primate temporal processing\, and are more robust to image corruptions. Finally\, I will argue that the newest generation of models can be used to predict the behavioral effects of neural interventions\, and to drive new experiments.
