Task Details of the 5th Whole Brain Architecture Hackathon

  1. 1. The 5th Whole Brain Architecture Hackathon Task Details June 2021 The Whole Brain Architecture Initiative & Cerenaut
  2. 2. Delayed Match-to-Sample Task
  3. 3. Delayed Match-to-Sample Task A sample is shown After the sample disappears, two figures are shown. The agent is to select ‘the same’ figure. Agent has to remember the sample. Working Memory!
  4. 4. The sample and target may not be exactly the same. The shape is the same, but the color, orientation, and size may change.
  5. 5. These are the same! Same colour!
  6. 6. Bar position task To remember where the bar in the sample was
  7. 7. Exemplar (Tutoring) sessions To show the agent which game to play before actual game play, i.e. which feature to attend: ● shape ● colour ● bar position
  8. 8. Non-Delayed Match-to-Sample Task and Active Vision
  9. 9. Non-Delayed Match-to-Sample Tasks are basically the same as their delayed versions, but without delay. So, they are easier than delayed ones.
  10. 10. Central/Peripheral Vision and Active Vision ● We cannot look at separated objects at the same time in detail. ● Only the center of the visual field (fovea) has high resolution. ● So, we have to move the eye to look at objects. ⇒ active vision
  11. 11. ● The agent has to move the eye to compare the target with the sample, because of the central/peripheral vision. ● So, it has to remember two objects to compare ⇒ They also require working memory! Active Vision and Non-Delayed Match-to-Sample Tasks
  12. 12. Task Score Non-delayed shape 60 Non-delayed color 20 Non-delayed bar position 20 Delayed shape 120 Delayed color 40 Delayed bar position 40 Total 300 Scoring Details
