Baby X Flashcards
Why is modeling the brain computationally useful?
Computer models can capture the brain’s complexity, generate expected behaviors, and respect known constraints of the brain’s architecture.
What are some challenges in modeling a whole person?
People perform many parallel tasks (perceiving, acting, remembering, planning, emotions, social interaction), requiring a model to capture this multitasking.
What is Baby X?
Baby X is an AI model simulating a baby’s cognitive development in a holistic, embodied way, with a graphical body that perceives, reaches for objects, and interacts with a caregiver.
How does Baby X model vision?
Baby X models pathways for early vision (thalamus, occipital lobe) and visual attention (parietal, frontal lobes), builds saliency maps, and classifies attended objects.
What allows Baby X to exhibit both bottom-up and top-down attention?
Bottom-up attention is driven by salient stimuli, while top-down attention is goal-oriented, like searching for a specific object
How does Baby X model motor control?
Baby X models motor pathways from motor cortex to muscles, requiring attention to the target object before reaching or grasping.
What does Baby X simulate in its reach/grasp actions?
Baby X simulates touch signals and slip detection when reaching for and grasping objects
How are emotions modeled in Baby X?
Baby X models subcortical circuits like the amygdala and neurotransmitters like oxytocin, with emotions influencing behavior, expressions, physiology, and learning.
How does Baby X learn object categories in vision?
Baby X learns object categories through supervised learning on neural network classifiers.
What learning mechanism does Baby X use for motor control?
Baby X learns action sequences that lead to rewards through reinforcement learning.
How does Baby X learn emotional responses?
Baby X learns conditioned responses to emotionally salient stimuli.
Is Baby X a nativist, empiricist, or interactionist model of development?
Baby X is an interactionist model, having innate machinery to enable learning across domains.
Is Baby X a global or local model of development?
Baby X is a local model, with different cognitive components developing along their own trajectories.
What is the long-term goal for Baby X?
The long-term goal is to model a full developmental trajectory from baby to adult.
How does Baby X aim to study intelligent behavior?
Baby X brings together innate and learning mechanisms across vision, motor, emotion, and other domains starting from infancy to study how their interactions produce intelligent behavior.
