The Center for Brains, Minds and Machines
Overview of the Center
Second CBMM Summer School, 2015 The Center for Brains, Minds and Machines
Vision Accumulated knowledge and technology, now in place, enables a rapid leap in our scientific understanding of intelligence and our ability to replicate intelligence in engineered systems.
Mission We aim to create a new field by bringing together computer scientists, cognitive scientists and neuroscientists to work in close collaboration. The new field – the Science and Engineering of Intelligence – is dedicated to developing a computationally centered understanding of human intelligence and to establishing an engineering practice based on that understanding.

16 What is this?
What is Hueihan doing?
What does Hueihan think about Joel’s thoughts about her? Intelligence and Turing++ Questions
• Intelligence —> Human Intelligence
• (Human) Intelligence: one word, many problems
• A CBMM mission: define and “answer” these Turing++ Questions
18 Turing++ Questions
functi onal theor y CB M M th eo ry
The challenge is to develop computational models that answer questions about images and videos such as what is there / who is there / what is the person doing and eventually more difficult questions such as who is doing what to whom? • what happens next? at the computational, psychophysical and neural levels. The who question: face recognition from experiments to theory (Workshop, Sept 4-5, 2015)

The goal of Thrust 1 is to understand the roots of human intelligence o Infants’ early physical representations: Forces and masses o Learning physics from dynamic scenes o Unifying frameworks for intuitive physics beyond rigid, solid objects o Efficiency and experience in infants’ goal representations o Computing Efficiency in Infancy o Efficiency and effort: Bridging intuitive psychology and intuitive physics o Social cognition and the naïve utility calculus o Do children expect others to learn rationally from evidence? o Inference of mental states from emotional expressions o How do children evaluate potential social partners? o Early reasoning about affiliation and kinship o Children’s perception of causal relations across intuitive physics and psychology o Knowing what to look for, in object perception and exploratory learning o Building more sophisticated models of children’s learning in goal-directed search o Lookit: An online developmental lab o Probabilistic programs for scene understanding o Hierarchical motion perception b. Thrust 2
Thrust 2 seeks to discover the neural circuits that answer Turing++ Questions such as “What and who are there? What are they doing?” To achieve this goal, scientists in Thrust 2 record electrical signals from the brains of humans and experimental animals while they are identifying objects and interpreting scenes, and then build computational models of the circuit function.
• Towards a biologically inspired human-level language processing system • Decoding human action and interaction in the human brain • Top-down processes in extracting meaning from images • Task-dependence in visual processing • Neural mechanisms of face detection • Neural circuits underlying navigation • Computational architectures mediating object recognition under occlusion • Biological and computational code underlying pattern completion • Light field Neural Imaging • Expansion Microscopy • Scalable Neural Recording Probes c. Thrust 3
Thrust 3 aims to determine the elements involved in fully understanding visual scenes. Our computational models should be able to extract from the scene information about actions, agents, goals, object configurations, social interactions, and more.

Thrust 4
The goal of Thrust 4 is to understand the capabilities and brain-bases of various aspects of social perception.
• Functional organization of social perception and cognition in the superior temporal sulcus • Face Looking Behavior and Image Statistics for Faces in the Real World • Fast reading of Action Goals • Decoding human action and interaction in the human brain • Understanding intentions and goals in human social interactions from gaze direction e.
