Title: Cognitive Architecture for Operant Conditioning

Venue: Science Bldg. II, Room 102
Time & Date : 20th June 11 am

Abstract
In this talk, I will present my research on cognitive architecture for operant conditioning. To lay the foundation for the discussion, I will start by reviewing the definitions and tests for AI and propose a new definition and the test for human-level intelligence (HLI). I claim that the essence of HLI to be the capability to learn from others’ experiences via language. Based on the definition, I propose the test for HLI would be the language acquisition task and present the simulated environment to run the test practically. A next milestone toward HLI would be enabling operant conditioning inspired by the ‘Skinner box’ experiment. To achieve this goal, I will explain two lessons that we can learn from the biological brain. First, the working principle of neocortex can be modeled as Modulated Heterarchical Prediction Memory (mHPM). In mHPM, autoregressive universal modules are connected in a heterarchical network, and they are update in a local and distributed way instead of current deep learning trend of end-to-end optimization based on the single objective function. Second lesson is that we need non-homogeneous cognitive architecture for innate and learned behaviors instead of current homogeneous architecture. I will explain the role of innate components such as hippocampus, reward system, hypothalamus, and amygdala.
