A Novel Strategy for Hybridizing Subsymbolic and Symbolic Learning and Representation
نویسنده
چکیده
One approach to bridging the historic divide between ”symbolic” and ”subsymbolic” AI is to incorporate a subsymbolic system and a symbolic system into a synergetic integrative cognitive architecture. Here we consider various issues related to incorporating (subsymbolic) compositional spatiotemporal deep learning networks (CSDLNs, a term introduced to denote the category including HTM, DeSTIN and other similar systems) into an integrative cognitive architecture including symbolic aspects. The core conclusion is that for such integration to be meaningful, it must involve dynamic and adaptive linkage and conversion between CSDLN attractors spanning sensory, motor and goal hierarchies, and analogous representations in the remainder of the integrative architecture. We suggest the mechanism of ”semantic CSDLNs”, which maintain the general structure of CSDLNs but contain more abstract patterns, similar to those represented in more explicitly symbolic AI systems. This notion is made concrete by describing a planned integration of the DeSTIN CSDLN into the OpenCog integrative cognitive system (which includes a probabilistic-logical symbolic compo-

Beyond Simple Rule Extraction: Acquiring Planning Knowledge from Neural Networks
This paper discusses learning in hybrid models that goes beyond simple classification rule extraction from backpropagation networks. Although simple rule extraction has received a lot of research attention, we need to further develop hybrid learning models that learn autonomously and acquire both symbolic and subsymbolic knowledge. It is also necessary to study autonomous learning of both subsy...
متن کاملRule Induction through Integrated Symbolic and Subsymbolic Processing
We describe a neural network, called RufeNet, that learns explicit, symbolic condition-action rules in a formal string manipulation domain. RuleNet discovers functional categories over elements of the domain, and, at various points during learning, extracts rules that operate on these categories. The rules are then injected back into RuleNet and training continues, in a process called iterative...
متن کاملStatistical Relational Learning - A Logical Approach (Abstract of Invited Talk)
In this talk I will briefly outline and survey some developments in the field of statistical relation learning, especially focussing on logical approaches. Statistical relational learning is a novel research stream within artificial intelligence that combines principles of relational logic, learning and probabilistic models. This endeavor is similar in spirit to the developments in Neural Symbo...

Bridging the gap between symbolic and subsymbolic representations is a – perhaps the – key obstacle along the path from the present state of AI technology to human-level artificial general intelligence. The companion paper (Part II) describes a novel approach to achieiving this bridging via incorporation of a subsymbolic system and a symbolic system into a integrative cognitive architecture. Th...
