For adults with disabilities who are experiencing homelessness, chances of being approved for social security disability benefits are very low, without assistance. Assisting with the Supplemental Security Income (SSI)/Social Security Disability Insurance (SSDI) application process can be challenging for case managers who lack capacity and expertise. Training caseworkers to document disability a...

This chapter reports progress in extending the Soar architecture to tasks that involve interaction with external environments. The tasks are performed using a Puma arm and a camera in a system called Robo-Soar. The tasks require the integration of a variety of capabilities including problem solving with incomplete knowledge, reactivity, planning, guidance from external advice, and learning to i...

Calcium influx through the Ca(2+) release-activated Ca(2+) (CRAC) channel is an essential process in many types of cells. Upon store depletion, the calcium sensor in the endoplasmic reticulum, STIM1, activates Orai1, a CRAC channel in the plasma membrane. We have determined the structures of SOAR from Homo sapiens (hSOAR), which is part of STIM1 and is capable of constitutively activating Orai1...

The last decade has seen the emergence of a variety of cognitive architectures. This is good news, in general, for cognitive modeling, because architectures provide a readymade set of tools and theoretical constraints that can— according to architectural research methodology—assist the cognitive modeling enterprise by constraining the possible models of a set of phenomena or even making the “ri...

Incorrect knowledge can be a problem for any intelligent system. Soar is a proposal for the underlying architecture that supports intelligence. It has a single representation of long-term memory and a single learning mechanism called chunking. This paper investigates the problem of recovery from incorrect knowledge in Soar. Recovery is problematic in Soar because of the simplicity of chunking: ...

This paper describes the development of a system that uses computational psychology (the Soar cognitive architecture) for the control of unmanned vehicles. A multithreaded software system written using Java and integrated with the Soar cognitive architecture has been implemented on two types of mobile robots. Soar can be used as a general purpose robotic intelligence system and can handle a wid...

This paper presents SOAR: the first oblivious atomicity assertion with polynomial complexity. SOAR enables to check atomicity of a single-writer multi-reader register implementation. The basic idea underlying the low overhead induced by SOAR lies in greedily checking, in a backward manner, specific points of an execution where register operations could be linearized, rather than exploring all p...

Emerging scientific workflows in HPC focus more on analysis rather than simulation. Simulation output is so dense with information that copious amounts of analysis must be performed on a single output to understand the results of that simulation. We identify this repetitive analysis as a new application type, Simulate Once Analyze Repeatedly (SOAR) Computing. Current scientific HPC, when extend...

Our long-term goal is to develop autonomous robotic systems that have the cognitive abilities of humans, including communication, coordination, adapting to novel situations, and learning through experience. Our approach rests on the recent integration of the Soar cognitive architecture with both virtual and physical robotic systems. Soar has been used to develop a wide variety of knowledge-rich...

In past work, chunking in Soar has been analyzed as a variant of explanation-based learning. The components and processes underlying EBL have been mapped to their corresponding components and processes in chunking. The cost and generality of the resulting rules have also been compared. Here we extend that work by analyzing an implementation of EBL within Soar as a sequence of transformations fr...
