Closing the Loop: Automated Data-Driven Cognitive Model Discoveries Lead to Improved Instruction and Learning Gains

Ran Liu, Kenneth R. Koedinger
2017 Zenodo  
Here, we present an instance of "closing the loop" on an automated cognitive modeling improvement discovered by Learning Factors Analysis (Cen, Koedinger, and Junker, 2006).  ...  Educational data mining seeks to analyze and model these data, with the ultimate goal of improving learning outcomes.  ...  It is also one of relatively few efforts to "close the loop" on educational data mining discoveries more generally.  ...

The Collation and Use of Data from Continuous Remote Monitoring Systems for the Control of Sound Emissions from a Large Industrial Noise Source

Tim Procter, Stephen Lyons
2019 Proceedings of the ICA congress  
Using traditional closed-loop control theory, this paper shows how the analysis of the sound emissions from the constantly changing environs of a large open-cut mine identified the source of a time lag  ...  As a result, a new control strategy based on SMART technology has been developed to reduce the error signal time lag and help improve the control of noise emanating from the mine.  ...  emitted by the mine is represented as a closed-loop feedback control system in Figure 2 .  ...
