"improve the accuracy of Sensors by using a simple Linear Regression model ... for example many Air Quality monitors reporting too high temperature because of the heat generated by the electronics in the enclosure"

@lupyuen nice explanation
based on the quote, we were expecting the surprise to be that the linear regression improves the accuracy by not generating as much waste heat as a more complicated thing it replaced. that would have been amusing.
ah well :D nice explanation regardless
