Inter-model Interpretability: Self-supervised Models as a Case Study [article]

Ahmad Mustapha, Wael Khreich, Wes Masri
2022 arXiv   pre-print
Since early machine learning models, metrics such as accuracy and precision have been the de facto way to evaluate and compare trained models.  ...  A model with high accuracy on a certain dataset might provide a lower accuracy on another dataset, without any further insights.  ...  As a case study, we projected the 13 top-performing self-supervised deep learning models into the LCE embedding 3 .  ...

Wood and Comfort: A Comparative Case Study of Two Multifunctional Rooms

Mélanie Watchman, André Potvin, Claude M. H. Demers
2016 BioResources  
Analysis of instrumental measurements and images of each room's indoor environment under overcast skies determined the colour and texture of the surfaces.  ...  The colour, knots, and grain of the wood contributed to producing visually warm experiences resulting in a yellowish room, whereas a mix and match of artificial finishes generates a colder, bluish ambiance  ...  The CIE L*a*b* colour model (Lab) evaluates Colour Temperature (CT) by numerically describing the colours that a non-visually impaired person sees.  ...
