Pattern functional dependencies for data cleaning

Abdulhakim Qahtan, Nan Tang, Mourad Ouzzani, Yang Cao, Michael Stonebraker
2020 Proceedings of the VLDB Endowment  
Inspired by the above observation, we propose a novel class of ICs, called pattern functional dependencies (PFDs), to model fine-grained data dependencies gleaned from partial attribute values.  ...  widely used in data cleaning.  ...  Selecting PFDs The discovery of ICs is a data-driven mining approach with no guarantee that the discovered ICs are genuine.  ...

my monstituces composer: Looking for the Pre-Emergent Social Consciousness of AI in Small Data Literary Synthesis

Nathan Allen Jones
2020 Media-N, Journal of the New Media Circus  
I close-read the odd language-salad of the texts written by this "small data synthesis" glitch method in order to discern whether there is a "structure of feeling" (Williams) in them: a pre-emergent sign  ...  of a social being-to-come.  ...  Quantitative approaches to language such Parrish's and OpenAI's may share a pre-emergent social quality in this context.  ...
