ElectricalTrends article discussing the relationship between data quality and AI performance, drawing on an industry panel discussion about data governance and digital integrity.
Help Net Security summarizes the SANS 2026 threat hunting survey: 50% of respondents named data quality as the top barrier, ahead of skilled staff (45%) and budget (42%). Survey figures are self-reported by practitioners.
The free research library and blog of Snorkel AI, the company spun out of Stanford's Snorkel project on programmatic labelling. The papers and posts explain how training data for AI models is actually built — labelling, evaluation sets, and the 'environments' used to train agents. Useful if you want to understand the unglamorous data work behind model quality, which is where a lot of the real jobs are.
Why I recommend it: Research and blog posts are free to read with no signup. Read it for the how, not the verdict: Snorkel sells data services to frontier AI labs, so posts arguing that better data beats bigger models are also a sales case. Everything else on the site is a paid enterprise product — 'request dataset samples' means a sales call.
