Statistical Foundations

Understanding how statistical moments connect the mean, variance, and higher powers of a distribution remains essential for practitioners, and a new deep dive explores the hidden silhouette of data through this lens. Meanwhile, one practitioner measured exactly how many labeled examples a text classifier actually needs, finding that a decades-old baseline can already do substantial work before reaching for an LLM API on every classification problem. A separate analysis argues that MSE metrics mislead in probabilistic forecasting for physical signals, opening a series on what happens when forecasts roll forward more than one step.

Industry & Funding

MIT Technology Review's daily Download covers AI doomers, whistleblowing agents, and de-aged livers. A separate report details how OpenAI is paying to create more biological data for AI models, following policy analyst Ruxandra Teslo's idea to bid on data from failed biotech companies at bankruptcy proceedings. On the economics side, Wharton finance professor Jessica Wachter assessed what must happen for AI's trillion-dollar gamble to pay off, working through a long list of business and economic variables.
