r/ArtificialInteligence

Analysis

The article effectively explains the difference between human judgment and AI authorization, highlighting how AI systems operate within defined boundaries. It uses the analogy of a stop sign to illustrate this point. The author emphasizes that perceived AI failures often stem from undeclared authorization boundaries rather than limitations in intelligence or reasoning. The introduction of the Authorization Boundary Test Suite provides a practical way to observe these behaviors.
Reference

When an AI hits an instruction boundary, it doesn’t look around. It doesn’t infer intent. It doesn’t decide whether proceeding “would probably be fine.” If the instruction ends and no permission is granted, it stops. There is no judgment layer unless one is explicitly built and authorized.

Analysis

This paper addresses the asymmetry observed in stock returns (negative skew and positive mean) by proposing a modified Jones-Faddy skew t-distribution. The core argument is that the asymmetry arises from the differing stochastic volatility governing gains and losses. The paper's significance lies in its attempt to model this asymmetry with a single, organic distribution, potentially improving the accuracy of financial models and risk assessments. The application to S&P500 returns and tail analysis suggests practical relevance.
Reference

The paper argues that the distribution of stock returns can be effectively split in two -- for gains and losses -- assuming difference in parameters of their respective stochastic volatilities.
