# Gradient Descent Converges to Cycles in Non-Separable Logistic Regression

Research shows gradient descent converges to stable cycles rather than minima in non-separable logistic regression with large step sizes.

For linearly-separable data, gradient descent is known to converge to the minimizer with arbitrarily large step sizes. [^1]

The study investigates gradient descent dynamics on logistic regression problems utilizing large, constant step sizes. [^2]

This convergence property no longer holds when the logistic regression problem is not separable. [^3]

Developers commonly treat AGENTS.md or CLAUDE.md files as simple README documents containing static rules for AI coding agents. [^4]

The article proposes a conceptual framework where AGENTS.md files are viewed as neural networks rather than just static configuration. [^5]

A sequence of period-doubling bifurcations begins at the critical step size of 2 divided by lambda, where lambda is the largest eigenvalue of the Hessian at the solution. [^6]

The author suggests that gradient descent could be utilized as a training method for these AI agent configurations. [^7]

The content implies that current rule-based approaches may be insufficient compared to trainable network models. [^8]
