Karpathy says engineering moves up from the model to the graph

Karpathy’s framing puts the engineering stack on a path from model to prompt, agent, loop and graph, and he suggested a Markdown wiki maintained by a language model.

Wolfe says recursive self-improvement bundles three separate ideas

Wolfe distinguished automation of research, the pace of progress and the degree of human understanding and control, and argued the scenarios can come apart.

Critics say the Astra weights post merges different techniques

Matthew Honnibal says the MIT post mixes raw-weight reading with Python tooling, while Simon Willison showed a laptop model can identify some games from raw weights.

Lower Bounds on Inference Complexity for Polyak-Ruppert Averaged Stochastic Gradient Descent

Belomestny et al.

For step sizes with exponent \(\gamma\in(1/2,1)\), the Gaussian approximation error has order \(n^{1/2-\gamma}+n^{\gamma-1}\), matching the known upper bound.

Non-asymptotic analysis of SGLD with discontinuous stochastic gradients: a new route to portfolio CVaR minimization

Ding et al.

For regularised conditional value at risk, stochastic gradient Langevin dynamics converges in Wasserstein-2 distance at rate \(\mathcal{O}(\lambda^{1/4})\) in the step size, with excess risk linear in the number of assets.

Gronich and Vardi

For a schedule \(t^{\alpha}\) and homogeneity degree \(L\), when \(\alpha>\frac{1}{L}-\frac{1}{2}\) Adam has no trajectory-independent margin-maximisation bias on deep linear networks.
