Training ideas

Curricula, sampling schedules, pseudo-labeling and multi-task mixing, with the standard training recipe as the control.

Matrix-Free Krylov Backpropagation Through Solver Layers

Turn an iterative optimization or equilibrium computation inside a neural network into a differentiable layer whose backward pass solves the implicit adjoint system with conjugate gradients or GMRES using only automatic-differentiation matrix-vector products. This avoids storing unrolled iterations and avoids explicit Hessian or Jacobian construction, enabling longer solver horizons and lower-memory implicit architectures.

Phase-Aware Bias-Energy Trust Region

Use the envelope's phase transition to choose whether clipping should primarily control update energy or preserve the raw gradient and reduce clipping bias. In the energy-dominated regime, regulate the retained update energy; in the bias-dominated regime, regulate the removed-gradient residual and monitor rare outliers explicitly.

Self-Supervised Amortized Mean-Field Controller

Train one prompt-conditioned controller to solve a distribution of stochastic control tasks directly from the control objective, instead of generating an optimal trajectory dataset for every task. Use the probability-flow velocity to evolve particles deterministically, evaluate running and terminal costs on those particles, and backpropagate through the rollout to learn a reusable operator.

Fano-Calibrated Multi-User Watermark Budget

Use the paper's attribution converse to calibrate watermark strength and sequence length for a registry of N users, rather than tuning detection and attribution thresholds independently. A dual controller allocates a per-token information and KL budget so that the learned key information approaches the minimum required for reliable attribution, avoiding both underpowered marks and unnecessarily visible perturbations.

Entropy-Gated Surrogate Slopes

Adapt the slope of each spiking neuron's surrogate derivative using the normalized entropy of its block's attention distribution. High centered entropy uncertainty increases the slope, while low uncertainty decreases it, and a dead zone holds the default slope fixed for ordinary fluctuations. The adaptation exists only in backpropagation, so the forward spike function, parameter count, and inference cost remain unchanged.
