We show experimentally that the accuracy of a trained neural network can be predicted surprisingly well by looking only at its weights, without evaluating it on input data. We motivate this task and introduce a formal setting for it. Even when using simple statistics of the weights, the predictors are able to rank neural networks by their performance with very high accuracy (R2 score more than 0.98). Furthermore, the predictors are able to rank networks trained on different, unobserved datasets and with different architectures. We release a collection of 120k convolutional neural networks trained on four different datasets to encourage further research in this area, with the goal of understanding network training and performance better.

    cs.LG 2026-06 unverdicted novelty 7.0 of 10

    Neural networks admit large families of approximately equivalent solutions via neuron identifiability even without structural symmetry, enabling linear low-loss merging paths without prior alignment.

  2. On the Expressive Power of Permutation-Equivariant Weight-Space Networks

    cs.LG 2026-02 conditional novelty 7.0 of 10

    Permutation-equivariant weight-space networks are all equally expressive, and universality holds when hidden-layer biases are pairwise distinct.

  3. WeightCLIP: Aligning Datasets and Models for Weight Space Learning

    cs.LG 2026-07 conditional novelty 6.0 of 10

    Contrastive dataset–weight alignment reshapes weight-space latents so dataset prompts retrieve, generate, and refine neural nets better than prior weight-space methods.

    cs.LG 2026-04 unverdicted novelty 6.0 of 10

    Gaussian probing infers harmful model specialization from parameter perturbations and internal representation responses to Gaussian latent ensembles rather than from generated outputs.

  6. Dynamic Neural Graph Encoding of Inference Processes in Deep Weight Space

    cs.LG 2026-07 unverdicted novelty 5.0 of 10

    DNG-Encoder represents NN weights as dynamic graphs to preserve sequential inference and powers INR2JLS, which raises INR classification accuracy by ~10% on CIFAR-100-INR.

    cs.LG 2026-05 unverdicted novelty 5.0 of 10

    MVProbe is a multi-perspective probing framework for weight-space learning that combines first-order and Gram-based views and outperforms ProbeX on the Model Jungle benchmark.

  8. Towards Learning Representations of Policies in Two-Player Zero-Sum Imperfect-Information Games

    cs.LG 2026-07 unverdicted novelty 4.0 of 10

    Basic dataset creation, embedding learning, and evaluation tasks on Kuhn and Leduc Poker demonstrate that useful behavioral representations appear in the learned embeddings.

  9. Predicting Deep Neural Network Training Outcomes from Early Training Telemetry

    cs.CL 2026-08 conditional

    After only a few epochs, a run's own loss, accuracy, gradient, and weight-norm telemetry predicts its final accuracy (R² = 0.92 to 0.99) and relative performance (AUC = 0.983 to 0.998) across six image-classification domains.
