WhestBench 2026: ARC White-Box Estimation Challenge

Organized by: Alignment Research Center (ARC), AIcrowd WhestBench 2026: ARC White-Box Estimation Challenge WhestBench is a benchmark for white-box activation estimation: given the weights of a small ReLU multi-layer perceptron (MLP) and a strict floating-point-operation (FLOP) budget, predict the average post-activation value of every neuron when the network is fed standard Gaussian inputs.This is the train dataset for WhestBench 2026 —… See the full description on the dataset page:
