Binary Quantized Neural Network Training Proven W[1]-Hard

By PulseAugur Editorial · [1 sources] ·

Researchers have demonstrated that training binary quantized neural networks is W[1]-hard when parameterized by input and output dimensions. This finding indicates that the problem does not admit a fixed-parameter tractable algorithm based solely on these dimensions, contrary to a previous hypothesis. The hardness arises from a one-flip routing equivalence, where fitting data exactly becomes as difficult as disjoint-path routing, limiting what individual neurons can do locally but not how they must share resources globally.

    Binary Quantized Neural Network Training Is W[1]-Hard Parameterized by Input and Output Dimensions

    arXiv:2609.27932v2 Announce Type: replace Abstract: When the weights and biases of a neural network range over a fixed finite alphabet, training the network to fit a data set exactly becomes a finite combinatorial problem, and parameterized complexity asks which structural quanti…
