Researchers have identified new theoretical boundaries for the tractability of training neural networks, particularly for networks with linear and ReLU activation functions. For ReLU networks, they've established polynomial-time tractability for architectures where hidden neurons have an out-degree of 1. Additionally, for linear activation functions, they've defined the first non-trivial polynomial-time solvable class of networks by developing an algorithm for architectures that meet a novel data throughput condition.
