XOR problem solvable with 2x2x1 neural network without bias?

Question

Is a Neural network with 2 input nodes, 2 hidden nodes and an output supposed to be able to solve the XOR problem provided there is no bias? Or can it get stuck?

Answer 1

I have built a neural network without bias and a 2x2x1 architecture solves XOR in 280 epochs. Am new to this, so didn't know either way, but it works, so it is possible.
