Graph neural induction of value iteration
WebJun 8, 2024 · In this paper, we introduce a generalized value iteration network (GVIN), which is an end-to-end neural network planning module. GVIN emulates the value iteration algorithm by using a novel graph convolution operator, which enables GVIN to learn and plan on irregular spatial graphs. We propose three novel differentiable kernels as graph … Weba key challenge when we are learning over graphs, and we will revisit issues surrounding permutation equivariance and invariance often in the ensuing chapters. 5.1 Neural Message Passing The basic graph neural network (GNN) model can be motivated in a variety of ways.
