WebWe propose a novel neural network layer, the hierarchical lattice layer (HLL), as an extension of the lattice layer so that we can use a standard stochastic gradient descent algorithm to train HLL while satisfying monotonicity constraints and so that it can receive a high-dimensional input vector. Webearly constrained neural network" proposes a DNN that produces a vector field whose curl is di-vergence free [22]. It is thus also possible to construct a scalar field whose gradients are curl free. Actually, a general method has been developed to construct neural networks with linear constraints.

WebStochastic Gradient Descent (SGD) is the default workhorse for most of today's machine learning algorithms. While the majority of SGD applications is concerned with Euclidean spaces, recent advances also explored the potential of Riemannian manifolds.
