There was a problem hiding this comment.
Don't store a vector here. Instead pass in a initialization_function (ideally from WeightInitializers.jl) and construct the vector inside initialstates

PositiveDefinitecontainer wraps an underlying model and results in a model that returns a postive number whenever the input is nonzero (or not equal to a different point specified when defining the container). This is useful, among other applications, in neural Lyapunov applications.
