DeepEquilibriumNetworks

DeepEquilibriumNetworks.jl is a framework built on top of DifferentialEquations.jl and Lux.jl enabling the efficient training and inference for Deep Equilibrium Networks (Infinitely Deep Neural Networks).

Installation

using Pkg
Pkg.add("DeepEquilibriumNetworks")

Quickstart

using DeepEquilibriumNetworks, Lux, Random, NonlinearSolve, Zygote, SciMLSensitivity
# using LuxCUDA, LuxAMDGPU ## Install and Load for GPU Support. See https://lux.csail.mit.edu/dev/manual/gpu_management

seed = 0
rng = Random.default_rng()
Random.seed!(rng, seed)

model = Chain(Dense(2 => 2),
    DeepEquilibriumNetwork(
        Parallel(+, Dense(2 => 2; use_bias=false), Dense(2 => 2; use_bias=false)),
        NewtonRaphson()))

gdev = gpu_device()
cdev = cpu_device()

ps, st = Lux.setup(rng, model) |> gdev
x = rand(rng, Float32, 2, 3) |> gdev
y = rand(rng, Float32, 2, 3) |> gdev

model(x, ps, st)

gs = only(Zygote.gradient(p -> sum(abs2, first(model(x, p, st)) .- y), ps))
