NeuralVerification.jl

This library contains implementations of various methods to soundly verify deep neural networks. In general, we verify whether a neural network satisfies certain input-output constraints. The verification methods are divided into five categories: * Reachability methods: ExactReach, MaxSens, Ai2,

• Primal optimization methods: NSVerify, MIPVerify, ILP

• Dual optimization methods: Duality, ConvDual, Certify

• Search and reachability methods: ReluVal, Neurify, DLV, FastLin, FastLip

• Search and optimization methods: Sherlock, BaB, Planet, Reluplex

Installation

To download this library, clone it from the julia package manager like so:

julia
(v1.0) pkg> add https://github.com/sisl/NeuralVerification.jl

Please note that the implementations of the algorithms are pedagogical in nature, and so may not perform optimally. Derivation and discussion of these algorithms is presented in the survey paper linked above.

Note: At present,

Ai2

ExactReach

Duality

The implementations run in Julia 1.0.

Example Usage

Choose a solver

using NeuralVerification

solver = BaB()

Set up the problem

nnet = read_nnet("examples/networks/small_nnet.nnet")
input_set  = Hyperrectangle(low = [-1.0], high = [1.0])
output_set = Hyperrectangle(low = [-1.0], high = [70.0])
problem = Problem(nnet, input_set, output_set)

Solve

julia> result = solve(solver, problem)
CounterExampleResult(:violated, [1.0])

julia> result.status
:violated
