I use Chebyshev polynomials extensively in finance and have tried problems like MNIST with Chebyshev and they get close to CNNs in accuracy. ApproxFun Julia package pretty cool for Chebyshev work: https://juliaapproximation.github.io/ApproxFun.jl/latest/

What do you mean by close to CNN?

What is your architecture? Is it just a fully connected layer of chebyshev?
